Every year, South Asian countries suffer from declining agricultural outputs due to climate extremes such as floods and droughts. Recurrent droughts have depressed rural economies enhanced widespread hunger human migration cities (Miyan, 2015). Due climatic changes, the region is projected experience rising temperatures more frequent extreme weather events in long term (Trenberth et al., 2014)....
China’s role on the global grain market is expected to increase as the demand for food and feed grows, both within and outside the country. This role could also be affected by unexpected crop failures caused by natural hazards. This paper uses agricultural production (rice, wheat, maize, tubers, soybeans and other grains) and natural hazards data (floods and droughts) for 31 provinces in China ...

Increasing heatwave and drought events can potentially alter the carbon cycle. Few studies have investigated the impacts of hundred-year return heatwaves and droughts, as those events are rare. In the summer of 2013, southern China experienced its strongest drought and heatwave on record for the past 113 years. We show that the record-breaking heatwave and drought lasted two months (from July t...
Recently the Southwest has experienced a spate of dryness, which presents a challenge to the sustainability of current water use by human and natural systems in the region. In the Colorado River Basin, the early 21st century drought has been the most extreme in over a century of Colorado River flows, and might occur in any given century with probability of only 60%. However, hydrological model ...
This study analyzes the changes in drought patterns in China’s major crop-growing areas over the past 60 years. The analysis was done using both weather station data and Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) rainfall data to calculate the Standardized Precipitation Index (SPI). The results showed that the occurrences of extreme drought were the most serious in recent...
