Why is lithium mining in Andean salt flats also called water mining?

By Víctor Quintanilla, David Cañas and Javier Oviedo* According to official figures, approximately 2.2 billion people worldwide lack access to drinking water.Despite this panorama, threats to this common good from overexploitation and pollution are increasing. One such threat is the accelerated extraction of lithium in Latin American countries, driven by corporate and state actors to meet the energy transition needs of the global North.Lithium extraction involves enormous water consumption and loss and is essentially water mining.On the continent, the advance of the lithium industry particularly threatens the salt flats and other Andean wetlands of the Gran Atacama region—located in the ecological region of the Puna, on the border of Argentina, Bolivia and Chile—where more than 53 percent of the mineral’s resources (potentially exploitable material) are located.Lithium mining exacerbates the natural water deficit in the area, threatening not only the salt flats, but also the many forms of life that live there. Where does the water used in lithium mining come from?First, it’s necessary to point out that salt flats are aquatic ecosystems located at the bottom of endorheic or closed basins. There, rivers do not flow into the sea but into the interior of the territory, so the water forms lakes or lagoons often accompanied by salt flats due to evaporation.In the salt flats, freshwater and saltwater usually coexist in a delicate balance that allows life to survive.The regions with salt flats, such as the Gran Atacama, are arid or semi-arid, with high evaporation and low rainfall. There we find freshwater aquifers at the foot of the mountains and brine aquifers in the center of the salt flats, both connected and in equilibrium.Brine is basically water with a high salt content, although the lithium mining industry considers it a mineral to justify its exploitation and minimize the water footprint of its activities.In addition to being essential for life, the waters of the salt flats are a heritage resource because they are very old—up to tens of thousands of years—and have been the livelihood of the indigenous people who have inhabited the Puna for thousands of years.When the mining industry moves into a salt flat, it threatens the natural balance and directly affects the relationship between water and the social environment, as well as the relationship between water and other forms of life.To extract lithium from a salt flat, the traditional procedure is to drill the salt flat, pour the brine into large ponds, wait for the water to evaporate so that the lithium concentration increases, send the lithium concentrate to an industrial plant and subject it to chemical treatment to separate the lithium from other salts and finally obtain lithium carbonate or hydroxide: a raw material used mainly in the manufacture of batteries.The continuous and large-scale extraction of brine from saline aquifers alters the natural balance of groundwater. As a result, areas that were previously filled with brine are emptied, causing freshwater from nearby aquifers to move in and occupy those spaces, becoming salinized in the process.The final processes to extract lithium carbonate and separate it from the rest of the compound also require water, which is drawn from surface or underground sources that also supply local communities.Therefore, the water used in lithium mining comes from:Underground freshwater and brine aquifers.Surface sources such as rivers and vegas (land where water accumulates). Therefore, the inherent risk of lithium mining is the overexploitation of these water sources. How much water does lithium mining use?The extraction of lithium by the methods described above involves an enormous consumption and loss of water, which is not returned to the environment because it completely used up, because its properties change, or because it is simply lost through evaporation.According to scientific data, the average water overconsumption in lithium mining is as follows:150 m3 of fresh water used to produce one ton of lithium.350 m3 of brine per ton of lithium.Between 100 and 1000 m3 of water evaporated per ton of lithium produced. To illustrate the loss of water resources in lithium mining, the water lost to evaporation is equivalent to the total water consumption of the population of Antofagasta (166,000 people) for two years. This Chilean city is located 200 km from the Salar de Atacama, where more than 90 percent of the country's lithium reserves are located.In addition to water depletion, lithium mining can also contaminate the resource by producing wastewater containing toxic substances. Our vital relationship with waterUnlike the mining industry, which sees water as just another resource to be exploited, the indigenous communities living in the area have an ancestral connection to the resource on which their economic and productive activities depend, as well as their customs, traditions and worldview.These communities must now confront the pressures on water from the advance of lithium mining, driven by outside interests.But they are doing so with courage, developing processes of defense of water and territory.Let us learn from them to defend a common good without which no way of life is possible.Learn more about the impacts of lithium mining on Andean salt flats in this StoryMap (in Spanish)Watch the recording of the webinar “Evidence of hyperconsumption of water in lithium extraction and production” (in Spanish) *Víctor Quintanilla is AIDA's Content Coordinator; David Cañas and Javier Oviedo are scientific advisors. 

Life in Andean wetlands at risk from extractivism

The expansion of industrial extraction of lithium and other minerals for the energy transition of the global north threatens wetlands in Argentina, Bolivia and Chile. These delicate ecosystems are an abundant source of life and fundamental for human subsistence, environmental balance and for mitigating and adapting to the climate crisis.The Andean wetlands - including salt flats, lakes and lagoons - of Argentina, Bolivia and Chile are at serious risk due to the advance of the extraction of lithium and other minerals demanded for the energy transition in the countries of the global north. The Andean Wetlands Alliance warns of this threat to these ecosystems where life abounds and which are key to human subsistence and biodiversity in general and to the fight against the climate crisis.This year, the Convention on Wetlands proposes as the theme for World Wetlands Day: “Protecting wetlands for our common future”. This theme highlights the importance of collective action to protect these ecosystems, on which the future of humanity depends.According to United Nations data, although they cover only 6% of the earth's surface, wetlands are home to 40% of all plant and animal species. And, worldwide, more than 1 billion people (one eighth of the Earth's population) live in rural and urban areas that depend on these ecosystems for their livelihoods. However, with a 35% global loss in the last 50 years (since 1970), wetlands are the most threatened ecosystem, disappearing three times faster than forests.In Latin America, the Andean wetlands of the Gran Atacama region - located in the border area of Argentina, Bolivia and Chile - are home to unique species of flora and fauna, especially adapted to extreme climatic conditions, as well as microorganisms that absorb carbon dioxide and release oxygen. Its high capacity to purify and store water guarantees the supply of the resource for communities and species, also generating conditions for adaptation to the climate crisis.However, due to the presence of large quantities of lithium in these wetlands - the three countries concentrate more than 53% of the resources (potentially exploitable material) of the mineral - there is great pressure on them: corporate and state actors have developed a growing and massive mining industry to meet the demand for lithium in the global north, oriented to the manufacture of electric vehicles and energy storage from renewable sources, among other purposes.On the other hand, national and provincial governments see the industry as an opportunity to attract investment and strengthen their economies, for which they relax or poorly implement regulations that require an adequate analysis of the environmental and social impacts of projects. Likewise, there are no processes of consultation and free, prior and informed consent with the indigenous communities living in the territories. Nor are the rights of access to information, citizen participation, access to justice in environmental matters, or a safe environment for environmental defenders guaranteed.One of the main impacts of this type of mining (lithium extraction) is on water, a central element of Andean wetlands. Lithium is extracted from the water beneath the salt flats, a process that requires both saltwater and freshwater. Andean wetlands exist in regions where survival depends on the scarce water that defines them. The expansion of extractivism in the Gran Atacama regionArgentinaAccording to official data, the country has a portfolio of more than 50 lithium projects in different stages of progress, mainly located in the provinces of Salta, Catamarca and Jujuy. Three of them are in production and export stage (a fourth project started production in July 2024), four are under construction and more than 40 are at different stages of progress (prospecting/exploration/feasibility), mostly in advanced exploration phase. In Salta and Jujuy operate large companies such as Pan American Energy, Pluspetrol and Tecpetrol, historically linked to the oil and gas industry, which are now expanding their presence in renewable energy sectors, with a marked interest in lithium extraction.However, through an amparo action filed against the authorities and government of the province of Jujuy, it has come to light that there are more than 40 mining projects in the Salinas Grandes Basin and Guayatayoc Lagoon alone, an endorheic basin where more than thirty native communities belonging to the Kolla and Atacama peoples/nations live. To date, their progress and whether there are other projects is unknown because access to public environmental information is restricted and is not provided in a complete and timely manner, in breach of national regulations and international standards. In the Salar del Hombre Muerto, Catamarca, is the oldest lithium mining enclave in the country. The salt flat has been exploited since 1996 by the company Livent (now Arcadium Lithium), causing the total and irreversible drying up of the vega of the Trapiche River. In March 2024, the Supreme Court of Catamarca ordered a halt to mining activity in this salar until a cumulative environmental impact assessment is conducted. BoliviaIn the Salar de Uyuni, the largest in the world, resources of 23 million tons of lithium have been identified. And there are 26 other salt flats that, by regulation, are reserved for the exploitation of the mineral; exploration activities are being carried out in six of them. In Bolivia, lithium is state-owned. The country has a state-owned exploitation plant that began operating in 2024 at 20% of its capacity. In 2012 and 2018, two public consultations were held for state-owned plants, but these excluded indigenous and native communities with titled collective lands. Some communities have informally denounced a significant depletion of springs and water wells. The degradation of the Salar de Chalviri and the overexploitation of lithium and boron in the Salar de Capina have also been denounced.Since 2023, agreements have been signed and exploration and camp installation activities have begun with one Russian and two Chinese companies. These agreements have resulted in two contracts, signed at the end of 2024 and pending approval by the Legislative Assembly, with the Russian company Uranium One Group for a plant in the Salar de Uyuni and with the Chinese consortium CBC Hong Kong (CATL-BRUMP-CMOC companies) for two other plants in the same salar. Also at the end of last year, a second international call was launched for the exploitation of four other salt flats (Empexa, Capina, Cañapa and Chiguana), which has resulted in the signing of agreements with the companies EAU Lithium Pty Ltd (Australia), Tecpetrol S.A. (Argentina) and Geolith Actaris (France). These agreements, contracts and processes have been developed without prior consultation processes and with a lack of transparency. ChileThe Salar de Atacama basin is home to more than 90% of Chile's lithium reserves and was one of the first to be exploited by the mining industry. Currently, there are four major mining operations in the Salar Atacama, located in the Antofagasta Region: lithium extraction by Sociedad Química y Minera de Chile (SQM) and Albemaerle, under contracts with the Corporación de Fomento de la Producción (CORFO), which involves the extraction of more than 2,000 liters of water per second; and the parallel extraction of copper by Minera Escondida and Minera Zaldívar, which extract more than 1,400 liters of fresh water per second, aggravating the already critical water crisis in the area. The Atacameño Community of Peine, who live in the salar basin, has taken legal action denouncing the overexploitation of their aquifers, while in Calama, citizen movements are demanding water governance in the face of uncontrolled extraction by mining companies. In 2015, a government-appointed committee recognized that brine extraction has adverse effects on the ecosystem, but instead of regulating its use, it confirmed the government's long-standing policy of regulating lithium production.In Chile, the government has exclusive property rights over lithium under Decree Law 2886 (1979). This means that state institutions, particularly CORFO, set the conditions under which private companies operate in the salars. In 1979, following U.S. directives, the Chilean government - the dictatorship of Augusto Pinochet - declared lithium a “strategic mineral” and took measures to safeguard long-term reserves by limiting production through quotas accredited by the Chilean Nuclear Energy Commission.The National Lithium Strategy, launched in 2023, seeks to expand state exploitation, including new projects in the Maricunga and Pedernales salt flats. Chile concentrates 36% of global lithium production and, with at least 31 new green hydrogen projects in the pipeline, pressure on water resources will increase exponentially. It is known that, since 2013, on SQM's property, 32.4% of the carob trees (Prosopis chilenis) have dried up due to lack of water. The carob tree is a native tree, resistant to drought and with very deep roots that allow it to survive in this environment.  Press contacts Víctor Quintanilla, Interamerican Association for Environmental Defense (AIDA), [email protected], +52 5570522107Rocío Wischñevsky, Fundación Ambiente y Recursos Naturales (FARN), Argentina, [email protected], +54 1159518538Verónica Gostissa, Asamblea Pucará (Argentina), [email protected], +54 93834771717Juan Donoso, Formando Rutas (Chile), [email protected], +4915780743628 

The international search for justice of the Mapuche communities in Mendoza, Argentina

In the context of a global climate crisis that has deepened existing inequalities in Latin America, Mapuche communities in Mendoza, Argentina, face multiple threats that increase their vulnerability to climate change and violate their rights.One of these activities is hydraulic fracturing, or fracking, a method of extracting hydrocarbons widely associated with socio-environmental impacts. In Argentina, it is widely used in the Vaca Muerta mega-development, which covers an area of about 30,000 square kilometers and is considered the second largest gas deposit and the fourth largest unconventional oil deposit in the world.A significant portion of Vaca Muerta is in Mendoza Province. The megaproject covers 8,700 square kilometers. Here, Mapuche communities also face a complex political environment that is threatening their territorial rights and even their identity. Added to this are national policies that are detrimental to indigenous rights in the country. These policies aim to dispossess the communities and make it easier to carry out fracking and other extractive activities.Faced with this situation, the Mapuche people are not willing to give up in the defense of their rights, their way of life and their territorial integrity.The Malalweche Territorial Identity Organization, which represents more than 20 Mapuche communities in the province of Mendoza, has appealed to various international organizations to denounce and publicize the critical situation and to demand justice.This process of international denunciation includes communications to the UN Special Rapporteurs on the Rights of Indigenous Peoples and on the Environment and Human Rights, and the submission of an amicus curiae brief to the Inter-American Court of Human Rights on climate emergency and human rights. Fracking's many impactsOil and gas extraction through fracking in Vaca Muerta takes place on the ancestral lands of the Mapuche people. Fracking is an extreme extraction technique that has significant environmental impacts, including increased greenhouse gas emissions. In the provinces of Neuquén and Río Negro, where the exploitation of Vaca Muerta is most widespread, serious environmental and human damage has been occurring for more than a decade and continues to increase.For Mapuche communities, the impact of fracking goes beyond physical damage to the environment. Extractive activities in their territories undermine their capacity for self-determination and profoundly affect their psychological and spiritual well-being, as their relationship with the land is fundamental to their identity and culture.Although fracking in Mendoza is in its infancy, with only a few active wells, the companies and the province have plans to expand it, in addition to the continued growth of activity throughout Vaca Muerta. In order to do this, they will need larger areas of land and the availability of large amounts of water. In this context, traditional practices such as transhumance – a type of seasonal migration in which shepherds move their animals between pastures at different times of the year – are seriously threatened.The growth of these activities, in the current context of water and climate crises in the region, increases the vulnerability of these communities and compromises their ability to continue living sustainably in their natural environment. Reduced human rights safeguardsThe strategy of expanding the occupation of Mapuche lands with mining and other extractive activities has led to the adoption of retrogressive policies that are undermining the framework for the protection of the rights of the Mapuche people in Mendoza and throughout the country.One of these is the declaration approved in March 2023 by the Chamber of Deputies of Mendoza, which questions the status of the Mapuche as an indigenous people of Argentina. This has raised concerns about the possibility of recognizing their territorial rights and the increase in evictions they are already suffering.Complementary measures that facilitate the development of extractive activities over the human rights of indigenous peoples are also being promoted at the national level. These include the closure by decree of the National Institute against Discrimination, Xenophobia and Racism, whose mission was to promote policies and actions aimed at achieving a society free of discrimination. This measure weakens the institutional protection of human rights.Similarly, the government announced the closure of the National Institute of Indigenous Affairs, dedicated to the promotion and defense of indigenous rights. Although this measure has not been carried out, its functional autonomy has been abolished and the areas dedicated to the recognition of communities and the regularization of their territories have been eliminated. In practice, these measures prevent these peoples from exercising their constitutional right to their ancestral lands.In addition, Law 26160, which had suspended the evictions of indigenous peoples while their territorial regularization was in process, has also been repealed. The Secretary of National Security, Patricia Bullrich, argued that there cannot be permanent laws preventing evictions, since "there cannot be a right to usurp.” Violent evictions against indigenous communities have already begun. Actions of international defenseIn response, the Mapuche communities of Mendoza have shown an enormous capacity for organization and resistance.They have turned to international bodies to expose their situation and demand concrete action from local and national authorities. A key example is the communications sent to the UN Rapporteurs on Indigenous Peoples and on Environment and Human Rights to denounce political persecution and violations of their territorial rights. These communications highlight the complacency of the authorities towards extractive interests. The focus of these denunciations has been the defense of their rights in the face of the advance of fracking and other extractive activities.Additionally, the communities were part of the advisory opinion process through which the Inter-American Court of Human Rights will clarify the continent's states' obligations to protect human rights in the face of the climate crisis.The Malalweche Organization submitted an amicus curiae brief, and its representative testified at a public hearing before the International Court of Justice to demonstrate that the extraction of hydrocarbons through fracking and metalliferous mining in their territories reduces their capacity to resist the climate crisis and exacerbates the severe water scarcity in the area, threatening their very survival.The Mapuche communities of Mendoza also presented concrete proposals for action. They called for their inclusion in all consultation and decision-making processes that affect their territories, in accordance with Convention 169 of the International Labor Organization. They stressed the importance of including their traditional wisdom in the development of public policies that benefit indigenous communities and contribute to more effective and sustainable solutions to global environmental challenges.They also called for the intervention of multilateral organizations to demand that the Argentine state guarantee free, prior and informed consultation and strengthen the national institutions responsible for protecting the rights of indigenous peoples.Supported by organizations that defend human rights and the environment, these struggles aim not only to protect the ancestral territories of the Mapuche, but also to guarantee their right to live in peace, with dignity, and in harmony with their natural environment. Their goal is to ensure the self-determination of indigenous peoples. This will allow them to manage their lands and resources in accordance with their worldview, which is deeply linked to conservation.Recognition of the rights of Mapuche communities, including the cessation of extractive activities such as fracking in their territories, is essential to protect their culture, health and livelihoods. With their ancestral wisdom, they offer a way to effectively address the climate crisis and build a more just and sustainable future.  

The ABCs of transition minerals and their role in energy production

By Mayela Sánchez, David Cañas and Javier Oviedo* There is no doubt that we need to move away from fossil fuels to address the climate crisis. But what does it mean to switch to other energy sources?To make a battery or a solar panel, raw materials from nature are also used.Some of these raw materials are minerals which, due to their characteristics and in the context of the energy transition, have been descriptively named transition minerals.What are these minerals, where are they found, and how are they used?Below we answer the most important questions about these mineral resources, because it is crucial to know which natural resources will supply the new energy sources, and to ensure that their extraction respects human rights and planetary limits, so that the energy transition is just. What are transition minerals and why are they called that?They are a group of minerals with a high capacity to store and conduct energy. Because of these properties, they are used in the development of renewable energy technologies, such as solar panels, batteries for electric mobility, or wind turbines.They are so called because they are considered essential for the technological development of renewable energy sources, such as those mentioned above. And in the context of the energy transition, energy sources that use these minerals are the most sought-after to replace fossil energy sources.Transition minerals are also often referred to as "critical" minerals because they are considered strategic to the energy transition. The term "critical" refers to elements that are vital to the economy and national security, but whose supply chain is vulnerable to disruption. This means that transition minerals may be strategic minerals, but not critical in terms of security and the economy.However, given the urgency of climate action, some states and international organizations have classified transition minerals as "critical" minerals in order to promote and facilitate access to these raw materials. What are the most important transition minerals?The most important transition minerals are cobalt, copper, graphite, lithium, nickel and rare earth.But there are at least 19 minerals used in various renewable energy technologies: bauxite, cadmium, cobalt, copper, chromium, tin, gallium, germanium, graphite, indium, lithium, manganese, molybdenum, nickel, selenium, silicon, tellurium, titanium, zinc, and the "rare" earth. What are "rare" earth elements and why are they so called?The "rare" earth elements are the 16 chemical elements of the lanthanoid or lanthanide group, plus Ithrium (Y), whose chemical behavior is virtually the same as that of the lanthanoids.They are Scandium, Ithrium, Lanthanum, Cerium, Praseodymium, Neodymium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Tullium, Iterbium and Lutetium.They are so called because when they were discovered in the 18th and 19th centuries, they were less well known than other elements considered similar, such as calcium. But the name is now outdated.Nor does the term "rare" refer to their abundance, because although they are not usually concentrated in deposits that can be exploited (so their mines are few), even the less abundant elements in this group are much more common than gold. What are transition minerals used for? What technologies are based on transition minerals?The uses of transition minerals in the technological development of renewable energy sources are diverse:Solar technologies: bauxite, cadmium, tin, germanium, gallium, indium, selenium, silicon, tellurium, zinc.Electrical installations: copper.Wind energy: bauxite, copper, chromium, manganese, molybdenum, rare earths, zinc.Energy storage: bauxite, cobalt, copper, graphite, lithium, manganese, molybdenum, nickel, rare earths, titanium.Batteries: cobalt, graphite, lithium, manganese, nickel, rare earths. In addition, they are used in a variety of modern technologies, for example in the manufacture of displays, cell phones, computer hard drives and LED lights, among others. Where are transition minerals found?The geography of transition minerals is broad, ranging from China to Canada, from the United States to Australia. But their extraction has been concentrated in countries of the global south.Several Latin American countries are among the top producers of various transition minerals. These materials are found in complex areas rich in biological and cultural diversity, such as the Amazon and the Andean wetlands.Argentina: lithiumBrazil: aluminum, bauxite, lithium, manganese, rare earths, titaniumBolivia: lithiumChile: copper, lithium, molybdenumColombia: nickelMexico: copper, tin, molybdenum, zincPeru: tin, molybdenum, zinc How do transition minerals support the energy transition and decarbonization?Transition minerals are seen as indispensable links in the energy transition to decarbonization, i.e. the shift away from fossil energy sources.But the global interest in these materials also raises questions about the benefits and challenges of mining transition minerals.The issue has become so relevant that last September, the United Nations Panel on Critical Minerals for Energy Transition issued a set of recommendations and principles to ensure equitable, fair and sustainable management of these minerals.In addition, as a result of the intensification and expansion of their extraction in countries of the region, the issue was brought before the Inter-American Commission on Human Rights for the first time on November 15.In a public hearing, representatives of communities and organizations from Argentina, Bolivia, Chile and Colombia, as well as regional organizations, presented information and testimonies on the environmental and social impacts of transition mineral mining.Given the current energy transition process, it is necessary to know where the resources that will enable the technologies to achieve this transition will come from.The extraction and use of transition minerals must avoid imposing disproportionate environmental and social costs on local communities and ecosystems. *Mayela Sánchez is a digital community specialist at AIDA; David Cañas and Javier Oviedo are scientific advisors.Sources consulted:-Olivera, B., Tornel, C., Azamar, A., Minerales críticos para la transición energética.

Organizations concerned by Mendoza Supreme Court rejecting their Participation while allowing that of the oil industry in litigation over fracking

The Mendoza Supreme Court’s differential treatment occurred in a lawsuit over the authorization of fracking, or hydraulic fracturing, for extracting oil and gas from the Vaca Muerta formation in the Argentinian province. Civil society groups express concern about the Mendoza Supreme Court’s refusal to receive information about the dangerous impacts of using fracking to extract oil and gas on indigenous peoples and the environment in Mendoza. The Court rejected the participation of seven organizations--including an organization of the Mapuche Indigenous People and both Argentinian and international groups on human rights and the environment--in a case that will impact the regulation of the oil and gas industry in Mendoza.The court has instead shown preference toward the fossil fuel industry, having allowed the participation of several groups representing the interests of oil companies in the same court case.The court is weighing a decision involving the authorization of hydraulic fracturing--also known as fracking--to extract oil and gas from the Vaca Muerta formation in Mendoza. Although fracking has not been widely used in Mendoza, the technique has caused public health and safety risks in other countries because of its impact on the environment.The organizations requested to participate in the case as "Friends of the Court" (amicus curiae). This is a common practice permitted in Mendoza and many countries around the world that allows people not otherwise connected with litigation to share information with the courts in cases that affect the public interest.One justice dissented from the Supreme Court's decision, criticizing that this ruling "is far from the level of listening that ought to demand the judge's attention in the resolution of cases of undoubted social interest, such as the one at issue here." Furthermore, the justice pointed out that "[t]he entities requesting this Court to grant them participation as amicus, have vast experience and specialization in environmental issues."So far, the Supreme Court has rejected the interventions of the following organizations: Organización Identidad Territorial Malalweche (Mendoza); Xumek (Mendoza); Centro de Estudios Legales y Sociales (national); the Interamerican Association for Environmental Defense (international), the Center for International Environmental Law (international); Earthjustice (international) and the Environmental Law Alliance Worldwide (international). Statements from the organizations Ana Laura Piccolo, executive director of XUMEK:"At Xumek, we are concerned by the provincial Supreme Court’s repeated rejections of the participation of civil society organizations through the figure of the 'Friend of the Court.' The organizations that have come forward to collaborate have established experience in the subject matter of the case and we make our contributions from a serious and objective perspective, in accordance with the technical and legal knowledge and expertise we possess. In addition, we have participated as amicus curiae in numerous judicial proceedings, both local and international".  Ñushpi Quilla Mayhuay Alancay, attorney in charge of the Indigenous Peoples Area of XUMEK:"As expressed in the dissenting vote, ignoring all the voices of civil society in a case of high social complexity affects the dialogue between the judiciary and the citizens, thereby weakening the democratic process in cases of social interest where the human rights of society can be affected". Erika Schmidhuber, attorney with the Center for Legal and Social Studies (CELS):"We consider it essential that the province complies with international human rights standards on free, prior and informed consultation with indigenous peoples for development projects in their ancestral territory, regardless of whether or not that territory is formally recognized. The Argentine State has already been condemned internationally for not complying with these standards. It is necessary for the Mendoza court to evaluate the arguments we have presented as they reflect the obligations that Mendoza must comply with." Jacob Kopas, attorney at Earthjustice:"Strong scientific evidence from other countries shows that fracking generates serious contamination risks, particularly by leeching toxic chemicals into nearby water supplies. It is essential that the Supreme Court of Mendoza take this evidence into consideration along with the support for fracking it has received from groups that profit from oil extraction." Sofía Barquero, attorney with AIDA's Ecosystems Program:"Our interest in this case stems from our desire to ensure that environmental protection and the rights of indigenous peoples are an integral part of any decision that may affect these communities. In that sense, we respectfully call on the Court to reconsider its decision and allow for the inclusion of civil society voices in this judicial process. We trust that the Court will take into consideration the importance of listening to all stakeholders in this case." Upasana Khatri, attorney at the Center for International Environmental Law (CIEL):"Fracking poses long-term environmental and health hazards that outlast production. It is essential that the Court hears from civil society experts on the evidence of such harms and the legal duty to prevent them - not just from industry actors with a stake in fossil fuel production - to ensure an informed decision on the risks and regulation of fracking in Mendoza."Press contactsOrganización Identidad Territorial Malalweche, Werken Gabriel Jofre, +54 2604592679XUMEK Asociación para la promoción y protección de los derechos humanos, Ñushpi Quilla Mayhuay Alancay, +54 9 2616807798CELS, Martina Noailles, [email protected], +54 9 11 6562-6566AIDA, Víctor Quintanilla, [email protected], +521 5570522107Earthjustice, Jacob Kopas, [email protected], +1 5862924603CIEL, Press Office, [email protected]
