Tackling the adverse effects of global warming on Indian agriculture

Abstract

Agriculture is the backbone of Indian economy which in turn relies on the monsoon season. The Intergovernmental Panel on Climate Change (IPCC) projected that the global mean surface temperature will likely rise and may result into uneven climatic changes such as irregular rainfall patterns, increased surface temperature and elevated CO2 content in the atmosphere. Research studies indicate that weathering parameters influence strongly (67%) compared to other factors like soil and nutrient management (33%) during the cropping season. Researchers have confirmed that crop yield falls by 3-5% for every 1°F increase in the temperature. Present study shows that the crop production is dependent on temperature and shows a funnel shape for all the seasons. At lower temperature both the properties are almost linearly correlated, whereas at higher temperatures, it increases but with large scattering. The findings may be helpful to study the effect of climate change on the crop production.
