Today agriculture is the single most and the largest sector of Bangladesh’s economy which accounts for 12.64 percent of the Gross Domestic Product (GDP) and 47.30 percent of the labor force. It may consider as the lifeline of Bangladesh economy. It has to be noted that climate change have an effect on agriculture in various ways including through changes in average temperatures, rainfall patterns, atmospheric carbon dioxide (CO2) and ground-level ozone concentrations (O3), nutritional quality of some foods, and sea level rise etc. The paper will focus on the major challenges of climate change on agricultural development and food security issues in Bangladesh. Climate change has possibility of negative impact on crop production as well as all other sectors of agriculture. In effect, these changes may increase the risk of food security in our country. Field study clarified about the negative effects on food production, wherever most of the farmers observed unfavorable change in weather patterns especially in case of precipitation and temperature. Therefore it is very much urgent to determine the potential mitigation measures to cope with the problem associate with the climate change by further investigation. Government and nongovernment organizations might come forward to find out the optimum solutions; besides, national and international joint cooperation is highly required for not only saving our own country but also the human civilization.
