Tragic confirmation of Julian Sands' death

<p>Missing British actor Julia Sands has been confirmed dead at age 65.</p> <p>Californian hikers <a href="https://www.oversixty.co.nz/news/news/human-remains-found-in-search-for-missing-actor" target="_blank" rel="noopener">discovered human remains</a> in the surrounding area where the actor was said to have vanished, and the remains have now been identified as Sands, according to authorities.</p> <p>"The identification process for the body located on Mt. Baldy on June 24, 2023, has been completed and was positively identified as 65-year-old Julian Sands of North Hollywood," the San Bernardino Sheriff's Department said in a statement.</p> <p>"The manner of death is still under investigation, pending further test results," it continued.</p> <p>"We would like to extend our gratitude to all the volunteers that worked tirelessly to locate Mr. Sands.”</p> <p>Sands’ tragic death comes days after a search and rescue was resumed by the San Bernardino Sherrif’s Office, which had been leading the searches for the missing actor over the past six months.</p> <p>The local region experienced wild and uncharacteristic weather which led to a more difficult search.</p> <p>Sands was first reported missing in January after setting out to hike the notoriously dangerous Mount Baldy, which rises more than 10,000 feet (approx. 3048 metres) east of Los Angeles and has been hit with severe storms during their winter season.</p> <p>"We continue to hold Julian in our hearts with bright memories of him as a wonderful father, husband, explorer, lover of the natural world and the arts, and as an original and collaborative performer," the statement said.</p> <p>Sands’ family released a statement at the time of his disappearance, saying, "Our heartfelt thanks to the compassionate members of the San Bernardino County Sheriff's Department who are coordinating the search for our beloved Julian, not least the heroic search teams listed below who are braving difficult conditions on the ground and in the air to bring Julian home,”</p> <p>Sands’ son Henry also released a statement in April to praise the San Bernardino Sheriff’s Department for their continued efforts in rescuing his father.</p> <p>"I am hugely appreciative for all the efforts made so far from the volunteer search and rescue climbers and the San Bernardino county sheriff team to bring my father home," Henry Sands told <em>The Times</em>.</p> <p><em>Image credit: Getty</em></p>

Planting soft barriers such as mangroves and dense, deep-rooting vegetation can provide a more enduring solution. It also restores fish habitat, purifies water and eases floods.</p> <p>Acknowledging the well-being of people and nature as interconnected has important implications for decisions about relocating people from high-risk areas. Effective planned retreat strategies must not only get people out of harm’s way, but account for where they will move and how precious ecosystems will be protected as demand for land supply shifts. Nature-based solutions must be built into retreat policies too.</p> <p>As the Australian Academy of Science’s <a href="https://www.science.org.au/news-and-events/events/launch-national-strategy-just-adaptation">Strategy for Just Adaptation</a> explains, effective adaptation also embeds equity and justice in the process. <a href="https://link.springer.com/article/10.1007/s10584-019-02535-1">Research</a> on historic retreat strategies has shown that a failure to properly consider and respect people’s choices, resources and histories can further entrench inequities.

As climate activist Greta Thunburg <a href="https://www.youtube.com/watch?v=ZwD1kG4PI0w">says</a>:</p> <blockquote> <p>“Hope is not passive. Hope is not blah blah blah. Hope is telling the truth.

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.

The world may lose half its sandy beaches by 2100: It’s not too late to save most of them

<p>For many coastal regions, sea-level rise is a looming crisis threatening our coastal society, livelihoods and coastal ecosystems. <a href="https://www.nature.com/articles/s41558-020-0697-0">A new study</a>, published in Nature Climate Change, has reported the world will lose almost half of its valuable sandy beaches by 2100 as the ocean moves landward with rising sea levels.</p> <p>Sandy beaches comprise about a third of the world’s coastline. And Australia, with nearly 12,000 kilometres at risk, could be hit hard.</p> <p>This is the first truly global study to attempt to quantify beach erosion. The results for the highest greenhouse gas emission scenario are alarming, but reducing emissions lead to lower rates of coastal erosion.</p> <p>Our best hope for the future of the world’s coastlines and for Australia’s iconic beaches is to keep global warming as low as possible by urgently reducing greenhouse gas emissions.</p> <p><strong>Losing sand in coastal erosion</strong></p> <p>Two of the largest problems resulting from <a href="https://www.ipcc.ch/srocc/">rising sea levels</a> are coastal erosion and an already-observed increase in the frequency of coastal flooding events.</p> <p>Erosion during storms can have dramatic consequences, particularly for coastal infrastructure. We saw this in 2016, when <a href="https://theconversation.com/sydneys-wild-weather-shows-home-owners-are-increasingly-at-risk-60621">wild storms</a> removed sand from beaches and damaged houses in Sydney.</p> <p>After storms like this, beaches often gradually recover, because sand from deeper waters washes back to the shore over months to years and in some cases decades. These dramatic storms and the long-term <a href="https://www.sciencedirect.com/science/article/abs/pii/S002532271630010X">sand supply</a> make it difficult to identify any beach movement in the recent past from sea-level rise.</p> <p>What we do know is that the rate of sea-level rise has <a href="https://theconversation.com/contributions-to-sea-level-rise-have-increased-by-half-since-1993-largely-because-of-greenlands-ice-79175">accelerated</a>. It has increased by half since 1993, and is continuing to accelerate from ongoing greenhouse gas emissions.</p> <p>If we continue to emit high levels of greenhouse gases, this acceleration will continue through the 21st century and <a href="https://theconversation.com/what-does-the-science-really-say-about-sea-level-rise-56807">beyond</a>. As a result, the supply of sand may not be able to keep pace with rapidly rising sea levels.</p> <p><strong>Projections for the worst-case scenario</strong></p> <p>In the most recent Intergovernmental Panel on Climate Change (IPCC) <a href="https://www.ipcc.ch/srocc/">report</a>, released last year, the highest greenhouse gas emissions scenario resulted in global warming of more than 4°C (relative to pre-industrial temperatures) and a likely range of sea-level rise between 0.6 and 1.1 metres by 2100.</p> <p>For this scenario, this new study projects a global average landward movement of the coastline in the range of 40 to 250 metres if there were no physical limits to shoreline movement, such as those imposed by sea walls or other coastal infrastructure.</p> <p>Sea-level rise is responsible for the vast majority of this beach loss, with faster loss during the latter decades of the 21st century when the rate of rise is larger. And sea levels will continue to rise for centuries, so beach erosion would continue well after 2100.</p> <p>For southern Australia, the landward movement of the shoreline is projected to be more than 100 metres. This would damage many of Australia’s iconic tourist beaches such as Bondi, Manly and the Gold Coast. The movement in northern Australia is projected to be even larger, but more uncertain because of ongoing historical shoreline trends.</p> <p><strong>What happens if we mitigate our emissions</strong></p> <p>The above results are from a worst-case scenario. If greenhouse gas emissions were reduced such that the 2100 global temperature rose by about 2.5°C, instead of more than 4°C, then we’d reduce beach erosion by about a third of what’s projected in this worst-case scenario.</p> <p>Current global policies would result in about <a href="https://climateactiontracker.org/global/cat-thermometer/">3°C of global warming</a>. That’s between the 4°C and the 2.5°C scenarios considered in this beach erosion study, implying our current policies will lead to significant beach erosion, including in Australia.</p> <p>Mitigating our emissions even further to achieving the Paris goal of keeping temperature rise to well below 2°C would be a major step in reducing beach loss.</p> <p><strong>Why coastal erosion is hard to predict</strong></p> <p>Projecting sea-level rise and resulting beach erosion are particularly difficult as both depend on many factors.</p> <p>For sea level, the major problems are estimating the contribution of melting Antarctic ice flowing into the ocean, how sea level will change on a regional scale, and the amount of global warming.</p> <p>The beach erosion calculated in this new study depends on several new databases. The databases of recent shoreline movement used to project ongoing natural factors might already be influenced by rising sea levels, possibly leading to an overestimate in the final calculations.</p> <p><strong>The implications</strong></p> <p>Regardless of the exact numbers reported in this study, it’s clear we will have to adapt to the beach erosion that we can no longer prevent, if we are to continue enjoying our beaches.</p> <p>This means we need appropriate planning, such as beach nourishment (adding sand to beaches to combat erosion) and other soft and hard engineering solutions. In some cases, we’ll even need to retreat from the coast to allow the beach to migrate landward.</p> <p>And if we are to continue to enjoy our sandy beaches into the future, we cannot allow ongoing and increasing greenhouse gas emissions. The world needs urgent, significant and sustained global mitigation of greenhouse gas emissions.</p> <p><em>Written by John Church.

Where exactly does beach sand come from?

<p>There’s more to beach sand than meets the eye. It has stories to tell about the land, and an epic journey to the sea. That’s because mountains end their lives as sand on beaches.</p> <p>Over time, mountains erode. The mud, sand, gravel, cobbles and boulders they shed are washed into streams, which come together to form rivers. As they flow down to the sea, all this sediment is ground up and worn down in nature’s version of a rock tumbler.</p> <p>Big rocks break down into smaller pieces, so most of what reaches the sea is mud. These silt and clay particles are too small to perceive with the naked eye. But you can see individual grains of sand, which are just bigger bits of rock.</p> <p>Next time you’re at the beach, pick up a handful of sand and look closely at it. Are all the grains the same color, or a rainbow assortment? Are they jagged and angular, or smooth and round?</p> <p>Different colors of sand come from different minerals, like khaki <a href="https://en.wiktionary.org/wiki/feldspar#/media/File:Feldspar_1659.jpg">feldspar</a>, smoky white <a href="https://en.wikipedia.org/wiki/Quartz#/media/File:Quartz,_Tibet.jpg">quartz</a>, green <a href="https://geology.com/minerals/olivine.shtml">olivine</a> or black <a href="https://en.wikipedia.org/wiki/Basalt#/media/File:BasaltUSGOV.jpg">basalt</a>. The mix of colors in beach sand tells you what kinds of rocks produced it.</p> <p>The shape of sand grains also provides clues about where they come from. Angular grains of the same type of sand have not traveled as far as smooth round grains, which have been more worn down. And weak rocks break down to mud faster than hard rocks, so sand tends to be made of the harder types that break down slowly.</p> <p>About a tenth of the supply of sediment that reaches the sea is sand. These particles are between about half a millimeter and 2 millimeters in size – roughly as thick as a penny. These particles are large enough that they don’t flow right out to the deep sea.</p> <p>But the beach is just a temporary stop for sand. Big waves pull it offshore, and smaller waves push it along the coast. So keeping a beach nourished with sand is essential for keeping it sandy.</p> <p>Many beach towns spend millions of dollars to rebuild eroded beaches with new sand.</p> <p>Yet today many beaches are starving. Many dams trap the sand that flows down rivers, piling it up in reservoirs. All in all, human activity has cut off about <a href="http://dx.doi.org/10.1126/science.1109454">half the sand</a> that would otherwise end up on the world’s beaches.</p> <p>But humans haven’t turned the waves off, so as beach sand washes away and isn’t replenished, the shoreline erodes. That means that many beaches around the world are shrinking, slowly but surely.</p> <p>So next time you dig your toes into beach sand think about the epic journey it took to arrive beneath your feet. Take a moment to think about where the sand came from and where it’s going.</p> <p><em>Written by David R. Montgomery.

Tourists face jail time over sand theft

<p><span>“Take nothing but pictures, leave nothing but footprints, kill nothing but time” – this often heard phrase has become a rule of thumb while travelling, but some still could not resist the urge to bring a piece of paradise home from the holidays.</span></p> <p><span>A French couple had to deal with the consequences as they are facing up to six years in prison for taking 40kg of sand from a beach in the Italian island of Sardinia.</span></p> <p><span>14 plastic bottles containing around 40kg of white sand from a beach in Chia, southern Sardinia were seized from the car during routine checks, police said.</span></p> <p><span>The couple, a man and a woman in their 40s, said they wanted to bring the sand home as a “souvenir” and did not realise they were committing a crime.</span></p> <p><span>The Italian island’s white sand is protected as a public good, and tourists who remove it from the island are subject to fines of up to €3,000 and possible imprisonment.</span></p> <p><span>Residents of the Mediterranean island have been protesting the theft of sand, stones and seashells by tourists, <a href="https://www.bbc.com/news/world-europe-41031029"><em>BBC</em></a> reported.</span></p> <p><span>“The people of Sardinia are very angry with tourists that steal shells and sand, because it's a theft [from] future generations that also puts at risk a delicate environment,” a police officer told <a href="https://edition.cnn.com/travel/article/sardinia-sand-theft-arrest-scli-intl/index.html"><em>CNN</em></a>.</span></p> <p><span>According to environmental scientist and Sardinian resident Pierluigi Cocco, there are two threats to the island’s sandy beaches. “One is due to erosion, which is partly natural and partly induced by the increasing sea level due to climate change; the second is sand stealing by tourists,” Cocco told the <a href="https://www.bbc.com/news/world-europe-49394828"><em>BBC</em></a>.</span></p> <p><span>"Only a fraction of the tourists visiting Sardinia spend their time digging up to 40kg of sand each. But if you multiply half that amount times 5 per cent of the one million tourists per year, in a few years that would contribute significantly to the reduction of beaches – the main reason why tourists are attracted by the island of Sardinia.”</span></p> <p><span>In 1994, access to the famous pink beach on Budelli island off Sardinia were restricted over concerns about the degraded environment. In 2016, a woman who took the sand from the beach <a href="https://www.theguardian.com/world/2019/aug/19/french-tourists-in-hot-water-in-sardinia-over-sand-souvenir">returned it after more than two decades</a>. “I read in some newspapers and heard on the TV what this sand is and how it is made,” she said. “I understood how unique Sardinia is.

This beach officially has the whitest sand in Australia

<p><em><strong>Noel Schoknecht is a senior research associate at Murdoch University in Perth, Western Australia.</strong></em></p> <p>In 2005, when I was chair of the <span style="text-decoration: underline;"><strong><a href="http://www.soilscienceaustralia.org/ncst" target="_blank">National Committee on Soil and Terrain</a></strong></span>, I started a debate: where is Australia’s whitest beach? This was a diversion from the committee’s normal business of looking at the sustainable management of Australia’s soils, but it led down a path I hadn’t expected.</p> <p>What began as a bit of after-hours banter became a serious look across Australia in search of our whitest beaches. New South Wales had already laid claim to the title, arguing that Hyams Beach at Jervis Bay has the <span style="text-decoration: underline;"><strong><a href="https://open.abc.net.au/explore/28273" target="_blank">whitest sand in the world</a></strong></span>, purportedly backed up by Guinness World Records.</p> <p>As it turned out, both claims were false. Guinness World Records has no such category, and the whitest beach (as we found) is actually elsewhere.</p> <p>So we drafted terms of reference, and the search for <span style="text-decoration: underline;"><strong><a href="http://www.whitestbeach.com/" target="_blank">Australia’s Whitest Beach</a></strong></span> began. Over the next year samples were collected across the nation. The criteria were simple: samples had to be taken from the swash zone (the gently sloping area between the water and the dunes) and the samples could not be treated in any way apart from air-drying. No bleaching. No sieving out of impurities. Marine environment only.</p> <p>The results of the first judging in 2006 were startling. Of all the states and territories, the much promoted Hyams Beach in New South Wales came in fourth. Third was Victoria, second Queensland, and first Western Australia.</p> <p>The other states and territories came in at Tasmania fifth, Northern Territory sixth, and South Australia seventh. The ACT didn’t have a beach to sample, although technically some of the Commonwealth lands around our coasts could possibly come in under their banner (but that’s another debate altogether).</p> <p style="text-align: center;"><img width="500" height="NaN" src="https://images.theconversation.com/files/198662/original/file-20171211-9383-1y7qak8.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip"/></p> <p style="text-align: center;"><em>A sample of the main contenders for the whitest beach in Australia. Unfortunately, samples submitted from South Australia didn’t make the final cut.</em></p> <p>The winning beach was Lucky Bay in Cape Le Grand National Park on WA’s south coast, but in reality any of the beaches in this area could have been winners – Hellfire Bay, Thistle Cove and Wharton’s beach (just to name a few) are all magnificently white.</p> <p>A quick qualification here: the southwestern end of Lucky Bay, where many people enter the beach, is covered with seaweed – not the whitest bit! I should also note that all of the finalists in the whitest beach challenge were in their own right fabulously white. But when compared side-by-side, some beaches are clearly whiter than others.</p> <p>The Queensland team felt aggrieved, so in 2007 I carried out a repechage with new samples from Queensland at Whitehaven Beach in the Whitsundays, and Lake McKenzie on Fraser Island. Lake McKenzie was ultimately disallowed as it is a freshwater lake and the rules stipulated a marine environment. Meanwhile, Whitehaven didn’t quite cut the mustard in the judging and Lucky Bay in WA was again the winner.</p> <p style="text-align: center;"><img width="500" height="NaN" src="https://images.theconversation.com/files/198665/original/file-20171211-9416-v5kr92.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip"/></p> <p style="text-align: center;"><em>Whitehaven beach in Queensland just missed out on the top spot in the recount.</em></p> <p><strong>So what makes a beach white, and is it important anyway?</strong></p> <p>The assessments were based on a visual comparison, so to remove any possible visual bias after the 2007 challenge all the samples were scanned for their reflectance – how much light bounced off the sand, essentially – in the visible and infrared wavelengths. Our assumption was that higher reflectance throughout the visual spectrum correlates with greater whiteness.</p> <p>As it turned out, the results from the scanning exactly correlated with the visual assessments. The eye is quite good at discerning small differences in colour and reflectance. (More background and the results from the competition are available <span style="text-decoration: underline;"><strong><a href="http://www.whitestbeach.com/" target="_blank">here</a></strong></span>.)</p> <p>So what makes a beach white? Obviously, a pristine environment helps. Another factor is the distance from rivers, which deliver coloured organic and clay contaminants to the coast.</p> <p>The geology of the area and the source of the sand are also critical, with quartz seemingly a major requirement for fine sands. Most white sandy beaches are derived from granitic, or less commonly sandstone, geologies that weather to produce fine, frosted quartz sand grains. Interestingly, sands made from shell or coral fragments just aren’t as white.</p> <p style="text-align: center;"><img width="500" height="NaN" src="https://images.theconversation.com/files/198671/original/file-20171212-9392-1b85svb.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip"/></p> <p style="text-align: center;"><em>The source of the sand is very important; sand made from shells or coral aren’t as white as quartz.</em></p> <p><strong>Is it important?</strong></p> <p>While this competition began in fun, I do believe it’s important. Beaches are places of refuge in this crazy world, and a pristine white beach indicates a cleanliness that is worth striving for. The reflectance of light off these sands through shallow waters near the beach creates a surreal, magical turquoise colour. White beaches are like the canary in the coalmine – once they’re spoiled, we know we’re in trouble.</p> <p>Even though this study was a first look at some of Australia’s whitest beaches, and sampling was limited, it did highlight the sheer number of wonderful sandy beaches that Australia has.</p> <p>The story’s not finished though. There are many white beaches out there yet to be sampled, and if you’d like to alert me to your potentially award-winning beach please <span style="text-decoration: underline;"><strong><a href="https://theconversation.com/whitestbeachinaustralia@gmail.com" target="_blank">email me</a></strong></span> or leave a comment on the <span style="text-decoration: underline;"><strong><a href="https://whitestbeach.com/feedback/" target="_blank">whitest beach website</a></strong></span>.</p> <p>It’s our responsibility, and I believe honour, to protect these amazing places. I’m sure there are more wonderful beaches out there that we haven’t sampled which may defeat Lucky Bay.</p> <p>Shelburne Bay in northern Queensland, for example, is a contender yet to be sampled, and there are some magnificent beaches on the east coast of Tasmania. Whatever the outcome, let’s celebrate the natural wonders that surround our country.</p> <p><em>Written by Noel Schoknecht.

Dramatic black sand beaches of Auckland’s west coast

<p><strong><em>New Zealand travel writer Justine Tyerman and family visit the dramatic black sand beaches of Auckland’s West Coast…</em></strong></p> <p>The first glimpse of the black sand beach at Piha with its mountainous surf thundering in from the Tasman Sea, swirling around the haunches of the giant crouching lion, stopped us in our tracks. Accustomed to the golden sands and more docile surf of the East Coast, the wild West Coast where the sand shone like pewter or black pearls, seemed other-worldly.</p> <p>The sound of sirens as the Piha lifeguards roared out through the ferocious waves in their IRBs on one of their famous rescue missions added to the drama of the scene.</p> <p>Short of time, we chose Piha as the base for our annual family get-together because it’s close to Auckland and none of us had ever been there before. Just 50-60 minutes’ drive from the airport, it was easy for us to collect our far-flung family flying in from distant places, and run away for a long weekend together.</p> <p><strong>The Hillary Trail</strong></p> <p>We spent a long weekend hiking the spectacular Hillary Trail, a 76km multi-day hike from the Arataki Visitor Centre in the Waitakere Ranges to Muriwai Beach. It’s named in honour of the famous Kiwi explorer and mountaineer Sir Edmund Hillary who came to the rugged Waitakere Ranges to prepare for his expeditions.</p> <p>During our stay, we managed to tick off a sizeable chunk of the trail from Anawhata to Whatipu, albeit the cushy way, returning to our luxurious home base every night.</p> <p>A highlight was the Piha to Karekare stretch of the walkway which was high above the coastline and rich in history. The track begins at the end of Log Race Road, a reminder of the intensive logging of kauri in the area during the late 1800s-early 1900s. Logs were transported by tramway from Anawhata to Paratutai Wharf at Whatipu where they were loaded onto ships for export.</p> <p>Also at the start of the track is a relic of WW2, the foundations of a radar station where the skies and seas were scanned for signs of invading Japanese. Sited on Hikurangi, the highest hill in the region, the station was part of a coastal network, and a key part of New Zealand’s home defence system.</p> <p>The station was later used in experiments to pinpoint sources of radio emissions from space, research which laid the foundations for the modern science of radio astronomy. Information boards and audio recordings give a fascinating account of the life of the station.</p> <p>Te Ahua Point Lookout is a site of deep historical significance to Te Kawerau a Maki iwi, the tangata whenua of the region. Gazing out to sea, there’s a striking pou (carving) of a beautiful, young noble woman named Hinerangi after an honoured Turehu ancestress. Hinerangi and her husband lived happily at Karekare for many years until one day he was swept away by a wave while fishing off the rocks at Te Kawa Rimurapa in Mercer Bay.</p> <p>Grief-stricken, Hinerangi climbed to the top of the highest cliff and sat there for days, scanning the turbulent seas, longing for her husband’s return. She eventually died of a broken heart and her sad face is said to be etched in the cliff face. The site is called Te Ahua o Hinerangi — The Likeness of Hinerangi. Recent archaeological excavation shows the headland is one of the oldest settled areas of the Waitakere Ranges and was a sanctuary and defensive position for Te Kawerau a Maki.</p> <p>The track took us high above Mercer Bay with its sphinx-like rock formations to a lookout where we could see the shimmering black sands of Karekare Beach, recently named one of the world’s most beautiful beaches, and the vast expanse of the Whatipu Scenic Reserve in the distance.</p> <p>That evening we rewarded ourselves with burgers and fish and chips at the Piha Surf Lifesaving Club as the sun set over the Tasman, an awesome sight for a family of East Coasters who are accustomed to sunrises over the Pacific but seldom see the sun sink into the ocean. It was dazzling.</p> <p><strong>Home swapping</strong></p> <p>Accommodation was at a premium that weekend, but thanks to my membership of the international home swap club, Love Home Swap, we found a primo place in a perfect location.</p> <p>I joined Love Home Swap in 2013 and the Piha house is one of many fabulous private homes we’ve stayed at around the world. We stayed five nights and paid precisely nothing… unless you take into account the beer and nibbles we shared with owners, Dave and Emma, who joined us for a chat one evening.</p> <p>That’s another great factor about Love Home Swap — you make new friends wherever you go, people who not only entrust you with their lovely homes but also introduce you to their communities and networks, and give you the inside goss on where to wine, dine, hike and sightsee.</p> <p>Dave, an advanced paramedic and former Piha lifeguard, and Emma, who works for the design label Sabatini, were delightful company with a wealth of knowledge about the area. We felt like celebrities after they told us we were living in a film set for the new TV series 800 Words which screens on TVNZ1 on Sunday evenings.</p> <p>We’ve kept in touch with many people we’ve met through Love Home Swap over the years.</p> <p>The ‘stays’ are managed by an exchange of points, a form of currency, rather than an actual home swap, although that’s always an option.</p> <p>It often does not suit members to swap simultaneously so the points system provides the flexibility and freedom to stay wherever and whenever you choose. Dave and Emma earned 750 points for our stay which they can ‘spend’ anywhere in the world at a time that suits them. Keen surfers, they may well turn up on our doorstep in Gisborne one day.</p> <p><strong>The house</strong></p> <p>Built of silvery Lawsons cypress, the design of the house was visually striking, featuring two cubes of different heights, the larger, taller one resting on the smaller, lower one, with a void between. A front north-facing deck leads to a tropical sun-filled garden and outside dining area with a massive macrocarpa table, while the back deck with its spa pool are suspended above the dark, moody, misty Waitakere Ranges with Karekare Beach in the distance.</p> <p>A covered passageway frames the view like a living artwork. Huge glass doors can be swung into place to enclose it and provide shelter in wet or windy weather.</p> <p>Designed by Tim Dorrington of Dorrington Atcheson Architects, the house was built with easy-care, hard-wearing materials like the polished concrete floors in the open plan kitchen-living-dining area.</p> <p>A hefty macrocarpa servery board, hand-made by Dave, sits on the recycled oak kitchen island, while the main workbench is stainless steel.</p> <p>A cosy, carpeted lounge with panoramic windows overlooking the wooded Waitakeres and Karekare Beach steps down from the kitchen. A comprehensive TV/home entertainment centre lines one wall while comfy bean bags, built-in seating and a wood-burning stove create a snug, intimate feeling.</p> <p>Upstairs, spacious, airy bedrooms, balconies and a bathroom also have spectacular views.</p> <p>It was the perfect location for our foursome to rebond after too long apart. The place just seemed to have good feng shui. It’s a house with a smile.</p> <p>Have you ever been to Auckland?</p> <p><em>Image credit: Justine Tyerman</em></p> <p><em>Justine Tyerman stayed at Dave and Emma’s Love Home Swap property at Piha.</em></p> <p><em>Visit <a href="http://www.lovehomeswap.com/" target="_blank"><strong><span style="text-decoration: underline;">Love Home Swap</span></strong></a> to view over 100,000 properties in 150 countries:</em></p> <p><em>Getting there: <a href="http://www.jucy.co.nz/our-vehicles/motor-homes/casa-plus/%20%20%20" target="_blank"><strong><span style="text-decoration: underline;">JUCY Rentals</span></strong></a>.</em></p>
