SUMMARY:Seminar :Global warming and local air pollution have reduced wheat yields in India
DESCRIPTION:Abstract\n\nWe use regression analysis on data from 208 districts over the period 1981-2009 to examine the impact of temperature and solar radiation (affected by pollution from aerosols) on wheat yields in India. We find that a 1°C increase in average daily maximum and minimum temperature tends to lower yields by 2-3% each. A 1% increase in solar radiation increases yields by nearly 1%. Yields are estimated to be about 5% lower than they would have been if temperatures had not increased during the study period. We combine the estimated impacts of weather on yield with the estimated impacts of aerosol pollution (measured by MODIS sensor in terms of aerosol optical depth\, AOD in 2000-2013) on weather to compute the net impact of reducing aerosol pollution on wheat yields. A one-standard-deviation decrease in AOD is estimated to increase yields by about 4.5%. Our results imply wheat yield losses can be countered by reducing regional pollution and curbing global warming in the coming decades.\n\n \n\nSpeaker : Dr Ridhima Gupta
