** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** ECOSYSTEM SERVICES MODELING OF AGRICULTURAL LANDSCAPES IS A GROWING FIELD THAT SERVES THE NEEDS OF MULTIPLE STAKEHOLDERS, FROM FARMERS AND LANDOWNERS TO POLICYMAKERS AND ADVOCACY GROUPS. FURTHERMORE, MODELS THAT QUANTIFY THE ECOLOGICAL BENEFITS OF FARMING PRACTICES COULD SUPPORT COMPENSATION SCHEMES THAT PAY FARMERS FOR ECOSYSTEM SERVICES PROVISIONING. HOWEVER, ECOSYSTEM SERVICES MODELING STUDIES ARE INFORMED BY NORMATIVE VALUES THAT REMAIN UNEXAMINED, RAISING ETHICAL QUESTIONS ABOUT WHOSE BIASES DOMINATE THE PUBLIC DISCOURSE ON ENVIRONMENTAL HEALTH.FOR THIS PREDOCTORAL FELLOWSHIP RESEARCH, I PROPOSE TO CONDUCT AN ECOSYSTEM SERVICES ASSESSMENT OF THE IMPACTS OF COVER CROPPING IN THE SUSQUEHANNA RIVER BASIN, A MAJOR SUBREGION OF THE CHESAPEAKE BAY WATERSHED. APPROPRIATE INDICATOR VARIABLES WILL BE SELECTED WITH REFERENCE TO A SYSTEMATIC REVIEW OF THE ECOSYSTEM SERVICES MODELING LITERATURE. IN ADDITION TO EXAMINING THE NORMS AND BIASES IN ECOSYSTEM SERVICES MODELING RESEARCH, THIS PROJECT WILL EVALUATE THE POTENTIAL OF COVER CROPPING AS A MEANS OF MAINTAINING ECOSYSTEM SERVICES UNDER CLIMATE CHANGE.DELIVERABLES FROM THIS PROJECT WILL INCLUDE PEER-REVIEWED JOURNAL ARTICLES AIMED AT ECOSYSTEM SERVICES MODELERS; POLICY BRIEFS TO FACILITATE COMMUNICATION WITH LOCAL POLICYMAKERS; AND MULTIMEDIA CONTENT TO ENGAGE THE BROADER PUBLIC IN ISSUES OF ENVIRONMENTAL MODELING AND MANAGEMENT. THE ULTIMATE GOALS OF THIS PROJECT ARE TO DRAW AWARENESS TO THE PRESENCE OF SUBJECTIVE VALUES AND BELIEFS IN ECOSYSTEM SERVICES MODELING RESEARCH, COMPILE MODELING TECHNIQUES FOR ECOSYSTEM SERVICES ASSESSMENT, AND STRENGTHEN RELATIONSHIPS BETWEEN ECOSYSTEM SERVICES MODELERS, POLICYMAKERS, AND THE PUBLIC. THESE GOALS ARE IN ALIGNMENT WITH AFRI FARM BILL PRIORITY AREA 4, BIOENERGY, NATURAL RESOURCES, AND ENVIRONMENT
