Abstract High temperature and elevated CO2 under future climate change will influence the agricultural productivity worldwide. Burgeoning population along with climate change situation is going to threaten the food security of India. According to IPCC 5th assessment report (2014), global mean surface temperature and concentration of carbon dioxide (CO2) at the end of 21st century will increase by 4.8°C and 539 ppm respectively under Representative Concentration Pathway (RCP) 8.5 scenario. Considering the burning issue present study aims to find out the probable change in different climatic parameters under high greenhouse gas emission (RCP 8.5) scenario during 2021-2095 and their impact on wheat yield and water productivity over six locations (Jalpaiguri, Nadia, Murshidabad, Malda, Birbhum and South 24 Parganas) covering five major agro-climatic zones of West Bengal, a state of eastern India. Results showed that maximum temperature (Tmax) and minimum temperature (Tmin) will increase by 5.3oC and 5.9oC during the end of this century. The increase in annual rainfall will be maximum (22%) at Murshidabad. Wheat yield will increase by 3 to 28% across the study sites. The seasonal crop evapotranspiration value will decline by 1 to 21%. Both water- use efficiency (WUE) and transpiration -use efficiency (TUE) will increase at all the study sites.
