Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. For the first time, a new study maps this loss of groundwater storage capacity around the world.
The continuance of groundwater in Central Valley threatens even underground water reserves. Drought is the prolonged period of abnormal heat in a certain area or region, which can last indefinitely.
