Freshwater security

Freshwater security in Te Moanaui Oceania is increasingly threatened by climate change impacts on rainfall patterns, river health, and aquifer recharge. Changing rainfall distribution and more frequent droughts reduce freshwater availability, particularly in island nations reliant on rainfall for water supply. Rising temperatures exacerbate water stress by increasing evaporation rates and intensifying competition for water resources. Saltwater intrusion into aquifers compromises freshwater quality and availability in coastal areas. The following nature-based solutions may be useful to enhance freshwater security.
