A systematic study of climate change impact on fish and fisheries sector in Bangladesh and role of Geospatial science in mitigation

Abstract

Aquaculture is the world’s fastest-growing food-producing sector, with a mean annual growth rate of 5.3% during 2001–2018. Bangladesh, despite being a densely populated and small country, has managed to ensure its high position in this growing economy. Despite widespread benefits, aquaculture in Bangladesh has recently encountered concerns due to climate change, as several climatic threats to fish production have been recognized. It is high time for Bangladesh to try to find an adaptive measure to cope with the adverse effect of climate change, especially in coastal areas. This study will identify the climate change impact on fish in Bangladesh aquaculture and propose how geospatial technology can be utilized to resolve these issues through a systematic literature review from available of past 5 years. The study is expected to benefit the beneficiaries such as aquafarmers, researchers, scientists, and policymakers to resolve the climate-related issues on Bangladesh aquaculture for sustainable production.
