Belize's Battle With Climate Change: Understanding The Contributors

Belize, a small state on the Caribbean Sea, is vulnerable to climate change. The country's low-lying terrain and location in the path of Atlantic storms make it susceptible to hurricanes, flooding, and sea level rise. Rising sea temperatures are causing coral bleaching and reduced fish catch, threatening local livelihoods and food security. Belize's economy, heavily reliant on agriculture, fisheries, and tourism, is being impacted by more intense and frequent storms. Climate change adaptation and mitigation efforts are crucial, and the government has implemented projects like the Marine Conservation and Climate Adaptation Project to strengthen the resilience of the Belize barrier reef and support sustainable livelihoods for coastal communities.

Sea temperatures rising, causing coral bleaching and reduced fish catch

Belize's extensive barrier reef system is a vibrant marine environment that supports thousands of animal and plant species, as well as the country's largest industry, tourism. However, climate change poses a significant threat to this delicate ecosystem, with rising sea temperatures causing coral bleaching and reduced fish catch.

In 1998, Belize recorded the highest sea surface temperatures ever, which led to severe bleaching of corals. This thermal anomaly caused a mass mortality event of scleractinian corals on lagoonal reefs, marking the first time a Caribbean coral population collapsed entirely from bleaching. The event was unprecedented in the last 3,000 years, according to cores extracted from the Belizean reefs.

Coral bleaching occurs when coral colonies expel their symbiotic algae due to physiological stress from high temperatures and/or high solar radiation. While some coral colonies can recover their coloration after partial mortality, others suffer catastrophic levels of coral mortality, as seen in the central Belizean lagoon. The once-abundant lettuce coral Agaricia tenuifolia experienced almost total mortality at all depths in the lagoon.

The impact of rising sea temperatures on coral reefs has significant implications for Belize's fisheries. Coral reefs provide essential habitats and breeding grounds for many marine species, and their degradation can lead to reduced fish populations and catch for Belize's fishing industry, which provides 41% of national employment.

To address these challenges, Belize has developed several climate policy frameworks, including the National Climate Resilience Investment Plan and the National Climate Change Policy, Strategy, and Action Plan. Additionally, the Ministry of Forestry, Fisheries & Sustainable Development is responsible for natural resources preservation and is the focal point for domestic and global climate action in the country.

Intense and frequent storms

Belize is highly vulnerable to the impacts of intense and frequent storms. The country is situated on the Yucatan Peninsula in Central America, bordering the Caribbean Sea, and is considered a Small Island Developing State. Its low-lying terrain exacerbates the effects of flooding and sea level rise, which are often caused by storms and hurricanes.

Belize is prone to hurricane impacts as it lies in the direct path of the majority of Atlantic storms. The country's wet season, lasting from May to October, brings the risk of tropical cyclones, particularly during La Niña years. The 2020 Atlantic hurricane season was particularly severe, with a record 30 named storms. These storms can cause extensive damage through flooding, wind, and storm surges, with Belize City being especially vulnerable.

The country's barrier reef and mangrove ecosystems play a crucial role in protecting Belize's coastal communities from these intense storms. The reef system, including the Great Blue Hole, acts as a natural defence mechanism, buffering the impact of storm surges and hurricanes. However, climate change poses a significant threat to the health and resilience of these ecosystems.

Rising sea temperatures contribute to coral bleaching, which weakens the coral skeletons that form the structure of the barrier reef. This loss of coral coverage reduces the protection offered to coastal communities from strong storms. Additionally, the increasing frequency and intensity of storms further damage the reef, creating a cycle of negative impacts.

To address these challenges, the Government of Belize, with support from the World Bank, implemented the Marine Conservation and Climate Adaptation Project (MCCAP). This project aims to strengthen the climate resilience of the Belize barrier reef and help coastal communities adapt to a changing climate. Conservation efforts, vocational training, and educational initiatives are all part of the strategy to mitigate the impacts of intense and frequent storms on Belize's vulnerable ecosystems and communities.

Country's low-lying terrain exacerbates flooding and sea level rise

Belize is a small Central American nation located on the eastern coast of the Yucatán Peninsula. It is bordered by Mexico to the north, Guatemala to the west and south, and the Caribbean Sea to the east. The country has a diverse landscape, ranging from mountainous regions in the south to low-lying coastal areas in the north.

Belize's low-lying terrain, particularly in the northern regions, makes it vulnerable to the impacts of climate change, specifically flooding and sea-level rise. The country's flat and swampy coastal plain, which includes areas like Belize City, sit at or slightly below sea level. This low elevation exacerbates the effects of flooding during heavy rains and storms, as well as the long-term impacts of rising sea levels.

The country's topography, with its low-lying areas and intricate networks of rivers, creeks, and lagoons, has played a significant role in its historical geography. The Belize River, for instance, has been a vital artery for commerce and communication. However, the same low-lying terrain that has supported human settlement and economic activities is now a source of heightened vulnerability to climate change.

Belize's geographic features, including its coastline, inlets, lagoons, and offshore islands, are integral to its economy, particularly the tourism and fishing industries. The Belize Barrier Reef, the second-longest in the world, acts as a natural defence against storm surges and hurricanes, providing some protection to the country's low-lying areas. However, the combination of rising sea levels and frequent natural disasters, such as hurricanes and tropical storms, poses a significant threat to Belize's low-lying terrain.

The impacts of climate change, including more frequent and intense storms and flooding, have severe consequences for Belize's infrastructure, economy, and population. The country's vulnerability to these events is further exacerbated by its low-lying terrain, which increases the risk of flooding and the potential for more devastating impacts from sea-level rise.

Agriculture, fisheries, and forestry sectors are vulnerable

Belize is a small island developing state that is vulnerable to the impacts of climate change due to its low-lying terrain, which exacerbates the effects of flooding and sea-level rise. The country is also susceptible to hurricanes, storms, and associated flooding, wind damage, and storm surges, particularly in Belize City. The agriculture, fisheries, and forestry sectors, which contribute significantly to the national economy, are especially at risk.

The agriculture sector in Belize is the main foreign exchange earner, contributing 35% of the national Gross Domestic Product (GDP). Climate change poses a significant threat to this sector through increased temperatures, changing rainfall patterns, and more frequent and intense extreme weather events. These impacts can disrupt crop production, reduce yields, and impact the livelihoods of farmers and rural communities. Additionally, the country's low-lying coastal regions are vulnerable to sea-level rise and storm surges, which can result in saline intrusion and further damage agricultural lands.

The fisheries sector in Belize is also vulnerable to climate change. Sea-level rise, storm surges, and rising sea surface temperatures threaten the country's marine resources and fisheries, which are crucial for food security and tourism. Climate change can disrupt fish migration patterns, breeding cycles, and habitat availability, impacting fish stocks and the livelihoods of fishers. Additionally, the increased frequency and intensity of storms and hurricanes can damage fishing infrastructure and equipment, further affecting the sector's resilience.

Belize's forestry sector is closely linked to the country's efforts to preserve and protect its natural resources and environment. The country boasts one of the largest barrier reefs in the western hemisphere, which acts as a natural defence against storm surges and hurricanes. However, climate change-induced events such as hurricanes and storms can damage forest ecosystems, leading to loss of biodiversity, habitat destruction, and increased vulnerability to other climate change impacts. Additionally, the rise in extreme temperature events can contribute to forest fires, further degrading forest resources.

The vulnerability of these sectors to climate change has economic, social, and environmental implications for Belize. The country has recognised the need to enhance adaptation planning and increase climate resilience, particularly in the coastal zones and fisheries sector. Efforts are being made to improve climate data gathering, monitoring, and dissemination, as well as to strengthen communication networks for appropriate climate response. However, barriers such as insufficient technological capacity, lack of finance, and the need for increased community education and awareness remain challenges to be addressed.

Climate change impacts tourism

Belize is a small state situated on the Caribbean Sea, with a moist tropical climate. The country is particularly vulnerable to the impacts of climate change due to its low-lying terrain and exposure to hurricanes, storms, flooding, and sea level rise. Climate change is expected to have significant effects on Belize's key economic industries, including agriculture, fisheries, and, notably, tourism.

Tourism is a major contributor to Belize's economy, with travel and tourism contributing nearly 45% of the country's GDP. The country's natural attractions, such as its renowned barrier reef system and vibrant marine environments, are a significant draw for visitors. However, these very attractions are under threat due to climate change.

Sea temperature rises have led to coral bleaching, which not only impacts the health of the reef but also reduces fish catch, affecting local livelihoods and the appeal of the country for diving tourists. Warmer waters and more intense and frequent storms also impact the marine life that relies on these ecosystems, further reducing the appeal for tourists.

To combat these threats, the Government of Belize, with support from the World Bank, implemented the Marine Conservation and Climate Adaptation Project (MCCAP). This project aimed to strengthen the climate resilience of the Belize barrier reef and promote sustainable and alternative livelihoods for coastal communities. By increasing protections and restoration efforts, as well as raising public awareness about climate change, MCCAP sought to preserve Belize's natural attractions and support the sustainability and growth of its tourism industry.

MCCAP's integrated approach to climate adaptation included vocational training in various sectors, including tourism. This training equipped locals with the skills to diversify their livelihoods beyond fishing and contribute to conservation efforts. By involving the community in these efforts, Belize is working to safeguard its natural attractions and, in turn, protect the tourism industry from the impacts of climate change.
