Scenario of climate changes in the context of agriculture

Abstract

The abrupt increases in temperature as well as increasing population density are two major factors, which are threatening the world's food security. A holistic approach is needed to address this situation to overcome the risk of food paucity. Therefore the agricultural scientists worldwide need to develop the coordinated research efforts covering all disciplines that encroach on agricultural productivity to minimize the unpleasant effects of climatic changes within the available natural resources. For this, a stress-tolerant germplasm coupled with natural resource management as well as policy interventions should be devised to ensure crop productivity under unpredictable environmental conditions. The countries that are located in temperate zones may extract some benefit from this change in temperature whereas the countries located in the tropical and subtropical regions have an increased vulnerability towards the effects of rising temperature.
