Punjab's cotton, maize yield to dip by 11-13% by 2050 due to climate change

Climate change is predicted to reduce maize and cotton yield in Punjab by 13 per cent and 11 per cent by 2050, according to a new study conducted by agriculture economists and scientists at Punjab Agricultural University (PAU). Punjab accounts for around 12 per cent of the total cereals produced in the country. The study published in the Mausam journal of the India Meteorological Department earlier this month used rainfall and temperature data collected between 1986 and 2020 to project the impact of climate change on five major crops -- rice, maize, cotton, wheat, and potato -- in the agrarian state. The researchers collected climate data from five weather observatories of Punjab Agricultural University, ie Ludhiana, Patiala, Faridkot, Bathinda, and SBS Nagar. The researchers -- agricultural economist Sunny Kumar, scientist Baljinder Kaur Sidana and PhD scholar Smily Thakur -- said that long-term changes in climatic variables show that the rise in temperature is driving most of the
