Cabo Pulmo Reef, a 20,000-year-old ecological treasure in Baja California Sur, Mexico, hosts many of the 800 marine species in the Sea of Cortez.
Overfishing almost killed it in the 1980s. But the Mexican government intervened in 1995 to declare it a national park. Since then, the reef has grown, and the surrounding ecosystem has prospered.
Developers repeatedly try to build enormous tourist resorts at Cabo Pulmo. The proposed resorts typically include tens of thousands of hotel rooms, golf courses, an airport, sports clubs, and more—and require new housing development for thousands of employees.
Coral reefs like Cabo Pulmo are extremely vulnerable to the impacts of such poorly planned development. Sewage and wastewater runoff cause a surge in the growth of algae that blocks sunlight, causing the reef to bleach and die.
Fertilizers, herbicides, and pesticides from golf courses contaminate ocean currents and upset the delicate ecological balance of the area. Boating, fishing, and diving stress and break reefs, too.
In an area where water is scarce, tourism infrastructure projects could overexploit aquifers that are already suffering the impacts of climate change.
AIDA's work has been instrumental in ensuring the survival and health of Cabo Pulmo's ecosystems. We continue monitoring the situation and working with national partners to make legal protections for the reef stronger and permanent.

Six advances for Latin America’s reefs in 2018
In 2018, we joined people and organizations around the world in celebrating the International Year of the Reef. AIDA was part of a global movement to increase awareness of the value of reefs and the threats they’re facing. To advance reef conservation in the Americas, we took part in a variety of legal actions to protect reefs in Mexico and the Caribbean. As always, we’re proud to celebrate the small victories we’ve achieved on the road to environmental justice in 2018. Together with our supporters and allies we: Supported a case in defense of the Veracruz Reef In February, we presented an amicus brief in support of an amparo filed by local residents against the expansion of the Port of Veracruz. We outlined how Mexico’s approval of the project in 2013 violated the nation’s international environmental and human rights commitments. Just a year earlier, the government had reduced the area of the reef system, changing its boundaries to make the project viable. At the time of authorization, adequate scientific information was not available to understand how to avoid damaging the reefs and protect the services they provide to the people of Veracruz. To raise awareness of the issue, we also co-produced a documentary, Battle for the Reefs of Veracruz. Alerted the Ramsar Convention to threats to Puerto Morelos Reef We sent an Urgent Alert to the Secretariat of the Ramsar Convention, alerting them to the threats to Puerto Morelos Reef National Park, a national protected area and Wetland of International Importance. Together with a coalition of civil society organizations, we solicited a visit of international experts to evaluate the risks facing the site, particularly changes in land use in coastal ecosystems due to massive and unsustainable tourism development. Created a Working Group on Threats to Mexico’s Wetlands In May, the Working Group on Threats was created within the National Wetlands Committee, which AIDA helped create in order to motivate Mexico to comply with its obligations to protect at-risk wetlands of international importance. Within the framework of this Group, efforts are being made to strengthen national actions to protect Ramsar ecosystems, including reefs and the herbivorous fish that make their home in them. Supported the protection of 10 species of parrotfish in Mexico’s Caribbean In October we presented a letter of support outlining international environmental and human rights arguments for the inclusion of 10 species of parrotfish on Mexico’s national list of at-risk species. While the inclusion has been acknowledged and accepted, official confirmation is expected early this year. Our efforts supported a proposal of the Health Reefs Initiative that seeks to legally protect parrotfish species, which are critical to maintaining a healthy coral reef ecosystem. Parrotfish and other herbivorous fish feed on algae that compete with corals for light and oxygen, thus enabling the reef to flourish. Helped Establish a Working Group on Corals in Costa Rica In coordination with the Ministry of Environment, we helped organize a working group of academic experts, members of civil society and competent governmental authorities that will propose comprehensive solutions to the problems facing the country’s coral ecosystems. Together we will work to ensure integral solutions to protect Costa Rica’s coral reefs. Supported a Working Group on Herbivorous Fish in Guatemala In coordination with the Healthy Reefs Initiative, academics from San Carlos University and members of the government, we’ve supported the creation of a working group to draft a technical-scientific document that outlines the information necessary for a ministerial decree to prohibit the fishing of herbivorous fish in the Guatemalan Caribbean and, thus, protect the nation’s reefs.

To keep corals healthy, we must protect herbivorous fish
We all know coral reefs are fragile environments, highly vulnerable to climate change and pollution. But did you know they also had to compete for light and oxygen with the tiny macro-algae that cover their surface? That’s why some of corals' best friends are herbivorous fish—species like parrotfish and surgeonfish that feed on algae, helping to keep corals healthy. But in the Caribbean, unsustainable fishing practices are causing a decline in populations of parrotfish (and other herbivorous fish), putting the health of corals at risk. That’s why, in AIDA’s marine program, we’re launching a large-scale project dedicated to the conservation of herbivorous fish throughout Latin America—focused on the nations of Colombia, Costa Rica, Guatemala, Honduras, Mexico and Panama. Herbivorous fish conservation The parrotfish is one of the most important fish living in coral reefs. They spend most of the day nibbling on corals, cleaning algae from their surface. They also eat dead corals—those bits and pieces that protrude from the reef—and later excrete them as white sand. A key element to maintaining sustainable fisheries is catching only adult fish—those that have already matured and reproduced. But in the Caribbean right now, people are fishing juvenile parrotfish. Though not a commercial species, parrotfish are being captured because they’re some of the only fish left in the reef. The irresponsible nature of commercial fishing in the region has caused a drastic decline in both commercial and herbivorous fish. “A key element of maintaining a sustainable fishery is catching only adult fish, which have already matured and reproduced. But what’s happening in the Caribbean is the fishing of young parrotfish,” explained Magie Rodríguez, AIDA marine attorney. Most fishing is done with gillnets and hooks, which cause high levels of by-catch—unwanted populations of marine species caught in commercial fishing. Harpoons and traps are also used, which prevent younger, smaller fish from escaping and continuing their life cycle. Surgeonfish and damselfish are two other herbivorous fish—both small and quite beautiful—falling victim to irresponsible fishing practices. Their popularity in tropical home aquariums has led to a decline in their wild populations. Remember Dory, from Finding Nemo? She was a surgeonfish, and the movie’s popularity led to an increased demand for her species in aquariums. What the movie didn’t tell you is that the surgeonfish’s small, sharp teeth are highly adept at chewing algae, preventing the plantlife from essentially choking coral reefs of oxygen and light. Conservation strategies AIDA’s project for the conservation of herbivorous fish in the Caribbean is in its initial phases. Our objective is the implementation of diverse strategies, across the six Latin American nations, to protect these fish and, by extension, the reefs they call home. “To restore the balance of the coral ecosystem, it’s necessary to achieve the recovery not just of herbivorous fish populations, but also of commercial species,” Rodríguez said. So we’re talking not just about fishing bans, but also about the general adoption of sustainable fishing tools that take into account the tourism potential of coral reefs. The project will also contemplate adequate wastewater management strategies, consumer education, and collaboration between governments, NGOs, universities and scientists. Corals are, among other things, a source of economic income and food for coastal communities that live from fishing and tourism. Plus, they are natural barriers against storms and hurricanes. “Corals do a lot for us and we have to take care of them,” Rodríguez added. “We’ve come to find that the best thing we can do to keep corals healthy is to protect the herbivorous fish that call them home.”

In search of legal protection for Mexico’s reefs
From the coasts of Baja California to the shallows of the Caribbean, Mexico is home to an incredible array of reefs. The coral and rocky reefs found throughout the country are sources of food and potentially life-saving genetic material. They protect people on the coasts from the impacts of storms and hurricanes, stimulate tourism, and provide shelter for a wide variety of plants and animals. Despite their inherent value, Mexico does not yet have an overarching law for reef protection. This vital task is instead governed by a variety of legislation and by international treaties that establish the country’s obligations to preserve these valuable ecosystems. Climate change is one of the most serious threats to reefs. Oceans are becoming warmer and more acidic, conditions that reduce reefs’ capacity to grow and repair themselves. In addition, warmer water disperses the algae that corals feed on, leaving the corals weakened and at risk of death. This month, the Mexican Senate’s Special Climate Change Commission decided to do something about the threats facing corals. They convened a series of meetings to promote the creation of a legislative instrument aimed exclusively at protecting the nation’s many reefs. I participated in these meetings as a representative of AIDA, alongside our colleagues from Wildcoast and scientists, academics, and community members who benefit from the services reefs provide. We drew the Senate’s attention to the serious threats facing reefs, and to the urgency of applying the precautionary principle to guarantee the human right to a healthy environment, which is at risk due to the lack of adequate regulations for reef conservation. To guarantee this right and to protect the oceans against climate change, Mexico has signed international treaties including the American Convention on Human Rights, the Paris Agreement on Climate Change, the Ramsar Convention on Wetlands, and the Inter-American Convention for the Protection and Conservation of Sea Turtles. The Veracruz Reef, an emblematic case Reefs around the country are also being threatened by inadequately planned coastal infrastructure and insufficient environmental impact assessments. This is the case with the expansion of the port of Veracruz, a project that endangers the Veracruz Reef System, the largest coral ecosystem in the Gulf of Mexico. The site was declared a Natural Protected Area in 1992, a priority region for the National Commission for the Knowledge and use of Biodiversity in 2000, a UNESCO biosphere reserve in 2006, and a Ramsar site. Even so, the government reduced the size of that area in 2013 to make way for the port project, violating international conventions such as the Ramsar Convention, under which the Veracruz reef is recognized as a Wetland of International Importance. Learn more about the case in the following video: Hope for Mexico's Marine Heritage We are confident that the Senate initiative will bear fruit and that Mexico will develop a law for the protection of its reefs, and that it will be born from a transparent and participatory process to which we will continue to contribute. To learn more about the topic, see our report The Protection of Coral Reefs in Mexico: Rescuing Marine Biodiversity and its Benefits for Humanity.
