The Caribbean and Pacific regions have historically been affected by severe droughts  with significant physical impacts and negative socioeconomic outcomes. Water quality is affected by drought as well as water availability. The El Niño related 2015-1016 drought in Vanuatu led to reliance on small amounts of contaminated water left at the bottom of household tanks . The highest land disturbance percentages have coincided with major droughts in Cuba . Drought has been shown to have an impact on rainwater harvesting in the Pacific  and Caribbean , especially in rural areas where connections to centralised public water supply have been difficult. Increasing trends in drought are apparent in the Caribbean  although trends in the western Pacific are not statistically significant .
