“Fracking” is short for hydraulic fracturing, a process used to extract oil and natural gas from historically inaccessible reservoirs.
Fracking is already widespread in the global North, but in Latin America, it is just beginning. Governments are opening their doors to fracking without understanding its impacts and risks, and without consulting affected communities. Many communities are organizing to prevent or stop the impacts of fracking, which affect their fundamental human rights. But in many cases they require legal and technical support.
What exactly is fracking, and what are its impacts?
A straight hole is drilled deep into the earth. Then the drill curves and bores horizontally, making an L-shaped hole. Fracking fluid—a mixture of water, chemicals, and sand—is pumped into the hole at high pressure, fracturing layers of shale rock above and below the hole. Gas or oil trapped in the rock rises to the surface along with the fracking fluid.
The chemical soup—now also contaminated with heavy metals and even radioactive elements from underground—is frequently dumped into unlined ponds. It may seep into aquifers and overflow into streams, poisoning water sources for people, agriculture, and livestock. Gas may also seep from fractured rock or from the well into aquifers; as a result, water flowing from household taps can be lit on fire. Other documented harms include exhausted freshwater supplies (for all that fracking fluid), air pollution from drill and pump rigs, large methane emissions that aggravate global warming, earthquakes, and health harms including cancer and birth defects.
AIDA’s report on fracking (available in Spanish) analyzes the viability of applying the precautionary principle as an institutional tool to prevent, avoid or stop hydraulic fracturing operations in Latin America.

Groups submit arguments supporting government’s case for maintaining wildlife refuge. Panama City, Panama — Today, on International Mangrove Day, two civil society organizations announce their legal support for the government of Panama in a lawsuit brought by developers challenging the protected status of Panama Bay. The groups, the Interamerican Association for Environmental Defense (AIDA) and the Centro de Incidencia Ambiental (CIAM), submitted legal briefs detailing national and international legal arguments for upholding environmental protections established by the government in 2009 through a resolution issued by the environmental authority in Panama. The developers who are contesting the law, Panama Bay Development and Compañia Lefevre, are seeking to open the area to development of vast tourism complexes. Extensive tourism in the area would bring devastating environmental impacts to the sensitive ecosystem. The Panama Bay coastline is ringed with miles of pristine mangroves, which provide critical breeding ground for species relied upon by Panama’s fishing industry. Each kilometer of mangrove-covered coastline generates about $100,000 USD for Panama annually. Mangroves also help protect Panama from the effects of global climate change by buffering the coast from increasingly powerful tropical storms and by storing carbon from the atmosphere in their roots. A mangrove forest can sequester 50 times more carbon than a tropical forest of the same size, making mangroves a conservation priority if countries wish to halt catastrophic climate change. The protected area of Panama Bay is roughly 211,000 acres, slightly larger than the land area of New York City. Panama Bay is one of the earth’s most biodiverse places and is an essential habitat for migratory birds and threatened species such as jaguars and loggerhead turtles. “In the face of ever more powerful and dangerous climate-change-driven tropical storms, destroying coastal mangroves is one of the worst things a country like Panama could do,” said Anna Cederstav, Ph.D., staff scientist and co-director of AIDA. According to Sandra Moguel, an attorney for AIDA in Mexico, “Article four of the Constitution of Panama requires the observance of the rules of international law throughout the territory of that country. Obligations under the Ramsar Convention on Wetlands of International Importance and the Convention on Biological Diversity, both of which have been ratified by Panama, should thus be taken into consideration in deciding the challenge against the natural protected area.” "The creation or declaration of a protected area does not constitute expropriation. What it does is protect and guarantee the right to a healthy environment contained in the Panamanian Constitution” said Maria Acuña, CIAM´s legal advisor.

Mexican Constitution protects human rights
On June 9, 2011, Mexico rewrote history. The Mexican Congress approved revisions that expressly recognize human rights in the national constitution for the first time. The new language requires all authorities to adhere to international human rights treaties Mexico is a signatory to when those treaties are more expansive than the "individual guarantees" currently on the books. As modified, Article 1 of the constitution now recognizes human rights in general and incorporates international law. This means groups such as AIDA and communities in Mexico will have better legal tools for defending the right to a healthy environment or clean drinking water. Or, for example, because indigenous communities’ right to free, prior, and informed consent is granted in international law, Mexico will now have to recognize this right. Moreover, although the Mexican constitution already recognized some rights, enforcement has been difficult. The revision provides additional legal tools and thus raises hopes for enhanced protection of those rights. These constitutional changes came after a four-year process initiated by the UN Office of the High Commissioner for Human Rights in Mexico, and involving academics, nongovernmental organization, and independent experts. AIDA contributed by evaluating existing legal tools for protecting human rights as well as international legal obligations. In 2008, the Mexican Congress started considering the human-rights-related constitutional revision, which was finally partially approved in June, 2011. While the Mexican Congress and government should be applauded for its vision, the constitutional change’s effectiveness remains to be seen. Recognizing human rights is only the first step, and the new commitment will mean little without compliance. In coordination with our allies in the country, AIDA will monitor Mexican cases to ensure enforcement of this profound advancement and improved protection of the right to a healthy environment.
