What is Purpose of artesian basin in the Caribbean?

The purpose of an artesian basin in the Caribbean is to provide a natural reservoir of groundwater that is under pressure and can flow to the surface without the need for pumping. This freshwater resource is vital for drinking water supply, agriculture, and irrigation in the region, where surface water can be limited. Additionally, artesian basins can help maintain the ecological balance by supporting local ecosystems and mitigating the effects of drought. Overall, they play a crucial role in ensuring water security in the Caribbean islands.
