Water is becoming precious and scarce, with the increasing demand for it, due to growth of population and rapid industrialization. The objective of this study was, to determine the impact of potential climate change on crop water requirement (CWR), of crops growing in Adilabad, Prakasam and Ananthapur districts, for present and future decades using CROPWAT model under RCP 4.5 and RCP 8.5 Scenarios. From this, weather data have been generated from General Circulation Model (GCM) i.e., MarkSim website. Then that data are given as input, along with the crop data and soil data to the CROPWAT software, which gives the output as ETc, effective rainfall and irrigation requirement for both RCP 4.5 and RCP 8.5 scenarios.
