A component of the NATCOM – national project undertaken by the Ministry of Environment and Forests for making the National Communication to the United Nations Framework Convention on Climate Change (UNFCCC)

The study is an attempt to quantify the impact of the climate change on the water resources of the country. A distributed hydrological model (SWAT) has been used on major river basins using HadRM2 daily weather data.

The study determines the present water availability in space and time without incorporating any man made changes like dams, diversions, etc. The same framework is then used to predict the impact of climate change on the water resources with the assumption that the land use shall not change over time. A total of 40 years of simulation over 12 river basins of the country have been conducted; 20 years belonging to control (present) and the remaining 20 years belong to GHG (future) climate scenario.

Each river basin has been further subdivided into reasonable sized sub-basins so as to account for spatial variability of inputs in the control and GHG scenario. Detailed analyses have been performed over each basin to quantify the possible impacts on account of the climate change.

It has been observed that the impacts of climate change are not consistent over the country and are varying across the river basins as well as sub-basins. The initial analyses have revealed that the GHG scenario may deteriorate the conditions in terms of severity of droughts and intensity of floods in various parts of the country. However, general reduction has been predicted in the quantity of the available runoff in the GHG scenario.

Adaptation strategies to alleviate the possible impacts of climate change have also been touched upon.
