7 AIDA Advances of 2020

It was a year unlike any other. This new reality makes our victories and daily accomplishments all the more sweet. So we’re especially proud to report on the progress we've made toward a healthy environment and climate justice in Latin America. 1. Safeguarding the High Seas More than 99% of the global high seas—waters beyond national jurisdiction—are unprotected. To remedy this, over the past year we have led Latin American representation in the High Seas Alliance, collaborating with governments to negotiate an ambitious United Nations treaty to protect these waters and key migratory species of sharks, whales, turtles and tuna. The high seas are both essential to long-term ocean health and a critical carbon sink that helps mitigate climate change.   2. Influencing Divestment in the Amazon For nearly a decade we have worked to halt Brazil’s Belo Monte dam, which has displaced thousands of indigenous people and devastated hundreds of rare species. This year, our testimony led the Norwegian Pension Fund, the world's largest state-owned fund, to exclude one of the dam’s main financers, Eletrobras, from its portfolio because of environmental and human rights violations caused by the dam. This is a notable step toward justice for affected communities. 3. Defending Páramos from Mining We continued to protect páramos in Colombia and Ecuador from mining. These biodiverse, high-altitude forests and wetlands are critical carbon sinks that also provide fresh water for millions of people and habitat for endangered species. Our team contributed legal and technical expertise, and, in the case of Santurbán in Colombia, helped build capacity among local attorneys who are now leading the lawsuit to protect this páramo. 4. Protecting Environmental Defenders Latin America is the most dangerous region in the world for environmental defenders. This year, AIDA brought together more than 70 prominent environment defenders from 14 countries across Latin America to share current information about risks and effective strategies for defense. Participants discussed their challenges, identified gaps in knowledge, and developed new approaches for protecting themselves and their territories. 5. Halting Extractive Energy Development Our ongoing legal and technical expertise was critical to halting fossil fuel expansion. We continued litigation to uphold the moratorium on fracking and, helped prevent further coal mining expansion in Colombia, supported communities in Chile affected by coal power plants, and led efforts to hold International Financial Institutions accountable for funding harmful hydropower Guatemala and Colombia. This work is key to promoting the just transition toward truly clean energy. 6. Preserving Marine Biodiversity in Patagonia The Chilean Magallanes region is home to some of the largest whales and dolphins and one of the most pristine areas on our planet. The greatest environmental threat for this region is the salmon farming industry. Building on our past work, we used the law to halt expanded salmon farming and expose the harms the industry brings. Our work closed one salmon farm and set a precedent for the closure of seven others, all of which are under review by Chilean courts. 7. Strengthening Indigenous Land Management in Colombia In coalition with four indigenous communities of the Sierra Nevada de Santa Marta, we continued protecting their lands from illegal mining. Facing hundreds of proposed projects, we helped implement legal strategies demanding a new territorial management plan that recognizes the traditional governing authority of the indigenous. We also helped strengthen community capacity through workshops on environmental protection.  

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.

Mexico’s Federal Mining Law threatens human rights of indigenous peoples

International civil society organizations submitted amicus curiae briefs to the Mexican Supreme Court in support of the State of Puebla-based Masewal people’s constitutional action.Groups also delivered to the Court’s Second Chamber more than 4,000 signatures supporting the defense of indigenous people’s rights, collected through www.change.org.mx International civil society organizations are supporting a lawsuit filed by the Masewal indigenous people of Cuetzalan del Progreso, based in the Sierra Norte of the Mexican state of Puebla, against Mexico’s Mining Law. The Masewal request that the Supreme Court of Justice of the Nation (SCJN) declare the law unconstitutional because it violates indigenous peoples’ fundamental rights. Earthjustice, the Environmental Defender Law Center (EDLC) and the Interamerican Association for Environmental Defense (AIDA) filed separate amicus curiae (“friend of the court”) briefs to provide information in order to help the SCJN rule on litigation initiated by the Altepetajpianij Maseual Council and the Mexican Center for Environmental Law (CEMDA). The constitutional suit, originally filed in March 2015, argues that Mexico adopted the new Mining Law in violation of indigenous rights by not previously consulting or informing indigenous peoples before passing the law. As a result, the law failed to take into account indigenous values or perspectives and contained no mechanism to protect their human rights, even though many mining concessions already affect their territories. Above all, this law violates indigenous peoples’ rights to self-determination by excluding them from decision-making on mining within their territories, thus threatening local communities’ quality of life. “As the First Peoples, we are convinced that, in order to have a good life –Yeknemilis, as we say in Nahuatl– it is necessary that we be well and have social peace. And we cannot be well, nor can we build social peace in our territories, when extractive projects such as destructive mining threaten our way of life,” the Masewal people told SCJN justices in their brief. “Our contribution presented in our amicus brief highlights that Mexico’s international obligations require free, prior, and informed consultations with indigenous peoples before approving any legislative measure that affects them, especially when it comes to their territorial rights,” said Guillermo Zúñiga, Earthjustice international attorney.  “This also includes laws on the extraction of natural resources found in their territories, which applies directly to the case of the Mining Law.” “Mining concessions cannot be granted solely based on mining legislation. A higher-level legal framework, based on human rights and environmental law, and on the interrelation between the two issues, is must be applied in this case. This broader, legal framework determines and limits the granting of mining titles in the case of lands and territories,” says EDLC in its amicus’ conclusions. "Mexico’s Supreme Court of Justice of the Nation has the opportunity to set an exemplary precedent for the region with respect to the protection of indigenous rights," said attorney Carlos Lozano Acosta of AIDA. "In turn, the SCJN can learn from regional experience, adopting the relevant standards that courts in other countries have provided in favor of indigenous peoples, as evidenced in our amicus brief." Letters of support from other indigenous groups in Mexico, Colombia, Brazil, Bolivia, and Guatemala, as well as 4,091 signatures collected through the platform change.org.mx as of June 26, were sent to the Ministers of the SCJN’s Second Chamber supporting the Masewal People's suit. press contacts Ricardo Ruiz (Mexico), CEMDA, 5559644162, [email protected] Victor Quintanilla (Mexico), AIDA, 5570522107, [email protected] Robert Valencia (US), Earthjustice, [email protected]  

Belo Sun project puts Amazon at serious risk of contamination

The Canadian company developing Belo Sun is failing to take sufficient measures to prevent a planned gold mine from contaminating groundwater and surface water sources. The company also plans to use large quantities of cyanide, a substance highly dangerous to the health of people and ecosystems. Altamira, Brazil. A technical evaluation concluded that a gold mine planned for the Volta Grande of the Xingu River, deep in the Brazilian Amazon, risks contaminating water sources and harming the area’s indigenous and riverine communities. A project of the Canadian company Belo Sun Mining Corp., the mine could leech contaminating fluids, and would employ high quantities of cyanide, as well as other chemical processes that could, unless properly implemented, cause acidic waste to reach aquifers and rivers. The analysis prepared by Andrés Ángel, geologist and scientific advisor to the Interamerican Association for Environmental Defense (AIDA), found inconsistencies in the information the company has published in the environmental licensing process. In the 2015 feasibility report presented to the project's investors, Ángel found that the company stated that the area’s soil and shallow rocks are impermeable, that is, contaminants cannot seep through them. However, in 2012 and 2016 environmental impact studies, Belo Sun shows the regulatory authorities data, descriptions and analyses that contradict what was said in 2015, going so far as to say that the aforementioned soils and rocks behave like porous or fractured aquifers. In recent studies, the general design of the project and the management measures proposed by the company, which do not even include installing liners to prevent leaching under certain structures, are insufficient to reduce the risk of surface and groundwater contamination, the expert explained. The evaluation also warns of the use of large quantities of cyanide as the method of choice for the separation of gold. It’s expected that between 330 and 390 grams per ton of processed material will be used, out of an estimated total of 116 million tons of ore. "Less polluting and dangerous alternatives exist, including the export of polymetallic concentrates where the separation of material of economic interest occurs later. In the Amazon rainforest, it would be essential to consider this option" says Ángel. The report also highlights that cyanide can be lethal even in very low doses for both aquatic fauna and people, and points out the risks of transporting this substance through low quality road and fluvial infrastructure. Another serious risk highlighted by the study is the generation of acid drainage as a result of the chemical process planned by the company to eliminate the cyanide used, and as a cumulative impact after the project's lifetime, taking into account that some units were classified as having moderate acid generation potential. Although an active treatment (the addition of lime to effluents) is proposed for this purpose, such a measure implies greater demand for reagents and, therefore, greater total environmental impacts. Finally, Ángel highlighted the lack of information on the synergistic impacts between the Belo Monte Dam—which already affects the area—and the downstream mining project in the reduced flow section of the Xingu River, which in turn will determine the type and extent of the mine's risks in the event of serious failures. The Brazilian justice system suspended Belo Sun’s installation license in 2017 because the company did not conduct studies on the mine's impact on indigenous communities or comply with the requirement for a free, prior and informed consultation process. Belo Sun submitted the studies of the indigenous component to the National Indian Foundation (FUNAI) in early 2020 and is awaiting an assessment and response from the entity. Ángel's assessment was presented to FUNAI and the Secretary of State for the Environment (SEMAS) of Pará, the entities responsible for granting licenses for the project. The expert opinion joins two others presented as part of a joint effort by independent researchers whose work explicitly demonstrates the unfeasibility of the Belo Sun project as it is currently conceived. The previous opinions focused on the negative impacts of the project on the ichthyofauna, and on the fragility of the environmental impact studies submitted by Belo Sun from a geological point of view. In addition to the independent researchers, several organizations have denounced the social and environmental unfeasibility of the project, including the Xingu+ Network, the Xingu Alive Forever Movement, Amazon Watch, the Socio-Environmental Institute (ISA), International Rivers, Above Ground and AIDA.

Expert report: proposed gold mine in Brazilian Amazon presents unacceptable risk

Altamira, Brazil. An expert study released today reveals serious deficiencies in the environmental impact assessment submitted to Brazilian authorities by Canadian mining company Belo Sun. The analysis exposes an unacceptable degree of risk that the tailings dam at the proposed Volta Grande gold mine will fail, contaminating the Xingu River and harming nearby indigenous and other communities. The report’s author, Dr. Steven Emerman, explains that despite the presence of geological faults at the mine site, the company has not produced any seismicity studies. Nor has the dam been designed with seismic safety in mind, in violation of Brazilian tailings dam regulations.  Dr. Emerman also raises concern about the company’s use of its tailings reservoir to capture water. Industry best practice is to prevent the flow of surface runoff into tailings ponds in order to minimize the risk of dam failure. Moreover, the report reveals that Belo Sun has provided contradictory information regarding its tailings storage plan to investors and Brazilian regulatory authorities. Dr. Emerman recommends that the project’s licence be revoked. Brazilian courts suspended Belo Sun’s installation licence in 2017 because the company failed to study the project’s impact on indigenous and other traditional communities, or to consult these populations. Belo Sun has been criticized for publishing misleading statements to bolster sagging interest in the project among potential investors, amidst growing evidence of social, environmental, financial and reputational risks. Last week local movements Rede Xingu+ and Xingo Vivo para Sempre submitted Dr. Emerman’s report to government agencies responsible for project licensing. These organizations demand that additional studies be undertaken, which they argue are “indispensable to assess the social and environmental viability of Belo Sun’s mining project considering the grave risk to indigenous and other river-dwelling communities located next to the project and its tailings dam.”      FAILURES, INSECURITY AND CONFLICTING INFORMATION From conflicting information to the absence of seismic safety criteria, Dr. Emerman's opinion highlights eight main points that support the recommendation to reject the Volta Grande project: The tailings dam was not designed under any seismic safety criteria, violating Brazilian regulations in this regard. Any tailings dam should be designed to withstand events such as floods and earthquakes. Contrary to the Brazilian standard, the company did not include in its studies an analysis of local seismicity nor did it simulate the response of the structure to a hypothetical seismic acceleration.   Although geological faults have been mapped at the tailings dam site, no local seismicity studies have been done, which also violates Brazilian tailings dam regulations. Seismic activity is responsible for causing the dissolution of saturated debris into water, one of the most common causes of tailings dam failures.  In Brazil, in 2019 alone, there were three dam failures, including the rupture of the Vale dam in Brumadinho (Minas Gerais), which caused at least 250 deaths. Cases like these demonstrate the need for and importance of local seismicity studies and are indispensable for the proper assessment of the risk of failure of a tailings dam.   No risk analysis has been made of the geological faults mapped in the vicinity of the project site. Three of these faults, which are structures present in rocks and which can promote seismic movements, intersect at the exact site of the proposed tailings dam.   The official simulation of the rupture assumes, without justification, that the flow of the waste would be interrupted when it reaches the Xingu River, ignoring the capacity of the toxic elements to travel tens of kilometers along the Volta Grande. The conclusions of the EIA also support the hypothesis that the tailings flow would take 97 minutes to reach the Xingu, but without mentioning the details of the calculation used. According to the modelling presented in the opinion, considering the volume of tailings stored on the order of 35 million cubic metres and assuming a spill of approximately 25%, under a conservative scenario the flood would cover an initial distance of up to 41 kilometres along the river. At a speed of 20 km/h, the flooding of Belo Sun's dam would reach the Xingu in only seven minutes, covering the distance of 41 km in only two hours, reaching the Volta Grande Indigenous Land. After the rupture of the Vale Dam in Brumadinho, the tailings flow reached 120 km/hr, 100 km/hr more than the more conservative scenario proposed in the report. In the worst case, with the release of 100% of the stored tailings, the initial flow would cover 98 kilometers along the Xingu River and could reach the Amazon River and the Atlantic Ocean.   There is a high risk of toxic water spillage into the Xingu. The project provides for the recycling of cyanide leachate, a substance used to separate gold, which can result in waste water that is highly enriched with toxic elements such as arsenic and mercury. The result, whose analysis is absent from official documents, could be the spillage of a waste-water mixture that is highly toxic to aquatic organisms into the Xingu River in the event of a dam failure or spill.   There is no plan in the EIA to close the mine or tailings dam, a key issue for the social and environmental viability of the mining project. The document contains a promise by the business group to find out, after the event, how to permanently stabilize the tailings dam.   The waste storage system adopted at the time is not viable and runs counter to good mining practice. Part of the solution to reduce the probability of tailings dam failure is to reduce the water content in the tailings tank. But the Belo Sun project envisages that all the waste will be saturated and under seven metres of free water, above the surface of the solid waste.   Aware of the issue raised in the previous point, the company seems to have decided that the current plan to flood the waste is not feasible. The Chief Executive Officer of Belo Sun Mining stated o MiningWatch Canada that he would abandon the current plan for a filtered tailings storage facility, which should have a significantly lower water content. However, the company provided conflicting information to Brazilian organizations and regulatory authorities: in a presentation to FUNAI in October 2019, the company described the same wet waste storage plan as the EIA. "The provision of contradictory information to different audiences by Belo Sun Mining and its Brazilian subsidiary is very serious in terms of the reliability of the information provided in the administrative processes," the opinion reiterates.

Continued extractive activities put indigenous and rural communities at increased risk from the pandemic

In most Latin American nations, governments have implemented health and social isolation measures to contain the spread of the COVID-19 pandemic.  Within the framework of these restrictions, exceptions have been established for activities considered essential, including emergency care, the provision of health services, and the marketing and supply of essential goods.   However, the governments of Bolivia, Ecuador and Peru have also exempted mining and oil activities from the restrictions, stating they are in the national interest.  The exceptional treatment accorded to extractive activities in some countries of the region has significantly increased the vulnerability of indigenous peoples, and amplified the risks and threats they face, since these operations are carried out in their territories. In addition, the entry and exit of workers without proper health measures diminishes the effectiveness of the protective measures adopted by these peoples, such as epidemiological fences or social isolation. Thus, there is an increase in the spread of the virus and in the number of infected persons. In addition, in practice, these rural populations have little or no access to the health and sanitation services needed to deal with a health crisis such as that generated by COVID-19.  At the regional level, the Coordinating Body of Indigenous Organizations of the Amazon Basin (COICA) has demanded that States guarantee access to health and food for the indigenous peoples and nationalities of the Pan-Amazon, as well as to intensify surveillance and protection of the territories "invaded by oil, mining, logging and other people." The particular situation of each country is as follows: BOLIVIA In late March, the government issued a Supreme Decree establishing that companies that "provide services for the supply of gasoline, gas, diesel and other fuels" are authorized to continue their operations "without interruption.” The decision has generated concern among indigenous organizations. "In Tarija and part of Santa Cruz, as well as in El Chaco, the oil companies continue to work with total normality. There are changes in personnel that arrive in vehicles continuously. Our fear is that they will bring the virus to the indigenous communities," indigenous leader Alex Villca, member of the Coordinating Committee for the Defense of Indigenous, Native, Peasant and Protected Areas Territories (Contiocap), told Mongabay. ECUADOR The organization of the Waorani Nationality of Ecuador (NAWE) alerted the national government to the detection of two positive cases of coronavirus among the workers of Block 16, which would be operated by the company Repsol YPF. The Waorani called on the government to adopt special protocols for "the protection of territories and indigenous populations," adopting measures to control and restrict the activities of oil company personnel who "are operating legally in indigenous territories and to prevent the propagation of the pandemic." Repsol Ecuador S.A. informed in a press release that the two positive cases correspond to workers of a contracting company who, after being previously tested, did not enter the company's operations. PERU In March, the government issued a Supreme Decree to combat the health crisis resulting from the pandemic. The decree provides for restrictions on the right to freedom of movement, exempting from this measure certain welfare and economic activities considered essential. Mining was not one of them. However, the Ministry of Energy and Mines included mining among the essential activities that must still be carried out in quarantine to ensure minimum operations, saying it would do so without affecting the integrity of workers and communities. This decision came after the National Society of Mining, Oil and Energy and the National Confederation of Private Business Institutions separately stated that the mining industry could not be stopped. The National Organization of Andean and Amazonian Indigenous Women of Peru criticized this decision. The presence of mining and oil operations in indigenous territories "puts the lives and health" of those peoples at risk, they said.   In the context of the pandemic, states must implement comprehensive and concerted health strategies to respect, guarantee and protect indigenous and peasant communities near mining or oil exploitation projects and other activities that put them at risk.  

Webinar "A Just Transition: Why should industrialized countries reduce their consumption of raw materials? The case of Germany"

The global expansion of renewable energies, electric mobility and digitalization will massively increase the demand for raw materials. This implies the risk of damage to human rights and the environment, as well as an intensification of geopolitical tensions over these resources. In this context, a globally inequitable distribution of raw material consumption would jeopardize the sustainable and fair development of the countries of the Global South.In this webinar, we presented the proposals of an NGO network in Germany to achieve a reduction in the consumption of raw materials and to include the perspectives of producer countries, supporting their call for a "change in raw materials" (Rohstoffwende). PanelistRebecca Heinz: Policy Advisor – Resource Policy at Germanwatch. Recording Presentations1.

Preserving the legacy of the Sierra Nevada de Santa Marta, Heart of the World

Learning from Mendoza, Argentina: “Water is not negotiable

Near the end of 2019, the citizens of Mendoza, Argentina united in one of the province’s most important social manifestations. Their objective was clear: to defend their water. People of all ages—members of NGOs, environmental assemblies, anti-mining movements, scientists and academics—took to the streets to demand that the local government reverse the modification of Law 7722, known as "guardian of the water" or "the people’s law." The law is fundamental for the protection of water in Mendoza because it prohibits the use of cyanide, mercury, sulfuric acid and other toxic chemicals in mining activities—all of which seriously contaminate rivers, lakes and other natural water sources. Enacted on June 21, 2007, this law resulted from a long struggle by civil society. A step back in environmental protection The government intended to modify Law 7722 with another regulation, Law 9209, which allowed for "the use of chemical substances [including cyanide], mixtures or dissolutions of them, to ensure the sustainability of the [mining] project.” The justification for eliminating the prohibition on the use of cyanide and other toxic elements was "to guarantee the sustainability of the use of natural resources, with special emphasis on the protection of water resources and to ensure compliance with mining activities.” The use of cyanide in legal mining is becoming less frequent due to the risks involved in its manufacture, transport and use. Cyanide compounds are highly toxic in their gaseous form or when dissolved in water. Considering that the limit of cyanide in drinking water for safe human consumption is four drops per liter, the concentrations used in mining present high risks. In addition, there is abundant evidence of cyanide spills and losses from mining facilities during transport, and multiple cases of mass fatalities of wildlife near mining facilities, particularly migratory birds. The legislative amendment sought to make the procedures for environmental control and monitoring more flexible, by establishing that it was no longer obligatory for the Environmental Impact Statement of a mining project to be ratified by law. This undermined the effectiveness of Law 7722. These changes, promoted by the government of Mendoza, violated environmental protection principles contained in Argentina’s Constitution, among them sustainability and other national regulations that the provinces are obliged to comply with and enrich. For example, article 41 of the Constitution states that "all inhabitants have the right to a healthy, balanced environment, suitable for human development and for productive activities to satisfy present needs without compromising those of future generations; and they have the duty to preserve it." The citizen's response The social response to this modification—which intended to give free rein to the use of substances with a high environmental impact—surpassed all precedents. By successfully reversing an initiative already approved by Mendoza's legislators, it became an example for the entire region. The largest demonstrations in Mendoza's history began on December 22. Under the slogans "water is not negotiable" and "water is worth more than gold," the people of Mendoza organized to express their disapproval of the new law. The following day, 50,000 people gathered in front of the Provincial Government House after a journey of more than 100 kilometers, which began in the town of San Carlos, in the Uco Valley. They demanded: Law 7722 is not to be touched. Despite this widespread popular rejection, the Governor of Mendoza enacted the reform. Then, thousands of self-convoked neighbors gathered at kilometer zero—between San Martín and Garibaldi Streets—in the provincial capital to demand the law’s repeal. On December 26, faced with constant and growing social pressure, the Governor announced that he would not enact the new law. That palliative measure was deemed unconvincing and mobilizations intensified. The Governor then decided to reverse the amendment to Law 7722. On Friday the 27th, he announced the reform’s repeal, which finally happened on Monday the 30th. The case of Mendoza teaches a valuable lesson to all Latin American countries: When citizens are aware of the importance of nature and the scale of the dangers it faces, they will not yield. Socio-environmental conflicts are not only a response to those who have control over natural resources, but also to their effects on a complex social network. For humans and also for other beings, nature is a formative part of our identity, culture and customs. We are part of it and it is part of us. It is a living and interconnected network. That is why we must be its main defenders. The prompt and necessary updating of the concept of "sustainable development" is one of the challenges of Environmental Law in the 21st century. We mustn’t promote development that attacks nature and ignores human rights.   Learn more about the use of cyanide in mining (in Spanish).
