315 nuclear bombs and ongoing suffering: The shameful history of nuclear testing in Australia and the Pacific

<p><em>Aboriginal and Torres Strait Islander people should be aware this article contains the name of a deceased person.</em></p> <p>The Treaty on the Prohibition of Nuclear Weapons received its <a href="https://news.un.org/en/story/2020/10/1076082">50th ratification on October 24</a>, and will therefore come into force in January 2021. A historic development, this new international law will ban the possession, development, testing, use and threat of use of nuclear weapons.</p> <p>Unfortunately the nuclear powers — the United Kingdom, France, the United States, Russia, China, Israel, India, Pakistan and North Korea — haven’t signed on to the treaty. As such, they are not immediately obliged to <a href="http://hrp.law.harvard.edu/wp-content/uploads/2018/04/Victim-assistance-short-4-8-18-final.pdf">help victims and remediate contaminated environments</a>, but others party to the treaty do have these obligations. The shifting norms around this will hopefully put ongoing pressure on nuclear testing countries to open records and to cooperate with accountability measures.</p> <p>For the people of the Pacific region, particularly those who bore the brunt of nuclear weapons testing during the 20th century, it will bring a new opportunity for their voices to be heard on the long-term costs of nuclear violence. The treaty is the first to enshrine enduring commitments to addressing their needs.</p> <p>From 1946, around <a href="https://icanw.org.au/wp-content/uploads/Pacific-Report-2017.pdf">315 nuclear tests</a> were carried out in the Pacific by the US, Britain and France. These nations’ largest ever nuclear tests took place on colonised lands and oceans, from Australia to the Marshall Islands, Kiribati to French Polynesia.</p> <p>The impacts of these tests are still being felt today.</p> <p><strong>All nuclear tests cause harm</strong></p> <p>Studies of nuclear test workers and exposed nearby communities <a href="https://www.ctbto.org/nuclear-testing/">around the world</a> <a href="https://www.cambridge.org/core/journals/international-review-of-the-red-cross/article/humanitarian-impact-and-implications-of-nuclear-test-explosions-in-the-pacific-region/1FDB0D26842BEA5621F33A0B53FCD7F9">consistently show</a> adverse health effects, especially increased risks of <a href="https://www.ctbto.org/nuclear-testing/">cancer</a>.</p> <p>The total number of global cancer deaths as a result of atmospheric nuclear test explosions has been estimated at between <a href="https://scope.dge.carnegiescience.edu/SCOPE_59/SCOPE_59.html">2 million</a> and <a href="https://ieer.org/wp/wp-content/uploads/1991/06/RadioactiveHeavenEarth1991.pdf">2.4 million</a>, even though these studies used radiation risk estimates that are now dated and likely underestimated the <a href="http://press-files.anu.edu.au/downloads/press/n3873/pdf/ch08.pdf">risk</a>.</p> <p>The number of additional non-fatal cancer cases caused by test explosions is similar. As confirmed in a <a href="http://www.bioone.org/doi/full/10.1667/RR14608.1">large recent study</a> of nuclear industry workers in France, the UK and US, the numbers of radiation-related deaths due to other diseases, such as heart attacks and strokes, is also likely to be similar.</p> <p><strong>‘We all got crook’</strong></p> <p>Britain conducted 12 nuclear test explosions in Australia between 1952 and 1957, and hundreds of minor trials of radioactive and toxic materials for bomb development up to 1963. These caused untold health problems for local Aboriginal people who were at the highest risk of radiation. Many of them were not properly evacuated, and some were not informed at all.</p> <p>We may never know the full impact of these explosions because in many cases, as the Royal Commission report on British Nuclear Tests in Australia <a href="https://parlinfo.aph.gov.au/parlInfo/search/display/display.w3p;query=Id:%22publications/tabledpapers/HPP032016010928%22;src1=sm1">found in 1985</a>: “the resources allocated for Aboriginal welfare and safety were ludicrous, amounting to nothing more than a token gesture”. But we can listen to the survivors.</p> <p>The late Yami Lester directly experienced the impacts of nuclear weapons. A Yankunytjatjara elder from South Australia, Yami was a child when the British tested at Emu Field in October 1953. He <a href="https://icanw.org.au/wp-content/uploads/BlackMist-FINAL-Web.pdf">recalled</a> the “Black Mist” after the bomb blast:</p> <p><em>It wasn’t long after that a black smoke came through. A strange black smoke, it was shiny and oily. A few hours later we all got crook, every one of us. We were all vomiting; we had diarrhoea, skin rashes and sore eyes. I had really sore eyes. They were so sore I couldn’t open them for two or three weeks. Some of the older people, they died. They were too weak to survive all the sickness. The closest clinic was 400 miles away.</em></p> <p>His daughter, Karina Lester, is an ambassador for the International Campaign to Abolish Nuclear Weapons in Australia, and continues to be driven by her family’s experience. She <a href="https://icanw.org.au/choosinghumanity/">writes</a>:</p> <p><em>For decades now my family have campaigned and spoken up against the harms of nuclear weapons because of their firsthand experience of the British nuclear tests […] Many Aboriginal people suffered from the British nuclear tests that took place in the 1950s and 1960s and many are still suffering from the impacts today.</em></p> <p>More than 16,000 Australian workers were also exposed. A key <a href="https://www.dva.gov.au/documents-and-publications/british-nuclear-testing-australia-studies">government-funded study</a> belatedly followed these veterans over an 18-year period from 1982. Despite the difficulties of conducting a study decades later with incomplete data, it <a href="https://cpb-us-w2.wpmucdn.com/blogs.pace.edu/dist/0/195/files/2018/10/Australia-PosObs-Country-Report-7-1zbngsb.pdf">found</a> they had 23% higher rates of cancer and 18% more deaths from cancers than the general population.</p> <p>An additional health impact in Pacific island countries is the toxic disease “ciguatera”, caused by certain microscopic plankton at the base of the marine food chain, which thrive on damaged coral. Their toxins concentrate up the food chain, especially in fish, and cause illness and occasional deaths in people who eat them. In the Marshall Islands, Kiritimati and French Polynesia, outbreaks of the disease among locals have been associated with coral damage caused by <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(89)91212-9/fulltext">nuclear test explosions</a> and the extensive military and shipping infrastructure supporting them.</p> <p>Pacific survivors of nuclear testing haven’t been focused solely on addressing their own considerable needs for justice and care; they’ve been powerful advocates that no one should suffer as they have ever again, and have worked tirelessly for the eradication of nuclear weapons. It’s no surprise independent Pacific island nations are strong supporters of the new treaty, accounting for ten of the first 50 ratifications.</p> <p><strong>Negligence and little accountability</strong></p> <p>Some nations that have undertaken nuclear tests have provided some care and compensation for their nuclear test workers; only the US has made some <a href="https://www.justice.gov/civil/common/reca">provisions</a> for people exposed, though only for mainland US residents downwind of the Nevada Test Site. No testing nation has extended any such arrangement beyond its own shores to the colonised and minority peoples it put in harm’s way. Nor has any testing nation made fully publicly available its records of the history, conduct and effects of its nuclear tests on exposed populations and the environment.</p> <p>These nations have also been negligent by quickly abandoning former test sites. There has been inadequate clean-up and little or none of the long-term environmental monitoring needed to detect radioactive leakage from underground test sites into groundwater, soil and air. One example among many is the Runit concrete dome in the Marshall Islands, which holds nuclear waste from US testing in the 1940s and 50s. It’s increasingly <a href="https://www.latimes.com/projects/marshall-islands-nuclear-testing-sea-level-rise/">inundated by rising sea levels</a>, and is leaking radioactive material.</p> <p>The treaty provides a light in a dark time. It contains the only internationally agreed framework for all nations to verifiably eliminate nuclear weapons.</p> <p>It’s our fervent hope the treaty will mark the increasingly urgent beginning of the end of nuclear weapons. It is our determined expectation that our country will step up. Australia has not yet ratified the treaty, but the bitter legacy of nuclear testing across our country and region should spur us to join this new global effort.</p> <p><em>Written <a href="https://theconversation.com/profiles/tilman-ruff-89">Tilman Ruff</a>, University of Melbourne and <a href="https://theconversation.com/profiles/dimity-hawkins-292972">Dimity Hawkins</a>, Swinburne University of Technology.

Traditional skills help people on the tourism-deprived Pacific Islands survive the pandemic

<p>Tourism in the South Pacific has been <a href="https://theconversation.com/sun-sand-and-uncertainty-the-promise-and-peril-of-a-pacific-tourism-bubble-139661">hit hard by COVID-19</a> border closures with thousands of people out of work.</p> <p>Tourism normally provides one in four jobs in Vanuatu and one in three jobs in Cook Islands. It contributes <a href="https://pic.or.jp/ja/wp-content/uploads/2019/07/2018-Annual-Visitor-Arrivals-ReportF.pdf">between 20% and 70% of the GDP</a> of countries spanning from Samoa and Vanuatu to Fiji and Cook Islands.</p> <p>But our <a href="https://mro.massey.ac.nz/handle/10179/15742">research</a> shows how people are surviving – and in some cases, thriving – in the face of significant loss of income.</p> <p>This is due in part to their reliance on customary knowledge, systems and practices.</p> <p><strong>Islands impacted by border closures</strong></p> <p>The research involved an online survey completed by 106 people, along with interviews in six tourism-dependent locations across five countries.</p> <p>Research associates based in these countries did interviews in places such as villages next to resorts, or communities that regularly provided cultural tours for cruise ship passengers.</p> <p>They spoke with former and current tourism workers, community members and business owners who reflected on how they had adapted and what they hoped the future would hold.</p> <p>Almost 90% of survey respondents lived in households facing significant reductions in income. Owners of tourism-related businesses faced particular financial strain, with 85% of them saying they lost three-quarters or more of their usual income.</p> <p>But people showed considerable adaptive capacities and resilience in devising a range of strategies to meet their needs in the face of this dramatic loss of earnings.</p> <p>More than half the respondents were growing food for their families. Many were also fishing. People talked about using the natural abundance of the land and sea to provide food.</p> <p>One person from Rarotonga, part of the Cook Islands, said “no one is going hungry” and this was due to a number of factors:</p> <ol> <li>people had access to customary land on which to grow food</li> <li>traditional systems meant neighbours, clan members and church communities helped to provide for those who were more vulnerable</li> <li>there was still sufficient knowledge within communities to teach younger members who had lost jobs how to grow food and fish.</li> </ol> <p>One young man from Samoa, who had lost his job in a hotel, said:</p> <p><em>Like our family, everyone else has gone back to the land … I’ve had to relearn skills that have been not been used for years, skills in planting and especially in fishing … I am very happy with the plantation of mixed crops I have now and feeling confident we will be OK moving forward in these times of uncertainty.</em></p> <p><strong>Alternative livelihood options</strong></p> <p>People also engaged in a wide range of initiatives to earn cash, from selling products from their farms (fruit, root crops, other vegetables, cocoa, pigs and chickens) and the sea (a wide range of fish and shellfish) to starting small businesses.</p> <p>Examples included planting flowers to sell in bunches along the roadside, making doughnuts to take to the market, or offering sewing, yard maintenance or hair-cutting services.</p> <p>Goods and services were also <a href="https://www.theguardian.com/world/2020/may/08/two-piglets-for-a-kayak-fiji-returns-to-barter-system-as-covid-19-hits-economy">bartered</a>, rather than exchanged for cash.</p> <p>Sometimes social groups banded together to encourage one another in activities that earned an income. For example, a youth group near the resort island of Denarau, in Fiji, gained a contract to provide weekly catering for a rugby club.</p> <p><strong>When times are hard, it’s not all bad</strong></p> <p>Our study also examined four aspects of well-being: mental, financial, social and physical. Understandably, there was a clear decline in financial well-being. This was sometimes associated with greater stress and conflict within households.</p> <p>As one Cook Islands man said:</p> <p><em>There’s so many people in the house that we’re fighting over who’s going to pay for this, who’s going to pay for that.</em></p> <p>But the impacts on social, mental and physical well-being were mixed, with quite a number of people showing improvements.</p> <p><strong>How has COVID-19 impacted on the wellbeing of your family, household or community?</strong></p> <p>Many people were effusive in their responses when talking about how they now had more time with family, especially children. This was particularly the case for women who had previously worked long hours in the tourism sector. As one said:</p> <p><em>I feel staying (at home) during this pandemic has really helped a lot, especially with my kids. Now everything is in order. The spending of quality time with my family has been excellent and awesome.</em></p> <p>Others expressed satisfaction they had more time for meeting religious and cultural obligations. As one said, “everyone is more connected now”, and people had more time to look after others in the community:</p> <p><em>Extended family harmony has improved, particularly with checking welfare of others who may need help during this time.</em></p> <p>Business owners appreciated the chance to “rest and recharge”. As one Fijian business owner said:</p> <p><em>This break has given us a new breath of life. We have since analysed and pondered on what are the most important things in life apart from money. We have strengthened our relationships with friends and family, worked together, laughed and enjoyed each other’s company.</em></p> <p>These early research findings suggest customary systems are effectively supporting people’s resilience and well-being in the Pacific. A Pacific ethos of caring, respect, social and ecological custodianship and togetherness has softened the harsh blow of the COVID-19-induced economic slowdown.</p> <p><em>Written by <a href="https://theconversation.com/profiles/regina-scheyvens-650907">Regina Scheyvens</a>, Massey University and <a href="https://theconversation.com/profiles/apisalome-movono-1108178">Apisalome Movono</a>, Massey University.

Marine protected area is long overdue: Humans threaten the Antarctic Peninsula’s fragile ecosystem

<p>Antarctica, the world’s <a href="https://media.nature.com/original/magazine-assets/d41586-018-07183-6/d41586-018-07183-6.pdf">last true wilderness</a>, has been protected by an <a href="https://www.ats.aq/e/antarctictreaty.html">international treaty</a> for the last 60 years.

The impacts of climate change are especially insidious on the Western Antarctic Peninsula, one of the fastest-warming places on Earth.

There are 19 permanent and 30 seasonal research bases there.</p> <p>Another big threat to biodiversity in the peninsula is the commercial fishing of Antarctic krill, a small, shrimp-like crustacean which is the <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2017.2015">cornerstone of life</a> in this region.</p> <p><strong>A cornerstone of life</strong></p> <p>Krill is a foundation of the food chain in Antarctica, with whales, fish, squid, seals and Adélie and gentoo penguins all feeding on it.</p> <p>But as sea ice cover diminishes, more industrial fishing vessels can encroach on penguin, seal and whale foraging grounds, effectively acting as a competing super-predator for krill.</p> <p>In the past 30 years, colonies of Adélie and Chinstrap penguins on the Antarctic Peninsula have <a href="https://www.jstor.org/stable/41242231?seq=1">declined by more than 50%</a> due to reduced sea ice and krill harvesting.</p> <p>Commercial Antarctic krill fishing is largely for omega-3 dietary supplements and fish-meal.

Water on the Moon: research unveils its type and abundance

<p>The Moon was for a long time considered to be bone dry, with analyses of returned lunar samples from the Apollo missions showing only trace amounts of water. These traces were in fact believed to be due to contamination on Earth. But over the past two decades, re-analyses of lunar samples, observations by spacecraft missions, and theoretical modelling <a href="https://theconversation.com/digging-deep-in-search-of-water-on-the-moon-26775">have proved</a> this initial assessment to be wrong.</p> <p>“Water” has since been detected <a href="https://www.space.com/40481-moon-meteorite-mineral-hidden-lunar-water.html#:%7E:text=A%20mineral%20that%20requires%20the,moon%2C%20study%20team%20members%20said.">inside the minerals</a> in lunar rocks. Water ice has also been discovered to be mixed in with <a href="https://www.pnas.org/content/115/36/8907">lunar dust grains</a> in cold, permanently shadowed regions near the lunar poles.</p> <p>But scientists haven’t been sure how much of this water is present as “molecular water” – made up of two parts hydrogen and one part oxygen (H<sub>2</sub>O). Now two new studies published in Nature Astronomy <a href="https://www.nature.com/articles/s41550-020-01222-x">provide an answer</a>, while also giving an idea of how and where <a href="https://www.nature.com/articles/s41550-020-1198-9">to extract it</a>.</p> <p><strong>Water and more water</strong></p> <p>The term water isn’t just used for molecular water, but also also for detections of hydrogen (H) and <a href="https://www.britannica.com/science/hydroxyl-group">hydroxyl</a> (OH). Although H and OH could be combined by astronauts to form molecular water at the lunar surface, it is important to know in what form these compounds are present initially. That’s because this will have an impact on their stability and location under lunar surface conditions, and the effort required to extract them. Molecular water, if present as water ice, would be easier to extract than hydroxyl locked in rocks.</p> <p>The presence of water on the Moon is scientifically interesting; its distribution and form can help address some profound questions. For example, how did water and other volatile substances arrive at the inner Solar System in the first place? Was it produced there or <a href="https://www.nature.com/articles/ncomms11684#:%7E:text=We%20determine%20that%20a%20combination,the%20water%20in%20the%20Moon.">brought there by asteroids or meteorites</a>? Knowing more about the specific compound could help us find out.</p> <p>Understanding how much water is present, and its location, is also incredibly useful for planning human missions to the Moon and beyond. Water represents a key resource that can be used for life-support purposes – but it can also be split apart into its constituent elements and put to other uses. Oxygen could replenish air supplies, or be used in simple chemical reactions at the lunar surface to extract other useful resources from the regolith (soil composed of small grains). Water could also be used as rocket fuel in the form of liquid hydrogen and liquid oxygen.</p> <p>This means that the Moon has great potential to become a refuelling base for space missions further into the Solar System or beyond. Its lower gravity and lack of atmosphere means it would require less fuel to launch from there than from Earth. So when space agencies talk of <em>in-situ</em> <a href="https://theconversation.com/how-to-build-a-moon-base-120259">resource utilisation at the Moon</a>, water is front and centre of their plans, making the new papers extremely exciting.</p> <p><strong>New research</strong></p> <p>Instruments on board various spacecraft have previously measured “reflectance spectra” (light broken down by wavelength) from the Moon. These detect light coming from a surface to measure how much energy it reflects at a specific wavelength. This will differ based on what the surface consists of. Because it has water, the Moon’s surface <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6130389/">absorbs light at 3𝜇m wavelengths</a> (0.000003 metres). However, absorptions at this wavelength cannot distinguish between molecular water and hydroxyl compounds.</p> <p>Using the <a href="https://www.nasa.gov/mission_pages/SOFIA/overview/index.html">NASA/DLR Stratospheric Observatory for Infrared Astronomy (SOFIA)</a> telescope, flown at 43,000 feet, the team behind one of the new papers observed sunlit sections of the Moon’s surface in wavelengths of 5-8𝜇m. H<sub>2</sub>O results in a characteristic peak in the spectrum at 6𝜇m, and by comparing a near-equatorial area as a baseline (thought to have almost no water) with an area near the south pole, this study reports the first unequivocal observations of molecular water under ambient conditions at the lunar surface at an abundance of 100-400 parts per million.</p> <p>This is several orders of magnitude too large for most of the water to be adsorbed onto regolith grain surfaces. Instead, the authors suggest that the water they have observed must be locked up inside glass formed by tiny meteorites impacting and melting already hydrated regolith grains. Alternatively, it could be present in voids between grain boundaries, which would make it easier to extract. Where exactly this water is sited would be of extreme interest for future explorers as it would dictate the processes and energy required to extract it.</p> <p>Luckily, the other paper used new theoretical models, based on temperature data and higher resolution images from the Lunar Reconnaissance Orbiter, to refine predictions of where conditions are right for molecular water to be trapped as ice.</p> <p>Previous research has shown already that there are such kilometres-wide “cold traps” in permanently shadowed areas <a href="https://science.sciencemag.org/content/281/5382/1496.full">near the poles</a>, where water ice may be present. Evidence from orbiting spacecraft, however, was inconclusive about this being molecular water or hydroxyl. The new study finds that there are also abundant small cold traps where conditions permit water ice to accumulate – on the scale of centimetres or decimetres. In fact, such traps should be hundreds to thousands of times more numerous than larger cold traps.</p> <p>The team calculates that 0.1% of the total lunar surface is cold enough to trap water as ice, and that the majority of these icy cold traps are at high latitudes (&gt; 80°). This is particularly near to the lunar south pole, narrowing down the choice of future landing sites with the highest chance of finding trapped water ice. However, it is important to realise that the two studies investigated areas at different latitudes (55°-75°S vs &gt;80°S) and therefore cannot be compared directly.</p> <p>Nevertheless, these latest discoveries further enhance our understanding of the history of water on our nearest neighbour. They will undoubtedly strengthen plans for a return to the Moon. Instruments such as the European Space Agency’s (<a href="https://exploration.esa.int/web/moon/-/59102-about-prospect">PROSPECT payload on Luna 27</a>) will be able to make measurements on the Moon to “ground-truth” these tantalising glimpses of the wealth of information yet to be discovered.</p> <p><em>Written by <a href="https://theconversation.com/profiles/james-mortimer-125966">James Mortimer</a>, The Open University and <a href="https://theconversation.com/profiles/mahesh-anand-125967">Mahesh Anand</a>, The Open University.

Australia expresses ‘serious concerns’ about invasive searches of women at Doha airport

<p>The Australian government has registered “serious concerns” with Qatar about an incident in which female passengers, including Australians, were taken off a flight bound for Australia and subjected to an invasive search.</p> <p>The incident happened at Hamad international airport in Doha earlier this month after a fetus was discovered in an airport bathroom.</p> <p>The story was broken by the Seven Network, which reported that “women at the airport, including thirteen Australians, were removed from flights, detained and forced to undergo an inspection in an ambulance on the tarmac.”</p> <p>According to the report, Qatari authorities forced the women to remove their underwear.</p> <p>A foreign affairs spokesperson said on Sunday: “The Australian government is aware of concerning reports regarding the treatment of female passengers, including Australian citizens, at Doha (Hamad) airport in Qatar.</p> <p>"We have formally registered our serious concerns regarding the incident with Qatari authorities and have been assured that detailed and transparent information on the event will be provided soon.”</p> <p>The matter is being handled by Foreign Minister Marise Payne.</p> <p><em>Written by <a href="https://theconversation.com/profiles/michelle-grattan-20316">Michelle Grattan</a>, University of Canberra.

Mammoth task: the Russian family on a resurrection quest to tackle the climate crisis

<p>On the banks of the River Kolyma, deep into the Arctic circle in north-east Siberia, lies a gently rusting Soviet-era tank. It doesn’t look out of place here. After all, just down the river is the hull of a half-sunken ship and the remains of an Aeroflot aeroplane fuselage that met an unfortunate end.</p> <p>The tank isn’t working at the moment – it’s hard to find parts – but until recently, it was driven by a bearded Russian wearing a beret, a cigarette clamped permanently between his jaws, taking a sort of macabre delight in destroying trees and churning up soil.</p> <p>This is Sergey Zimov who, together with his son Nikita, is carrying out an experiment on this scrubby patch of Arctic tundra: they want to restore the prehistoric “mammoth steppe” ecosystem and see if it proves their hypothesis that a grassland grazed by large herbivores has an effect on slowing down – or even reversing – the thawing permafrost.</p> <p>Currently the landscape is mostly larch forest with very low biodiversity. There are no animals, save for the odd moose and millions of mosquitoes. Meanwhile, Arctic temperatures are increasing <a href="https://www.npr.org/2014/12/18/371438087/arctic-is-warming-twice-as-fast-as-world-average">twice as quickly</a> as those in the rest of the planet, and the permafrost that covers 65% of Russia <a href="https://www.nature.com/articles/s41558-019-0592-8?fbclid=IwAR1GLrQiGpH_25nIjqH_ih4zp24YpbtvhF2nec3bUK8e9Hi8zYaD151Irws">is thawing</a>. Fast. Many of the buildings in the town of Chersky – where the Zimov experiment is based – sport deep cracks (some have collapsed altogether), roads are buckled and the ground is humped and hollowed.</p> <p>The clue to what counts as permafrost is in the name – permanently frozen ground. As with anything frozen, it is liable to thaw if temperatures get too hot. That is precisely what is happening all across the Arctic.</p> <p>Permafrost is difficult to define. It covers almost a quarter of the Northern Hemisphere and sequesters <a href="https://arctic.noaa.gov/Report-Card/Report-Card-2019/ArtMID/7916/ArticleID/844/Permafrost-and-the-Global-Carbon-Cycle">double</a> the carbon found in the atmosphere today. When frozen, the microbes that feed on the organic material found in permafrost are “asleep”. When it thaws, they wake up and the anaerobic respiration produced releases greenhouse gases.</p> <p>Officially, it’s soil that has been frozen for two years or more, with an “active layer” that thaws seasonally. But thanks to global warming, permafrost has been thawing with increasing magnitude, with all sorts of disruptive effects. A process called a “<a href="https://epic.awi.de/id/eprint/31461/">thermokarst megaslump</a>” has opened up huge holes across the tundra and the bodies of mammoths are being found with <a href="https://www.nytimes.com/2019/08/04/world/europe/russia-siberia-yakutia-permafrost-global-warming.html">greater frequency</a>, their flesh decomposing in the Arctic sun. Strange things are awakening. A couple of years ago, a team of Russian scientists reportedly found <a href="https://www.smithsonianmag.com/smart-news/ancient-roundworms-allegedly-resurrected-russian-permafrost-180969782/">30,000-year-old worms</a> in the permafrost which, upon being warmed up gently in a Moscow laboratory, began to wriggle around.</p> <p>Almost ironically, the mammoths exposed by the thawing of permafrost are what sparked Sergey Zimov’s hypothesis: that large herbivores are necessary to maintain the integrity of permafrost. The Zimovs use their tank to mimic the tread and destructiveness of the woolly mammoth in a 144km² fenced off area they call “<a href="https://pleistocenepark.ru/">Pleistocene Park</a>”.</p> <p>Recreating the mammoth’s former ecosystem might seem like an impossible task given the creature has been extinct for 4,000 years, but for the Zimovs this is a minor detail. They are concerned with ecological processes – the web of connection that produces a functioning ecosystem. The tank will do just fine as a mammoth-stand in, destroying trees and stimulating grass growth in its wake.</p> <p>There are animals in the park that play a similar role. Yakutian horses and reindeer have been purchased from local indigenous herders, and other creatures that haven’t lived in the region for a long time (yak, sheep, Kalmykian cow, musk ox, bison) have come from much further afield. There are around 120 animals in total, although deaths and births happen with regularity. Last summer, Nikita Zimov undertook a perilous journey by truck to transport 12 baby bison all the way from Denmark. The roads are dreadful for most of Northern Siberia, and then they disappear completely. Travelling by barge along the Kolyma is the only way in.</p> <p>A few seasons before that, an expedition to Wrangel Island in the Arctic Ocean to find musk oxen almost ended in disaster after their boat hit a storm. The discovery on return that all the oxen were males was a particularly frustrating one. The animals in the park roam where they please, encouraged to breed and forage so their behaviours <a href="https://www.journals.uchicago.edu/doi/abs/10.1086/285824">have an effect</a> on the permafrost: trampling compacts ground and keeps it frozen, while grassland reflects solar radiation.</p> <p>Even though the tank remains out of commission, the Zimovs are hoping that soon they won’t need it at all. They’re hoping that one day a mammoth will return to the Arctic.</p> <p><strong>Resurrecting the dead</strong></p> <p>Sometime in the early 2000s, rumblings began in the scientific community of a new form of conservation that would potentially fix a growing problem. What if, instead of fighting what seemed to be an <a href="https://www.theguardian.com/environment/2017/jul/10/earths-sixth-mass-extinction-event-already-underway-scientists-warn">increasingly losing battle</a> against extinction, you could potentially resurrect an extinct creature through cloning methods?</p> <p>Still reeling from the implications of Dolly the sheep in 1997, in 2003 a team of scientists in Zaragoza, Spain, managed to <a href="https://www.theatlantic.com/technology/archive/2013/03/the-10-minutes-when-scientists-brought-a-species-back-from-extinction/274118/">successfully produce</a> a clone of the extinct Pyrenean ibex, having previously collected genetic material from the last remaining individual of the species. Although the cloned calf only lived for ten minutes, the genie was out of the bottle: extinction didn’t have to be forever.</p> <p>Advances in genetic technology saw the arrival of CRISPR, a type of gene editing software that allowed for swift and cheap splicing of genomes. Now it didn’t matter if you didn’t have a viable cell for cloning – you could simply create a complete genome in a laboratory. This is what happened with <a href="https://reviverestore.org/projects/woolly-mammoth/progress/">the mammoth</a>, whose genome was sequenced in 2015, becoming the first extinct creature to be catalogued.</p> <p>While preserved mammoth bodies are common finds in Siberia, their flesh prevented from decomposition by permafrost, living cells begin to degrade at the point of death so a certain amount of cell degradation is inevitable. But by using CRISPR, a scientist is able to plug, say, the genome of an Asian elephant with the genes that make the physical traits of a mammoth (cold adapted blood, thick hair, small ears). Theoretically, if that genome was implanted into an egg and then fertilised, the Asian elephant in question would give birth to a mammoth, albeit one that is genetically a hybrid.</p> <p>De-extincting the mammoth in the future is a possibility, but the follow up question must surely be: what does one do with such a creature? Enter the Pleistocene Park. The vast expanse of tundra and cold temperatures, not to mention the ready-made connotations with a similar de-extinction “project”, Jurassic Park, mean it is the obvious place for any newly “resurrected” (hybridised, to be exact) mammoth to go.</p> <p>All this talk of restoration, rebirth and resurrection raises further questions: one of them being the ethical implications of “playing God”. But the other, larger question regards the role of humanity on the planet. We are now <a href="https://www.nature.com/articles/d41586-019-01641-5">unofficially</a> living in the Anthropocene – a new epoch that designates humans as top geological agents, leaving our mark in the rock and influencing just about every planetary process. Most of our actions are not positive ones, evidenced by the tide of environmental destruction, global warming and explosive levels of extinction left in our wake.</p> <p>Would resurrecting the mammoth be a way for humans to right past wrongs, or would it be an extension of the power and control we wield over a ravaged planet?</p> <p><strong>‘We are as gods’</strong></p> <p>I visited the Pleistocene Park in the summer of 2018 to attempt to answer this question. The mammoth is a bit of a thorny conversation topic to the Zimovs. Yes, Sergey Zimov strides around the tundra wearing a t-shirt sporting a stylised cartoon of the massive hairy elephant, but his son is quick to shoot me down when I ask about their level of involvement in de-extinction.</p> <p>“You have a lot of people believing in God,” he says. “And they don’t like this mammoth return. So I try and use it to bring attention to the park, but I don’t want any of the criticism!” But the relationship between de-extinction scientists and the park is difficult to ignore. A few weeks after I leave the park, the Zimovs are visited by the geneticist <a href="https://wyss.harvard.edu/team/core-faculty/george-church/">George Church</a>, probably the biggest proponent of mammoth de-extinction, and <a href="http://sb.longnow.org/SB_homepage/Home.html">Stewart Brand</a>, lifelong environmentalist and now supporter of what is termed a “good Anthropocene” (the idea that humans should use their power to benevolently steward the planet). “We are as gods,” Brand <a href="https://www.edge.org/conversation/stewart_brand-we-are-as-gods-and-have-to-get-good-at-it#:%7E:text=Stewart%20Brand%20Talks%20About%20His%20Ecopragmatist%20Manifesto&amp;text=Forty%20years%20ago%2C%20I%20could,to%20get%20good%20at%20it">famously quipped</a>: “And we have to get good at it.”</p> <p>I’m sceptical of this viewpoint. The Anthropocene concept is a <a href="https://theconversation.com/anthropocene-doesnt-exist-and-species-of-the-future-will-not-recognise-it-111762">flattening one</a>: it categorises all humans as the same, separated from nature, wreaking havoc on a lifeless Earth. It distributes blame equally, rather than directed towards the worst polluters. It ignores the uneven and ongoing effects of climate change on different parts of the globe. Planetary stewardship – no matter how benevolent – reinforces this idea. It suggests things can, and should, be controlled.</p> <p>But I don’t see much evidence of this control during my time at the park. The first day I’m taken there (it’s a 30 minute boat ride away from the science station that houses visitors) Nikita Zimov is informed by his rangers that the herd of musk oxen hasn’t been seen for days so he heads into the undergrowth to find the animals. I’m left alone, surrounded by flooded plains, no animals to be seen save for a blind yak.</p> <p>A few days later, the permafrost tunnel floods. A sort of underground laboratory dug to house permafrost cores, scientific equipment and frozen fish, it was supposedly placed at a high enough level that the annual floodwaters of the Kolyma would never reach the entrance - until they did. We spend a day pumping the water out and dislodging the items that had stuck fast to the frozen ceiling. A little way down the river, the expensive scientific equipment owned by a well-funded contingent of German permafrost scientists is submerged under water.</p> <p>Meanwhile, the Zimovs are furious about the 12 baby bison they have purchased from an Alaskan herder, still stuck in their pen. They’re unable to find a pilot willing to fly them over in the creaky, old DC-4 plane they have found. Everything that seemingly can go wrong, does go wrong. The Pleistocene Park is showing encouraging signs of becoming a grassland ecosystem, and <a href="https://www.nature.com/articles/s41598-020-60938-y?sf232308455=1">initial tests</a> show the permafrost is thawing less within the park’s boundaries.</p> <p>But on the summer solstice (a swelteringly hot June day in the Arctic) we take a drill and some thaw depth probes to do some readings outside of the park, and the prognosis for the permafrost is not good. “We are fighting global warming,” Nikita Zimov says. “But global warming is fighting back.”</p> <p><strong>Tusk hunts</strong></p> <p>When permafrost makes the news, it’s never good. In early June, a fuel tank at the Norilsk power plant in Siberia <a href="https://www.bbc.co.uk/news/world-europe-52977740">collapsed</a> because of thawing permafrost and 17,500 tonnes of diesel spilled into the river. A lot of people live and work on top of permafrost in Russia, and at the time of the Soviet Union, thousands of people were lured to the Arctic on the promise of highly paid jobs and cheap houses as part of a plan to “master the North”. Now the Soviet Union is long gone, along with all the perks, and thawing permafrost is making Arctic life very difficult.</p> <p>A sort of black-market industry has emerged, with groups of men heading out onto the tundra for months at a time to look for mammoth bodies that thawing permafrost has exposed. <a href="https://www.nationalgeographic.com/magazine/2013/04/tracking-mammoths1/">They’re after the tusks</a> that can be sold for a hefty profit to China, by far the world’s top market for ivory goods. These tusk hunts are often dangerous, with the men using illegal high-powered water cannons to blast holes and tunnels in permafrost, hundreds of miles away from towns or hospitals. Those who find a tusk have struck white gold, but those that don’t (most of them) will lose money.</p> <p>There’s another tension too. To many Siberian indigenous groups, the mammoth is a sacred beast and mustn’t be disturbed – to do so could mean death. Tusk hunters face an often-agonising decision: to betray their belief system or to feed their family.</p> <p>I became aware of an uneasy relationship between tusk hunters and scientists when I visited the Mammoth Museum in Yakutsk, where I spent the winter in 2018. Yakutsk is the world’s coldest and largest city built on permafrost, and it has no roads in or out – in the summer you take the plane, in the winter the frozen rivers become ice roads and a thriving trucking network ferries supplies to and from the Arctic towns.</p> <p>The Mammoth Museum and the Melnikov Permafrost Institute are institutions dedicated to understanding permafrost and tundra flora and fauna. This includes the mammoth. Since the collapse of the Soviet Union, the funding for these institutions has dried up. The scientists at the permafrost institute can only wait for international researchers with big grants to show up.</p> <p>The museum has struck up an awkward partnership with a biotechnology company in Seoul, South Korea. Sooam Biotech is known for <a href="https://www.vanityfair.com/style/2018/08/dog-cloning-animal-sooam-hwang">cloning pets</a> (most famously, Barbara Streisand’s dog) and has made no secret of its desire to clone a mammoth. The Mammoth Museum is informed of any mammoth finds by tusk hunters and Sooam Biotech is offered first dibs on collecting genetic material from the body. In exchange, Sooam Biotech has financed a state-of-the-art laboratory and equipment for the museum.</p> <p>Meanwhile, the Yakutian government has recently passed <a href="https://phys.org/news/2018-12-siberian-region-permafrost-planet.html">a law that protects permafrost</a>, enshrining the rights of Yakuts to live on top of solid ground. This law is mostly symbolic. Permafrost thaw is a result of global warming, yet it is Arctic Siberia that bears the brunt.</p> <p>These smaller, messier permafrost interactions say something important. The Pleistocene Park and the designs of scientists wanting to resurrect the mammoth work very much within a global narrative. The <a href="https://www.kickstarter.com/projects/907484977/pleistocene-park-an-ice-age-ecosystem-to-save-the">promotional material</a> for the park involve references to “the world’s best plan” and “saving the world”. Similarly to the way the Anthropocene concept flattens humanity, constructing the Earth on a purely global scale produces a potential future catastrophe that hasn’t happened yet. Think about any Hollywood disaster movie – we must do something to prevent it.</p> <p>Curating apocalypse in this way means the more local catastrophic events become seen as harbingers of a threat to come, rather than catastrophes in their own right. Permafrost makes the news as a “<a href="https://eos.org/articles/the-ticking-time-bomb-of-arctic-permafrost#:%7E:text=An%20Arctic%20ecosystem%20is%20in,than%20a%20decade%20to%20recover.">ticking time bomb</a>”, something that will blow up unless we do something about it. Yet the people who live in the Arctic, particularly indigenous groups and fragile communities like Chersky, are already dealing with an apocalypse and have been for some time.</p> <p>The unpredictability of permafrost – now very much impermanent – challenges those proponents of a good Anthropocene who believe we can control the planet.</p> <p><strong>Putting life on ice</strong></p> <p>Freezing, being frozen, staying frozen – they all suggest a period of stasis, of suspension. Permafrost itself indicates permanence, but that can no longer be said to be true. What to do, when the planet is warming and the Arctic is warming even faster? Build freezers, that’s what.</p> <p>Cryobanks have emerged in the past decade, often attached to museums, as a response to the rapid rise in species extinction. They offer a way to put “life on ice”, stored safely away until something can be done, be that captive breeding or de-extinction. Many of these projects have eschatological overtones – the <a href="https://www.smh.com.au/technology/the-lazarus-project-scientists-quest-for-deextinction-20150417-1mng6g.html">Lazarus Project</a>, <a href="https://www.frozenark.org/">The Frozen Ark</a> – and suggest that control can somehow be regained by turning the temperature down.</p> <p>The 42,000-year-old horse lying in Yakutsk’s Mammoth Museum is dead. I can smell it. Its body had been found a few months earlier in a permafrost bank, and had been frozen in the museum’s freezer ever since. The horse has been so well preserved, it looks like it’s merely sleeping. A delegation from the pet cloning company Sooam Biotech is visiting Yakutsk to take samples, and I’ve been invited along to view the autopsy.</p> <p>The head of the delegation, and CEO of the company, is Hwang Woo-Suk – a once disgraced South Korean veterinary scientist who made <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1892198/">headlines in 2005</a> when he claimed he had cloned human cells. He hadn’t, and went from the pride of South Korea to a laughing stock overnight while claiming he had been deceived by a former colleague in the process. A few years later he began showing up in Yakutsk looking for mammoths and other prehistoric creatures. His pet cloning company makes him rich, but cloning a mammoth would bring global fame again.</p> <p>The Anthropocene may be the time of the human, but really it is the time of certain humans, or certain actions. Actions have consequences. The warming of the Arctic and the thawing of permafrost is but one of these consequences. The reaction to this, to attempt to regain control of planetary processes, whether this be through resurrecting the mammoth or restoring its habitat, is indicative of a commitment to a good Anthropocene that aims to continue human dominance on the Earth.</p> <p>Having lived on top of permafrost, felt my feet sink into the mushy ground and rolled a ball of it between my fingers like putty, I remain doubtful any of this will work. What impact the Pleistocene Park may have on the permafrost around it is negated thousands of miles away by yet another thermokarst megaslump or another Arctic wildfire. While Nikita Zimov is philosophical about this, saying “it’s better to walk rather than to sit and wait for death”, it’s difficult to imagine the park ever reaching a point where it can mitigate permafrost thaw across the world. The mammoth, should it ever be resurrected, would surely exist as a curio rather than a thriving species, a monument to the hubris of playing God.</p> <p>Those advocating a good Anthropocene mean well, but a much deeper state change is needed. The continuous layer of permafrost in Arctic Siberia is showing signs of <a href="https://www.nationalgeographic.co.uk/environment/2018/08/exclusive-some-arctic-ground-no-longer-freezing-even-winter">becoming discontinuous</a> through thaw. Discontinuity, I think, must also be our path. We need to halt and refuse the destructive practices that have underpinned the last century and beyond if there’s to be any hope of doing better in the future.</p> <p>Discontinuity isn’t just a state of being, it is also a state of mind. The warming of the Arctic and the thawing of permafrost are huge concerns, yes, but attempts to force control of an increasingly out of control situation might well produce terrible gods rather than benevolent ones. Resurrecting mammoths – playing god – speaks to a doubling down of the mastery implied by the Anthropocene moniker.</p> <p>Discontinuity, conversely, allows for the creativity in thinking of futures that relinquish destructive human dominance. The Pleistocene Park may be one of these futures, or it may not be. The point is, by becoming discontinuous, we become attuned to a radical openness that allows for thinking differently – ethically, collectively, progressively – about our role as humans on a discontinuous Earth.</p> <p><em>Written by Charlotte Wrigley.

Remote-work visas will shape the future of work, travel and citizenship

<p>During lockdown, travel was not only a distant dream, it was unlawful. Some even <a href="https://theconversation.com/coronavirus-is-a-once-in-a-lifetime-chance-to-reshape-how-we-travel-134764">predicted</a> that how we travel would change forever. Those in power that broke travel bans <a href="https://theconversation.com/could-the-dominic-cummings-affair-damage-boris-johnson-in-the-long-term-heres-what-history-tells-us-139514">caused scandals</a>. The empty skies and <a href="https://theconversation.com/coronavirus-should-give-us-hope-that-we-are-able-to-tackle-the-climate-crisis-133174">hopes</a> that climate change could be tackled were a silver lining, of sorts. COVID-19 has certainly made travel morally divisive.</p> <p>Amid these anxieties, many countries eased lockdown restrictions at the <a href="https://www.bbc.co.uk/news/business-532061480">exact time</a> the summer holiday season traditionally began. Many avoided flying, opting for staycations, and in mid-August 2020, global flights were <a href="https://www.statista.com/statistics/1104036/novel-coronavirus-weekly-flights-change-airlines-region/">down 47%</a> on the previous year. Even so, hundreds of thousands still holidayed abroad, only then to be caught out by sudden quarantine measures.</p> <p>In mid-August for example, <a href="https://www.bbc.co.uk/news/uk-politics-53773914">160,000 British holiday makers</a> were still in France when quarantine measures were imposed. On August 22, Croatia, Austria, and Trinidad and Tobago were added to the UK’s <a href="https://www.bbc.co.uk/news/uk-53871078">quarantine list</a>, then Switzerland, Jamaica and the Czech Republic <a href="https://www.bbc.co.uk/news/uk-53937997">the week after</a> – causing continued confusion and panic.</p> <p>This insistence on travelling abroad, with ensuing rushes to race home, has prompted much <a href="https://www.washingtonpost.com/world/europe/europe-travel-coronavirus/2020/08/20/a426b6e4-e23e-11ea-82d8-5e55d47e90ca_story.html">tut-tutting</a>. Some have predicted travel and tourism may cause winter lockdowns. Flight shaming is already a <a href="https://theconversation.com/flight-shaming-how-to-spread-the-campaign-that-made-swedes-give-up-flying-for-good-133842">cultural sport</a> in Sweden, and vacation shaming has even become <a href="https://www.washingtonpost.com/world/europe/europe-travel-coronavirus/2020/08/20/a426b6e4-e23e-11ea-82d8-5e55d47e90ca_story.html">a thing</a> in the US.</p> <p>Amid these moral panics, Barbados has reframed the conversation about travel by launching a “<a href="https://www.barbadoswelcomestamp.bb/">Barbados Welcome Stamp</a>” which allows visitors to stay and work remotely for up to 12 months.</p> <p>Prime Minister Mia Mottley explained the new visa has been prompted by COVID-19 making short-term visits difficult due to time-consuming testing and the potential for quarantine. But this isn’t a problem if you can visit for a few months and work through quarantine with the beach on your doorstep. This trend is rapidly spreading to other countries. <a href="https://forms.gov.bm/work-from-bermuda/">Bermuda</a>, <a href="https://e-resident.gov.ee/nomadvisa/">Estonia</a> and <a href="https://stopcov.ge/en/News/Article/Gov't_to_allow_int'l_citizens_to_work_remotely_from_Georgia">Georgia</a> have all launched remote work-friendly visas.</p> <p>I think these moves by smaller nations may change how we work and holiday forever. It could also change how many think about citizenship.</p> <p><strong>Digital nomads</strong></p> <p>This new take on visas and border controls may seem novel, but the idea of working remotely in paradise is not new. <a href="https://theconversation.com/digital-nomads-what-its-really-like-to-work-while-travelling-the-world-99345">Digital nomads</a> - often millennials engaged in mobile-friendly jobs such as e-commerce, copywriting and design - have been working in exotic destinations for the last decade. The <a href="https://www.telegraph.co.uk/news/features/11597145/Living-and-working-in-paradise-the-rise-of-the-digital-nomad.html">mainstream press</a> started covering them in the mid-2010s.</p> <p>Fascinated by this, I started <a href="https://link.springer.com/article/10.1007/s40558-020-00172-4">researching</a> the digital nomad lifestyle five years ago – and haven’t stopped. In 2015, digital nomads were seen as a niche but rising trend. Then COVID-19 paused the <a href="https://medium.com/age-of-awareness/has-covid-19-ruined-the-digital-nomad-ecf6772afda2">dream</a>. Digital nomad Marcus Dace was working in Bali when COVID-19 struck. His travel insurance was invalidated, and he’s now in a flat near Bristol wondering when he can travel.</p> <p>Dace’s story is common. He told me: “At least 50% of the nomads I knew returned to their home countries because of <a href="https://www.cdc.gov/">CDC</a> and <a href="https://www.gov.uk/government/organisations/foreign-commonwealth-office">Foreign Office</a> guidance.” Now this new burst of visa and border policy announcements has pulled digital nomads back into the <a href="https://www.thetimes.co.uk/article/how-to-be-a-digital-nomad-and-work-remotely-while-travelling-the-world-vn09rd7j6">headlines</a>.</p> <p>So, will the lines between digital nomads and remote workers <a href="https://theconversation.com/five-workplace-trends-will-shape-life-after-lockdown-138077">blur?</a> COVID-19 might still be making international travel difficult. But remote work – the other foundation of digital nomadism – is now firmly in the mainstream. So much so that remote work is considered by many to be <a href="https://theconversation.com/remote-working-the-new-normal-for-many-but-it-comes-with-hidden-risks-new-research-133989">here to stay</a>.</p> <p>Before COVID-19, office workers were geographically tethered to their offices, and it was mainly business travellers and the lucky few digital nomads who were able to take their work with them and travel while working. Since the start of the pandemic, many digital nomads had to work in a single location, and office workers have become remote workers – giving them a glimpse of the digital nomad lifestyle.</p> <p>COVID-19 has upended other old certainties. Before the pandemic, digital nomads would tell me that they <a href="https://link.springer.com/article/10.1007/s40558-020-00172-4">despised</a> being thought of as tourists. This is perhaps unsurprising: tourism was viewed as an escape from work. And other established norms have toppled: homes became offices, <a href="https://theconversation.com/after-coronavirus-how-seasonal-migration-and-empty-centres-might-change-our-cities-139439">city centres emptied</a>, and workers looked to <a href="https://www.rightmove.co.uk/press-centre/village-enquiries-double-as-city-dwellers-escape-to-the-country/">escape to the country</a>.</p> <p>Given this rate of change, it’s not such a leap of faith to accept tourist locations as remote work destinations.</p> <p><strong>A Japanese businessman predicted this</strong></p> <p>The idea of tourist destinations touting themselves as workplaces is not new. Japanese technologist <a href="https://ethw.org/Tsugio_Makimoto">Tsugio Makimoto</a> <a href="https://www.wiley.com/en-us/Digital+Nomad-p-9780471974994">predicted</a> the digital nomad phenomenon in 1997, decades before millennials Instagrammed themselves working remotely in Bali. He prophesied that the rise of remote working would force nation states “to compete for citizens”, and that digital nomadism would prompt “declines in materialism and nationalism”.</p> <p>Before COVID-19 – with populism and nationalism <a href="https://theconversation.com/the-new-right-how-a-frenchman-born-150-years-ago-inspired-the-extreme-nationalism-behind-brexit-and-donald-trump-117277">on the rise</a> – Makimoto’s prophecy seemed outlandish. Yet COVID-19 has turned <a href="https://theconversation.com/overtourism-a-growing-global-problem-100029">over-tourism</a> into under-tourism. And with a growing list of countries launching schemes, it seems nations are starting to “compete” for remote workers as well as tourists.</p> <p>The latest development is the Croatian government discussing a <a href="https://www.total-croatia-news.com/lifestyle/45869-croatian-bureaucracy-2-0">digital-nomad visa</a> – further upping the stakes. The effects of these changes are hard to predict. Will local businesses benefit more from long-term visitors than from hordes of cruise ship visitors swarming in for a day? Or will an influx of remote workers create Airbnb hotspots, <a href="https://qz.com/quartzy/1574182/ahead-of-its-ipo-what-even-is-airbnb-anymore/">pricing locals out</a> of popular destinations?</p> <p><strong>It’s down to employers</strong></p> <p>The real question is whether employers allow workers to switch country. It sounds far-fetched, but Google staff can already work remote until <a href="https://www.forbes.com/sites/jackkelly/2020/08/21/salesforce-joins-google-and-facebook-in-extending-work-from-home-to-next-summer/">summer 2021</a>. Twitter and 17 other companies have <a href="https://www.entrepreneur.com/article/354872">announced</a> employees can work remotely indefinitely.</p> <p>I’ve interviewed European workers in the UK during COVID-19 and some have been allowed to work remotely from home countries to be near family. At Microsoft’s <a href="https://www.microsoft.com/en-us/research/event/new-future-of-work/">The New Future of Work</a> conference, it was clear that most major companies were mobilising task forces and would launch <a href="https://theconversation.com/remote-working-is-here-to-stay-but-that-doesnt-mean-the-end-of-offices-or-city-centres-145414">new flexible working policies</a> in autumn 2020.</p> <p>Countries like Barbados will surely be watching closely to see which companies could be the first to launch employment contracts allowing workers to move countries. If this happens, the unspoken <a href="https://en.wikipedia.org/wiki/Social_contract#:%7E:text=The%20theory%20of%20an%20implicit,legitimacy%20to%20such%20a%20government">social contract</a> between employers and employees - that workers must stay in the same country – will be broken. Instead of booking a vacation, you might be soon booking a workcation.</p> <p><em>Written by Dave Cook.

<div class="post_body_wrapper"> <div class="post_body"> <div class="body_text "> <p>Travel agent Valeria Belardi was anxious as she prepared for her seven-day Mediterranean cruise in a world where COVID-19 is rampant.</p> <p>She was one of 3,000 pioneering cruise passengers onboard the MSC Grandiosa, which is the first cruise liner to return to the Mediterranean after the shutdown of the cruising industry.</p> <p>The voyage was a different experience, as there was constant COVID-19 testing, social distancing, hand sanitising and temperature checks, but according to Belardi, it was "relaxing and enjoyable".</p> <p>While MSC Cruises wouldn't confirm exact numbers, the Grandiosa was operating at about 60 per cent of its 6,300 passenger capacity.</p> <p>Belardi on board the cruise liner enjoyed pre-packaged snacks, swims in the pool and trips to the spa.</p> <p>"I think cruises could be the safest holiday, right now," said Belardi to <a rel="noopener" href="https://edition.cnn.com/travel/article/future-of-cruising-coronavirus/index.html" target="_blank" class="_e75a791d-denali-editor-page-rtflink"><em>CNN</em></a><em>.</em></p> <p>Before boarding, passengers are tested for COVID-19 via a primary antigen test and a secondary molecular test.</p> <p>MSC Cruises representative Luca Biondolillo told CNN that one embarking passenger tested positive at both stages.</p> <p>"In accordance with the protocol, the passenger, as well as his travelling party, were denied boarding," said Biondolillo.</p> <p>"Additionally, other passengers who had reached the ship with the same van were denied boarding as they were close contacts of the one passenger who tested positive."</p> <p>The cruise involved day trips, with sightseeing in Malta and the Sicilian city of Palermo.</p> <p>However, the trips and excursions are pre-planned and tightly controlled. One family broke the rules during a port stop, who were denied reboarding the ship.</p> <p>"The health and safety protocols are put in place for the benefit of every single person," Biondolillo said. "There can be no breaking of the rules.</p> <p>"These people risked jeopardizing everybody else's holidays and health."</p> <p>Cruise operators are desperate to figure out a solution to travelling that keeps people safe.</p> <p>"We know that for every 1% drop in cruising that occurs worldwide, up to 9,100 jobs can be lost," Bari Golin-Blaugrund, a spokeswoman for industry body Cruise Lines International Association, told CNN.</p> <p>Golin-Blaugrund says CLIA is confident that cruising will recover as demand is already being seen for 2021 vacations and beyond, but, she says, with most cruise operations still suspended, that means up to 2,500 jobs being lost per day.</p> <p>"By the end of September, the worldwide impact will be $77 billion, 518,000 jobs and $23 billion in wages lost."</p> <p>Cruise lines are now finding themselves with excess ships, with Carnival Corporation announcing plans to remove at least six cruise ships from its fleet. The company has since posted a $4.4 billion loss for the second quarter of 2020.</p> <p>Meanwhile, Holland America also announced plans to offload four of its 14 ships: Amsterdam, Maasdam, Rotterdam and Veendam.</p> <p>"It's always difficult to see any ship leave the fleet, especially those that have a long and storied history with our company," said Stein Kruse, chief executive officer of Holland America Group and Carnival UK, in a <a rel="noopener" href="https://www.hollandamerica.com/blog/topics/news/four-ships-to-leave-the-holland-america-line-fleet-in-2020/" target="_blank" class="_e75a791d-denali-editor-page-rtflink">statement.</a></p> <p>Former crew members are not eager to return to cruise liners without it returning to normal either.</p> <p>Austrian dancer Conny Seidler has been keeping an eye on the cruise industry, but she's not sure about the new regulations.</p> <p>"I understand all the precautions and everything -- there is a reason behind it. But for me, it takes away all the reasons why people would go and work on the ship," Seidler tells CNN. </p> <p>"Because you would go on a ship because you want to travel the world, you want to see places."</p> <p>"People from poorer countries come to the ship to earn money and send it back home," she adds. </p> <p>"But what keeps those people sane, if you never go out, is you go to the gym or you go and socialize with your friends in the crew bar, these kind of things and that's all kind of been taken away."</p> </div> </div> </div>

How COVID-19 could impact travel for years to come

<p>In late 2019, <a href="https://www.iata.org/en/about/">the International Air Transport Association (IATA)</a> published its <a href="https://www.iata.org/contentassets/36695cd211574052b3820044111b56de/airline-industry-economic-performance-dec19-report.pdf">“Economic Performance of the Airline Industry</a>” report. It contained a 2020 forecast of 4.1 per cent growth in global air traffic demand and net post-tax profits for North American airlines of US$16.5 billion.</p> <p><a href="https://www2.deloitte.com/content/dam/Deloitte/us/Documents/consumer-business/us-consumer-2019-us-travel-and-hospitality-outlook.pdf">Travel industry consulting firms</a> predicted the continuing pattern of travel growth across all of the major components of travel including hotels, cruises and surface travel as well as air. The forecast for travel was sunny, with few clouds on the horizon.</p> <p>Fast forward to the summer of 2020, and the IATA is forecasting the worst financial performance in the history of commercial aviation, <a href="https://www.iata.org/en/pressroom/speeches/2020-06-24-01/">predicting a global loss of US$84 billion</a>. And the aerospace industry supporting airlines with equipment parts and services pronounced that 2020 is <a href="https://www.bbc.com/news/business-52468882">the gravest crisis the industry has ever known.</a></p> <p><strong>Permanent changes?</strong></p> <p>Let’s review the lessons being learned by the travel industry during the COVID-19 pandemic and how travel might be different as the world deals with the aftermath.</p> <p>Travel has evolved significantly in the past six months since the spread of the COVID-19 pandemic. There will likely <a href="https://www.chicagobusiness.com/opinion/virus-will-make-everything-you-hate-about-flying-worse">be a number of current initiatives in passenger and facility hygiene and sanitation</a> that will stay in place post-pandemic.</p> <p>The woes of cruise ship operators, in the meantime, will continue as travellers continue to remain wary of travel in confined spaces.</p> <p>Public health officials have identified <a href="https://www.gov.uk/guidance/coronavirus-covid-19-safer-aviation-guidance-for-operators#social-distancing">three societal practices that are key to controlling the spread of COVID-19</a>, each of which have an impact on the allure of travel — social distancing of two metres, frequent and intense hand-washing to reduce the risk of hand-borne transmission of the virus to the face, and face coverings in confined spaces.</p> <p>While it’s generally accepted that the minimum social distancing cannot be maintained while travelling in today’s commercial aircraft, some carriers — <a href="https://www.citynews1130.com/2020/07/03/air-canada-physical-distancing-flight/">though not all, including Air Canada</a> — have adopted <a href="https://news.delta.com/delta-blocking-middle-seats-pausing-automatic-advance-upgrades-and-more-enable-more-space-safer">a policy of leaving an open seat beside a passenger</a>.</p> <p><strong>Empty middle seats</strong></p> <p>This initiative has attracted the attention of both public health officials as well air transport executives and associations, resulting in <a href="https://www.businessinsider.com/jeff-merkley-to-propose-bill-blocking-middle-seats-on-planes-2020-7">an attempts by an American legislator to regulate empty middle seats on flights</a>. Airline executives have predicted a <a href="https://www.foxnews.com/travel/ryanair-ceo-middle-seats-idiotic-airline-fly">dire financial impact</a> from this attempt to ease crowding on airliners.</p> <p>Quarantines are also being used by authorities to mitigate the spread of COVID-19 from travellers arriving from jurisdictions that have a higher level of virus cases.</p> <p>These quarantines range <a href="https://www.newsweek.com/do-you-have-quarantine-after-flying-california-1518697">from in-country travel bans among states or provinces</a> to <a href="https://www.thesun.co.uk/travel/12233400/spain-quarantine-travel-ban-france-germany-holidays/">national quarantines for travellers arriving from high-risk regions</a>.

The debate between <a href="https://winnipeg.citynews.ca/2020/05/04/taking-temperatures-to-screen-for-covid-19/">public health officials and airline executives will undoubtedly remain tense</a> as the world continues to grapple with the first wave, and in some places a second wave, of COVID-19 outbreaks.</p> <p><strong>‘Travel bubbles’</strong></p> <p>A growing number of countries have allowed the travel industry to <a href="https://www.gov.uk/guidance/coronavirus-covid-19-travel-corridors#countries-and-territories-with-no-self-isolation-on-arrival-in-england">promote “travel bubbles” and “corona corridors” as first steps</a> to jumpstart air travel and tourism.

Coronavirus risks in public bathrooms: What goes into the toilet doesn’t always stay there

<p>Most public restrooms are grungy in the best of times. Now, we have the coronavirus risk to contend with, too. There are lots of risks – dirty sinks and door handles, airborne particles and other people in small, enclosed spaces who may or may not be breathing out the coronavirus.</p> <p>So, how do you stay safe when you’re away from home and you’ve really got to go?</p> <p>As a medical doctor and epidemiologist, I study infectious diseases involving the gastrointestinal tract. Here are four things to pay attention to when it comes to any public restroom.</p> <p><strong>What goes into the toilet doesn’t always stay there</strong></p> <p>Have you ever thought about what happens when you flush a toilet?</p> <p>Scientists who worry about disease transmission in hospitals have, and their findings are worth remembering when you’re in a public restroom.</p> <p>All that bubbling, swirling and splashing <a href="https://doi.org/10.1080/02786826.2013.814911">can aerosolize fecal waste</a>, sending tiny particles airborne. A <a href="https://doi.org/10.1186/s13756-018-0301-9">study on hospital bathrooms</a> found that the amount of those particles spiked after a toilet was flushed, and the concentration in the air remained high 30 minutes later. It didn’t matter if the test was done right next to the toilet or 3 feet away. Second and third flushes continued to spread particles. Another study, published June 16, simulated toilet plumes from flushing and also found that <a href="https://doi.org/10.1063/5.0013318">a large number of particles rose above the toilet seat</a> and lingered in the air. The scientists’ advice: close the lid before flushing.</p> <p>Researchers have found that the new coronavirus, <a href="https://doi.org/10.1016/S2468-1253(20)30083-2">SARS-CoV-2, can be shed in feces for up to a month</a> after the illness. That’s longer than in respiratory samples, though how much of that time the virus could be causing infections and whether the virus has infected humans through fecal waste <a href="https://www.cdc.gov/coronavirus/2019-ncov/faq.html">isn’t yet known</a>.</p> <p><strong>Surfaces can harbor the virus, so wash up</strong></p> <p>The aerosols generated when <a href="https://doi.org/10.1073/pnas.2006874117">someone infected with coronavirus coughs or even talks</a> can be inhaled, of course, but they also settle out on surrounding surfaces, such as bathroom counter tops.</p> <p>To stay safe, be extra careful and touch as little as possible in public restrooms, including door handles. Whatever you do, <a href="https://www.nytimes.com/2020/03/02/well/live/coronavirus-spread-transmission-face-touching-hands.html">don’t touch your eyes, nose or mouth</a> after touching these surfaces – your mucous membranes are the coronavirus’s entryway into your body.</p> <p>When you’re done, <a href="https://theconversation.com/why-hand-washing-really-is-as-important-as-doctors-say-132840">thoroughly wash your hands with soap and water</a>, and maybe <a href="http://doi.org/10.1111/jam.13014">skip the hot-air hand dryer</a>, which can also create aerosols and blow them toward you.</p> <p>Carrying face masks, hand sanitizer and disinfectant wipes with you can help you be prepared, particularly if the facilities lack soap or running water.</p> <p><strong>Enclosed spaces are a problem</strong></p> <p>The air in an enclosed space like a public restroom can have <a href="https://doi.org/10.1016/S2213-2600(20)30245-9">coronavirus particles in it for several hours</a> after someone infectious with COVID-19 was there.</p> <p>Scientists still don’t know how <a href="https://theconversation.com/what-we-do-and-do-not-know-about-covid-19s-infectious-dose-and-viral-load-135991">much of the virus you have to take in</a> to become infected, but it’s better to be safe than sorry. Limiting the amount of time spent in any enclosed indoor space – restrooms and <a href="https://theconversation.com/how-to-lower-your-coronavirus-risk-while-eating-out-restaurant-advice-from-an-infectious-disease-expert-138925">restaurants</a> included – can reduce the potential for getting sick from the coronavirus.</p> <p><strong>Wear a mask, and walk out if others aren’t</strong></p> <p>One of the more insidious characteristics of the new coronavirus is that someone infected with the virus can be spreading it <a href="https://www.nap.edu/read/25774/chapter/1#3">two to three days before they show any symptoms</a>. Some people don’t show symptoms at all, but they can still be infectious for days.</p> <p>Based on surveillance during the Princess cruise ship outbreak in Yokohama, Japan, <a href="http://doi.org/10.2807/1560-7917.ES.2020.25.10.2000180">15 to 20% of the people tested positive</a> for the coronavirus had no symptoms. <a href="http://doi.org/10.1001/jamanetworkopen.2020.10182">Data from Wuhan, China</a>, put the number of asymptomatic cases at closer to 40%.</p> <p>Keeping <a href="https://doi.org/10.1093/infdis/jiaa189">at least 6 feet away from others</a> and wearing a <a href="https://doi.org/10.1038/s41591-020-0843-2">mask can help you avoid spreading the coronavirus</a> if you’re asymptomatic and don’t realize it. They can also help protect you, though social distancing in small public restrooms isn’t always possible.</p> <p>If someone else is in the restroom without a mask on, the best advice is to walk out. It isn’t worth the risk.</p> <p><em>Written by William Petri.

Antarctica without windchill and the Louvre without queues: How to travel the world from home

<p>SpaceX’s recent <a href="https://theconversation.com/spacexs-historic-launch-gives-australias-booming-space-industry-more-room-to-fly-139760">Falcon 9 rocket launch</a> proves humanity has come leaps and bounds in its effort to reach other worlds. But now there’s a quicker, safer and environmentally friendlier way to travel to the centre of the galaxy – and you can do it too.</p> <p><a href="https://chandra.harvard.edu/photo/2020/gcenter/">NASA</a> has co-developed a free virtual reality (VR) adventure providing 500 years of travel around the black hole at the centre of the Milky Way. The experience is available to download from two major VR stores, <a href="https://store.steampowered.com/app/1240350/Galactic_Center_VR/">Steam</a> and <a href="https://www.viveport.com/21f8b24c-783b-4af2-8e81-a63a14553721">Viewport</a>, in a non-collapsed star system near you.</p> <p>And this kind of spacefaring may be the tip of the iceberg when it comes to the potential of virtual travel and tourism.</p> <p><strong>The virtual travel bug</strong></p> <p>Simply speaking, VR refers to technology that immerses users in a computer-generated world that removes them from reality. Augmented Reality (AR), however, aims to superimpose virtual imagery over a user’s view of the real world. Pokémon Go is a popular AR game.</p> <p>VR-based tourism has a longer history than you might think. In the 1850s, it involved staring at <a href="https://www.loc.gov/pictures/collection/stereo/background.html">stereographs</a> with a <a href="https://www.smithsonianmag.com/innovation/sterographs-original-virtual-reality-180964771/">stereoscope</a>. With this invention, viewers looked at slightly different images through each eye, which were then assembled by the brain to make a new image providing the illusion of spatial depth (in other words, a 3D effect).</p> <p>A century later, 1950s <a href="https://en.wikipedia.org/wiki/Cinerama">Cinerama</a> widescreen viewing inspired cinematic travel though its large, curved screens and multiple cameras.</p> <p>The 1960s <a href="https://www.engadget.com/2014-02-16-morton-heiligs-sensorama-simulator.html">Sensorama</a> foretold a shiny future of multimodal immersive cinematic experiences, playing 3D films with sound, scents and wind to immerse users. In <a href="https://www.vrs.org.uk/virtual-reality/history.html">VR circles</a>, Ivan Sutherland became famous for inventing the head-mounted display, as well as augmented reality (AR).</p> <p>Travel restrictions under COVID-19 <a href="https://www.ft.com/virtualtravel">present an opportunity</a> for virtual reality travel to finally take off.</p> <p>In an era of lockdowns and social distancing, we could use VR to travel to remote, distant or even no longer existing places. Remote tourism is here (the <a href="https://www.remote-tourism.com/">Faroe Islands</a> offers a great example), and interest in VR tourism is <a href="https://www.forbes.com/sites/solrogers/2020/03/18/virtual-reality-and-tourism-whats-already-happening-is-it-the-future/#5b39a26228a6">blossoming</a>.</p> <p><strong>VR comes in many forms</strong></p> <p>The word “virtual” can refer to an immersive 3D experience, but also 360° panorama photographs and movies (a <a href="https://wiki.panotools.org/Panorama_formats">cylinder, sphere or cube of photographs</a>).</p> <p>What is deemed “virtual” varies greatly across different devices and platforms. Let’s look at some of the ways this term is applied.</p> <p><strong>Desktop virtual environments</strong>: these are computer-based 3D environments on a flat screen, without the spatial immersion of VR platforms.</p> <p><strong>Cinematic VR</strong>: these are phone-based panoramic environments. Many desktop experiences of 360° movies or images can be conveyed in low-cost <a href="https://arvr.google.com/cardboard/">stereoscopic VR through smartphones</a>. Google Street view can be viewed in <a href="https://www.blog.google/products/google-vr/get-closer-look-street-view-google-earth-vr/">Google VR</a> on Android and <a href="https://3g.co.uk/guides/what-smartphones-work-with-virtual-reality">some Apple</a> smartphones, but it’s not real VR.</p> <p><strong>Head-mounted displays</strong>: HMDs such as <a href="https://www.instructables.com/id/How-to-make-Google-Cardboard/">Google Cardboard</a> and <a href="https://arvr.google.com/daydream/smartphonevr/">Google Daydream</a> are what many people think of when they hear “virtual reality”. Some HMDs are self-contained, not requiring connection to a computer or console. Arguably, the market is <a href="https://3dinsider.com/oculus-vs-htc-vive-vs-psvr/">dominated</a> by the Oculus range owned by Facebook, the HTC Vive range, and PlayStation VR.</p> <p><strong>VR in a pandemic</strong></p> <p>In a post-coronavirus age, device sharing is problematic. HMDs aren’t easy to clean and VR software can quickly become obsolete, with new headsets sometimes not running two-year-old software. Users also have to deal with costly updates, eyestrain, and having to share displays that sat on someone else’s face.</p> <p>Developing and sharing content across different devices can be a nightmare but there are increasingly <a href="https://www.vrtourviewer.com/">simple</a> and effective ways to create <a href="https://www.pocket-lint.com/ar-vr/news/google/142054-google-arcore-android-s-equivalent-to-apple-arkit-explained">AR</a> and VR content, despite a bewildering range of platforms and equipment (there are more than <a href="https://www.archives.gov/files/applied-research/ncsa/8-an-overview-of-3d-data-content-file-formats-and-viewers.pdf">140 3D file formats</a>).</p> <p>Despite this, many VR projects are not preserved – including <a href="https://www.mdpi.com/2071-1050/11/8/2425">virtual heritage</a> projects!

Climate explained: does your driving speed make any difference to your car’s emissions?

<p><strong><em>Does reducing speed reduce emissions from the average car?</em></strong></p> <p>Every car has an optimal speed range that results in minimum fuel consumption, but this range differs between vehicle types, design and age.</p> <p>Typically it looks like this graph below: fuel consumption rises from about 80km/h, partly because air resistance increases.</p> <p>But speed is only one factor. No matter what car you are driving, you can reduce fuel consumption (and therefore emissions) by driving more smoothly.</p> <p>This includes anticipating corners and avoiding sudden braking, taking the foot off the accelerator just before reaching the peak of a hill and cruising over it, and removing roof racks or bull bars and heavier items from inside when they are not needed to make the car lighter and more streamlined.</p> <p><strong>Driving wisely</strong></p> <p>In New Zealand, <a href="https://www.aa.co.nz/about/newsroom/media-releases/events/aa-energywise-rally-starts-with-a-rush/">EnergyWise rallies</a> used to be run over a 1200km course around the North Island. They were designed to demonstrate how much fuel could be saved through good driving habits.</p> <p>The competing drivers had to reach each destination within a certain time period. Cruising too slowly at 60-70km/h on straight roads in a 100km/h zone just to save fuel was not an option (also because driving too slowly on open roads can contribute to accidents).</p> <p>The optimum average speed (for both professional and average drivers) was typically around 80km/h. The key to saving fuel was driving smoothly.</p> <p>In the first rally in 2002, the Massey University entry was a brand new diesel-fuelled Volkswagen Golf (kindly loaned by VW NZ), running on 100% biodiesel made from waste animal fat (as Z Energy has been <a href="https://www.newsroom.co.nz/2018/05/02/106691/biofuels-z-energys-tortuous-carbon-solution">producing</a>).</p> <p>A car running on fossil diesel emits about 2.7kg of carbon dioxide per litre and a petrol car produces 2.3kg per litre. Using biofuels to displace diesel or petrol can reduce emissions by up to 90% per kilometre if the biofuel is made from animal fat from a meat works. The amount varies depending on the source of the biofuel (sugarcane, wheat, oilseed rape). And of course it would be unacceptable if biofuel crops were replacing food crops or forests.</p> <p>Regardless of the car, drivers can reduce fuel consumption by 15-20% by improving driving habits alone – reducing emissions and saving money at the same time.</p> <p><strong>Fuel efficiency</strong></p> <p>When you are thinking of replacing your car, taking into account fuel efficiency is another important way to save on fuel costs and reduce emissions.</p> <p>Many countries, including the US, Japan, China and nations within the European Union, have had fuel efficiency standards for more than a decade. This has driven car manufacturers to design ever <a href="http://www.climatechangeauthority.gov.au/files/files/Light%20Vehicle%20Report/CCA_TransportReport_Appendices.WEB.pdf">more fuel-efficient vehicles</a>.</p> <p>Most light-duty vehicles sold globally are subject to these standards. But Australia and New Zealand have both dragged the chain in this regard, partly because most vehicles are imported.</p> <p>New Zealand also remains hesitant about introducing a “<a href="https://www.consumer.org.nz/articles/government-announces-consultation-light-vehicle-fleet-feebate">feebate</a>” scheme, which proposes a fee on imported high-emission cars to make imported hybrids, electric cars and other efficient vehicles cheaper with a subsidy.</p> <p>In New Zealand, driving an <a href="https://theconversation.com/climate-explained-why-switching-to-electric-transport-makes-sense-even-if-electricity-is-not-fully-renewable-136502">electric car results in low emissions</a> because electricity generation is 85% renewable. In Australia, which still relies on coal-fired power, electric cars are responsible for higher emissions unless they are recharged through a local renewable electricity supply.</p> <p>Fuel and electricity prices will inevitably rise. But whether we drive a petrol or electric car, we can all shield ourselves from some of those future price rises by driving more efficiently and less speedily.</p> <p><em>Written by Ralph Sims.

Sun, sand and uncertainty: The promise and peril of a Pacific tourism bubble

<p>Pacific nations have largely <a href="https://www.nzherald.co.nz/world/news/article.cfm?c_id=2&amp;objectid=12328702">avoided</a> the worst health effects of COVID-19, but its economic impact has been devastating. With the tourism tap turned off, unemployment has soared while GDP has plummeted.</p> <p>In recent weeks, Fiji Airways laid off 775 employees and souvenir business Jack’s of Fiji laid off 500. In Vanuatu 70% of tourism workers have lost their jobs. Cook Islands is estimated to have experienced a <a href="https://www.newsroom.co.nz/2020/05/18/1177034/an-island-in-debt">60% drop in GDP</a> in the past three months.</p> <p>In response, many are calling for the Pacific to be included in the proposed <a href="https://www.stuff.co.nz/national/politics/121727144/coronavirus-transtasman-travel-bubble-date-down-to-australians-winston-peters-says">trans-Tasman travel corridor</a>. Such calls have come from <a href="https://devpolicy.org/vanuatu-a-tourism-sector-perspective-on-potential-recovery-from-covid-19-and-tc-harold-20200506-1/">tourism operators</a>, <a href="https://www.rnz.co.nz/international/pacific-news/418156/pressure-mounts-on-nz-and-aust-to-include-pacific-in-bubble">politicians</a> and at least one <a href="https://www.newsroom.co.nz/ideasroom/2020/05/28/1205479/nz-pacific-islands-bubble-should-come-first">health expert</a>.</p> <p>Quarantine concerns aside, there is economic logic to this. Australians and New Zealanders make up <a href="http://pacific.scoop.co.nz/2019/06/tourism-sector-achieves-3-16-million-visitor-arrivals-in-18/">more than 50%</a> of travellers to the region. Some countries are massively dependent: two-thirds of visitors to Fiji and three-quarters of visitors to Cook Islands are Aussies and Kiwis.</p> <p>Cook Islands has budgeted NZ$140 million for economic recovery, but this will increase the tiny nation’s debt. Prime Minister Henry Puna has <a href="https://www.newshub.co.nz/home/travel/2020/06/cook-islands-prime-minister-calls-for-pacific-bubble-as-soon-as-new-zealand-enters-covid-19-alert-level-1.html">argued for</a> a limited tourism bubble as soon as New Zealand relaxes its COVID-19 restrictions to alert level 1. Cook Islands News editor Jonathan Milne <a href="https://player.whooshkaa.com/coronavirus-nz?episode=665993">estimates</a> 75-80% of the population is “desperate to get the tourists back”.</p> <p>A Pacific bubble would undoubtedly help economic recovery. But this merely highlights how <a href="https://www.eco-business.com/opinion/impact-of-covid-19-on-tourism-in-small-island-developing-states/">vulnerable</a> these island economies have become. Tourism <a href="https://www.researchgate.net/publication/337854342_Development_and_change_Reflections_on_tourism_in_the_South_Pacific">accounts</a> for between 10% and 70% of GDP and up to one in four jobs across the South Pacific.</p> <p>The pressure to reopen borders is understandable. But we argue that a tourism bubble cannot be looked at in isolation. It should be part of a broader strategy to diversify economies and enhance linkages (e.g. between agriculture and tourism, to put more local food on restaurant menus), especially in those countries that are most perilously dependent on tourism.</p> <p><strong>Over-dependence on tourism is a trap</strong></p> <p>Pacific nations such as Vanuatu and Fiji have recovered quickly from past crises such as the GFC, cyclones and coups because of the continuity of tourism. COVID-19 has turned that upside down.</p> <p>People are coping in the short term by reviving subsistence farming, fishing and <a href="https://www.theguardian.com/world/2020/may/08/two-piglets-for-a-kayak-fiji-returns-to-barter-system-as-covid-19-hits-economy">bartering</a> for goods and services. Many are still suffering, however, due to limited state welfare systems.</p> <p>In Fiji’s case, the government has taken the drastic step of allowing laid-off or temporarily unemployed workers to withdraw from their superannuation savings in the National Provident Fund. Retirement funds have also been used to <a href="https://www.fijivillage.com/news/We-need-Fiji-Airways-to-come-back-strongly-for-the-future-of-the-country---Koroi-48r5xf/">lend FJ$53.6 million</a> to the struggling national carrier, Fiji Airways.</p> <p>Fiji has taken on more debt to cope. Its debt-to-GDP ratio, which ideally should sit below 40% for developing economies, has risen from 48.9% before the pandemic to 60.9%. It’s likely to <a href="http://www.economy.gov.fj/images/Budget/budgetdocuments/supplements/SUPPLEMENT-TO-THE-COVID-19-RESPONSE-BUDGET-ADDRESS.pdf">increase further</a>.</p> <p>High debt, lack of economic diversity and dependence on tourism put the Fijian economy in a very vulnerable position. Recovery will take a long time, probably requiring assistance from the country’s main trading partners. In the meantime, Fiji is pinning hopes on joining a New Zealand-Australia <a href="https://www.rnz.co.nz/international/pacific-news/416392/fiji-keen-to-join-nz-australia-travel-bubble">travel bubble</a>.</p> <p><strong>Out of crisis comes opportunity</strong></p> <p>Supporting Pacific states to recover is an opportunity for New Zealand and Australia to put their respective Pacific <a href="https://www.mfat.govt.nz/en/about-us/mfat-annual-reports/mfat-annual-report-2018-19/case-study-the-pacific-reset-a-year-on/">Reset</a> and <a href="https://www.dfat.gov.au/geo/pacific/Pages/the-pacific">Step-Up</a> policies into practice. If building more reciprocal, equitable relationships with Pacific states is the goal, now is the time to ensure economic recovery also strengthens their socio-economic, environmental and political infrastructures.</p> <p>Economic well-being within the Pacific region is already closely linked to New Zealand and Australia through seasonal workers in horticulture and viticulture, remittance payments, trade and travel. But for many years there has been a major trade imbalance in favour of New Zealand and Australia. Shifting that balance beyond the recovery phase will involve facilitating long-term resilience and sustainable development in the region.</p> <p>A good place to start would be the recent United Nations Economic and Social Commission for Asia and the Pacific <a href="https://www.unescap.org/sites/default/files/Policy%20brief_MPFD_Combating%20COVID-19%20in%20Asia%20and%20the%20Pacific%20updated.pdf">report</a> on recovering from COVID-19. Its recommendations include such measures as implementing social protection programs, integrating climate action into plans to revive economies, and encouraging more socially and environmentally responsible businesses.</p> <p>This is about more than altruism – enlightened self-interest should also drive the New Zealand and Australian agenda. Any longer-term economic downturn in the South Pacific, due in part to over-reliance on tourism, could lead to instability in the region. There is a clear <a href="https://www.weforum.org/agenda/2018/11/the-next-economic-crisis-could-cause-a-global-conflict-heres-why">link</a> between serious economic crises and social unrest.</p> <p>At a broader level, the pandemic is already <a href="https://asia.nikkei.com/Politics/International-relations/Coronavirus-gives-China-an-edge-as-it-expands-sway-in-the-Pacific">entrenching</a> Chinese regional influence: loans from China make up 62% of Tonga’s total foreign borrowing; for Vanuatu the figure is 43%; for Samoa 39%.</p> <p>China is taking the initiative through what some call “<a href="https://devpolicy.org/chinas-coronavirus-covid-19-diplomacy-in-the-pacific-20200527-1/">COVID-19 diplomacy</a>”. This involves funding pandemic stimulus packages and offering aid and investment throughout the Pacific, including drafting a <a href="https://www.fbcnews.com.fj/news/free-trade-agreement-talks-underway-between-fiji-and-china/">free trade agreement</a> with Fiji.</p> <p>That is not to say Chinese investment in Pacific economies won’t do good. Rather, it is an argument for thinking beyond the immediate benefits of a travel bubble. By realigning their development priorities, Australia and New Zealand can help the Pacific build a better, more sustainable future.</p> <p><em>Written by Regina Scheyvens and Apisalome Movono.

Climate change is the most important mission for universities of the 21st century

<p>Universities are confronting the possibility of <a href="https://melbourne-cshe.unimelb.edu.au/__data/assets/pdf_file/0009/3392469/Australian-Universities-COVID-19-Financial-Management.pdf">profound sector-wide transformation</a> due to the continuing effects of COVID-19. It is prompting much needed debate about what such transformation should look like and what kind of system is in the public interest.</p> <p>This is now an urgent conversation. If universities want a say in what the future of higher education will look like, they will need to generate ideas quickly and in a way that attracts wide public support.</p> <p>This will involve articulating their unique role as embedded, future-regarding, ethical generators of crucial knowledge and skills, well-equipped to handle coming contingencies and helping others do the same.</p> <p>And this means higher education changes are entangled with another major force for transformation – climate change.</p> <p>How can universities credibly claim to be preparing young people for their futures, or to be working with employers, if they do not take into account the kind of world they are helping to bring about?</p> <p><strong>A vital role in a climate changed world</strong></p> <p>Whether indexed by the continual climb in <a href="https://www.scientificamerican.com/article/heat-and-humidity-are-already-reaching-the-limits-of-human-tolerance/">extreme heat and humidity</a>, the <a href="http://nsidc.org/arcticseaicenews/">melting of Arctic ice</a>, the eruption of <a href="https://www.science.org.au/news-and-events/news-and-media-releases/australian-bushfires-why-they-are-unprecedented">unprecedented mega-fire events</a> or the <a href="https://www.un.org/sustainabledevelopment/blog/2019/05/nature-decline-unprecedented-report/">rapid degradation of ecosystems</a> and <a href="https://www.pnas.org/content/early/2020/05/26/2008198117">disruption of human settlements</a>, climate change is here.</p> <p>It is rapidly exacerbating environmental and social stress across the globe, as well as directly and indirectly impacting all institutions and areas of life. And worse still, global greenhouse gas concentrations are moving in exactly the opposite direction to what we need, with <a href="https://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy.html">carbon emissions growing by 2.0% in 2019, the fastest growth for seven years</a>.</p> <p>Much-needed transitions towards low carbon and well-adapted systems are emerging. But they are too piecemeal and slow relative to what is needed to avoid large scale <a href="https://www.deepsouthchallenge.co.nz/projects/climate-change-cascade-effect">cascading</a> and <a href="https://www.climatecouncil.org.au/resources/compound-costs-how-climate-change-damages-australias-economy/">compounding impacts to our planet</a>.</p> <p>Universities, along with all other parts of our society, will feel the effects of climate change. The cost of the devastation at the Australian National University due to the summer’s fires and hailstorm, for instance, is estimated to <a href="https://www.abc.net.au/news/2020-05-27/coronavirus-hail-bushfires-cause-225m-loss-at-anu/12290522">be A$75 million dollars</a>.</p> <p>Failure to appropriately adapt to the increasing likelihood of such events <a href="https://www.nature.com/articles/s41558-020-0715-2">threatens to undermine research of all sorts</a>.</p> <p>Whether due to climate impacts (such as <a href="https://www.mprnews.org/story/2018/09/06/npr-coastal-labs-studying-increased-flooding-consider-moving-due-to-increased-floodin">the effects of sea level rise on coastal laboratories</a>) or policy and market shifts away from carbon-intensive activities (such as coal powered energy), research investments face the risk of becoming <a href="https://theconversation.com/why-stranded-assets-matter-and-should-not-be-dismissed-51939">stranded assets</a>. Not only could expensive infrastructure and equipment be rendered redundant, but certain skills, capabilities and projects could too.</p> <p>Universities are key to enabling Australian society to transition to a safer and lower emissions pathway. They are needed to provide the knowledge, skills and technologies for this positive transition. And they are also needed to <a href="https://climateoutreach.org/system-change-vs-behaviour-change-is-a-false-choice-covid-19-shows-how-theyre-connected/">foster the social dialogue and build the broad public mandate</a> to get there.</p> <p>This means old ideas of universities as isolated and values-free zones, and newer notions of them as cheap consultants to the private sector, fundamentally fail to fulfil the role universities now need to play.</p> <p>They must become public good, mission-driven organisations devoted to rapidly progressing human understanding and action on the largest threat there has ever been, to what they are taken to represent and advance – human civilisation.</p> <p><strong>Universities must become more sustainable…</strong></p> <p>Inaction will erode the trust on which universities rely, especially among the key constituencies universities are meant to serve – young people and the private, community and public sectors.</p> <p><a href="https://globalclimatestrike.net/">Students</a>, <a href="https://www.asyousow.org/report/clean200-2019-q1">businesses</a>, <a href="https://en.unesco.org/events/climate-change-and-ngos-eight-international-forum-ngos-official-partnership-unesco">not-for-profit organisations</a> and certain <a href="https://www.nationalgeographic.com/environment/2019/09/climate-change-report-card-co2-emissions/">governments</a> are already acting far more forcefully than universities, even as the latter claim to be intellectual leaders.</p> <p>Who universities invest in, fund, partner with and teach, and how, will increasingly be judged through a climate change lens.

It called for the sector to reduce emissions and invest in climate change research, teaching and outreach. Even more have signed the <a href="https://www.sdgaccord.org/climateletter">SDG (sustainable development goals) Accord’s climate emergency declaration</a>, which calls for:</p> <ul> <li>mobilising more resources for action-oriented climate change research and skills creation</li> <li>committing to going carbon neutral by 2030 or 2050 at the very latest</li> <li>increasing the delivery of environmental and sustainability education across curriculum, campus and community outreach programs.</li> </ul> <p>Some universities are already starting to build aspects of climate change into their operations. Most prominent have been efforts to divest university finances from direct support of fossil fuels. While some institutions are still dragging their feet, the University of California has announced it will <a href="https://www.latimes.com/california/story/2020-05-19/uc-fossil-fuel-divest-climate-change">fully divest </a> its US$126 billion endowment from fossil fuels.</p> <p>Pressure is similarly growing for <a href="https://unisuperdivest.org/">Unisuper to stop investing</a> Australian university staff superannuation into corporations that endanger the very future staff are saving for.</p> <p>University campuses are being refigured as sites of energy production and consumption. <a href="https://www.strathmore.edu/serc/">Strathmore University in Kenya </a>and <a href="https://www.rmit.edu.au/news/all-news/2019/nov/rmit-leads-the-way-on-renewable-energy">RMIT University in Australia</a> are among those who produce their own renewable energy.</p> <p>Although <a href="https://theconversation.com/australias-universities-are-not-walking-the-talk-on-going-low-carbon-72411">few universities are working towards absolute reductions in emissions</a>, or have appropriate climate adaptation plans, initiatives such as the <a href="https://www.timeshighereducation.com/student/best-universities/top-universities-climate-action">Times Higher Education Impact Index</a> are increasing interest in visible climate action.</p> <p><strong>… and they must change teaching and research</strong></p> <p>Teaching and research too must change. University students can <a href="https://study.curtin.edu.au/offering/course-pg-masters-of-environment-and-climate-emergency--mc-envclm/">choose programs and optional modules dedicated to climate change</a>. But this isn’t enough. Climate change has to be integrated in all disciplines.</p> <p>It is essential universities do not quarantine climate change as some kind of specialist topic. A <a href="https://journals.aom.org/doi/full/10.5465/amp.2018.0183.summary">recent analysis of management studies</a> found a profound lack of engagement across the discipline with the implications of climate change.</p> <p>As Cornell University’s Professor of Engineering Anthony Ingraffea argues, when it comes to educating the future generation, <a href="https://www.enr.com/articles/48389-a-call-to-action-for-engineers-on-climate-change">“doing the right thing on climate change should be baked into an engineer’s DNA”</a>.</p> <p>This means recognising the strong overlap between work that has instrumental value for climate change action and work that celebrates the intrinsic value of human understanding. The intellectual and social challenges presented by climate change are perhaps the greatest justification yet for why we need open-minded, open-ended exploration and dialogue of the sort universities can provide.</p> <p>Universities produce the knowledge galvanising others to act. It is time for them to act too. It is time for all of us who work in or with universities to reappraise our institutions in light of the changes needed, the changes coming, and the changes already here.</p> <p>This is the public mission of universities in the 21st century. And it is the most pressing mission there is.</p> <p><em>Written by Lauren Richards and Tamson Pietsch.

<p>As winter approaches, marine turtle nesting in the far north of Australia <a href="https://www.environment.gov.au/system/files/resources/2eb379de-931b-4547-8bcc-f96c73065f54/files/national-light-pollution-guidelines-wildlife.pdf">will peak</a>. When these baby turtles hatch at night, they crawl from the sand to the sea, using the relative brightness of the horizon and the natural slope of the beach as their guide.</p> <p>But when artificial lights outshine the moon and the sea, these hatchlings become disorientated. This leaves them vulnerable to predators, exhaustion and even traffic if they head in the wrong direction.</p> <p>Baby turtles are one small part of the larger, often overlooked, story of how light pollution harms wildlife across the <a href="https://theconversation.com/getting-smarter-about-city-lights-is-good-for-us-and-nature-too-69556">land</a> and <a href="https://theconversation.com/bright-city-lights-are-keeping-ocean-predators-awake-and-hungry-68965">underwater</a>.</p> <p>Green Turtle’s Battle For Survival | Planet Earth | BBC Earth.</p> <p>Today, more than 80% of people – and 99% of North American and European human populations – <a href="https://advances.sciencemag.org/content/2/6/e1600377">live under light-polluted skies</a>. We have transformed the night-time environment over substantial portions of the Earth’s surface in a very short time, relative to evolutionary timescales. Most wildlife hasn’t had time to adjust.</p> <p>In January, Australia released the <a href="https://www.environment.gov.au/biodiversity/publications/national-light-pollution-guidelines-wildlife">National Light Pollution Guidelines for Wildlife</a>. These guidelines provide a framework for assessing and managing the impacts of artificial light.</p> <p>The guidelines also identify practical solutions that can be used globally to manage light pollution, both by managers and practitioners, and by anyone in control of a light switch.</p> <p>The guidelines outline six easy steps anyone can follow to minimise light pollution without compromising our own safety.</p> <p>Although light pollution is a global problem and true darkness is hard to come by, we can all do our part to reduce its impacts on wildlife by changing how we use and think about light at night.</p> <p><strong>1. Start with natural darkness. Only add light for a specific purpose</strong></p> <p>Natural darkness should be the default at night. Artificial light should only be used if it’s needed for a specific purpose, and it should only be turned on for the necessary period of time.</p> <p>This means it’s okay to have your veranda light on to help you find your keys, but the light doesn’t need to stay on all night.</p> <p>Similarly, indoor lighting can also contribute to light pollution, so turning lights off in empty office buildings at night, or in your home before you go to sleep, is also important.</p> <p><strong>2. Use smart lighting controls</strong></p> <p>Advances in smart control technology make it easy to manage how much light you use, and adaptive controls make meeting the goals of Step 1 more feasible.</p> <p>Investing in smart controls and LED technology means you can remotely manage your lights, set timers or dimmers, activate motion sensor lighting, and even control the colour of the light emitted.</p> <p>These smart controls should be used to activate artificial light at night only when needed, and to minimise light when not needed.</p> <p><strong>3. Keep lights close to the ground, directed and shielded</strong></p> <p>Any light that spills outside the specific area intended to be lit is unnecessary light.</p> <p>Light spilling upward contributes directly to artificial sky glow – the glow you see over urban areas from cumulative sources of light. Both sky glow and light spilling into adjacent areas on the ground can disrupt wildlife.</p> <p>Installing <a href="https://www.ledlightexpert.com/Light-Shields-Explained--Outdoor-Parking-Lot-Light-Shielding_b_42.html">light shields</a> allow you to direct the light downward, which significantly reduces sky glow, and to direct the light towards the specific target area. Light shields are recommended for any outdoor lighting installations.</p> <p><strong>4. Use the lowest intensity lighting</strong></p> <p>When deciding how much light you need, consider the intensity of the light produced (lumens), rather than the energy required to make it (watts).</p> <p>LEDs, for example, are often considered an “environmentally friendly” option because they’re relatively energy efficient. But because of their energy efficiency, LEDs produce between two and five times as much light as incandescent bulbs for the same amount of energy consumption.</p> <p>So, while LED lights save energy, the increased intensity of the light can lead to greater impacts on wildlife, if not managed properly.</p> <p><strong>5. Use non-reflective, dark-coloured surfaces.</strong></p> <p>Sky glow has been shown to <a href="https://www.nature.com/articles/srep01722">mask lunar light rhythms</a> of wildlife, interfering with the celestial navigation and migration of <a href="https://science.sciencemag.org/content/313/5788/837">birds</a> and <a href="https://www.nature.com/articles/424033a">insects</a>.</p> <p>Highly polished, shiny, or light-coloured surfaces – such as structures painted white, or polished marble – are good at reflecting light and so contribute more to sky glow than darker, non-reflective surfaces.</p> <p>Choosing darker coloured paint or materials for outdoor features will help reduce your contribution to light pollution.</p> <p><strong>6. Use lights with reduced or filtered blue, violet and ultra-violet wavelengths</strong></p> <p>Most animals are sensitive to short-wavelength light, which creates blue and violet colours. These short wavelengths are known to suppress melatonin production, which is known to disrupt sleep and interfere with circadian rhythms of many animals, <a href="https://www.mdpi.com/2071-1050/11/22/6400/htm">including humans</a>.</p> <p>Choosing lighting options with little or no short wavelength (400-500 nanometres) violet or blue light will help to avoid unintended harmful effects on wildlife.</p> <p>For example, compact fluorescent and LED lights have a high amount of short wavelength light, compared low or high-pressure sodium, metal halide, and halogen light sources.</p> <p><em>Written by Emily fobert, Katherine Dafforn and Mariana Mayer-Pinto.

Be still, my beating wings: Hunters kill migrating birds on their 10,000km journey to Australia

<p>It is low tide at the end of the wet season in Broome, Western Australia. Shorebirds feeding voraciously on worms and clams suddenly get restless.</p> <p>Chattering loudly they take flight, circling up over Roebuck Bay then heading off for their northern breeding grounds more than 10,000 km away. I marvel at the epic journey ahead, and wonder how these birds will fare.</p> <p>In my former role as an assistant warden at the Broome Bird Observatory, I had the privilege of watching shorebirds, such as the bar-tailed godwit, set off on their annual migration.</p> <p>I’m now a conservation researcher at the University of Queensland, focusing on birds. Populations of migratory shorebirds are in sharp decline, and some are threatened with extinction.</p> <p>We know the destruction of coastal habitats for infrastructure development has <a href="https://www.nature.com/articles/ncomms14895">taken a big toll on these amazing birds</a>. But a study I conducted with a large international team, <a href="https://www.sciencedirect.com/science/article/pii/S0006320719311036">which has just been published</a>, suggests hunting is also a likely key threat.</p> <p><strong>What are migratory shorebirds?</strong></p> <p>Worldwide, there are 139 migratory shorebird species. About 75 species breed at high latitudes across Asia, Europe, and North America then migrate south in a yearly cycle.</p> <p>Some 61 migratory shorebird species occur in the Asia-Pacific, within the so-called East Asian-Australasian Flyway. This corridor includes 22 countries – from breeding grounds as far north as Alaska and Siberia to non-breeding grounds as far south as Tasmania and New Zealand. In between are counties in Asia’s east and southeast, such as South Korea and Vietnam.</p> <p>The bar-tailed godwits I used to observe at Roebuck Bay breed in Russia’s Arctic circle. They’re among about 36 migratory shorebird species to visit Australia each year, <a href="https://www.environment.gov.au/system/files/resources/da31ad38-f874-4746-a971-5510527694a4/files/revision-east-asian-australasian-flyway-population-sept-2016.pdf">amounting to more than two million birds</a>.</p> <p>They primarily arrive towards the end of the year in all states and territories – visiting coastal areas such as Moreton Bay in Queensland, Eighty Mile Beach in Western Australia, and Corner Inlet in Victoria.</p> <p>Numbers of migratory shorebirds have been falling for many species in the flyway. The trends have been detected since the 1970s <a href="https://www.publish.csiro.au/MU/MU15056">using citizen science data sets</a>.</p> <p>Five of the 61 migratory shorebird species in this flyway are globally threatened. Two travel to Australia: the great knot and far eastern curlew.</p> <p>Threats to these birds are many. They include the <a href="http://decision-point.com.au/article/between-a-rock-and-a-hard-place/">loss of their critical habitats</a> along their migration path, <a href="https://theconversation.com/contested-spaces-saving-nature-when-our-beaches-have-gone-to-the-dogs-72078">off-leash dogs disturbing them on Australian beaches</a>, and climate change likely <a href="https://theconversation.com/arctic-birds-face-disappearing-breeding-grounds-as-climate-warms-62656">contracting their breeding grounds</a>.</p> <p><strong>And what about hunting?</strong></p> <p>During their migration, shorebirds stop to rest and feed along a network of wetlands and mudflats. They appear predictably and in large numbers at certain sites, making them relatively easy targets for hunters.</p> <p>Estimating the extent to which birds are hunted over large areas was like completing a giant jigsaw puzzle. We spent many months scouring the literature, obtaining data and reports from colleagues then carefully assembling the pieces.</p> <p>We discovered that since the 1970s, three-quarters of all migratory shorebird species in the flyway have been hunted at some point. This includes almost all those visiting Australia and four of the five globally threatened species.</p> <p>Some records relate to historical hunting that has since been banned. For example the Latham’s snipe, a shorebird that breeds in Japan, was legally hunted in Australia until the 1980s. All migratory shorebirds are now legally protected from hunting in Australia.</p> <p>We found evidence that hunting of migratory shorebirds has occurred in 14 countries, including New Zealand and Japan, with most recent records concentrated in southeast Asia, such as Indonesia, and the northern breeding grounds, such as the US.</p> <p>For a further eight, such as Mongolia and South Korea, we could not determine whether hunting has ever occurred.</p> <p>Our research suggests hunting has likely exceeded sustainable limits in some instances. Hunting has also been pervasive – spanning vast areas over many years and involving many species.</p> <p><strong>Looking ahead</strong></p> <p>The motivations of hunters vary across the flyway, according to needs, norms, and cultural traditions. For instance, <a href="https://academic.oup.com/condor/article-abstract/121/2/duz023/5523065?redirectedFrom=fulltext">Native Americans in Alaska</a> hunt shorebirds as a food source after winter, and <a href="https://static1.squarespace.com/static/5c1a9e03f407b482a158da87/t/5c42eb8e8a922d3a72d42879/1547889551203/Chowdury-Sonadia.pdf">low-income people in Southeast Asia hunt and sell them</a>.</p> <p>National governments, supported by NGOs and researchers, must find the right balance between conservation and other needs, such as food security.</p> <p>Efforts to address hunting are already underway. This includes mechanisms such as the <a href="https://www.cms.int/en/taskforce/ittea">United Nations Convention</a> on Migratory Species and the East Asian-Australasian Flyway <a href="https://www.eaaflyway.net/task-force-on-illegal-hunting-taking-and-trade-of-migratory-waterbirds/">Partnership</a>. Other efforts involve helping hunters find <a href="https://www.birdlife.org/asia/news/targeting-hunters-save-spoon-billed-sandpiper">alternative livelihoods</a>.</p> <p>Our understanding of hunting as a potential threat is hindered by a lack of coordinated monitoring across the Asia-Pacific.</p> <p>Additional surveys by BirdLife International, as well as <a href="https://cpree.princeton.edu/research/biodiversity/saving-endangered-species">university researchers</a>, is underway in southeast Asia, China, and Russia. Improving hunting assessments, and coordination between them, is essential. Without it, we are acting in the dark.</p> <p><em>The author would like to acknowledge the contributions of Professor Richard A. Fuller (University of Queensland), Professor Tiffany H.

The coronavirus survival challenge for NZ tourism: affordability and sustainability

<p>Until a trans-Tasman travel bubble is <a href="https://www.abc.net.au/news/2020-05-04/trans-tasman-bubble-coronavirus-what-might-happen-next/12212580">established</a>, there is little doubt the New Zealand tourism industry will <a href="https://www.rnz.co.nz/news/national/413845/covid-19-domestic-travellers-eyed-to-keep-tourism-sector-viable-after-lockdown">rely entirely</a> on domestic travel post-COVID-19.</p> <p>Without underplaying the impact the pandemic will have on discretionary spending in both countries, however, there may be a silver lining to the crisis.</p> <p>New Zealand is in the fortunate position of having an <a href="https://tia.org.nz/about-the-industry/quick-facts-and-figures/">already strong</a> domestic tourism sector. Domestic tourists spent NZ$23.7 billion annually (or NZ$65 million a day) pre-COVID-19, compared to a total spend of NZ$12.7 billion (or NZ$47 million a day) by international visitors. <a href="https://openrepository.aut.ac.nz/handle/10292/11857">Research</a> pre-COVID-19 showed 65% of New Zealanders wanted to explore more of their country, a figure expected to increase.</p> <p>True, New Zealanders generally don’t have the deep pockets international tourists have. Their higher overall spend is a reflection of their numbers, not their bank balances. But with the big ticket tourist attractions now missing the bigger spenders, the market will rule.</p> <p>Regional tourism organisations, attractions and operators may need to rethink their offerings and their pricing. While tramping the <a href="https://www.doc.govt.nz/parks-and-recreation/things-to-do/walking-and-tramping/great-walks/">great walks</a> may be perfectly affordable for a family of four, taking the family on a whale watch, a bungy jump or a cruise on Milford Sound may not be – especially as parts of one big holiday. Indeed, it has been found that <a href="https://openrepository.aut.ac.nz/handle/10292/11857">price</a> is the major decision-making factor for 30% of New Zealanders when it comes to holidays.</p> <p>So this is also an opportunity to give New Zealanders back a piece of the summer pie – not only for the COVID-19 recovery but in the longer term. Summers have tended to be characterised by a large influx of international tourists, with Kiwis settling for shoulder seasons (and unfavourable weather) to tramp the famous tracks when they are <a href="https://www.stuff.co.nz/environment/99088942/tourists-outnumber-new-zealanders-on-the-great-walks--and-the-gaps-growing">less crowded</a>.</p> <p>But domestic tourists who have grown accustomed to off-peak holidays away from high-cost destinations will soon tip the scales. Now is the time for operators to win back their hearts.</p> <p>With New Zealand’s gradual easing of its strict lockdown (possibly to the stage of allowing non-essential travel by mid-May), tourism can clearly support the economic revival of local communities. The challenge is how to reinvent New Zealand tourism as an initially purely domestic industry.</p> <p>Overall, only a handful of New Zealand destinations have depended entirely on international tourists. These also happen to be the places most heavily associated with overtourism in the past. Given that the <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2020.1759131">growth model</a> driven by short-term, dollars-first business thinking has led to an <a href="https://www.noted.co.nz/money/money-economy/nz-tourists-should-we-limit-number-visitors">unsustainable</a> tourism market, might this also be a chance to restore some equilibrium?</p> <p>That will mean no more killing the goose that lays the <a href="https://www.pce.parliament.nz/publications/pristine-popular-imperilled-the-environmental-consequences-of-projected-tourism-growth">golden egg</a>. Some hotspots, such as the <a href="https://www.tongarirocrossing.org.nz/">Tongariro Alpine Crossing</a> and <a href="https://www.thecoromandel.com/activities/must-do/hot-water-beach/">Coromandel’s Hot Water Beach</a> may be managed by restricting visitor numbers.</p> <p>Such strategies have long been in place in other places, such as the <a href="https://www.doc.govt.nz/parks-and-recreation/places-to-go/fiordland/places/fiordland-national-park/things-to-do/tracks/milford-track/">booking requirement</a> for the Milford Track. We have also seen tremendous problems associated with too many cruise ships in too small places. Akaroa is a prime example, and limiting both the number of visits and the size of vessels may be a feasible <a href="https://www.radionz.co.nz/audio/player?audio_id=2018685520">future strategy</a>.</p> <p>As part of our own research (yet to be published) into the pressing issues of overtourism we conducted interviews with various tourism stakeholders around New Zealand, including city and regional councils, the Department of Conservation, residents and operators. This took place just before New Zealand’s strictest lockdown level was imposed, without any real foreknowledge of the eventual economic impact of COVID-19.</p> <p>Nonetheless, our interviewees shared very similar sentiments when it came to how the industry can evolve sustainably only if New Zealanders themselves embrace the behaviours they expect (and sometimes demand) of foreign tourists. According to our subjects, too many Kiwis still hold on to a past when the country’s population was half its current size and SUVs and large motorhomes didn’t crowd the roads and parking lots.</p> <p>Initiatives such as the <a href="https://tiakinewzealand.com/">Tiaki Promise</a>, which promote environmental and cultural sensitivity to tourists, have largely targeted international visitors. These now need to turn the lens inwards so that Kiwis become better ambassadors within their own backyard.</p> <p>Kiwis love their country, but they will now need to truly discover what it has to offer, not only for a weekend of tramping or a quick getaway, but for their main summer holiday. And they will have to become better kaitiaki (or guardians) of their homeland in the process.</p> <p>The absence of international tourists will be a huge challenge, but also an opportunity. If we get it right, when those foreign visitors are allowed to return (most likely at first from Australia) we will have found ways to grow – or limit – their numbers and their expectations so that our tourism industry can thrive as well as survive.</p> <p><em>Written by Sabrina Seeler and Michael Lueck.
