A compromise programming based model has been developed for maximizing food
production with minimum allocation of available water at watershed scale after meeting
human, livestock and environmental needs under different scenarios. Agricultural water
allocation in conjunction with available land resources under a set of constraints has been
examined. The formulated model has the potential to analyze the implications of water
availability on agricultural water allocation plans, and consequently food production. A case
study in Indian Himalayan region, where despite abundant availability of water, rainfed
agriculture is mostly practiced by majority of farmers with a primary objective of selfsufficiency
in food production, well demonstrates the applicability of the developed model.
Three distinct scenarios affecting water availability were considered. Analysis of imposition of
fixed mandatory outflows of 20 to 70 % (as per water source) for satisfying environmental
needs with present production mix revealed water scarcity within the study watershed ranging
from 4 to 66 % across various quarters of an year, which necessitates optimum utilization of
rainfed fallow land by allocating it to high value crops ginger and lentil (6 to 32 times more
than existing allocation) on one hand, and drastic reduction (76 to 100 %) of area under all
irrigated crops (except onion with 4–6 times increase) on the other, to achieve the conflicting
objectives. The compromise plans also suggested increase (by 14 % in environmental watershed
scenario) or decrease (by 29 % in degraded watershed scenario) in size of livestock
population as per scenario based water availability. Overall, the compromise plans were
successful in achieving a high percentage (>93 %) of ideal values of the objective functions,
which were 155 to 170 % of existing food production and 71 to 85 % of existing water
utilization across the scenarios. The proposed optimization model has the potential for
application in identical agro-climatic settings to enhance food production in an environmental
friendly manner.
