A study on https://exam.pscnotes.com/Climate-change”>Climate Change and its impact on productivity of major kharif and Rabi Crops in Punjab, has indicated that productivity of most crops decreases with an increase in Average temperature and has suggest focus on Agriculture-notes-for-state-psc-exams”>Agriculture“>Climate-Smart Agriculture for effective solutions to climatic risks.
The study assessed the climate change impact on productivity for five major crops across Punjab over a 35 year period from 19862020. These include wheat, rice, Cotton, maize and potato.
Anticipating that the climate change would be long-standing and will have a great bearing on the livelihood of the farmers and overall economy of the sector, the study observed that the projected changes in temperature and rainfall may result in a decline in yield of all major crops in the range of 1-10 percent by 2035, 3-18 percent by 2065, and 4-26 percent by the year 2100.
According to the experts calculations, by 2050, the loss in yield, including negative impact accumulating over time, would be 24 per cent formaize, followed by 24 per cent for cotton and by about two per cent for rice. The yield loss of wheat and potato has been projected at five per cent each.
