Conserving the Ciénaga Grande de Santa Marta

Ciénaga Grande de Santa Marta, the largest and most productive coastal wetland in Colombia, covers 45,000 hectares. At the confluence of the Magdalena River and the Caribbean Sea, the site boasts an immense variety of flora and fauna, including mammals, birds and fish. Its southern tip is a beautiful sanctuary of mangroves, swamp and amphibious forest.

On the calm waters of the marsh stand the Ciénaga’s famous stilt villages, supported by pillars or simple wooden stakes and inhabited by local fishermen since 1800. In a place accessible only by water, many of the things we take for granted—being served a glass of water, quick access to a doctor—are considered luxuries. Residents depend on the natural world around them. Sadly, in recent years mass fish die-offs caused by the marsh’s degradation have threatened the livelihoods of 2,500 people who call the Ciénaga Grande home.

Illegal activities are destroying this vital ecosystem: intentionally set forest fires, deforestation of large tracks of land for agriculture and livestock, logging and burning of mangroves, and 27 kilometers of illegally built dikes.

This destruction not only devastates the local fishery; it also has global impact. Ciénaga Grande’s mangroves absorb large quantities of carbon dioxide from the atmosphere, aiding in the global fight against climate change.

The importance of the Ciénaga Grande has been recognized both nationally – the Sanctuary of Flora and Fauna Ciénaga Grande de Santa Marta is a national park – and internationally: UNESCO’s Man and the Biosphere program declared the lagoon a biosphere reserve; and the Ciénaga Grande is listed as a Wetland of International Importance under the Ramsar Convention, an intergovernmental treaty for the protection of wetlands.

AIDA and our partners are advocating for the Colombian government to fulfill its national and international obligations to protect the Ciénaga Grande. After all, millions of animals, the local community, and our global climate depend on it.  

 


Lives of no return: Stories behind the construction of Belo Monte

By María José Veramendi Villa, senior attorney, AIDA, @MaJoVeramendi  When you start the descent by plane to the city of Altamira in Pará, Brazil, the darkness of the night is interrupted by the bright lights of worksites a few kilometers outside the city where construction of the Belo Monte dam is underway. That’s when things turn bleak. On a recent trip to the area I was able to see how the situation of thousands of residents – the indigenous, riverine and city dwellers of Altamira - continues to deteriorate. Their communities and livelihoods are being irreversibly affected and their human rights systematically violated by the construction of the hydropower plant. When night becomes day From the plane, the lights from the worksites are just momentary flashes. But for the indigenous and riverine communities closest to them, those lights have brought a radical change to their lifestyles. José Alexandre lives with his family in Arroz Cru, a waterfront community located on the left bank of the Volta Grande, or Big Bend, of the Xingu River in the municipality of Vitória do Xingu. The community is in front of the Pimental worksite. His entire life has been spent in the area, where hunting and fishing are major activities. But everything changed when construction of the dam started.

Large Dams

The link between international environmental law, human rights and large dams

The article is an update and reissue of two chapters of the report Large Dams in the Americas: Is the Cure Worse than the Disease, written by Jacob Kopas and Astrid Puentes Riaño. The article identifies “the main obligations, standards, decisions and international law applicable to large hydropower plants that our governments should use in the planning, implementation, operation and closure of these projects."   The article is divided into two parts. Chapter I offers an overview of the main standards, the legal framework of international human rights and environmental law as well as the decisions and international jurisprudence applicable to the cases of large dams. In Chapter II, this framework is applied to the cases of human rights abuses caused by the degradation of the environment through the development of a large dam.

Toxic Pollution, Climate Change

Short-Lived Climate Pollutants: A great opportunity to put the brakes on climate change

By Florencia Ortuzar, legal advisor, AIDA While many of us are alarmed by climate change and its already tangible effects, concern becomes even greater when learning the fact that all the CO2  accumulated in the atmosphere cannot be removed, even if we were to shut down all the sources of emissions today. This reality was confirmed in the Fifth Assessment Report on the state of the climate, issued by the Intergovernmental Panel on Climate Change (IPCC). The explanation for this is simple: CO2, in contrast to other gases and pollutants, remains in the atmosphere for millennia after being released. It is stuck in the atmosphere for what is eternal for human standards, implying that its greenhouse effect does not end even with an immediate halt in emissions. The good news is that CO2 is not the only cause of global warming. There are other pollutants that, unlike CO2, only stay in the atmosphere for a relatively short time. These “other” agents are responsible for 40-45% of global warming, and they remain in the atmosphere for a minimum of a few hours to a maximum of a few decades. They are called short-lived climate pollutants, or SLCPs. Like CO2, SLCP emissions have a negative impact on humans and ecosystems. So a reduction in these pollutants would bring immediate relief to the worst affected by climate change and would bring important benefits to the environment and people. The main SLCPs  Although all SLCPs contribute significantly to climate change and share the trait of being short-lived, each has its unique characteristics and emission sources.  Black carbon or soot, is a particulate substance produced by the incomplete combustion of fossil fuels, mainly from motor vehicles, domestic stoves, fires and factories. The dark particles heat the atmosphere as they absorb light, and when the particles land on snow and ice they accelerate melting. Black carbon also affects human health by causing respiratory problems such as lung cancer and asthma.  Tropospheric ozone is a gas formed by the reaction of the sun with other gases called "precursors," which can be man made or naturally occurring. One of these precursors is methane, another SLCP. Tropospheric ozone is associated with diseases including bronchitis, emphysema, asthma and permanent scarring of the lung tissue. Studies also show that this gas has a direct impact on vegetation, reducing crop yields and the ability of plants to absorb CO2. Methane is a powerful greenhouse gas, and 60% of its emissions come from human activities like rice farming, coal mining, landfill and oil combustion. Two important sources of methane include cattle farming, whose effect has dangerously increased with industrial meat production (Spanish), and large dams, especially those in tropical areas.  Hydrofluorocarbons (HFCs) are man-made gases used in the production of air conditioners, refrigerators and aerosols. They have replaced chlorofluorocarbons (CFCs), which were banned under the Montreal Protocol. Although HFCs represent a small proportion of the greenhouse gases emitted into the atmosphere, their use is growing at an alarming speed of an average of 10-15% each year, according to a United Nations Environment Programme (UNEP) report.   Everyone wins According to the IPCC, the reduction of these pollutants could avert a rise in average global temperatures by approximately 0.5 degrees Celsius by 2050, cutting the current rate of global warming in half and helping to protect some of the areas most susceptible to climate change like the Arctic, the high Himalayan regions and Tibet. The mitigation of SLCPs is also crucial for decelerating glacial melting and rising sea levels, a serious situation for the world’s population that lives in coastal areas. The reduction of SLCPs would also bring important socio-environmental benefits. Black carbon and tropospheric ozone harm human health and reduce crop yields. This in turn affects ecosystems, food security, human welfare and the entire natural cycle that keeps the planet healthy. Some talking points Given that SLCPs stem from different sources, effective mitigation requires a series of comprehensive actions that deal with each pollutant separately. Fortunately, the road is already laid out. Many of the technologies, laws and institutions needed to cut SLCP emissions already exist. In the case of black carbon, new technologies are inexpensive and available. Developed countries have already reduced emissions significantly through the use of green technologies. Ideas include the modernization of domestic cooking systems in the region, introducing the use of solar cookers and new transport systems with improved exhaust filters to reduce greenhouse gas emissions.   The amount of methane in the atmosphere, which affects the level of tropospheric ozone, is largely dependent on industrial activities. To reduce emissions, effective regulations should be implemented to control the industries that emit the most methane, including intensive cattle farming, mining, hydrocarbons and large dams. For HFCs, an alternative already exists. There need to be regulations that encourage people to substitute HFCs for greener alternatives, no matter the commercial barriers. Some countries have proposed incorporating HFCs in the Montreal Protocol, an international agreement recognized as one of the most successful initiatives to significantly and rapidly reduce CFC emissions, addressing a similar challenge, to the one we face today. To find out more about SLCPs, you can read a briefing paper (Spanish) put together by AIDA, CEDHA, CEMDA and RedRacc.
