Water is a renewable resource, but current use does affect future availability, particularly in the case of groundwater. Moreover, variations in year-to-year availability (of rainfall and surface water) are high and therefore our capacity to buffer against drought years also needs to be considered. Thus, both sustainability of average use under average conditions, and resilience against major droughts are of concern.⁸
In the Arkavathy sub-basin, there is evidence that both physical and socially acceptable limits to water extraction are being exceeded in several ways, thereby affecting future sustainability and resilience.
1) Current surface water sources are drying up.
