Economic Assessment of Water Resources Management Strategies

AbstractThis paper presents an economic framework of all potential benefits and costs arising from present activities and implementation of policies; including crop production costs, capital and operating costs of development projects, environmental costs, pumping costs, and costs imposed by reduced crop production. The methodology was applied for a water resource system of Rafsanjan Plain, in the central part of Iran. The water supply and demand system of the region was simulated into two different models. The former was a decision support system (DSS)-based model, and the latter was a system dynamics-based model. Despite some minor differences, the principal characteristics of the region was similarly simulated in both models. Then, management scenarios were generated considering different strategies including the interbasin water transfer, improvements in irrigation techniques, limiting future expansion of cultivated area, and restricting withdrawal from groundwater. By combining these strategies, vari...
