A multi-objective optimization procedure using the goal programming technique is developed to assist planners so as to sustain the productivity of land at desired level. The decision making model for a planning period of twelve months is formula ted and applied to a canal command area in Orissa in order to demonstrate the economic utilization of irrigation water under controlled conditions. Alternate solutions by changing the goal priorities have been developed and an optimal model has been selected. Out of 12 crop-area allocation models developed by making 16 runs in the computer, the best model is obtained in run 1 when the canal system is operated at its 80 percent design flow with the project efficiency being maintained at 60 percent. By adopting optimal cropping pattern, the cropping intensity has been found to be 256.92 percent and net return per mm of irrigation water as Rs. 14.95which shows a considerable improvement in both economic returns as well as utilization of land and water resources.
