Abstract/ Executive Summary:

Climate change has heterogeneous effect on crop production. Potential yield of some crops were found to be decreasing in different simulation models. High temperature, drought, salinity, excessive rain fall are the major stresses faced by crops in a changing climatic condition. Coastal areas of Bangladesh are highly vulnerable to climate change. It was found that a total of 1,405.57 MT yield are lost in different crops. Data shows the production trends of many crops remaining in a steady state or their increase is very slow compared to elapse of time. Some possible adaptation measures such as sorjan system, floating bed agriculture, growing crops in raised beds, harvesting rain water, cultivation of salt and flood tolerant crop varieties etc. were suggested to reduce possible climate change risk and to cope up with the current situation.

Program Area: Risk Management in Agriculture

Non-commodity: Weather/Climate

Objectives:

To reduce possible climate change risk and to cope up with the current situation.

Methodology:

Scientific approach requires a close understanding of the subject matter. This paper mainly depends on the secondary data. Different published reports of different journals and reports mainly supported in providing data in this paper. This paper is completely a review paper. Therefore no specific method has been followed in preparing this paper. It has been prepared by Internet search, comprehensive studies of various articles published in different journals, books and proceedings available in the libraries of BSMRAU, BARI, BRRI and BARC. Valuable information has been collected through personal contact with respective resource personnel to enrich the paper. It compiled the all related information to prepare this paper.

Achievement/Findings:

Climate change can boost up certain crop’s production and also can decrease particulars yield. Therefore it is advised to cultivate stress tolerant crops and change production technology in vulnerable areas such as coastal region and flood prone areas. Bangladesh is not responsible for climate change or global warming, but is severely affected. To cope with the present situation of climate change in crop sector of Bangladesh, research should be conducted for introducing of salinity and flood tolerant variety of crops. Otherwise, the food security will be hampered in the near future.
