Most of the potable water requirement of Tuvalu is fulfilled by the storage system of the catchments which are getting dried. There is continuous erosion of beaches due to the carrying away of sand from beaches to use it in construction works and also there is excessive deforestation.  

All these devastating factors are causing a climate change in Tuvalu.
