Belize Reef: Endangered Paradise

The Belize Barrier Reef, the largest barrier reef system in the Northern Hemisphere, was removed from UNESCO's List of World Heritage in Danger sites in 2018. This was due to the Belizean government's moratorium on oil exploration and drilling in all of its offshore waters, protecting critical ecosystems. The reef is home to nearly 1,400 species, including endangered hawksbill turtles, West Indian manatees, sting rays, coral, and six threatened species of sharks. It is also a vital source of income for Belize, with reef-based tourism and fishing contributing an estimated $215 million to the country's GDP. While this is a positive step, the reef still faces challenges from increasing tourism, an invasion of lionfish, and pollution runoff, as well as the ongoing threat of climate change.

Oil exploration and drilling

Belize's Barrier Reef, a UNESCO World Heritage Site, was once under severe threat from oil exploration and drilling. The Belize Barrier Reef Reserve System is part of the Mesoamerican Reef System, the world's second-largest, stretching over 600 miles. It is comprised of seven protected areas, including the Blue Hole Natural Monument, and is home to nearly 1,400 species, including endangered hawksbill turtles, manatees, stingrays, coral, and six threatened species of sharks.

The Belizean government's decision to impose a moratorium on oil exploration and drilling in all offshore waters is a landmark piece of legislation that has helped safeguard this fragile ecosystem. This move has been praised by conservationists and organisations such as WWF International, who recognised the "incredible turnaround" from the reef being threatened by seismic testing for oil just eighteen months prior.

The history of oil exploration in Belize dates back to the 1930s, when Shell obtained the first exploratory license. However, World War II halted exploration, and it wasn't until the 1950s that Gulf drilled the first wildcat well. Over the years, various companies, including Shell, Gulf, Bandini Petroleum, Phillips, and more recently, Belize Natural Energy (BNE), have explored and drilled for oil in Belize. BNE discovered onshore oil in 2005 at Spanish Lookout and is currently the only company producing and exporting oil from the country.

The possibility of offshore oil drilling near the reef sparked public concern, with activists and conservation groups leading the way in pushing back against these plans. In 2011, campaigners gathered over 20,000 signatures, calling for a national referendum on oil drilling. When the government refused, activists organised their own "people's referendum," which resulted in a vast majority voting to protect the reef instead of allowing offshore oil drilling. This, along with a Supreme Court ruling that invalidated oil contracts due to inadequate environmental impact procedures, marked a turning point in the political tide.

The Belize Barrier Reef faced a critical threat from oil exploration and drilling, which could have had devastating consequences for the fragile ecosystem and the livelihoods of those who depend on it. The moratorium on oil exploration and drilling is a significant step forward in safeguarding the reef and ensuring its long-term protection.

Lack of regulation

The Belize Barrier Reef, a UNESCO World Heritage Site, was added to the endangered list in 2009 due to a lack of strong regulations and harmful industrial activities. The reef was under threat from oil exploration, rapid destruction of mangrove forests, and coastal development.

In the past, the Belizean government has been criticized for its lack of regulation regarding the protection of the reef. In 2011, it was revealed that the government had quietly sold off oil leases for the entire seabed, causing public concern for the reef to blossom. Activists pushed back, and in 2012 they gained enough signatures on a petition to force a national referendum on oil drilling. However, the government refused to issue the referendum, claiming that thousands of the signatures were illegible. This led to activists organizing their own "people's referendum," in which 96% of people chose to protect the reef instead of allowing offshore oil drilling.

The Belize Barrier Reef is an incredibly diverse ecosystem and is home to nearly 1,400 species, including endangered hawksbill turtles, West Indian manatees, sting rays, coral, and six threatened species of sharks. It is also a vital source of income for the country, with reef-based tourism and recreational activities accounting for an estimated $200 million of Belize's GDP, while commercial fishing contributes about $15 million.

In recent years, the Belizean government has taken steps to address the lack of regulation and protect the reef. In December 2017, Belize agreed to end oil exploration in its waters and began securing the region against immediate threats. In addition, the government has adopted critical regulations to protect the country's mangroves and has announced plans to phase out single-use plastics. These efforts have been praised by UNESCO, which removed the Belize Barrier Reef from its list of endangered world heritage sites in 2018.

While the Belizean government has made significant progress in protecting the reef, there are still challenges to be addressed, including increasing cruise ship tourism, an invasion of lionfish, and pollution runoff. Climate change also poses a major threat to the ecosystem, with increasing water temperatures, ocean pollution, and acidification.

Harmful coastal construction

The Belize Barrier Reef was added to UNESCO's List of World Heritage in Danger in 2009 due to the threat of irreversible damage from harmful coastal construction and oil exploration. The rapid destruction of mangrove forests and coastal development threatened to degrade the reef system, which is part of the largest reef in the northern hemisphere and home to threatened species such as sea turtles, manatees, and crocodiles.

In the case of the Belize Barrier Reef, coastal construction was a significant concern due to the lack of strong regulations and the rapid development occurring along the coast. This development threatened to destroy critical habitats and disrupt the ecosystem's delicate balance. The construction of new infrastructure, such as roads and hotels, can also bring an influx of people and increase the pressure on the reef from tourism and recreational activities.

To address these concerns, the Belizean government implemented a series of conservation measures, including imposing a moratorium on oil exploration and drilling in all offshore waters and enacting critical regulations to protect the country's mangroves. These efforts were recognized by UNESCO, which removed the Belize Barrier Reef from its List of World Heritage in Danger in 2024, acknowledging the government's visionary plan to manage the coastline.

While the removal from the endangered list is a positive step, continued vigilance is necessary to ensure that harmful coastal construction does not resume and that the reef remains protected for future generations.

Destruction of mangrove forests

Mangroves are a vital part of Belize's ecosystem, supporting biodiversity and protecting the coastline. However, their existence is under threat due to several human activities, including tourism and development.

Belize is home to three types of mangrove: red, black, and white mangroves, as well as an associate species known as Buttonwood. These mangroves cover 3.4% of Belize's land and border much of its 386-kilometre coastline and cayes. Mangroves are one of the few types of trees that can survive partial seawater submersion, and they play a crucial role in protecting the mainland from storms, flooding, and erosion. They also provide breeding grounds and shelter for a variety of birds, lobsters, crabs, and fish.

Despite legislation protecting the mangroves of Belize, their cover is decreasing due to expanding developments, including hotels and resorts. The rise in mass tourism has led to the clearing of more wetland areas. The removal of mangrove forests has direct consequences for the environment and local communities. For example, in Caye Caulker, the removal of mangrove forests has increased the vulnerability of the community to storm surges.

In addition to tourism and development, other factors contributing to the destruction of mangrove forests in Belize include shrimp farms, sugar cane plantations, and rising sea levels due to climate change. The complete inundation of mangrove forests can overwhelm their ability to filter seawater, placing them in peril.

The destruction of mangrove forests in Belize has far-reaching ecological implications. It disrupts the natural balance of the ecosystem, endangers marine life, and increases the vulnerability of coastal communities to natural disasters. The loss of mangrove forests also affects the livelihoods of locals, particularly those who depend on fishing and tourism for their income.

Belize has recently taken steps to address the destruction of its mangrove forests. In addition to imposing a moratorium on oil exploration and drilling, the government has implemented strict regulations on the cutting of mangroves. These efforts have been praised by UNESCO, which removed the Belize Barrier Reef Reserve System from its list of endangered World Heritage Sites.

Climate change

Belize's Barrier Reef, the largest in the Western Hemisphere, has been under threat from climate change. The effects of climate change, such as rising ocean temperatures and ocean acidification, have led to coral bleaching and the collapse of coral reefs.

Coral reefs are vital for the wildlife that live there and the people who rely on them for income and protection. In Belize, nearly 200,000 people, or more than half of the country's population, depend on the reef for their livelihood. The reef is also an essential natural barrier, saving Belize up to $350 million per year in avoided damage from storms and other natural disasters.

Coral bleaching occurs when the water temperature rises, disrupting the relationship between the coral animal and the algae that live inside it. The coral expels the algae, causing it to lose its colour and its primary source of nutrients. While coral can sometimes recover by taking up new algae, if temperatures remain high, the coral can become vulnerable to disease and die.

In a study published in Frontiers in Remote Sensing, scientists ranked 24 marine protected areas off the Belize coast based on the risks coral faces from rising temperatures and murky water. The study used 20 years of data from NASA's Aqua satellite to assess the vulnerability of Belize's coral reefs to bleaching and collapse due to human activity and climate change.

The effects of climate change on coral reefs are not limited to Belize. Scientists estimate that over 27% of the world's coral has been permanently lost, and at current rates of destruction, another 30% will disappear in the next 30 years. Reefs across the Caribbean have been particularly affected, and the increase in ocean temperature and acidity has made them more susceptible to deadly diseases.
