We used the calibrated MYWAS-VALUE model to evaluate the impact of RB versus FB on the optimal inter-regional water allocation policies, the development of water infrastructures, the agricultural activities of the farmers, and the economic welfare of the country. In the analysis, we refer to the role of adaptation by the farmers through the reallocation of their lands to the crops. We first describe the implications on the water supply patterns associated with the switch from FB to RB. Then, we present the allocation of welfare in the economy under the two scenarios and explain the welfare differences between the two scenarios by analyzing the farmers' adaptations through land and water allocations. Finally, we present three alternative measures to determine irrigation water salinity damage.
