Climate change is a major concern in the contemporary world, and it poses a growing threat to global agricultural production and food security. Agriculture is intrinsically sensitive to climate variability and change, whether caused by natural or human activity. This paper attempts to understand the impact of climate change on agriculture and crop productivity, with a special focus on Bangladesh. It has been written based on a systematic literature review of previous studies, published reports, climate models, and prediction data. Climate change events—higher temperatures, rise of sea level, changing rainfall patterns, salinity intrusion, land degradation, extreme weather events, and ecosystem disruption—could reduce agricultural output and impede progress toward achieving food security. Finally, the loss of agricultural production due to climate change can have an impact on the entire food supply chain, including food availability, access to resources for acquiring food, food consumption, and food stability. Therefore, there is a need to carry out such investigations to examine the impact of climate change on agricultural productivity and ensure food security for the growing population.
