These shifts are projected to have significant implications for nature-based livelihods, resource availability, market prices, and the food and nutrition security of coastal populations, particularly those with limited choices and affordability. The vulnerabilities arising from these changes underscore the critical need for adaptaton planning to build resilience.  In the southwest coastal region of Bangladesh, rising sea levels and upstream changes in freshwater flux are intensifying riverine salinity, with annual flux dynamics driving substantial salinity changes and providig insights into future trends as high-salinity water encroaches further inland. In this study, river salinity monitor data were combined with fish sales records from nearby wholesale markets to evaluate the magnitude, spatial distribution, and fishig impact of salinity changes throughout 2023. Significant impacts on fish quantities were observed, and analysis of associated child health data revealed that salinity-related health challenges persist despite steady poverty reduction. Econometric aalysis of fish catch records demonstrated that salinity changes differentially affect the availability of fish species with varying salinity tolerances, reflecting the interplay of species-specific salinity aversion and fishers\u2019 adaptive strategies o optimize profitable catches. These findings highlight the importance of complementing technical assessments of species-specific salinity tolerances with empirical salinity and catch data to improve projections of salinity impacts on fish consumptin in affected regions. The results provide actionable insights into the dynamic interactions between environmental change, ecological responses, and human adaptation in coastal settings.","geographic_units":[{"name":"Bangladesh","code":"BGD"}],"keywords":[{"name":"Climate Change"},{"name":"River Salinity"},{"name":"Fishing"},{"name":"Child Health"},{"name":"Bangladesh"}],"topics":[{"id":"Q21","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Demand and Supply \u2022 Prices","parent_id":"Q2"},{"id":" Q22","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Fishery \u2022 Aquaculture","parent_id":"Q2"},{"id":" Q25","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Water","parent_id":"Q2"},{"id":" Q54","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Climate \u2022 Natural Disasters and Their Management \u2022 Global Warming","parent_id":"Q5"},{"id":" I14","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Health and Inequality","parent_id":"I1"}],"output":[{"type":"Working Paper","description":"Policy Research Working Papers (PRWP)","title":"Fishing And Climate Change In Coastal Bangladesh: The Economic And Health Impacts Of Increasing Salinity","doi":"https:\/\/doi.org\/10.1596\/1813-9450-11048","uri":"http:\/\/documents.worldbank.org\/curated\/en\/099015001272526956"}],"language":[{"name":"English","code":"EN"}],"disclaimer":"The materials in the reproducibility packages are distributed as they were prepared by the staff of the International Bank for Reconstruction and Development\/The World Bank.
