The Impact Of Climate Change On Belize: A Small Country's Big Challenges

Belize is highly vulnerable to the effects of climate change. As a low-lying coastal country, it is particularly susceptible to natural disasters, rising sea levels, and temperature changes, which impact its ecosystems, agriculture, tourism, and fisheries sectors. Climate change has also led to an increase in the frequency and severity of natural disasters such as floods, hurricanes, and coral bleaching, causing property destruction and affecting access to clean water, food, and homes, with disadvantaged families bearing the brunt of these impacts.

Belize Barrier Reef Reserve System

The Belize Barrier Reef Reserve System (BBRRS) is a UNESCO World Heritage Site, inscribed in 1996. It is the largest reef complex in the Atlantic-Caribbean region and the second-largest reef system in the world. The BBRRS is comprised of seven protected areas, which make up 12% of the entire reef complex. These areas include:

• Bacalar Chico National Park and Marine Reserve
• Blue Hole Natural Monument
• Half Moon Caye Natural Monument
• South Water Caye Marine Reserve
• Glover's Reef Marine Reserve
• Laughing Bird Caye National Park
• Sapodilla Cayes Marine Reserve

The BBRRS is an outstanding natural system that extends from Mexico in the north to near the Guatemalan border in the south. It is comprised of the largest barrier reef in the northern hemisphere, offshore atolls, several hundred sand cays, mangrove forests, coastal lagoons, and estuaries. These seven sites illustrate the evolutionary history of reef development and provide a significant habitat for threatened species, including marine turtles, manatees, and the American marine crocodile. The reef is also home to a diverse array of plant and animal life, including 70 hard coral species, 36 soft coral species, and hundreds of invertebrate species.

The BBRRS is facing multiple impacts of climate change, including coral bleaching, more severe storms, and rising sea levels. According to the IPCC, the increase in sea surface temperature and dissolved CO2 levels in the oceans will be the most serious threats to coral reefs in the 21st century. Coral bleaching has already caused long-term damage to many coral reefs worldwide, and over 40% of Belize's coral reef has been damaged since 1998. The BBRRS is also vulnerable to other natural disasters such as hurricanes, flooding, and coastal erosion, which are expected to intensify with increasing weather volatility and sea temperature rises.

To address these challenges, Belize has implemented various measures, including the Resilient Reefs Initiative (RRI), which aims to build the country's resilience through community knowledge, livelihood diversification, and balancing conservation with commercial and local use of the reef. In addition, Belize has executed a US$364 million Blue Bond for ocean conservation and adopted a permanent oil moratorium to protect its reefs. These efforts demonstrate Belize's commitment to safeguarding its remarkable marine ecosystem and addressing the impacts of climate change.

Natural disasters and climate change

Belize is highly vulnerable to the effects of natural disasters, climate change, and the economic devastation that follows. The country's low-lying terrain makes it susceptible to flooding and sea-level rise, and it is also at risk of extreme temperature events. Climate change has intensified the impact of natural disasters, causing poverty in Belize, particularly due to the destruction of property, and reduced access to clean water, food, and homes, affecting disadvantaged families the most.

Belize already faces hurricanes, flooding, and coral bleaching, with these impacts expected to worsen due to increased weather volatility and rising sea temperatures. The country is economically dependent on natural resources, and the rise in sea levels and temperature changes impacts its natural ecosystems, agricultural systems, and other sectors such as tourism and fisheries. Climate change has increased the frequency and severity of natural disasters in Belize, including floods, hurricanes, and coral bleaching.

The Belize Barrier Reef Reserve System, a UNESCO World Heritage Site, is facing multiple threats due to climate change. These include coral bleaching, severe storms, and rising sea levels. The increase in sea surface temperature and dissolved CO2 levels in the oceans pose a significant threat to coral reefs. Climate change-related impacts, such as sea-level rise, increased sea temperature and acidification, as well as increased storm frequency and intensity, have already caused long-term damage to many coral reefs worldwide.

To address these challenges, Belize has implemented various initiatives and policies. The Resilient Reefs Initiative (RRI) aims to build the country's resilience by harnessing community knowledge, diversifying livelihoods, and balancing conservation with commercial and local use of the reef. The country has also executed a US$364 million Blue Bond for ocean conservation. Additionally, Belize has partnered with organizations such as the Great Barrier Reef Foundation and the Nature Conservancy's Reef Resilience Network to strengthen its climate adaptation efforts.

Economic devastation

Belize is a low-lying coastal country that is highly vulnerable to the effects of climate change and natural disasters. The country is also economically dependent on natural resources, which means that rising sea levels and temperature changes impact its ecosystems, agriculture, tourism, and fisheries. As a result, Belize is susceptible to economic devastation.

One of the most significant ways that climate change affects Belize's economy is through the destruction of property and the loss of livelihoods. More frequent and severe natural disasters, such as floods, hurricanes, and coral bleaching, lead to the destruction of homes, businesses, and infrastructure. This, in turn, results in financial losses, displacement of people, and a decrease in economic productivity. For instance, the Belize Barrier Reef Reserve System, which supports the country's largest industry, tourism, is facing multiple impacts of climate change such as coral bleaching, severe storms, and rising sea levels.

Climate change also affects Belize's agricultural sector, which is vital to the country's economy. Droughts and changes in temperature and water availability can reduce crop yields, impacting both small-scale farmers and large-scale agricultural businesses. This can lead to food shortages, increased food prices, and a decline in agricultural exports, further exacerbating the economic challenges faced by the country.

In addition, the increase in sea surface temperature and ocean acidification due to climate change poses a significant threat to Belize's marine ecosystems, particularly its coral reefs. Coral bleaching, caused by the expulsion of symbiotic algae that live in the coral, can lead to long-term damage and even mortality of the coral. This not only affects the biodiversity and ecological balance of the reefs but also impacts the fishing industry, which is an important source of income for many coastal communities in Belize.

The economic devastation caused by climate change in Belize is further exacerbated by the country's vulnerability to extreme temperature events and storms. Belize City, in particular, is at risk due to its low-lying terrain, which amplifies the effects of flooding and sea-level rise. The impact of these natural disasters on the country's infrastructure, transportation, and communication networks can be devastating, hindering economic growth and development.

Overall, the economic impacts of climate change in Belize are far-reaching and devastating. The country's dependence on natural resources and its vulnerability to natural disasters amplify the effects of climate change, leading to property destruction, loss of livelihoods, and a decline in key sectors such as agriculture, tourism, and fisheries. Addressing these challenges requires a combination of adaptation measures, policy reforms, and global efforts to mitigate climate change.

Sea level rises and temperature changes

Belize is highly vulnerable to the effects of climate change, particularly sea level rises and temperature changes. The country's low-lying terrain, flat coastline, and position in the path of Atlantic storms make it susceptible to flooding, sea level rise, and storm surges. The Caribbean Community Climate Change Centre (CCCC) predicts that by 2100, substantial portions of the country could be underwater, with most of Belize City submerged. The rising sea levels will also impact the country's water supply, as inland waters become more saline.

The rate of sea level rise in Belize is currently about 3 millimetres per year, which may not seem significant, but it accumulates over time. According to Dr. Kenrick Leslie of the CCCCC, each millimetre of rise translates to a metre of land being submerged. This could have major implications for infrastructure, including airports and buildings on the cayes (small, sandy islands).

In addition to the gradual rise in sea levels, Belize is also at risk of extreme weather events and temperature changes. The mean annual temperature in Belize has increased by 0.45°C since 1960, with an average rate of 0.10°C per decade. This has led to an increase in the frequency of hot days and nights, and a decrease in cold days and nights. The El Niño phenomenon contributes to warmer conditions, while La Niña produces wetter conditions and tropical cyclones.

The Belize Barrier Reef Reserve System, a UNESCO World Heritage Site, is also facing the impacts of climate change. The reef system is threatened by rising sea levels, increased sea temperatures, acidification, and more frequent and intense storms. One of the most serious consequences is coral bleaching, which has already caused long-term damage to coral reefs worldwide.

To address these challenges, Belize has taken several adaptation measures. The country has signed the Paris Agreement, committing to addressing global warming and sea-level rise. Additionally, Belize has implemented renewable energy projects and is working on building climate change resilience through initiatives like the Resilient Reefs Initiative, which aims to balance conservation with commercial and local use of the reef.

Coral bleaching

Belize's coral reefs have been severely affected by coral bleaching. Within the Belize Barrier Reef Reserve System, the second largest in the world, the bleaching stress level increased from 1.7 between 1985-2014 to a severe level of 3 in 2014-2017. This near-doubling of bleaching in just three years poses a serious threat to the reefs. The Mesoamerican Barrier Reef, located between the Yucatan Peninsula in Mexico and Belize, has been transformed from vibrant to dull due to elevated temperatures caused by climate change.

The impact of coral bleaching on the reefs of Belize is significant. The reefs support thousands of species and drive Belize's largest industry, tourism, which comprises over 38% of the country's GDP and provides 50,000 jobs. The loss of the reefs would thus have a devastating impact on the economy and the livelihoods of the local people who depend on reef tourism.

Furthermore, the reefs act as natural barriers that protect the coast from waves and storm surges. Without them, Belize would have to rely on expensive and environmentally damaging man-made seawalls. The reefs also play a crucial role in the food web, providing spawning grounds for various species of fish and crustaceans.

To address the issue of coral bleaching, the Belize government has committed to reducing waste dumped into the ocean, preserving natural resources, promoting sustainable tourism practices, and regulating industries along the coastline. While these measures may lead to short-term losses in tourism and exports, they are essential for the long-term survival of the reefs and the well-being of the country.
