Preserving the legacy of the Sierra Nevada de Santa Marta, Heart of the World
Rising abruptly from Colombia’s Caribbean coast, the Sierra Nevada de Santa Marta reaches 5,775 meters (18,946 ft.) at its highest points, the peaks of Bolívar and Colón. It is the highest coastal mountain system in the world, a place where indigenous knowledge and nature’s own wisdom converge.
The sheer changes in elevation create a wide variety of ecosystems within a small area, where the diversity of plant and animal life creates a unique exuberant region. The melting snows of the highest peaks form rivers and lakes, whose freshwater flows down steep slopes to the tropical sea at the base of the mountains.
The indigenous Arhuaco, Kogi, Wiwa, and Kankuamo people protect and care for this natural treasure with an authority they have inherited from their ancestors. According to their worldview the land is sacred and shared in divine communion between humans, animals, plants, rivers, mountains, and the spirts of their ancestors.
Despite this ancestral inheritance, development projects proposed for the region have failed to take the opinions of these indigenous groups into consideration. The Sierra Nevada de Santa Marta is currently threatened by 251 mineral concessions, hydroelectric projects, agriculture, urban sprawl, and infrastructure projects.
Many of these concessions were granted without the prior consultation of the indigenous communities, which represents a persistent and systematic violation of their rights.
Mining, which implies the contamination and erosion of watersheds, threatens the health of more than 30 rivers that flow out of the Sierra; these are the water sources of the departments of Magdalena, César, and La Guajira.
These threats have brought this natural paradise to the brink of no return. With it, would go the traditional lives of its indigenous inhabitants, who are dependent on the health of their land and the sacred sites it contains.
The Sierra hosts the archaeological site of la Ciudad Perdida, the Lost City, known as Teyuna, the cradle of Tayrona civilization. According to tradition, it is the source from which all nature was born—the living heart of the world.
The four guardian cultures of the Sierra are uninterested in allowing this natural and cultural legacy to disappear.

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?

Parrotfish are vital to the health of coral reefs, and the Mexican State has an obligation to protect them. In a letter to the government, AIDA outlined the international obligations Mexico has to preserve its coral reefs, requesting that ten species of parrotfish be included in the nation’s list of protected species—a proposal spearheaded by the Healthy Reefs Initiative. Mexico City. Using arguments based in international law and knowledge of environmental treaties, the Interamerican Association for Environmental Defense (AIDA) requested that the Mexican government include ten species of parrotfish in the national registry of protected species, under Official Mexican Law 059, which is currently being updated. AIDA made the request through a letter to the National Advisory Committee for the Normalization of the Environment and Natural Resources, in support of a proposal the Healthy Reefs for Healthy People Initiative made in September in coordination with Casa Wayuu, the Kanan Kay Alliance and the Mexican Center for Environmental Law (CEMDA). “The species of parrotfish we are trying to protect play a vital role in the survival of coral reefs because they feed on algae which otherwise deprive the coral of light and oxygen,” said AIDA attorney Camilo Thomson. “Populations of these fish have declined drastically due to habitat degradation, pollution and climate change. Studies done by the Health Reefs Initiative, among others, have shown that 60 percent of the coral reefs in the Mexican Caribbean are in either poor or critical condition.” The organizations are calling for the following species to be listed under some category of risk in Official Mexican Law 059: the stoplight parrotfish (Sparisoma viride), the rainbow parrotfish (Scarus guacamaia), the blue parrotfish (Scarus coeruleus), the midnight parrotfish (Scarus coelestinus), the queen parrotfish (Scarus vetula), the princess parrotfish (Scarus taeniopterus), the striped parrotfish (Scarus iseri), the redband parrotfish (Sparisoma aurofrenatum), the redtail parrotfish (Sparisoma rubipinne), and the yellowtail parrotfish (Sparisoma chrysopterum). The letter outlines the treaties and conventions that oblige the Mexican State to adequately fight threats to species requiring special protection—species like herbivorous fish, which are vital for the health of Caribbean reefs and other marine ecosystems. These agreements include the Convention for the Protection and Development of the Marine Environment in the Wider Caribbean Region (also known as the Cartagena Convention), the United Nations Convention on the Law of the Sea, the Convention on Biological Diversity, the Ramsar Convention, the Convention concerning the Protection of World Cultural and Natural Heritage, the Tulum Declaration, and the International Coral Reef Initiative. “The letter also mentions the Advisory Opinion on human rights and the environment issued by the Inter-American Court of Human Rights,” Thomson added. “In that decision, the Court strengthens States’ obligations to protect human rights and acknowledges the close relationship that has with environmental protection.” Despite serving as fish hatcheries and natural barriers against hurricanes—among other key functions—coral reefs are very fragile and vulnerable to climate change, the consequences of which include ocean acidification, sea level rise and algal blooms. The latter are caused by untreated or inadequately treated wastewater being pumped into the Caribbean, and other forms of marine pollution. “The most recent report from the Intergovernmental Panel on Climate Change (IPCC) warned that the warming of the planet’s average temperature by more than 1.5 degrees Celsius would result in the destruction of reefs,” explained Melina Soto, Mexico coordinator for the Healthy Reefs Initiative. “It is therefore urgent States adopt adequate measures to preserve coral reefs, and one way to do that is through the protection of herbivorous fish.” Find more information about the case here.
