Small Islands Developing States (SIDS) are at the forefront of climate change and its consequences, particularly with regard to their freshwater resources. 71% of SIDS face a risk of water shortage, a figure that goes up to 91% in SIDS with the lowest altitude.
Surrounded by the ocean, their groundwater is prone to saline intrusion: 73% of SIDS face a risk of groundwater pollution. It is a major challenge for countries that are vulnerable to phenomena such as tsunamis, hurricanes, floods or drought. A trans-sectoral and interdisciplinary approach is necessary to ensure water security in SIDS
