Impact of Climate Change on the Productivity of Rice and Wheat Crops in Punjab

The seasonal trends in climate variables and their impact on rice and wheat yields in Punjab are assessed using daily data of temperature and rainfall by district from 1986 to 2015. A significant rise in mean temperature is observed in both the rice- and wheat-growing periods. Rainfall during the rice-growing period has decreased 7% annually over the past 30 years. Significant climate change will lower the rice yield by 8.10% by 2080 and wheat by 6.51%. To mitigate the effects of climate change, it is necessary to adopt climate-resilient crop choices and irrigation practices and technologies.

Cropping Pattern in Punjab (1966–67 to 2014–15)

While rice and wheat occupied 90.1% of the area in Punjab and contributed 76.9% towards production in 2014–15, the combined area under other crops, which in 1966–67 was 54.54%, has decreased drastically to 9.87% in 2014–15. This changing cropping pattern is of key significance for the present state and future prospects of Punjab economy.
