Due to the effects of climate change, Punjab, which produces 10% of the country's food grains, may witness a decline in yield of between 13% and 1% in its major Kharif and Rabi crops by 2050, according to the synthesis report of the Intergovernmental Panel on Climate Change. On agricultural productivity, the report said that since Punjab was a major agricultural region, changes in precipitation patterns and temperature due to climate change could have significant implications for crop yields. This could affect the livelihoods of farmers and have wider implications for food security. It said that climate change is expected to have a varying impact on agricultural production, especially maize, rice, and cotton yield.
