Despite the rains, the Caribbean region suffers frequent water stress conditions

The region has suffered a trend of increasing drought since 1960. This trend is putting Central American food security at risk by affecting basic crops.

Despite being in the tropics and having defined rainy seasons from approximately April to May, the Caribbean region (Mesoamerica and the Antilles Islands) is a space where conditions for severe water stress exist for three main reasons:

The scenic beauty of Barbuda Island has reverted to an excessive urban development that endangers both the balance of the island’s natural environment and its biological species. In addition to the drought, the island is frequently hit by hurricanes, and was severely affected by Hurricane María in 2017. Source: Sean Pavone.

7 out of the 36 countries with the greatest water stress on the planet are in the region, highly associated with island-states and their lack of rivers or aquifers of much importance. The island-states of Barbados, Antigua & Barbuda and St. Kitts & Nevis are three of the most vulnerable, with less than 1.000 m3 per capita. Many island-states depend exclusively on the rainwater for human consumption and agriculture.

The region has suffered a trend of increasing drought since 1960, mainly affecting sections of the Central American Dry Corridor (CADC), and the dry ecosystems in Guatemala, Honduras, Nicaragua and El Salvador. This tendency is putting the Central American food security at risk and is affecting essential crops such as corn, that are completely dependent on rainwater.

Droughts, hurricanes and human migrations

In addition to the impacts caused by drought (prolonged or specific years of El Niño or AMO/NAO), many regions of the Caribbean are simultaneously affected by hurricanes and floods that are entailed. This multitude of overlapped extreme events exceeds the response capacity of many Governments of the region and provokes mass exodus of persons looking for opportunity in the future. Mass Migrations from the Central American Dry Corridor took place after the drought of el Niño phenomenon in the years 2015-2016 and 2018-2019, followed by the mega-hurricane seasons of 2017 and 2020.
