Mongolia and changes in crop, farming systems and crop areas in almost all regions, with negative implications to food security . In India, rice production can decrease from 10 to 30%, whereas maize production can decrease from 25 to 70% assuming a range of temperature increase from 1ºC to 4ºC. Similarly, rice production in Cambodia can decrease by 45% by 2080 under the high-emissions scenario. Occurrence of pests, such as the golden apple snail , associated with the predicted increase in climatically suitable habitats in 2080, threatens the top Asian rice- producing countries including China, India, Indonesia, Bangladesh, Vietnam, Thailand, Myanmar, the Philippines and Japan. Increasing temperatures, changing precipitation levels and extreme climate events, such as heatwaves, droughts and typhoons, will persist in being important vulnerability drivers that will shape agricultural productivity particularly in South, Southeast and Central Asia.
