Food systems are climate and weather dependent; heat stress and changes in rainfall patterns and relative humidity are likely to regulate crop yields. Elevated carbon dioxide (CO2) are likely to directly and indirectly bring new challenges to the stability and sustainability of global food production including rice.
This report provides a brief overview of projected rice security indicated by future potential yield under elevated carbon dioxide levels. This research aims to identify the downscaled impact of climate change on rice production which includes climate change impact assessment at sub-national levels in the world’s top three rice exporters namely Thailand, Vietnam and India.
This paper also identifies some of the downscaled impacts of climate change that may continue to affect rice production in these regions until the end of the 21st century. The authors also identify public actions and policy responses in India, Thailand and Vietnam.
