The Impact of Aquatic Salinization on Fish Habitats and Poor Communities in a Changing Climate : Evidence from Southwest Coastal Bangladesh

Fisheries constitute an important source of livelihoods for tens of thousands of poor people in the southwest coastal region of Bangladesh, and they supply a significant portion of protein for millions. Among the various threats fisheries in the southwest coastal region will face because of climate...

The estimates indicate that areas with poor populations that lose species are about six times more prevalent than areas gaining species. 2018-01-10T18:22:50Z 2018-01-10T18:22:50Z 2017-09 Journal Article Ecological Economics 0921-8009 http://hdl.handle.net/10986/29134 CC BY-NC-ND 3.0 IGO http://creativecommons.org/licenses/by-nc-nd/3.0/igo World Bank Elsevier Publications & Research :: Journal Article Publications & Research South Asia Bangladesh
