IMPACTS OF CLIMATE CHANGE ON THE AGRICULTURAL SECTOR

Anitta Malar Jose

Abstract


Agriculture represents a core part of the Indian economy and provides food and livelihood activities to much of the Indian population. While the magnitude of impact varies greatly by region, climate change is expected to impact on agricultural productivity and shifting crop patterns. The policy implications are wide-reaching, as changes in agriculture could affect food security, trade policy, livelihood activities and water conservation issues, impacting large portions of the population.  The agricultural sector represents 35% of India’s Gross National Product (GNP) and as such plays a crucial role in the country’s development. Food grain production quadrupled during the post-independence era; this growth is projected to continue. The impact of climate change on agriculture could result in problems with food security and may threaten the livelihood activities upon which much of the population depends. Climate change can affect crop yields (both positively and negatively), as well as the types of crops that can be grown in certain areas, by impacting agricultural inputs such as water for irrigation, amounts of solar radiation that affect plant growth, as well as the prevalence of pests. The Indian Agricultural Research Institute (IARI) examined the vulnerability of agricultural production to climate change, with the objective of determining differences in climate change impacts on agriculture by region and by crop. The Indian Agricultural Research Institute (IARI), New Delhi is a research organization under the Indian Council for Agricultural Research (ICAR). It conducts various professional courses in agricultural sciences and allied fields. The research area of the institute covers the entire range of agricultural science.
