Amazon Deforestation Threatens South America's Water Security
By Paul Brown
The continued destruction of the Amazon to exploit its resources for mining, agriculture and hydro-power is threatening the future of the South American continent, according to a report by campaigning groups using the latest scientific data.

Five countries—Bolivia, Brazil, Colombia, Ecuador and Peru—share the Amazon, and for all of them the forest area occupies more than 40 percent of their territory. All face threats to their water supply, energy production, food and health.
In addition, the report says, because of the over-exploitation of the region, rainfall will fall by 20 percent over a heavily-populated area far to the south of Amazonia known as the La Plata basin, covering parts of Argentina, Brazil, Bolivia, Paraguay and Uruguay.
Last month it was reported that deforestation in Amazonia had increased by almost one-third in the past year, with an area equal to 50 football fields destroyed every minute since 2000.
The report, the Amazonia Security Agenda, authored by the Global Canopy Programme and CIAT, the International Centre for Tropical Agriculture, says the prosperity of the region is based on the abundance of water.
There always seemed to be an endless supply of water, but the combination of industrial and agricultural pollution and droughts is creating a once unthinkable vulnerability for the five countries of Amazonia.
Profits Syphoned Off
The huge wealth being generated from the forests comes with large-scale environmental and social costs. Local people do not benefit, and the profits from minerals, mining and agriculture are syphoned out of the region.
The large-scale economic development of the region causes deforestation. That in turn is threatening not only the wellbeing of the local people but the economic stability of the industries themselves.
Climate change is adding to both the uncertainty and the instability. Increasing temperatures, as much as 3.5 degrees Celsius in the near future, changing rainfall patterns and more intense and frequent extreme weather events will have further impacts on the health and well-being of the population. Energy supply from hydro-electric dams will decline.
Big Bill Coming
Among those welcoming the report is Manuel Pulgar, Peru's environment minister. He will play a leading part when the country’s capital, Lima, hosts the twentieth summit of the UN Framework Convention on Climate Change in Dec. 2014.
“Climate change is a global problem, but one that will multiply local and regional problems in unforeseeable ways," said Pulgar. "In Latin America, we have taken Amazonia and its seemingly limitless water and forests as a given. But recent unprecedented droughts have shown us just what happens when that water security falters ... ”
The report says the impacts of environmental degradation that have so far been felt in other parts of the world are now likely to be felt in Amazonia, threatening economic development and security.
Governments in the region, it says, need to recognize that development cannot continue without recognizing the damage caused to the water supply and the climate both globally and locally. Policy makers need scientists to monitor changes to conditions and the economic risks they pose.
Trillions of Tons of Water
These findings must be shared between academic institutions and governments so that they can decide how to remedy the problem. Annual reviews of dangerous hotspots are also needed, and cross-border groups of experts who could help both national and regional development plans to be worked out.
Carlos Klink, Brazil’s national secretary for climate change and environmental quality, endorsed these findings. “We are understanding more and more how interdependent water, food, energy and health security are across our continent."
“There is also interdependence between the countries that share the Amazon, which recycles trillions of tons of water that all our people and economies rely on," Klink continued. “The challenge that we are just beginning to recognize and act upon is one of transitioning to a more sustainable economy—one that values the role of a healthy Amazonia in underpinning long-term security and prosperity.”
Typhoon Molave is expected to make landfall in Vietnam on Wednesday with 90 mph winds and heavy rainfall that could lead to flooding and landslides, according to the U.S. Embassy and U.S. Consulate in Ho Chi Minh City. To prepare for the powerful storm that already tore through the Philippines, Vietnam is making plans to evacuate nearly 1.3 million people along the central coast, as Reuters reported.

A stretch of coastline in the Philippine capital, Manila has received backlash from environmentalists. The heavily polluted Manila Bay area, which had been slated for cleanup, has become the site of a controversial 500-meter (1,600-foot) stretch of white sand beach.
Sand Makeup Crucial for Ecosystems<p>While UNEP/GRID-Geneva generally supports finding <a href="https://www.dw.com/en/not-enough-sand-for-construction-industry-despite-abundance/a-49342942" target="_blank" rel="noopener noreferrer">alternative sources of sand</a> so as not to disrupt ecosystems in rivers and oceans when extracting them, Vander Velpen stressed it was vital to use sand which closely matches the makeup of the native sand to protect beach fauna.</p><p>"If you change the core characteristics of the native sand, the original sand, you need to do an environmental impact assessment (EIA) to find out how it's going to impact the ecosystem and nearby ecosystems," he told DW.</p><p>But according to Torres, such an assessment was not done in Manila.</p>
Beautification Stunt Instead of Proper Cleanup?<p>Manila Bay's waters are heavily polluted by oil and trash from nearby residential areas and ports. A huge "No swimming" sign warns visitors to stay away from the ocean.</p><p>Philippines' <a href="https://denr.gov.ph/index.php/priority-programs/manila-bay-clean-up/25-priority-programs/1825-frequently-ask-questions-faqs-on-the-dolomite-and-the-beach-nourishment-project" target="_blank">Department of Environment and Natural Resources (DENR)</a> has denied dolomite sand poses any risk to human health and the ecosystem.</p><p>However, scientists of the University of the Philippines have come forward disputing the DENR's claims. A <a href="https://biology.science.upd.edu.ph/index.php/ib-statement-regarding-dolomite-in-manila-bay/" target="_blank" rel="noopener noreferrer">statement by the Institute of Biology</a> said that using crushed dolomite did not address any of the rehabilitation phases and instead was "even more detrimental to the existing biodiversity as well as the communities in the area," pointing to the case of water birds. "The dumping of dolomite in Manila Bay has effectively covered part of the intertidal area used by the birds thereby reducing their habitat."</p><p>At peak migration season, Manila Bay is home to 90 aquatic bird species, including species of international conservation concern that are facing a very high extinction risk in the wild. </p><p>Authorities should focus on protecting and conserving biodiversity, the Institute of Biology added. "Rehabilitating mangroves is an example of a nature-based solution that is cheaper and more cost-effective than the dolomite dumping project," the scientists said.</p><p>Moreover, <a href="http://www.msi.upd.edu.ph/" target="_blank" rel="noopener noreferrer">the Marine Science Institute</a> has warned that prolonged inhalation of finer dust particles of dolomite could "cause chronic health effects," leading to discomfort in the chest, shortness of breath and coughing.</p><p>They also warned dolomite sand grains would erode during storms and be carried out to sea, essentially being washed away.</p>
Rehabilitation vs. Reclamation<p>Environmentalists say covering up the beach doesn't address the real issues of the bay. Torres and others believe the best way to clean up Manila Bay is not to add anything, but rather remove trash and pollution.</p><p>"There have been studies saying much of the waste comes from already collected waste — so these are open dump sites along the coast that get washed up because of the rain," Torres said.</p><p>She criticized the authorities for continuing to push reclamation projects she says are at odds with each other. These projects will affect large areas of mangrove forests, she said, and experts warn that this, in turn, exacerbates coastal erosion.</p><p>"If you've removed the areas that helped trap the sand, like mangrove forests, then the likelihood increases that you will have to nourish a beach. Same as building right up to the waterfront," said Vander Velpen of UNEP/GRID-Geneva.</p>
Plenty of Sand in the Sea?<p>The question of Manila's contentious white beach echoes larger questions about sand mining worldwide. <a href="https://unepgrid.ch/storage/app/media/documents/Sand_and_sustainability_UNEP_2019.pdf" target="_blank">Global sand consumption has tripled</a> over the past two decades, UNEP/GRID-Geneva has found. A huge chunk of it is now taken up by construction.</p><p>"Many operate on the assumption that natural sand is endless in its supply," said Vander Velpen.</p><p>Sand scarcity is a concern shared by Stefan Schimmels of <a href="https://www.fzk.uni-hannover.de/fzk_start.html?&L=1" target="_blank">Forschungszentrum Küste</a> who's done extensive research on shore nourishment to stop coastal erosion. And as climate change and rising sea levels are threatening coasts, demand for sand will grow even more.</p><p>A large study, the <a href="http://www.stencil-project.de/wp-content/uploads/2019/10/STENCIL_SWOT_Analyse_191026.pdf" target="_blank">Strategies and Tools for Environment-Friendly Shore Nourishments as Climate Change Impact Low-Regret Measures (STENCIL project)</a>, focused on the German island of Sylt, a popular vacation spot.</p><p>About 1 million cubic meter of sand per year is used to maintain the coastal area of Sylt, STENCIL project head Schimmels said. That's about 100 million 10-liter buckets of sand.</p><p>When sand was extracted off the coast of Sylt, underwater craters were formed. "You can still detect these craters even decades later," Schimmels told DW.</p><p>"Also when you add a couple of meters sand onto the beach — you essentially bury all things that do creep and fly," he said. "How quickly will they recover?" Schimmels said more research was needed as there was still too little known about long-term effects on the environment. </p>
Criticism Piling Up<p>As for Manila's artificial white sand, it looks like some might have already been blown away by a recent storm. DENR claims it wasn't washed away, but said that grayish sand, stones and other material had simply piled up over the dolomite sand. People in Manila have tweeted photos showing how the storm has ravaged the beach. </p>
