Abstract:
Although India’s share in the world’s population is 17.5 % but it has
approximately 4% of the total available fresh water resources (Kumar and
Kumar, 2013). Among these, groundwater resources are depleting at an
alarming rate and in the surface water resources, except a few perennial
rivers most of the rivers are seasonal and rainfed. Climate change can severely
threaten India’s water security and India’s hydro-climatic regime is expected
to alter significantly over the course of the 21st century which will ultimately
affect the food security of India. Various researchers have reported a change
in the climate of India and alteration in the hydrological regimes.
