** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** THIS SUBMITTED PROPOSAL FOCUSES ON ENVIRONMENTAL AND NATURAL RESOURCE ECONOMICS (ENRE) . THE LONG-TERM GOAL OF OUR RESEARCH IS TO SUPPORT EVIDENCE-BASED POLICYMAKING BY DESIGNING POLICY INCENTIVES THAT ENCOURAGE FARMERS TO CONSERVE AGRICULTURAL IRRIGATION WATER IN THE CONTEXTS OF UNCERTAIN WATER SUPPLIES AND COMPLEX INSTITUTIONAL WATER ARRANGEMENTS. THIS PROJECT AIMS TO UNDERSTAND THE MECHANISMS UNDERLYING FARMERS' WATER-RELATED AGRICULTURAL DECISIONS AND DEVELOP FEASIBLE POLICY OPTIONS TO INFORM THE DEVELOPMENT OF SUSTAINABLE AND RESILIENT AGRICULTURE UNDER PRESENT AND FUTURE CLIMATES. TO ACHIEVE THIS GOAL, WE PROPOSE FOUR OBJECTIVES: 1) COLLECT IRRIGATION WATER RIGHTS AND RUNOFF DATA AND COMPILE A PARCEL-LEVEL GEOSPATIAL DATABASE COVERING THREE UTAH WATERSHEDS, 2) EXPLORE THE IMPACT OF APPROPRIATE WATER RIGHTS AND WATER SUPPLY UNCERTAINTY ON FARMERS' AGRICULTURAL MANAGEMENT PRACTICES, 3) ESTIMATE INDIVIDUAL FARMERS' WILLINGNESS-TO-ACCEPT PAYMENTS IN EXCHANGE FOR IRRIGATION WATER-SAVING, AND 4) DESIGN INCENTIVE-BASED AGRICULTURAL WATER-SAVING POLICIES AND ESTIMATE THE MARGINAL COSTS OF AGRICULTURAL WATER CONSERVATION UNDER DIFFERENT POLICY OPTIONS AND CLIMATE CHANGE SCENARIOS.OUR INTERDISCIPLINARY TEAM WILL BRING TOGETHER EXPERTISE IN ECONOMIC MODELING OF WATER RESOURCES MANAGEMENT AND AGRICULTURAL LAND MANAGEMENT AND HYDROCLIMATE MODELING AND CLIMATE CHANGE SCIENCE TO DEVELOP NEW MODELS AND TOOLS TO UNDERSTAND ECONOMIC AND WATER CONSERVATION IMPACTS OF CERTAIN POLICY CHOICES. BY CAREFULLY EXAMINING THE IMPLICATIONS OF FARM MANAGEMENT PRACTICES AND THEIR RELATIONSHIP TO WATER CONSERVATION, OUR PROJECT WILL CONTRIBUTE TO UNDERSTANDING THE ECONOMIC TRADEOFFS OF WATER CONSERVATION IN AGRICULTURE. ULTIMATELY, OUR WORK WILL INFORM THE DESIGN OF INCENTIVES, ESTIMATED COSTS OF AGRICULTURAL WATER CONSERVATION, AND REAL-WORLD IMPLEMENTION.
