Small island states are the most vulnerable to the impacts of climate change, despite not contributing much to global greenhouse gas emissions. Crafting effective science-based adaptive strategies to conserve and sustain natural resources in the face of the changing climate has important socio-economic, political, and ecological dimensions. The analysis in the current paper reveals that the island of Mauritius has been warming at a rate of 0.0216 degrees C/year over the period 1971-2020, with an increase in precipitation averaging 2.29 mm/year over the 1981-2020 period. The changing climate over time has had severe repercussions on the native ecosystems of the island and is threatening the long-term freshwater supply system. Science-based policy measures proposed revolve around the expansion and re-design of protected areas to be strategically located in climate-resilient regions that seek to offer refuge to native fauna and flora. To increase the resilience on freshwater supply on the island, measures proposed include the introduction of a freshwater coordination-based system that operates on water stress level, in addition to increasing the network of freshwater catchment areas in regions where precipitation is increasing over time. The insights in this paper are expected to be valuable for other small islands in adapting to climate change.
