As every area on the surface of earth is getting populated very rapidly, much water is required in domestic and industrial sectors. Accordingly, the water needs to be diverted from one sectors to the others in future. Due to this in irrigation sector, the water is needed to be diverted so as to have maximum return from the resources available in a river basin. Due to this in an agro-climatic condition, crops should be allocated optimally so that return from the crops are maximum and water consumption is minimum. In view of the above, in the present study, the return from the available crops has been maximized in the river basin while satisfying availability of land, availability of water (both surface as well as ground water), minimum as well as maximum crop area for the projected population of 2050AD. For this purpose, the Ramial Sub-basin of Brahmani Basin in Odisha State has been considered. For optimization of land and water resources of the basin the software LINDO (Language for Interactive Discrete Optimizer) is used. For the purpose of estimation CWR (Crop water requirement) the guidelines of FAO, 1998 has been considered. The model shows that the optimal cropping pattern uses 3186.95 MCM of water and gives a net profit of Rs 183489.2 lakhs. When compared with the existing cropping pattern, it uses 4033.21 MCM of water while giving Rs 114930 lakhs profit. Hence cropping pattern using optimization techniques is suggested to be used in every river basin.
