Command area development by using FAO Cropwat 8.0 model and impact of climate change on crop water requirement-a case study on Araniar reservoir basin (Pichatur dam)
Calculation of irrigation requirements are very important for design the irrigation projects. The irrigation requirements are not adopting scientifically in India. In the present study, the amount of Crop Water Requirement (CWR) for different crops grown in the Araniar Reservoir Basin Command area was calculated by using the FAO CROPWAT model. CROPWAT is a “crop-soil-climate” phenomena will facilitate the estimate of the crop evapotranspiration and irrigation schedule, and agricultural water requirements with different cropping patterns for irrigation planning. Estimation of Reference evapotranspiration and CWR are the very important in application such as irrigation design, irrigation scheduling, water resources management, hydrology and cropping system modelling. The model works on the climatic data as inputs such as minimum and maximum temperature, relative humidity, wind speed, sunshine hours, rainfall, soil parameters and crop details. The CWR was determined in this study for the cropping pattern of the year 2013-14. The results obtained as the CWR requires for the Kharif season as 23.49 MCM (Million Cubic Meter) to irrigate 2226.7 ha and for Rabi Season which is about 8.07 MCM to irrigate 1416 ha in the study area as per 2013 and 2014 cropping pattern system. The past climatic and rainfall data were predicted by using the Artificial Neural Network (ANN) Feed Forward Back Propagation function and IBM-SPSS Statistical model to obtain the future CWR in the study area by making an assumption that there is no change in the cropping pattern system and the future CWR was determined from the years 2015 to 2024.
