Increasing Concurrent Drought Probability in Global Main Crop Production Countries

چکیده
Understanding concurrent drought events in global main croplands is crucially important for food security, effective adaptation to climate change and human well-being. Yet, there a lack of comprehensive studies on probability changes among crop production countries scale, especially the future. Here, we studied 26 time period 1861–2099. During historical period, moderate severe was relatively low, maximum will double triple under RCP8.5 extreme climate, respectively. Concurrent between China United States America, Brazil Russia be at least 6% 5% RCP8.5, respectively, compared with zero period. Limiting RCPs RCP2.6 can decrease 2% (at 3% RCP8.5).

Drought Frontiers in Rice: Crop Improvement for Increased Rainfed Production
The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...
