In the Gulf of Mexico, 27 coral reefs form a submarine mountain range running for miles between six islands. Hundreds of colorful fish species, sea urchins, starfish, and sea grasses share the reef with an abundance of other life forms. Fishing, sport diving, and beach tourism thrive along the coast. This is the magnificent Veracruz Reef, the largest coral ecosystem in the Gulf.
In 1992, Mexico’s government declared the Veracruz Reef System a Natural Protected Area. In 2004, it was listed as a Wetland of International Importance under the Ramsar Convention, a treaty for the protection of wetlands including reefs.
Despite the reef’s recognized significance, in 2013 the government reduced the size of the Natural Protected Area and approved a port expansion project. Local communities and organizations challenged the project's environmental permits, demanding protection of the right to a healthy environment.
On February 9, 2022, the Supreme Court of Justice of the Nation unanimously decided that the authorities violated the right to a healthy environment of Veracruz residents by authorizing the port expansion based on a fragmented environmental impact assessment. This means that the permits for the project are non-existent and that the impacts of the project on the health of the reefs must be studied again, this time in a comprehensive manner, and even the viability of the project.
The ruling is a historic precedent not only in Mexico, but for the entire region, as it allows access to environmental justice for the people neighboring an ecosystem affected by a project.

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.

Coral Reefs and the Unintended Impacts of Tourism
By Camila Cossio, former AIDA intern During my internship in AIDA’s San Jose office, I met up one day with a friend from the States for lunch. She told me about her trip visiting the beaches of Costa Rica. Everything she described sounded beautiful: the clear, blue water; hermit crabs that left their shells to eat breakfast in the early morning hours; sweet fruits that fell down onto the smooth sand; and the cool, green trees that provided shade from the hot Costa Rican sun. But her mood changed suddenly, from bliss to concern, when she explained how her co-worker swam too close to a coral reef one afternoon and badly cut his thigh. She was concerned with how unprepared their tour guide was to handle the situation, and how irresponsible it seemed that tourists were allowed – with no diving experience – to swim that close to the reefs. Leaving aside the physical dangers to humans, accidents like his, though they may seem inconsequential, have a severe impact on sensitive marine ecosystems like coral reefs. Coral reefs are a unique and complex ecosystem, vital to the health of oceans. Yet 93 percent of the reefs in Costa Rica are in danger, and tourism is a significant factor in their degradation. Tourism’s threats to corals When tourists accidently touch, pollute, or break parts of the reef, corals experience stress. The coral organisms try to naturally fight off pollutants, but this process often leads to coral bleaching – when corals lose their bright colors and become completely white. Once corals are bleached, they can no longer contribute to the biodiversity of the reef community, which depends upon symbiotic interactions between fish, invertebrates, and their habitats. Additionally, since the disruption of one ocean ecosystem gravely impacts others, sea grass and mangrove communities – shallow-water plant species vital to health of the marine ecosystem – are also severely threatened by coral stress. Another significant problem facing coral reefs is sedimentation. When solid residues are deposited into the depths of water bodies, they pollute marine ecosystems and block light needed for photosynthesis. When light is blocked, immobile coral reefs bleach and die. In Costa Rica, sources of sedimentation include dredging, logging, agriculture and coastal development driven by the tourism sector. A Reef Under Siltation Stress: A Decade of Degradation, a study by Costa Rican biologist Jorge Cortés, documents the negative impacts of tourism on coral reefs in the Cauhita region of Costa Rica. Another case study on the reefs of Bahía Culebra found that coastal development related to the tourism sector was essentially unregulated. Because of this, coral reefs in the Pacific continue to suffer. Sedimentation will continue to destroy reefs if better management principles are not enacted. In 1994 in Bahía Culebra, for example, a reef was burned due to sediments leftover from construction of a tourist center. Eighty percent of the reef was completely destroyed. Scientific literature predicts that 50 percent of all coral reefs in Latin America are at risk of degradation in the next five to 10 years. Studies show that, globally, 30 percent of reefs are already seriously damaged and 70 percent of all coral reefs are expected to disappear by 2030 if corrective measures are not taken to stop the negative anthropogenic impacts on coral reef communities. Building a future for coral reefs Sustainable tourism is a great concept on paper, but hard to enforce in reality. Construction of coastal properties requires waters to be dredged. It creates pollutant runoff from roads and parking lots and airports. Sewage is dumped into the ocean, and more intensive agriculture to support all the people increases sedimentation. Although it’s difficult for an individual to stop massive projects like these, it’s easy to take small but powerful steps: not picking up wildlife for souvenirs (shells, coral rubble, plants); being conscious of what you bring with you – reusable water bottles instead of plastic bottles, a backpack for your trash in case there isn’t an area nearby to dispose of waste properly; taking the bus instead of a car; and – if possible – doing research on the hotels or hostels in which you stay. Many coastal hotels dump their graywater – wastewater from laundry, cooking, and non-toilet related household processes – into the ocean, contributing to sedimentation and contaminating coral reef ecosystems. It’s important to be aware that many land-based activities may directly harm the marine eco-system. Being an environmentally friendly tourist is not about being perfect, but individual actions, though they may seem small, really can have a big impact.

How can we save coral reefs?
By Haydée Rodríguez When I tell people I live in Costa Rica, they imagine my home on the beach, facing the ocean, waves rolling in from the endless horizon. In reality, I live in a city like any other, one hour from the Pacific coast and three from the Caribbean. Although my life hasn’t exactly been a tropical vision of paradise, I’ve been in love with the ocean since I was a girl. That love has only deepened the more I came to understand the mysteries of the sea, the services it provides and the marvelous creatures that call it home. Of all the species that live in the sea, corals are among my favorites. Thanks to my career at AIDA, I have been able to both learn a lot about these tiny animals, and work to identify effective ways to protect them. Many people don’t know about the incredible connection we have with corals. It’s a connection that exists even for those of us who don’t have the privilege of living by the sea. What are corals and what do they do for us? Although at first glance they look like large rocks, corals are actually living organisms with an exoskeleton. They have a mutualistic relationship with photosynthetic algae called zooxanthellae, which are responsible for their brilliant coloring. The algae use sunlight to produce food and some of the nutrients that the corals need to survive. In exchange, the corals provide the algae with a protected environment. A group of corals forms a reef, a highly biodiverse ecosystem, widely known as the jungle of the sea. Coral reefs provide many benefits to humanity: Reefs are spawning grounds for many varieties of fish—the fish you eat are linked, in one way or another, with a coral reef. Reefs are natural shock absorbers that protect coastal communities from storms and hurricanes. Reefs are tourist destinations that generate important national income: one square kilometer of coral reef provides services valued at up to $600,000 a year, according to the United Nations. The bad news is that these benefits could be lost if we don’t act now to preserve coral reefs. It’s estimated that 60 percent of the world’s coral reefs could disappear by 2030. That would mean that our children may enjoy them for only a brief time, and our grandchildren may know them only from photographs in their science and history books. What are the threats and how can we help fight them? Unsustainable fishing methods, such as trawling, which destroys any coral in its path. Before eating or buying seafood, it’s worth asking how it was fished. Becoming responsible consumers is our right and our obligation. We must demand in restaurants and grocery stores products that have been taken from the sea without harming corals or other species of importance. Inadequate tourism practices harm coral reefs. When exploring the wondrous corals reefs, snorkelers and divers must avoid touching or stepping on them at all costs. We must remember that corals are living creatures, which our weight and the equipment we carry into the sea can harm. When we buy souvenirs like necklaces and crafts, we should reject products that use or incorporate corals. We do not need corals to decorate our homes or bodies, but the ocean needs them to maintain its equilibrium. A recent study found that, when they come into contact with the ocean, sunscreens that contain oxybenzone (a chemical compound) could, even in low concentrations, damage the DNA of corals, deforming them and eventually causing death. We must avoid using this type of product, and instead use safe sunscreens and clothing to protect us from the sun. Here is a list of sunscreens that are safe for corals. The fertilizers used on crops leech into rivers and eventually reach the ocean, severely harming corals by increasing the production of algae, which in large quantities block the sun and prevent corals from receiving nutrients. We must opt for fruits and vegetables grown organically and demand responsible agriculture. Improving legal protection of coral reefs Another important way of saving coral reefs is by seeking change in our countries. We must urge our governments to improve the laws protecting these sensitive creatures. At AIDA, we have recently published A Guide to International Regulatory Best Practices for Coral Reef Protection. The document contains ideas to strengthen laws and promote the conservation of coral reefs around the world. I invite you to share the guide with decision-makers in your country. Or if you prefer, send me ([email protected]) the contact information of people who may be interested in implementing the recommendations contained within, and I will send them the guide directly. Corals play a more important role in our lives than many of us understand, and their future is in our hands. We must save coral reefs to ensure that our children and our grandchildren can enjoy the many benefits of these wondrous creatures.
