Among the various threats fisheries in the southwest coastal region and Sundarbans mangrove forest will face because of climate change, adverse impacts from increased aquatic salinity caused by sea level rise have been identified as one of the greatest challenges. This paper focuses on 83 fish species consumed by poor households in the region. Using the salinity tolerance range for each species, 27 alternative scenarios of climate change in 2050 were investigated to assess the possible impacts of climate change and sea level rise on aquatic salinity, fish species habitats, and the poor communities that consume the affected fish species. The results provide striking evidence that projected aquatic salinization may have an especially negative impact on poor households in the region. The estimates indicate that areas with poor populations that lose species are about six times more prevalent than areas gaining species.en-USCC BY 3.0 IGOFISH PRODUCTIONFISHFISH HABITATLAND USE ZONINGDETERMINANTSTHRESHOLDSADVERSE IMPACTSADAPTIVE MANAGEMENTFISH RESOURCESFISHERIES PRODUCTIONCOASTAL RIVERSHABITATSFRESHWATER FISHESCRITICAL HABITATSFISH BIOMASSFISHERIES POLICYTROPICAL ECOSYSTEMSSURFACE WATERSUSTAINABLE MANAGEMENTCOMMERCIAL FISHMARTENCOASTAL ZONEMANGROVESBAYAQUATIC RESOURCES MANAGEMENTPELAGIC FISHOPEN ACCESSTIGERBIOMASSSOIL RESOURCEDIETSMARINE SCIENCEABSOLUTE VALUECOMPARATIVE ECOLOGYAQUIFER SYSTEMRIVER NETWORKFISH DIVERSITYCOASTAL ECOSYSTEMSMIGRATIONCONSERVATION OF BIODIVERSITYBIODIVERSITYFRESH WATER FISHSPECIESCONSERVATION PROJECTRAINFALLEXPLOITATION OF RESOURCESFRESH WATER FISHACTION PLANRIVER SYSTEMSBIOLOGICAL SCIENCESPREDATORSFISH YIELDSFISH DIVERSITYGEOGRAPHIC INFORMATIONFRESHWATER FISH SPECIESRESERVESCOASTAL ECOSYSTEMSSHADNATURAL RESOURCESFISH ABUNDANCEDESTRUCTIVE FISHINGFISH HABITATSLAND USECLIMATE VARIABILITYCATFISHSPECIES’ HABITATCOASTAL AREABASINNATIONAL FISHERIESRIVER BASIN MANAGEMENTECOSYSTEMMIGRATION OF FISHFRESH WATERFRESHWATER FISH SPECIESAQUATIC RESOURCESHABITAT LOSSESCOASTAL FISHERIESFISHERIES RESOURCESHABITAT LOSSCLIMATE CHANGEREFUGECOMMERCIAL VALUECARPAQUACULTUREIMPACT OF CLIMATE CHANGECOASTAL COMMUNITIESBIOLOGYFIELD RESEARCHPROTECTIONFORESTSBIODIVERSITY CONSERVATION PROJECTLAKEDRY SEASONFORESTDISTRIBUTION OF FISHCOASTAL LAND USEASSESSMENT REPORTMARINE ECOSYSTEMSHABITATMARINE FISHERIESFOODISSUESPOPULATION ESTIMATESECOLOGICAL IMPACTSSTREAMSFRESH WATERCRABSFISHERIESCATANIMAL PROTEINANCHOVYOCEANSCOASTAL REGIONSECOSYSTEMSFINLANDSCAPEFISHING CAPACITYMARINE FISHCLIMATE CHANGE SCENARIOSHABITAT CHANGEACTION PLANSBREEDINGCONSERVATIONLOCAL FISHERMENFOOD SUPPLYCOASTAL REGIONCREEKSECOLOGYWATER POLLUTIONMARINE RESERVESANIMALTROPICAL FISHERIESNATIONAL FISHERIES POLICYRIVER SYSTEMSLIVELIHOODSHABITAT SIZESMALL FISHZOOLOGICAL SOCIETYSHARKADAPTATION TO CLIMATE CHANGEBIODIVERSITY CONSERVATIONFRESHWATER FISHSEA LEVELLIVING AQUATIC RESOURCESSALINITY DATAWorking PaperWorld Bank10.1596/1813-9450-7593
