It develops linked models to capture connections between resource stocks and flows and the resulting microeconomic and macroeconomic impacts. A bioeconomic model is developed that is imbedded into a computable general equilibrium (CGE) model. Incorporating imperfect regulation, the bioeconomic model characterizes optimal policies, while the CGE model explores the economy-wide consequences of possible changes to the ecosystem. The model is parameterized and calibrated to the case of the Serengeti ecosystem which is perhaps the most intensively researched biome with a relative abundance of data. This ecosystem is also undergoing rapid change from a host of factors related to developments within and around the protected area system. The analysis identifies the contribution of the ecosystem to the economy and finds that changes in tourism and bushmeat hunting have surprisingly diffuse economy-wide impacts, that are especially large in the rural sector. To guard against overstatement, ecosystem impacts are under-stated relative to other effects. The results suggest that linkages to the natural resource sector (backward and forward multipliers) are important and neglecting these may lead to biased estimates.en-USCC BY 3.0 IGOAGRICULTURAL EXPANSIONAGRICULTURAL FRONTIERAGRICULTURAL LANDAGRICULTURAL PRODUCTIONAGRICULTUREALTERNATIVE USESAMOUNT OF LANDANIMALANIMAL ECOLOGYANIMAL POPULATIONANIMALSARTISANAL MININGAVERAGE COSTSBEACHBEACHESBENCHMARKBIODIVERSITYBIOECONOMIC ANALYSISBIOECONOMIC MODELBIOECONOMIC MODELSBIOMASSBUFFER ZONESCARRYING CAPACITYCLIMATE CHANGECOMMUNITY INCENTIVESCONSERVATIONCONSERVATION AREACONSERVATION BIOLOGYCONSERVATION POLICYCONSERVATION SCIENCECROP DAMAGECROP PRODUCTIONCULTIVATED LANDDECISION MAKINGDETERMINANTSDEVELOPMENT ECONOMICSDEVELOPMENT POLICYDEVELOPMENT PROJECTSDOMESTIC CATTLEDOMESTIC TOURISMDOMINANT SPECIESECOLOGICAL APPLICATIONSECOLOGICAL ECONOMICSECOLOGICAL FUNCTIONSECONOMIC IMPLICATIONSECONOMIC SECTORSECONOMIC SIGNIFICANCEECOSYSTEMECOSYSTEM DYNAMICSECOSYSTEMSELEPHANTSEMPIRICAL STUDIESENCROACHMENTENVIRONMENTAL CHANGEEQUILIBRIUMEVOLUTIONEXPECTED UTILITYFISHFOOD CHAINFORAGEFORESTFOREST HABITATFUNCTIONAL FORMSFUTURE RESEARCHGAZELLESGDPGRASSLANDSGROWTH RATEHABITATHABITAT FRAGMENTATIONHABITAT LOSSHARVEST RATESHARVESTERSHIGH DENSITYHUMAN IMPACTSHUNTERSHUNTINGILLEGAL HUNTINGIMPACT OF TOURISMINDIRECT UTILITYINDIRECT UTILITY FUNCTIONINTERNATIONAL TOURISTSISSUESKEYSTONE SPECIESLAND ALLOCATIONLAND COVERLAND USELAND-USELANDSCAPELIVESTOCKMIGRATIONMULTIPLIERSNATIONAL ECONOMYNATIONAL PARKNATIONAL PARKSNATURAL CAPITALNATURAL RESOURCENATURAL RESOURCE CONSERVATIONNATURAL RESOURCESNATURENEGATIVE CONSEQUENCESOPEN ACCESSOPTIMIZATIONPARTIAL EQUILIBRIUM ANALYSISPASTURESPOACHINGPOPULATION DECLINEPOPULATION DENSITIESPREDATORPREDATOR POPULATIONSPREDATOR-PREY DYNAMICSPREYPRICE ELASTICITYPROPERTY RIGHTSPROTECTED AREASQUOTASRAINFALLRAINFALL VARIABILITYREGENERATIVE CAPACITYRHINOSSAFARISAVANNASIMULATIONSPECIESSPECIES INTERACTIONSSPORT HUNTINGSUSTAINABLE DEVELOPMENTTOURISMTREEUNDERESTIMATESUSE VALUEVALUE ADDEDWAGESWILDLANDSWILDLIFEWILDLIFE CONSERVATIONWILDLIFE MANAGEMENTWILLINGNESS TO PAYZEBRAS10.1596/1813-9450-6890
