**AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** AGRICULTURAL SOILS PROVIDE BOTH PRIVATE BENEFITS AND ECOSYSTEM SERVICES TO THE PUBLIC. SOIL ORGANIC CARBON (SOC) INCREASES PRODUCTIVITY FOR PRODUCERS AND CONTRIBUTES TO LONG-TERM FOOD SECURITY, WHILE BUILDING SOC STOCKS ALSO REDUCES THE AMOUNT OF GHGS IN THE ATMOSPHERE. FURTHER, CLIMATE CHANGE WILL HARM AGRICULTURAL PRODUCERS, SO GHG ABATEMENT CAN INCREASE LONG-TERM PRODUCTIVITY.THIS PROJECT WILL STUDY THE POTENTIAL FOR AGRICULTURAL PRODUCERS IN THE US CORN BELT TO INCREASE SOC AND REDUCEEMISSIONS THROUGH INCENTIVE-BASED PROGRAMS BY CREATING A GHG ABATEMENT SUPPLY CURVE THAT ACCOUNTS FOR PRIVATE BENEFITS OF SOC. WE WILL MAKE TWO KEY CONTRIBUTIONS. FIRST, WE WILL USE PARCEL-LEVEL DATA TO MODEL HETEROGENEITY IN CROP AND PRACTICE CHOICES USING OBSERVED BEHAVIOR. SECOND, WE WILL INTEGRATE ECONOMIC AND BIOGEOCHEMICAL MODELS TO EXAMINE HOW THE SUPPLY CURVE MAY CHANGE OVER TIME. THE GHG ABATEMENT SUPPLY CURVE WILL BE USED TO CHARACTERIZE THE SCOPE OF CARBON MITIGATION INITIATIVES THAT ALLOW PRODUCERS TO RECEIVE PAYMENTS FOR REDUCING EMISSIONS.THE PROPOSED RESEARCH RELATES TO TWO TOPICS IN THE ENVIRONMENTAL AND NATURAL RESOURCE ECONOMICS AREA. OUR INTEGRATED MODELING APPROACH WILL EXAMINE THE RELATIONSHIP BETWEEN AGRICULTURE, NATURAL RESOURCE CONSERVATION, AND THE ENVIRONMENT IN ORDER TO STUDY THEECONOMICS OF CONSERVATION AND ENVIRONMENTAL POLICIES. WE WILL ALSO EXAMINE THE DESIGN OF INCENTIVE MECHANISMS AND POLICIES THAT PROMOTE SUSTAINABILITY, WITH A PARTICULAR FOCUS ON CARBON OFFSET PROGRAMS. OUR RESEARCH WILL INVESTIGATE THE ROLE OF FINANCIAL PAYMENTS FOR INCENTIVIZING SOIL AND LAND CONSERVATION BY AGRICULTURAL COMMODITY PRODUCERS THAT INCREASE SOC AND REDUCE EMISSIONS.
