Climate change and crop breeding objectives in the twenty first century

摘要

The earth’s climate system is experiencing a warmer phase. Concomitantly, India is facing a climate change of considerable magnitude. Recently, researchers have projected region-wise scenarios of rainfall and temperature changes, impact on hydrologyof river basins and consequences for India in the twenty-first century respectively. High-resolution climate change predictions, based on the Re-gional Climate Modelling (RCM) system PRECIS (Providing Regional Climate for Impact Studies) developed by Hedley Center, envisage that as the twenty-first century progresses, there will be (i) rise in temperature ranging from 2 to 6°C.
