Freshwater systems on small islands are exposed to dynamic climate impacts and are among the most threatened on the planet. An 11-36% reduction is estimated in the volume of fresh groundwater lens of the small atoll islands  of the Maldives due to SLR. The El Niño-related 2015-2016 drought in Vanuatu led to reliance on small amounts of contaminated water left at the bottom of household tanks. A Caribbean high-resolution drought atlas spanning 1950-2016 indicates that the region-wide 2013-2016 drought was the most severe event during the multi- decadal period. In Puerto Rico, the island experienced 80 consecutive weeks of moderate drought, 48 weeks of severe drought and 33 weeks of extreme drought conditions between 2014 and 2016. Increasing trends in drought are apparent in the Caribbean although trends in the western Pacific are not statistically significant .
