Climate change raises the risk on food security, alters the cropping pattern, and secondly, it also plays the triggering role to widen inequality. The South Asian region is home to nearly half of the poor and malnourished population of the world. In South Asia — Bangladesh, India, Nepal, and Pakistan encounter similar climate induced changes though they differ in their socio-political, economic, and cultural conditions. The physiological population densities (farming population per unit of agricultural land) suggest that these countries belong to the threat zone in terms of climate change impact on agriculture. It has been obvious that any unfavorable climatic conditions mean poor agricultural growth which will have serious ramification on the countries’ economies. Poverty induces poverty; because of the rudimentary technologies used in agriculture, more manpower is needed for farming thus encouraging couples to increase family manpower to invest on farming, which might lead to overpopulation. This paper evaluates how climate change has direct impact on the agricultural development and broader economic growth in the global context and South Asia (Bangladesh, India, Nepal, and Pakistan). Paper unveils the climate change induced challenges in agriculture with the empirical evidence, elaborates the consequences to the farmers livelihood and food security. Based on secondary information, this paper provides climate change risk scenario and recommends few coping strategies to minimize the climate change impact in farming systems and pathway for the future research.
