Preserving Bolivia’s High-Andean lakes, sources of life
Located at 13,000 feet above sea level, in the high plateau of the Bolivian Andes, the Poopó and Uru Uru lakes are a source of life for indigenous and rural communities. Part of the water system of Lake Titicaca, they’re recognized as Wetlands of International Importance under the Ramsar Convention.
The Poopó and Uru Uru lake basin is also an important host of rich local biodiversity. During the winter season, the lakes are home to the largest concentration of flamingos in the high Andean region of South America. Approximately 200 species of animals and plants have been recorded there, including rare endemic and migratory birds.
But the health of these lakes is in critical condition. In just a few years, the water levels of Lake Poopó shrunk to alarming levels, before completely disappearing in 2015. Although Poopó is slowly recovering thanks to seasonal rains, it remains vulnerable in the dry season.
The serious environmental degradation of the lakes is the result of human activities that affect the quantity and quality of its waters, including the diversion of rivers, the climate crisis and mining activities.
Damages to these ecosystems put at risk the life systems that depend on them, including the subsistence of Aymara and Quechua communities, and the Uru Murato, one of Bolivia’s oldest native nations. The Uru Murato people were fishermen, but due to the contamination and reduction of the waters, they have been forced to migrate to work in the salt mines.

Championing Lake Poopó’s recovery to protect the life it holds
Calixta Mamani thinks with nostalgia of the tall, green cattails growing along the shores of Lake Poopó, in the arid central plateau of the Bolivian Andes. She once used the reeds as feed for her livestock. "Now, everything has dried up,” she reflected. “There is no life here, the land no longer produces." She thinks also of the birds—Titicaca grebes and Andean flamingos—and of the fish that were once so abundant in the area. "Now you don't see them anymore,” she lamented. “Everything, our culture, is gone." The losses described by Calixta represent a plundering. The indigenous and rural communities living near Lake Poopó have been deprived, not only of their primary water source, but of their livelihood, their way of life, and their culture. Bolivia's second largest lake, Poopó has been damaged by the diversion of rivers, the climate crisis, and mining activities—which have continued despite the pandemic—to the point of putting at risk all the life systems that depend on it. Calixta is a member of the National Network of Women in Defense of Mother Earth (RENAMAT), an organization that defends the rights of indigenous and peasant women against the destructive impacts of extractive industries in the regions of Oruro, La Paz, and Potosí. Responsible for grazing the animals, food preparation, and other household tasks, Calixta and other local women live with the lake on a daily basis. As a result, they more acutely suffer the effects of its degradation. It’s because of the respectful relationship they have with Mother Earth and Mother Water that the communities around Lake Poopó are fighting to save it. Decades of Pollution According to a report by the Collective for the Coordination of Socio-Environmental Actions (Colectivo CASA), complaints related to Lake Poopó’s contamination by mining activities date back to 1981, when researchers revealed that 120 lead, tin, and gold mines were discharging their waste directly into its waters. The situation, which has continued over the years, has led to sedimentation. This means that considerable amounts of cadmium, zinc, arsenic, and lead have become sediment in the lake, making its waters unsuitable for human and animal consumption and of limited use for crop irrigation. "With the passage of time and the advance of mining, the exploitation of minerals has intensified,” said Petrona Lima, from Ayllu San Agustín de Puñaca, municipality of Poopó, in a testimony collected by the Center for Andean Communication and Development (CENDA). “Little by little all this has been disappearing, water veins have been cut, and everything has come to be as it is now; it looks like everything is burned." In an effort to preserve its biodiversity—which includes endemic and migratory birds and the largest number of flamingos in the Bolivian highlands—in 2002 Lake Poopó, along with Lake Uru Uru, was declared a Wetland of International Importance under the Ramsar Convention. Despite this protection, the ecosystem remains in serious danger. In December 2015, water levels in Poopó reduced to such an extent that the body of water actually disappeared—an event considered one of Bolivia’s greatest environmental catastrophes. Although the lake managed to recover its flow during the rainy season, the situation remains critical in the dry months. The Climate Crisis and River Diversion The degradation of the lake is also a result of the global climate crisis, which brings intense droughts and increased temperatures. If the global average temperature increased by 0.8°C due to climate change, in Lake Poopó the increase was 2.5°C, according to information published in 2015, accelerating the evaporation of its waters. Another major source of the degradation of these high-Andean lakes is the diversion of two of the rivers that feed it: the Desaguadero and Mauri rivers. The former has decreased due to mining and agricultural operations, while the later, located on the border with Peru, has been diverted. Currently threatening the Poopó Basin is the implementation of the second phase of a canal project that would divert more than 500 liters of water per second from the Mauri River to feed the agro-industry in Tacna, Peru. The implementation of the project’s first phase was one of the primary causes of the lake’s disappearance in 2015. Defending Their Source of Life Rural communities, the Aymara and Quechua peoples, the Uru Murato—among Bolivia’s oldest native nations—all depend on the Poopó and Uru Uru lakes. The Uru Murato used to live from fishing, but the contamination of Poopó has forced them to migrate to work in the salt mines. In addition to causing serious environmental damages, what’s happening to this ecosystem is a serious violation of affected peoples’ rights to water, health, territory, food, and work. That’s why AIDA and local organizations have joined forces to defend Lake Poopó, its biodiversity, and the communities that depend on it. In July of last year, we asked the Ramsar Convention Secretariat to send a mission of experts to the country to assess the health of Lakes Poopó and Uru Uru and make recommendations to the government for their recovery. This month, we launched the campaign #LagoPoopóEsVida to make the situation visible and to draw the attention of national and international authorities to the risks facing the lakes and its people. Protecting Lake Poopó would be tantamount to saving lives and preserving one of Bolivia’s cultural cornerstones.

Communities request international support to save Bolivia’s Poopó and Uru Uru lakes
Local communities and organizations call on the Ramsar Convention to visit the lakes and issue recommendations for their preservation. The lakes are at grave risk from mining, river diversion and the climate crisis, threatening the subsistence of indigenous communities and the region’s unique plant and animal species. La Paz, Bolivia. Local communities along with a coalition of organizations request that the Ramsar Convention, an intergovernmental treaty for the protection of wetlands, send an expert mission to evaluate the health of lakes Poopó and Uru Uru, and issue recommendations to the Bolivian government for the urgent recovery of these key ecosystems. “The Ramsar Convention’s specialized knowledge on wetlands can be of great use to save lakes Poopó and Uru Uru,” said Carlos Lozano Acosta, senior attorney with the Interamerican Association for Environmental Defense (AIDA). These lakes are an important source of water for the plants and animals of the Central-Eastern Bolivian highlands, particularly for several endemic and migratory bird species. Lake Poopó is the second largest lake in Bolivia, after the iconic Lake Titicaca. Together, the lakes host the largest number of flamingos in the Bolivian highlands and, quite possibly, in the entire high Andean region of South America. These highland ecosystems are also home to unique species such as the Titicaca grebe (Rollandia microptera), an endangered species of flightless bird. The lives and livelihoods of peasant and indigenous populations—including Quechua, Aymara, and Uru Murato communities—depend on the preservation of lakes Poopó and Uru Uru. The Uru Murato are known as the “people of water” due to their dependence on the lakes, and are among the oldest native indigenous communities in Bolivia. “It was precisely to preserve the lakes that, in 2002, the government registered Poopó and Uru Uru as wetlands of international importance under the Ramsar Convention,” explained Sergio Vásquez, director of the Andean Communication and Development Center (CENDA). “As such, we ask that Ramsar support the Bolivian government in the protection of these and other high Andean wetlands.” In December 2015, the water levels of Lake Poopó were reduced to such a degree that the body of water actually disappeared, in what is now considered one of the largest environmental catastrophes in the country. The causes were various: sedimentation produced by mining activity; the diversion of the lake’s tributary rivers; and natural phenomenon aggravated by the climate crisis. Although the lake’s levels have since increased in times of rain, the situation remains critical during the dry season. “We’re requesting that Ramsar experts identify measures to strengthen the surveillance and monitoring of these ecosystems,” said Angela Cuenca, of the Coordinated Collective for Socio-Environmental Actions (CASA Collective). “We’d also like them to recommend mitigation and restoration actions for the damages caused by mining activities.” The degradation of lakes Poopó and Uru Uru directly affects the wellbeing of the people who depend on them, causing harms to public health, particularly among women, girls and boys. The grave situation of the lakes forced the Uru Murato people, previously dedicated to fishing, to migrate for work in the mines, placing them among the region’s first climate refugees. “We indigenous and rural women live and feel the effects of pollution and the lake’s disappearance, because we are responsible for feeding and sustaining our families,” explained Margarita Aquino, from the National Network of Women Defenders of Mother Earth (RENAMAT). “These water sources are vital for our communities and for Mother Earth Press contact: Victor Quintanilla (Mexico), AIDA, [email protected], +5215570522107
