Barbados
Environmental issues

Barbados is susceptible to environmental pressures. As one of the world's most densely populated isles, the government worked during the 1990s to aggressively integrate the growing south coast of the island into the Bridgetown Sewage Treatment Plant to reduce contamination of offshore coral reefs. As of the first decade of the 21st century, a second treatment plant has been proposed along the island's west coast. Being so densely populated, Barbados has made great efforts to protect its underground aquifers.

As a coral-limestone island, Barbados is highly permeable to seepage of surface water into the earth. The government has placed great emphasis on protecting the catchment areas that lead directly into the huge network of underground aquifers and streams. On occasion illegal squatters have breached these areas, and the government has removed squatters to preserve the cleanliness of the underground springs which provide the island's drinking water.

The government has placed a huge emphasis on keeping Barbados clean with the aim of protecting the environment and preserving offshore coral reefs which surround the island. Many initiatives to mitigate human pressures on the coastal regions of Barbados and seas come from the Coastal Zone Management Unit (CZMU). Barbados has nearly 90 kilometres (56 miles) of coral reefs just offshore and two protected marine parks have been established off the west coast. Overfishing is another threat which faces Barbados.

Although on the opposite side of the Atlantic, and some 4,800 kilometres (3,000 miles) west of Africa, Barbados is one of many places in the American continent that experience heightened levels of mineral dust from the Sahara Desert. Some particularly intense dust episodes have been blamed partly for the impacts on the health of coral reefs surrounding Barbados or asthmatic episodes, but evidence has not wholly supported the former claim.

Access to biocapacity in Barbados is much lower than world average. In 2016, Barbados had 0.17 global hectares of biocapacity per person within its territory, much less than the world average of 1.6 global hectares per person. In 2016 Barbados used 0.84 global hectares of biocapacity per person - their ecological footprint of consumption. This means they use approximately five times as much biocapacity as Barbados contains. As a result, Barbados is running a biocapacity deficit.
