| Abstract | Climate variability has been the primary source of fluctuations in the global food production since the past till now and the countries of developing world are more affected by it. Decline in precipitation and increase in temperature causes severe stress on the water resources. Water footprint was provided to assess the water resources utilization in the agricultural production process under climate change. The study is done to compute the water footprint of the major crops in the Indrawati basin for the years 1980 - 2009 and the impacts of climate change on water footprint. The water footprint of the future climate scenarios under one GCM and one RCM namely, HaD GEM - 3RA and MIROC ESM respectively was calculated. The results indicate that wheat and barley are the most water efficient crops in the basin. The water footprint for the past 30 years’ period shows decreasing trend. Though the precipitation is decreasing and temperature is increasing, the yield for the crops is increasing throughout the period thus this contribute to decrease in the water footprint. The average water footprint for paddy, wheat, maize, millet and barley were respectively, 2817 m 3 /ton, 1870 m 3 /ton, 2289 m 3 /ton, 2716 m 3 /ton and 2337 m 3 /ton. During the green water footprint calculation, precipitation and maximum temperature has more significant effect in wheat among all the crops and during blue water footprint calculation, precipitation has more significant effect on wheat among all crops. The green and blue water footprint for the future scenarios are projected to be decreasing |
