The concentration of greenhouse gases has increased as a result of anthropogenic activities, which resulted in the warming of the earth atmosphere. The agriculture sector contributes to emission of greenhouse gases and is also worst affected from the global warming. The increasing concentration of carbon dioxide may have fertilization effect on the productivity of rice-wheat system, but this effect will be negated by the simultaneous increase of temperature. The rise in the day-time maximum temperature has positive effect on the rice yield but negatively affected the wheat yield. While rise in the night-time minimum temperature decreased the yield of rice. Our goal here is to discuss the possible effects of shift in the climatic variables on the productivity of rice-wheat system that will provide important insights for adapting to it.Various options to mitigate the negative impacts of climatic shift on the productivity of rice-wheat system have been discussed.
