** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** CONTINUATION OF THE CURRENTLY USED PRACTICES TOWARD FUNCTIONING OF THE LIVESTOCK SYSTEMS IN THE U.S. POSES A MAJOR CHALLENGE FOR THE ACHIEVEMENT OF SUSTAINABLE DEVELOPMENT GOALS AND CLIMATE MITIGATION TARGETS. A SET OF POLICY SOLUTIONS IS REQUIRED TO TRANSFORM THE SECTOR IN A SUSTAINABLE MANNER, PRESERVING THE IMPORTANT SOCIAL AND ECONOMIC ROLES THAT LIVESTOCK SYSTEMS PLAY. A KEY CONTRIBUTION OF THE STUDY WOULD BE AN IDENTIFICATION OF THE MOST EFFICIENT FORWARD-LOOKING POLICY OPTIONS TOWARD SUSTAINABLE TRANSITION IN THE LIVESTOCK SECTOR IN THE U.S., TAKING INTO ACCOUNT IMPACTS AND INTERACTIONS WITH FOOD SYSTEMS IN THE REST OF THE WORLD. AN IMPORTANT FEATURE OF THE ANALYSIS WOULD BE A CONSIDERATION OF THE CONTEXT OF EXTERNAL (TO THE LIVESTOCK SECTOR) DRIVERS THAT ARE SHAPING THE FUTURE OF THE SECTOR, SUCH AS CHANGES IN TECHNOLOGIES AND EMERGENCE OF NEW PRODUCTS (E.G., MEAT SUBSTITUTES), CLIMATE IMPACTS, INTERACTIONS OF FOOD SYSTEMS WITH OTHER PARTS OF THE ECONOMY AND CHANGING SOCIO-ECONOMIC CONDITIONS. BY CONSIDERING ALTERNATIVE POLICY SOLUTIONS (POLICIES TOWARD LIVESTOCK CIRCULARITY, EMISSION REGULATIONS, MEAT TAXES, ETC.) THE STUDY WOULD SUPPORT THE DECISION-MAKING PROCESS IN THE PART OF DESIGN AND IMPLEMENTATION OF POLICIES INTENDED TO AFFECT AGRICULTURAL PRODUCTION AND TECHNOLOGY ADOPTION. IMPLICATIONS OF THE CONSIDERED POLICY SOLUTIONS WOULD PROVIDE A QUANTIFICATION OF ALTERNATIVE SCENARIOS FOR THE AGRICULTURAL PRODUCTION AND RESOURCE USE, SUPPORTING THE OTHER IMPORTANT PROGRAM AREA PRIORITY. BY CAPTURING INTERACTIONS BETWEEN U.S. LIVESTOCK-RELATED SUSTAINABILITY POLICIES AND THE GLOBAL FOOD AND SOCIO-ECONOMIC SYSTEMS, THE PROJECT WOULD CONTRIBUTE TO THE POINT OF COMPETITIVENESS IN INTERNATIONAL TRADE AND DOMESTIC MARKETS.
