Rice-Wheat cropping system under changing climate Scenario: A review

Abstract

Climate change directly or indirectly influences all economics aspects, but agriculture is among the sectors which are most sensitive and inherently vulnerable to climate. The impacts of increased temperature from global warming and changes in rainfall patterns resulting from climate change are expected to reduce agricultural production and put further pressure on marginal land. Climate change and especially increase in ambient temperatures will reduce the yields of major cereal crops especially Rice-wheat. Hence, to achieve our goals of food security, we need to emphasize the use and production of food crops that can withstand the on-going changes to the climate, especially in the arid and semi-arid regions around the globe that are at a greater risk of food insecurity. There are key factors that significantly impact to mitigate stress conditions of the climate, i.e. short duration crop, value added weather services, genotype with higher per day yield potential, weather linked agricultural insurance etc.
