Three irrigated agricultural field demonstration sites have been established to evaluate approaches to water conservation such as alternative crop rotation, irrigation scheduling, timing, and management, and crop residue management.   Detailed water budgets will be assessed to document the potential water savings from a range in cropping approaches.  Economic evaluations will include both farm scale profitability analysis as well as projecting economic impacts at community, region, and basin scales for different scenarios of climate and water allocation.  The project includes an aggressive plan to provide information on limited irrigation technologies to agricultural audiences and to provide information about how changes in agriculture water allocations may affect local and regional economies.
