Climate Change

Nature first: it’s time to build environmental consciousness

Speaking in front of more than 500 people was a unique and beautiful experience, above all for the reason I came together with such an amazing group of people. We were seven diverse individuals with two powerful things in common: our love for the natural environment and our work to preserve it. We were in Santiago, Chile as part of the conference, “Nature first: a new deal with the environment.” The great interest the audience had in the event filled me with such joy, as did the opportunity to speak beside my colleagues from The Naturalists, a series of interviews in which professionals from distinct environmental professions were invited to speak about what being a naturalist implies in the modern world.  The video series and this event was put on by Ladera Sur, an online platform and community built around nature, the environment, the outdoors, travel, and much more. It was Ladera Sur that introduced us as 20thCentury Naturalists, a great honor and an even greater obligation. But what does “nature first,” a title with such urgency, really mean? It means that, for too long, nature has been subsidizing our technological advancements and even our quality of life. We live in a world in which those who have the means can do practically anything. Perhaps some of us have stopped to think about tomorrow, and how it may be difficult for our children or grandchildren to enjoy even the simplest things in life. But the time has come to reorganize our priorities. We have neither the time, nor the credit, to continue borrowing from nature. Before proceeding with any potentially harmful project or activity, we first must demonstrate that the activity would not hurt the health of the planet. Only after assuring that is it worth asking whether a project is also good business, or if it will make our lives easier or more comfortable.  This is not the position of an eco-terrorist, nor is it counter to economic development. It’s simply looking ahead at the reality of a living on a sick planet—a planet on whose health we depend. The good news is that the changes we need to make to resolve the environmental crisis are not only achievable; they are what people living on this planet actually want. A world with low emissions is a cleaner and more just world; a world driven by renewables means less pollution and more equitable access to energy; a world with more protected natural areas is a greener, healthier, more verdant world; it is rich in biodiversity and has a greater capacity to provide clean air and water. See the complete video of the conference below.  

Clean air and climate justice: the best gifts for our children

Today Mexico celebrates Children’s Day. The best gift we can give to millions of boy and girls is clean air and climate justice. It’s the only thing I want to give to my children that, sadly, I can’t, at least not this year. Mexico City, where we live, has had bad air quality 112 of the 120 days of 2019, thus far.  Those of us who live in this city have suffered from contamination, particularly over the last month; three “environmental contingencies” (air pollution alerts) for ozone were declared for a total of seven days.  In recent years, contingencies have occurred during peak ozone season—February 15 to June 15—a period in which tropospheric ozone (present in the air we breathe) exceed the maximum levels allowed by Official Mexican Law. This gas, present throughout the year, rises when the burning of fossil fuels by vehicles and industries is compounded by changing weather conditions: less rain and winds, and more solar radiation. This prevents the air pollution that we produce from dispersing into nearby areas. Increased ozone causes serious damages to the environment and public health, particularly to children. According to the Pan American Health Organization, ozone in the air can affect lung function, making breathing difficult. Thus, the group most vulnerable to contamination also includes people with respiratory diseases, older adults and athletes. Authorities recommend that the people, particularly vulnerable groups, abstain from outdoor activities during the contingencies, particularly between 1:00 and 7:00 p.m. Other measures include increasing vehicle restrictions and reducing the consumption of liquefied petroleum gas. Despite its harsh realities, ozone season is not a new or surprising phenomenon, nor is it normal. It shouldn’t be normal for parents to resign ourselves to its presence, to birthday parties indoors and not letting our children go to the park with their friends.  I understand the impossibility of controlling the rain, sun and wind; but ozone is another story. There are clear measures that could and should have been implemented years ago to prevent the ozone season from being unavoidable in Mexico City. Already fully identified, they include: improving the quality of gasoline, vehicular technology and fixed sources; ensuring safe and adequate public transportation and bicycle infrastructure; and effectively controlling fleets of private and public transport.  Until now, these actions have been incomplete, inefficient and unable to solve the underlying problem. But the improvement of air quality during gasoline shortages has demonstrated that such solutions are possible. What’s more, actions aimed at reducing air pollution could have a double benefit. Tropospheric ozone is a greenhouse gas that aggravates climate change. It is a short-lived climate pollutant that stays in the atmosphere for only a few weeks, meaning that actions to control it have an almost immediate effect on public health, ecosystems and the climate. Therefore, in addition to improving the health of millions of people living in cities, Mexico has the opportunity to fulfill its international obligations on climate change. Diminishing ozone season requires the urgent and structural change of public policies, laws and their application. New standards must include a human rights perspective that prioritizes public interest and the health of children, and others, above vehicular mobility. While the development and implementation of these measures may not be easy, it’s essential we take the first steps toward the results we want to achieve.  Government efforts require the support of our entire society. Companies must contribute to the implementation of solutions, acting with due diligence. Academics, civil society organizations, trade unions and other sectors must contribute with our knowledge and participation to ensure that the plans and programs are ambitious and effective, and that they promote a just transition. Every resident of the city has a duty to contribute. A few weeks ago, Professor David Boyd, the United Nations Special Rapporteur for Human Rights and the Environment, published a report reiterating the obligation of States to guarantee the right to clean air, and the duty of companies to contribute. The report has recommendations related to tropospheric ozone that could be very useful for Mexican authorities. The enjoyment of clean air is a right that has yet to be met. Today almost two million children (from 0 to 14 years old) live in Mexico City, including mine. They and a large part of the more than 35 million children across the country could enjoy clean air; most live in cities and towns with air quality problems. According to organized trade, the celebration of Children's Day in Mexico involves an expenditure of 17 billion pesos ($900 million dollars) in gifts, an amount that could be used for authorities, companies and individuals to implement actions to ensure that the children of the country have something much more valuable: the ability to breathe air that does not endanger their health. This would be aligned with the goal of those who instituted the celebration of Children's Day in Mexico in 1924, and with the intention of the United Nations to establish one day a year to honor the importance of children's rights. Air pollution is, unfortunately, a regional and a global problem. Peru and Colombia also celebrate their children this month. Since their cities are among the most polluted in Latin America, what is reflected here can also be applied to those countries, and the continent as a whole. My gift for my children this year will be to continue working for better air quality in Mexico City, and to collaboratively build a future—hopefully a not-so-distant one—in which climate justice is a reality.  

How fracking's methane leaks aggravate climate change

I’ve seen them more times than I can remember, but the shock never fades: ten-foot-high flames burning off gas at the BP processing plant in Whiting, Indiana. The facility is close to where I grew up, so we’ve had a lot of time to marvel at the flare stacks. My sister thought they were volcanoes when she was little and, in my family, the name has stuck. Converting waste methane to carbon dioxide (CO2) through flaring is common practice in oil and gas production. This makes “volcanoes” a familiar feature of drilling and hydraulic fracturing, or fracking, fields. The sight of stacks spewing CO2 directly into the air is both visually striking and enraging: a visual metaphor for a world run on extractive, dirty energy. And yet, when it comes to fracking, the volcanoes and their carbon emissions aren’t even the biggest problem. That which is most dangerous is often hardest to see—invisible, in this case. Fracking’s worst air pollution actually occurs through methane leaks. Methane is a greenhouse gas whose global warming potential is 86 times greater than carbon dioxide over a 20-year period, according to the Intergovernmental Panel on Climate Change. It leaks stealthily at every point in the gas supply chain into our atmosphere, undetectable without advanced equipment and frequent tests. According to NASA, the oil and gas industry is responsible for the global rise in methane emissions, beating even landfills and dairy production. Many of these emissions come from leaking pipes attached to fracked gas wells. While many of fracking’s damages—the contamination of water tables, an increase in man-made earthquakes—are well documented, fracking’s air pollution is a more difficult battle to fight. There are no convenient visuals of tap water set on fire or flattened homes. But the fact that we can’t see methane leaking into the air doesn’t make its impact any less intense: diffuse toxic particles grip the throat like so many invisible hands; methane causes nosebleeds and asthma; gas leaks squeeze the brain into dizzying headaches and seizures; toxic additives cause babies to be born prematurely with low birth weight and life-threatening defects. Leaking methane is also of particular concern when it comes to climate change. When just less than 2 percent of a pipeline’s total carried methane leaks into the air, the gas loses its supposed “cleaner” climate advantage over even coal. Recent studies show that U.S. fracking fields leak at tremendously uneven rates, some up to a whopping 12 percent. In other words, only a small number of wells are responsible for an extreme amount of contamination. But this also means that we already have part of the solution: fixing leaks at these super-polluting fields would be a huge boon for climate regulation.   Leak detention and repair requires frequent and careful oversight, but it is also cost-effective, and often actually pays for itself. Gas companies can patrol their own distribution lines, looking for and repairing leaks. Pneumatic pipeline controllers can be replaced with better, low-bleed controllers. This extra care, however, is exactly what fracking’s proponents fight against: the gas industry in the United States has long denied and diminished the severity of leaking pipelines. Like the greenhouse gas pollution that causes it, climate change is a slow-paced disaster. It is a long, diffuse emergency that, in a sound-byte world, isn’t dramatic enough for short-term elections and news cycles, and usually isn’t brought up until it’s too late. Alternatives to fracking But times are changing. And the solution to a warming world isn’t just about fixing leaks. We can’t just mitigate a life-threatening system; we have to end it. Instead of perpetuating our dependence on gas, we must invest in a just transition and move into economically sustainable forms of energy, like solar and wind. Gas delivery systems and their maintenance are as expensive as they are toxic, and will soon become obsolete. We must fight for better regulation of our present system, while building up alternatives for a better tomorrow. This is particularly important in parts of the world that are only now starting to embrace fracking. While somewhat ubiquitous in the global North, fracking has only just begun in Latin America, where roughly 5,000 wells have popped up in the past few years. Frontline communities and human rights defenders from across the Americas have fought hard to win bans or restrictions on fracking. They urge that their nations not fall for fracking’s trap—harms would be amplified by lax regulation and further aggravate climate change. In October they testified before the Inter-American Commission on Human Rights on the harm fracking has caused to communities across Latin America. Liliana Ávila, a senior attorney at AIDA, explained that fracking-induced pollution impacts basic human rights, and that environmental defenders often face extreme violence when protecting their territories from the gas industry. Part of the battle for a global and just transition towards a sustainable, equitable energy economy is being able to recognize those harms that are harder to see—including those that are invisible at first. It’s the quiet harms that unfold over long time spans that are catching up to us now.  

Putting my heart in the conservation of wetlands

Coral reefs are my favorite wetlands. They’re full of so many colors and shapes, and simply teeming with life. When I’m underwater, my heart is full of peace and excitement, as I see myself surrounded by so many forms of life, so many species living together. As a marine biologist, I’ve had the opportunity to scuba dive in a variety of countries and see many of these beautiful ecosystems up close. Of all my dives, the ones I enjoyed most were those I did—for work and for pleasure—in the Bay Islands of Honduras. As a recent college graduate and volunteer with the Atlantic and Gulf Rapid Reef Assessment Program, I was in charge of monitoring the countless organisms that live in or on the reefs—seaweed, sea urchins, lobsters, queen snails, and so many others. Without a doubt, my time diving in the Cayos Cochinos sparked my personal and professional journey. Since then, I’ve set out to protect these magical ecosystems, vital to all life this planet. My current role, as scientific advisor to AIDA, uses science to strengthen the legal arguments employed to protect these and other at-risk natural environments in Latin America. Wetlands, vital and at-risk In addition to coral reefs, wetlands—characterized by the presence of water—include lakes and rivers, underground aquifers, swamps and marshes, grasslands, peat bogs, estuaries and deltas, mangroves, and sea grasses. Wetlands act as the “kidneys” of the planet because they recycle water and waste, retain sediment and nutrients, reduce erosion, and absorb carbon dioxide from the atmosphere, in turn mitigating climate change. However, it’s estimated that since 1700 we’ve lost nearly 87 percent of our wetlands at a speed three times greater than the loss of our natural forests. This has caused a drastic reduction in biodiversity, affecting 81 percent of continental species and 36 percent of marine and coastal species. Among the greatest threats to our wetlands are contamination by garbage, wastewater and industrial pollution; changes in land use; agricultural runoff, erosion and climate change. What’s more, global warming is increasing the temperature of the oceans, raising sea levels, and melting the poles. According to the Intergovernmental Panel on Climate Change, an increase of 1.5°C in global temperature could kill almost 90 percent of the world’s coral reefs—an irreversible and heartbreaking loss. Taking action to save wetlands Given this frightening global scenario, urgent action is required to protect our planet’s wetlands. In fact, there are many ways we can begin to do so immediately, such as: Creating restoration campaigns for vital ecosystems like mangroves and coral reefs. Declaring natural protected areas, to conserve wetlands and the species that depend on them. Developing policies that allow for the rational use of wetlands, where conservation is prioritized. Prohibiting the destruction of these ecosystems in any type of project, be it tourism, development or infrastructure. Establishing water treatment plans to prevent drainage and runoff from contaminating wetlands. Every year, on February 2, we celebrate World Wetlands Day, commemorating the signing of the Ramsar Convention, the only intergovernmental treaty for the conservation and rational use of our planet’s wetlands. This year’s celebration is focused on wetlands and climate change, inviting us all to reflect on the value of our wetlands, the critical services they provide, and urgency with which we must protect them. We are not powerless in the face of climate change. Saving our wetlands may just be the first step toward saving our planet, and ourselves.  

10 environmental successes from Latin America in 2018

  This year was characterized by triumphs such as the creation of legal protections and the establishment of policies favorable to the environment and human rights in the region. Rarely in a single year do we see so many precedent-setting institutional advances. What follows are 10 stories we applaud from 2018: 1. For the first time, the Inter-American Court recognized a healthy environment as “fundamental” In its first time speaking on the subject, the Court concluded that a healthy environment is an autonomous right, “fundamental to the existence of humanity.” The relationship between the environment and human rights may sound obvious, but until February of this year, when the Court’s opinion was made public, there were no precedents of this magnitude recognizing the link. The opinion responds to a query made by Colombia. In it, the Court also recognizes that climate change impacts the enjoyment of human rights, especially among the most vulnerable populations. The OC-23, as it is known, established a historic precedent for the protection of human rights in the Americas and will be an important tool for environmental justice in the region. Learn more 2. Nations adopt the first regional treaty on environmental issues Over the course of the year, 16 nations have signed the Escazú Agreement. Not only is it the first treaty on environmental issues in Latin America and the Caribbean, it is also the first in the world to include provisions on human rights defenders in environmental matters. Its main objective is to guarantee the rights of access to environmental information, public participation in environmental decision-making processes, and justice in environmental matters. Learn more 3. Parrotfish receive special protection in Mexico Schools of colorful parrotfish feed on the macro algae that compete with coral for light and oxygen, helping to improve coral health. But overfishing and other factors have caused parrotfish populations to decline, placing corals at greater risk. In an effort to protect this key ally of the reefs, 10 species of parrotfish are in the process of being included in the Mexican government’s list of protected fauna. Learn more 4. Indigenous peoples recognized in climate finance Following years of work by indigenous peoples around the world, the Green Climate Fund approved an Indigenous Peoples Policy with the objective of protecting, recognizing, respecting and promoting their rights within the financing of climate projects. The decision was received with hope in a world that requires immediate actions to mitigate and adapt to climate change. This sort of policy helps to prevent climate finance from violating the rights of the most affected populations. Learn more 5. A regional plan to protect jaguars Conservation organizations teamed with 14 nations to launch Plan Jaguar 2030 with the intention of protecting corridors, or natural routes, linking populations of the largest carnivore in Latin America without natural predators. Jaguar populations extend through 18 countries, but are rapidly diminishing due to poaching, habitat fragmentation, and conflict with human activities. In El Salvador and Uruguay, they have been declared extinct. The plan provides hope for jaguar protection across borders. Learn more 6. Colombia says no to fracking pilot tests The Colombian Environmental Licensing Authority (ANLA, for its initials in Spanish) denied permission for ConocoPhillips to carry out the first hydraulic fracturing pilot tests for the extraction of hydrocarbons in San Martin and Aguachica, in the department of Cesar.  ANLA argued that the information presented by the corporation was “insufficient” to understand the management and availability of water, and also questioned its environmental evaluation and contingency plan. For now, the initiative is archived. Continuing to bet on fossil fuels moves nations further away their climate goals; it is important to commit to a clean energy transition. Learn more 7. A region fight against fracking reaches the Inter-American Commission Organizations and communities from across the region joined forces to bring before the Inter-American Commission on Human Rights cases of human rights violations and threats to the environment caused by fracking. After various local struggles, this was the first time that the damages documented in nations across the Americas were presented before a regional organization. The Commissioners responded with great interest to the testimonies presented. Regarding this issue, the new government of Mexico said there will be no more fracking in the nation. Learn more 8. A treaty to protect two-thirds of the ocean Following a decade of discussions, negotiations began at the United Nations for a legally binding treaty to protect biodiversity on the high seas, those marine areas outside of national jurisdictions. Negotiations will take place until 2020. Although the high seas represent 64 percent of the total surface area of the ocean, and the ocean absorbs 90 percent of the heat caused by global warming, no overarching treaty exists to protect this ecosystem, only fragmented regulations. Learn more 9. Chile closes the Pascua Lama mine In October Chilean authorities confirmed the definitive closure of Pascua Lama, a gold mining project on the border of Chile and Argentina. Barrick Gold, the company in charge of the project, was fined for 33 violations of Chilean environment regulations. Pascua Lama caused great damage to native plants and animals. Indigenous peoples of the region—who had documented the contamination of a river and impacts on glaciers, an important water source—celebrated the decision. Activists are now seeking to stop the project on the Argentina side of the border. Learn more  10. Argentina’s creation of National Parks breaks record Just before the end of the year, Argentina announced the creation of two marine protected areas: Yanganes, south of Tierra del Fuego, and Namuncurá-Burdwood Bank II, in the south Atlantic. Both are important sites for the breeding and spawning of fish with high commercial value. With this pair, the country added six natural areas declared as national parks in 2018 alone, a truly historic effort. The other parks include: Traslasierra, Aconquija, Ciervo de los Pantanos and Iguerá. Argentina has proposed the protection of 10 percent of its seas by 2020. Learn more  

Why we’re working for climate justice in Latin America

“The world has many problems, but to me none seem as ubiquitous or as dangerous as climate change,” says AIDA attorney Florencia Ortúzar. “It really is the great challenge of our generation.” At AIDA we understand the magnitude of the problem. That’s why we incorporate climate justice as a key concept in all our lines of work. It’s why we advocate for sustainable development that respects the environment and the rights of vulnerable communities and, at the same time, why we work to stop climate-aggravating activities. “What motivates me to fight climate change is my awareness of the huge problem we’re facing, and my steadfast determination—I know we can’t give up,” Florencia says. She shares that motivation with AIDA’s entire team of attorneys, scientists, communicators, fundraisers and administrators. When she was a child, Florencia received a very special gift from her father: a badge that said “world saver.” That very day, on a beach in her native Chile, Florencia hooked the badge to her clothes and began picking up trash, cleaning the beach. That small gift jumpstarted her life’s mission. Florencia went on to study law, with the goal of working for the protection of forests, rivers, animals, and all the elements of the natural world. “Luck was with me when I found AIDA, the organization that has trained me and has enabled me to make my contribution to a better world,” she says.  Florencia is part of AIDA’s Climate Change program. Our objective is to help Latin America—one of the regions most vulnerable to the climate crisis—be a leader in the type of changes required on a global level to avoid catastrophe. In partnership with allied organizations and hand-in-hand with communities, we work to stop the blind advance of fracking and large dams, mega-projects which imply significant emissions of methane, a greenhouse gas 34 times more powerful than carbon dioxide. We also work to raise awareness and educate public policy makers on the importance of controlling short-lived climate pollutants. We seek to protect terrestrial and marine ecosystems that capture carbon emissions—such as coral reefs, mangroves, wetlands and páramos—which, in turn, helps to mitigate climate change. We monitor international climate negotiations, advocate for Latin American nations to have the necessary economic resources to deal with climate change, and work to ensure that climate finance respects human rights. “Although many of the effects of climate change are inevitable, and may already be occurring, the efforts we make to stop the problem and to adapt to it will help future generations, who had nothing to do with causing the problem,” Florencia explains. She shares her message wherever she goes, encouraging others to join the fight. “I refuse to be part of the last generation to enjoy the natural wonders of our planet.”  

UN Committee recommends Argentina “reconsider” the use of fracking

The Committee on Economic, Social and Cultural Rights of the United Nations expressed its concern about Argentina’s intention to exploit unconventional oil and gas reserves in Vaca Muerta, one of the world’s largest shale deposits. It recommended the goverment reconsider those plans to ensure compliance with the nation’s international commitments on climate change. ​ Geneva, Switzerland. The Committee of Economic, Social and Cultural Rights of the United Nations recommended that Argentina reconsider its plans for the large-scale exploitation of shale gas and oil in Vaca Muerta, one of the world’s largest deposits of unconventional hydrocarbons. The Committee expressed its concern after reviewing the nation’s fourth report to the Universal Periodic Review on human rights, encouraging the government to reconsider the use of fracking in order to ensure compliance with its international obligations on climate change. "The Committee is concerned that this hydraulic fracturing project contradicts the State’s commitments to the Paris Agreement, and would have a negative impact on global warming and the enjoyment of economic and social rights by the global population and future generations," read the concluding observations on Argentina's report, approved by the Committee at its 64th session, which took place from September 24 to October 12, 2018. The Committee urged the State "to promote alternative and renewable energies, reduce greenhouse gas emissions and establish national targets with benchmarks defined over time." The Committee also expressed concern about the lack of adequate evaluation of fracking’s negative impacts on the environment and human health, and about the absence of prior consultation with affected local populations. In that sense, the Committee entrusted the Argentine State to: "... adopt a regulatory framework for fracking that includes assessments of its impact in all provinces, preceded by consultations with affected communities, and with appropriate documentation of its effects on air and water pollution, radioactive emissions, risks to health and safety at work, its effects on public health, noise pollution, light and stress, potential seismic activity, threats to agriculture, soil quality, and the climate system." The UN Universal Periodic Review is a process that offers each State the opportunity to declare what measures it has adopted to improve the human rights situation in the country and to comply with its obligations in this area. Its objective is to improve that situation and address human rights violations wherever they occur.

The IPCC climate report: science has spoken and we must act now

The international scientific community has spoken: the only thing that can save us from a climate catastrophe is a radical and immediate change. The next 11 years are the most important in the history of the planet, in terms of climate change. Our response to their message will determine our future. In its most recent analysis, the Intergovernmental Panel on Climate Change (IPCC) of the United Nations establishes the impacts that could occur if the planet’s average temperature increases by more than 2°C, and compares those with what would happen if we stop warming, or at least keep it below 1.5°C. The 2016 Paris Agreement, an international accord to curb climate change, aims to keep warming well below 2°C with respect to pre-industrial levels, and to continue global efforts to limit it to 1.5°C. The impacts of global warming The IPCC experts’ conclusions are piercing. Those extra 0.5°C would be lethal for millions of people and their ways of life. If the Earth warms 2°C or more, we would experience: more frequent and intense heat waves, droughts and floods; sea level rise of an extra 10 centimeters, implying coastal flooding and filtration of salt water into agricultural areas and freshwater sources—a matter of life and death for roughly 10 million people; double the risk of habitat loss for plants and vertebrates, and triple the risk for insects, considering more than 100 thousand species which were studied; the disappearance of more than 99% of coral reefs, while 10 to 30 percent of what remains could be saved if we were to stabilize the planet’s temperature below 1.5°C; an increase in the range of mosquitoes that transmit diseases such as malaria and dengue; and the devastation of crops and livestock, severely affecting global food security. So, how are we doing now? Not so well. The planet has already warmed 1°C since preindustrial times, and in 2017 the emissions responsible for warming increased again. The commitments nations made to comply with the Paris Agreement are insufficient. Settling on that level of ambition would take us to 3°C warming by 2030, a reality with unimaginable consequences. Changing our climate destiny Let’s talk about solutions. Ensuring that the planet’s warming doesn’t exceed 1.5°C is possible, but it will require unprecedented action. Emissions must lower by 45 percent between 2010 and 2030, and we must achieve carbon neutrality by 2050. That means not emitting more than what the world’s forests and natural carbon sinks can absorb. This will require that: the most polluting industries, particularly those producing fossil fuels, implement radical changes; renewable energy is the norm by 2050, accounting for between 70 and 85 percent of total energy production; coal-fired power plants disappear; transportation runs with clean, renewable electricity; and we expand, maintain, and care for forests and other natural carbon sinks, which are responsible for removing emissions from the atmosphere. The IPCC report also recognizes a monumental opportunity: the mitigation of short-lived climate pollutants (SLCPs)—including black carbon or soot, methane, hydrofluorocarbons and tropospheric ozone. More climatically intense than carbon dioxide, SLCPs are responsible for half of global warming. Because of their short duration in the atmosphere, they could play a key role in reducing warming in the short term. In addition, the reduction of SLCPs brings important benefits for human well-being, including the reduction of pollution that affects public health and better yield of crops. But few countries have included the reduction of short-lived climate pollutants in their national commitments on climate change. At AIDA we’re working so that Latin American nations advance in the control of these emissions. As the region with the greatest potential for renewable energies, Latin America has the opportunity to be an example for the rest of the planet. The threats facing the region are great and avoiding them is well worth the effort. Climate change threatens to shake us from our very roots—melting Andean glaciers, increasing droughts and floods, diminishing freshwater supplies, driving species to extinction, increasing wildfires, favoring the spread of invasive species, losing corals and marine biodiversity, affecting food security, and wreaking havoc on people’s health and livelihoods. The outlook is clear: maintaining global warming below 1.5°C is not an easy task, but science holds it’s possible. We have the scientific knowledge, and the technological and financial capacity to achieve this goal. The responsibility now lies with governments, decision-makers and the private sector—together they must drive unprecedented changes. We must remember that implementing these changes is not just possible, it’s desirable. A world with fewer emissions is a cleaner and a fairer world for us and for future generations. What’s not to like?  

Protecting herbivorous fish, to secure a future for corals

Say no to large dams: 3 reasons to opt for alternative energy sources

By Florencia Ortúzar and Monti Aguirre* Hydroelectric energy has been one of the largest drivers of development in many Latin American nations, and still represents a large portion of the region’s energy matrix. But is it really the best option? In response to a blog by the Inter-American Development Bank reflecting on the future of the hydroelectric sector in Latin America, we’d like to reflect on what it means to continue betting on large dams in Latin America. What follows are three reasons why we must say no to more large dams: 1. Better alternatives to hydroelectricity exist, and should be considered in project planning Before selecting an alternative energy source, governments and companies should develop a strategic plan that analyzes energy needs and the best way of achieving them. In this analysis, all options must be considered. It’s worrysome that this doesn’t already happen. For example, in the case of the Hidroituango dam—thought to be the largest in Colombia and associated with serious socio-environmental damages—the government decided to not conduct a prior evaluation of alternatives. Although the law did not require it at the time, the evaluation was recommended and is an international standard that large financial institutions should apply when investing in projects of this type. Today, other energy sources—like wind and solar—are proven to be economically competitive, can be constructed more quickly, and do not aggravate climate change. Innovations in smart grids, power storage and batteries also solve intermittency problems and make hydroelectric plants unnecessary. Geothermal, tidal, and wave energy are alternatives, the potential of which we have not even glimpsed. The promotion of large dams only delays adoption of the truly clean energy solutions that Latin America and the planet desperately need. According to the Bank’s own studies, Latin America has the largest quantity and most varied sources of renewable energy in the world. The region's renewable resources could provide almost seven times the installed capacity worldwide, excluding hydroelectric power. Therefore, although the region still holds great potential for untapped hydroelectric power, it’s necessary to conduct a comprehensive evaluation of the situation, taking into account the costs and benefits as compared to other energy options. Only then can governments decide whether it’s worth continuing to invest in hydropower, or whether it’s better to opt for other types of energy—thus avoiding the social, environmental and financial impacts that come with large dams. 2. Large dams cause socio-environmental damage and are not profitable It has been demonstrated repeatedly that the socio-environmental impacts of hydroelectric plants are greater than initially considered. In addition to forced displacement and the criminalization of those who oppose them, large dams flood land, reduce river flows, and change the ecosystems of downstream wetlands, destroying habitats and contributing to species extinction. All this impacts the lives of nearby communities, limiting their ability to adapt to climate change. In economic terms, a study by the University of Oxford concluded that “even before accounting for the negative impacts on human society and environment, the actual construction costs of large dams are too high to yield a positive return.” In it, researchers show that the budgets and timeframes of large dam projects are consistently underestimated. Brazil’s Belo Monte Dam, for example, ran two times over its original budget, making it the most expensive public works project in the Amazon region. The budget of Chile’s Alto Maipo Dam has doubled four times over since the project was approved in 2009. Recognizing that the costs far outweigh the benefits, some countries have opted for dismantling large dams. And private companies have scrapped hydroelectric projects altogether because they are neither economically viable nor profitable. The United States government  has adopted a policy to refuse any loan, donation, strategy or policy supporting the construction of large dams. 3. Large dams contribute to climate change Climate change must be considered when discussing the relevance of hydroelectricity. Reservoirs generate significant quantities of greenhouse gases, particularly methane, which is 30 times more effective at trapping heat than carbon dioxide. Likewise, the construction of dams endangers valuable carbon sinks like rivers and forests. For that reason, a proper analysis of carbon dioxide and methane emissions should be conducted before choosing a dam project—a process that usually doesn't occur. Another aspect to consider is the vulnerability of dams to climate variations. Extreme rainfall increases sedimentation, which can cause structural problems and reduce the dam's lifespan. Droughts, now increasingly frequent, can render dams inefficient. As more dams lose efficiency, Latin America—now highly dependent on hydroelectricity—will be more vulnerable to energy shortages. Even more serious is the threat posed by large dams in extreme weather events. In a dam gave way during bad weather, erasing entire villages. In Laos earlier this year, mass evacuations were ordered after heavy rains threatened a dam collapse. In Kerala, India, torrential rains, coupled with the mismanagement of several dams, have caused unprecedented flooding. In certain countries, the risk of dams overflowing or collapsing has already been recognized as a serious problem. Over time, more hydroelectric plants will begin to deteriorate and will require large investments to safeguard the communities living downstream. As civil society representatives working for a more just and sustainable Latin America, we urge financial institutions like the Inter-American Development Bank to support the change we as a region need. We call on them to stop investing in large dams, which have been demonstrated time and again to be dangerous to the environment and local communities, costly for countries, and unsuited for our rapidly changing climate. It’s time for a better energy plan. And it’s time to invest in non-conventional renewable energy based on thorough, independent and high-quality social and environmental impact assessments, the planning and implementation of which respect human rights. * Monti Aguirre is the Latin America Program Coordinator for International Rivers.
