Impact of Climate Change on Yields of Major Food Crops in India: Implications for Food Security

摘要: The study has analysed changes in climate variables, viz. temperature and rainfall during the period 1969–2005 assessed their impact on yields of important food crops. A significant rise was observed mean monthly temperature, but more so post-rainy season. rainfall, however, were not as significant. While an increase maximum found to have adverse effect crop yields, a similar minimum had favourable most crops, it sufficient fully compensate damages caused by temperature. Pigeonpea, rice, chickpea wheat vulnerable Rainfall positive could counterbalance negative projections impacts towards 2100 suggested that with rice yield will be lower 15 per cent 22 cent. Coarse cereals affected less, while pulses than cereals. If are significant, crops smaller. In short-run too severe.
