Interrelationship Between Surface and Groundwater: The Case of West Bengal
The interrelationship between surface and groundwater in West Bengal has not been properly studied. Even the water management planning often suffers from inadequate knowledge at official level. This paper gives an estimate of water resource of West Bengal. The groundwater in West Bengal has been depleting fast. It has been observed that groundwater is depleting at 25.5 cm/year in 296 blocks. This is due to over-exploitation of groundwater to ensure irrigation in bodo(dry variety paddy) season. The situation is further aggravated due to climate change. The farmers are often troubled due to delayed onset of monsoon and decline in monsoon rainfall. We need to formulate a policy to cope with the changing scenario.
