Antigua & Barbuda: Environmental Challenges

As a small island developing state, Antigua and Barbuda faces environmental pressures that are disproportionate to its size. Rising sea levels, estimated by regional monitoring at roughly 1.5 to 2.0 millimeters per year across the Caribbean, are accelerating coastal erosion along beaches that anchor the tourism industry. Combined with storm surge and, in places, unsustainable coastal development, this erosion threatens infrastructure and property in low-lying areas of both islands.

Marine ecosystems are under similar strain. Coral reefs are degrading due to ocean warming, pollution, and overfishing, while mangroves and seagrass beds, which buffer the coastline and support fish stocks, face habitat loss in some areas. Freshwater scarcity is a persistent concern as well, since the islands depend largely on rainfall and desalination rather than rivers or lakes, leaving water supply vulnerable to drought.

Hurricanes remain the most immediate hazard: the Atlantic hurricane belt passes directly through the region each year from June to November, and scientific assessments suggest storms are growing more intense. Barbuda's near-total evacuation after Hurricane Irma in 2017 illustrated the scale of disruption a single storm can cause. In response, the government has pursued climate adaptation planning and works with regional and international partners on resilience and disaster preparedness initiatives.
