Impact of climate change on food security in southwest coastal region of bangladesh

This paper examines the impact of climate change on food security of the population residing in the coastal area of Bangladesh. Based on multistage random sampling technique, a survey was conducted to collect socioeconomic and food datasets of the people affected by extreme climate events in the country. The study found that climate change caused food insecurity in the region; it led to greater dependence on pond and rain water for cooking food and water intake. Catastrophe due to extreme weather events adversely affected the livelihoods and level of income. The severe cyclonic storms, Sidr (November 2007) and Alia (May 2009) severely affected the vulnerable people of this region, especially the extremely poor. The study came out with several coping strategies to address adverse effects of climate change, including rehabilitation with income and employment generating activities and development training; alternative livelihood adaptation practices; access to subsidized inputs and credits; introduction of crop calendar; conservation of arable and fellow land; and innovation of saline-tolerant, heat-resistant, moderate water consuming and short-rotation crops for the coastal people.
