Impact of climate change on agriculture: an investigation of vulnerability and adaptation of the coastal areas of Bangladesh

Bangladesh is one of the worst affected countries that are facing the early impacts of climate change particularly in agricultural sector .. The coastal area of Bangladesh is naturally susceptible to natural disaster whereas climate change asserts a new depressing effect on the lives and agronomy of the coastal area. The aim of this work is to assess the impact of climate changes on agriculture in the coastal area of Bangladesh. The study was based on long-term climatic and crop productivity data, regional.climatic scenarios and impact analysis of different aspects of climate change on agriculture. The study reveals that the crops yield would be negatively impacted by rise in temperature, erratic rainfall, flooding, droughts, salinity, etc. and among which water logging and drainage congestion are the major problems. The ecological conditions are more vulnerable which is very likely to be alerted though slowly but surely due to climate change and sea level rise. Dependency on fertilizer and irrigation . is increasing which leads to permanent fertility loss of the land, loss of biodiversity, extinction of local verities, ground water scarcity, loss the sustainability of production. However, adaptations to climate change like agronomic manipulations, sustainable climate-resilient agriculture, shifting the planting dates, using short duration crop cultivars can reduce vulnerabilities, delay the process and increase food security.
