Victory: Haven for leatherback sea turtles declared off-limits

In two separate rulings in May 2008, the Costa Rican government stood up for endangered leatherback sea turtles against business interests intent on building within their protected habitat.

A relative of dinosaurs, the endangered leatherback sea turtle has continually found its home in Costa Rica under threat. Poor planning and lack of oversight destroyed its nesting beaches in Flamingo and Tamarindo.

This time developers had their eye on the Leatherback National Marine Park (LNMP), home to some of the most important Leatherback nesting beaches in the Eastern Pacific Ocean.

A municipal zoning regulation was enacted that would authorize construction in part of the LNMP. However, AIDA and its local partner CEDARENA, together with the Leatherback Trust, successfully defended the park.

The Constitutional Chamber of the Costa Rican Supreme Court nullified the municipal zoning regulation, safeguarding the Leatherback sea turtles and their nesting beaches. This ruling closely followed another court victory by AIDA, CEDARENA, and Justice for Nature that required the government to expropriate the private lands within the LNMP, otherwise destined to be tourist playgrounds.

The leatherback sea turtle will continue to face threats from tourism development, fishing, egg poaching, and pollution. However, AIDA and its partners have shown that the law can be used to make a powerful difference.

Changing the way we approach large dams

Cigarettes once served to cure cough; lead-based makeup was fashionable; and DDT, a highly toxic insecticide, was used in gardens where children played. At the time, little was known of their grave impacts on health and the environment. These facts may shock us now, but once they were normal. Cigarettes, lead, and DDT were widely believed to be more beneficial than harmful to humanity. Thanks to science, we learned of their serious health and environmental impacts. We’re learning the same now about large dams. A photograph of a dam surrounded by trees is as misleading as the doctor-approved cigarette ads once were. In the last decade, we’ve seen that the damage dams do to communities and ecosystems is far greater than the benefits they provide. Recently, an academic study confirmed something even more worrying: large dams aggravate climate change. At the end of 2016, researchers from Washington State University (WSU) concluded that reservoirs around the world, not just those in tropical areas, generate 1.3 percent of the total greenhouse gases produced by mankind. Dams, they found, are an “underestimated” source of contaminating emissions, particularly methane, a pollutant 34 times more effective at trapping heat than carbon dioxide. These findings have not yet been properly absorbed. Large dams continue to be funded and promoted as clean energy. Some countries boast nearly 100 percent renewable energy, yet reports show that at least half of that is hydroelectric energy, produced primarily by large dams. Violating human rights Even before WSU’s study was made public, the damage large dams do to communities and the environment was well documented. Dams disrupt traditional lifestyles, and affected communities are forced to adapt to new environmental conditions, such as altered river flow and species migration. Many communities have also been victims of forced displacement and fall into poverty as a result. In the Brazilian Amazon, the Belo Monte Dam provides a prime example of the ways dams cause negative impacts on both people and the environment. At AIDA, we’ve worked hand-in-hand with the indigenous and river communities of the Xingu River Basin, who have seen the trees fall around them, the red earth spread like a stain across their forest, the fish disappear from their rivers, and their small islands submerged. For those living in Altamira, the city nearest the dam, living conditions also worsened significantly, with increased violence, substance abuse, and prostitution. This story has been repeated thousands of times around the world. According to International Rivers, 57 thousand large dams had been built by 2015, disrupting more than half of the world’s rivers and causing the displacement of at least 40 million people. What can we do? Although the WSU study may surprise governments and corporations that promote the construction of large dams, for the health of the planet the trend must be stopped. Environmentally friendly alternatives exist, which do not imply the same social, economic and climatic impacts as dams. Hope can be found in the Brazilian Amazon with the Munduruku tribe. Last year, their long fight paid off with the cancellation of a large dam project on the Tapajós River, the sacred waterway on which their lifestyle depends. The decision to cancel the dam was backed with evidence of the impacts dams have on communities and ecosystems, exemplified by the case of Belo Monte. Recently, the Munduruku gathered to discuss and find solutions for the threats they continue to face as development rages in the Amazon. Solutions include the decentralization of energy sources, the promotion of small-scale projects, and solar and geothermal energy, all of which must be accompanied by adequate community-consultation processes. But they must be studied on a case-by-case basis and according to available resources, as what’s best for one community may not be best for another. Funding must carefully evaluate which projects to support, analyzing in detail the potential socio-environmental impacts. It may sound like people are making all the wrong decisions, but now is no time to be discouraged. We have the scientific information we need to care for our planet. Societal changes prove that we can change our actions to prioritize our health. Why can’t we do the same for the health of our planet? In the last several decades, the number of smokers has drastically decreased, we’ve stopped lacing makeup and other products with lead, and DDT has been regulated. In terms of large dams, the solution lies in re-thinking the way we produce energy and prioritizing the preservation of our free-flowing rivers.

Letter to Green Climate Fund Board and Advisors: Concern regarding the use of GCF resources to support large hydropower

We write to express our concern regarding the use of GCF resources to support large hydropower in general, and in particular the following proposals in the GCF pipeline: Qairokkum Hydropower Rehabilitation, Tajikistan Upper Trishuli-1, Nepal Tina River Hydro Project, Solomon Islands Large hydropower is a non-innovative, last-century technology with dubious climate mitigation benefits and a long track record of exceedingly high financial, environmental, and social costs. Supporting such proposals would not be consistent with the Fund’s goal, to promote a paradigm shift toward lowemission, climate resilient development, in the context of sustainable development. Further, large hydropower projects would not meet the GCF’s selection criteria related to impact, paradigm shift potential, sustainable development, and efficiency and effectiveness. The reasons why the GCF should not support large hydropower are described in the annex, and briefly summarized here: Large dams are vulnerable to climate change: more frequent droughts make them inefficient and increased rainfall reduces their lifespan. Large dams exacerbate climate change: considerable amounts of greenhouse gasses, notably methane (30 times more potent than CO2), are emitted from reservoirs; and their construction damages carbon sinks, including forests and rivers. Large dams harm biodiversity, which in turn impairs communities’ capacity to adapt to a changing climate. Large dams can negatively affect local communities by impoverishing them, breaking social networks, and negatively affecting livelihoods and cultures. Large dams can become dangerous: climate change-related extreme weather events and earthquakes can cause dams to fail, jeopardizing lives and property downstream. Large dams are not economical and are ill suited to address urgent energy needs: recent studies clearly demonstrate that large dams typically suffer significant cost and time overruns. Better energy options are widely available and the GCF should play a fundamental role in promoting them.
