India faces a major threat from changes in climate since its economy is closely tied to natural-resource-base and climate-sensitive sectors such as agriculture, water and forestry that happen to be the most vulnerable sectors. India is poorly equipped to cope effectively with the adversities of climate change due to low capabilities, weak institutional mechanisms, and lack of access to adequate resources. Wheat production in the country may decline after 2020 and rice production may be adversely impacted in the eastern states. The eastern region would witness increased temperatures and decreased radiation, resulting in fewer grains and shorter grain filling durations. On the other hand, the potential decline in yields owing to increased temperatures in northern India will be offset by higher radiation, resulting in lower impacts of climate change. There is a possibility of a loss of 4-5 million tonnes in annual wheat production with every 1°C rise in temperature even after considering the carbon fertilisation effect. The climate change will affect various crops during the entire growing period owing to extreme whether events. The adaptability of crops-to-climate variability would acquire significant dimension as frequent occurrence of extreme weather conditions may dictate as to how to cope up with the situation.
