CSA News 11 Rice is our most important staple food crop. It is grown in diverse agroclimatic zones from temperate through subtropical to tropical, with temperature being the principle limiting factor to cultivation: critical limits range from 12 to 20°C in cool zones to 34 to 38°C in warmer ones. Productivity is affected as these extremes are approached. According to the Intergovernmental Panel on Climate Change, mean global surface temperature is expected to increase by 0.6 to 4°C by 2100 with an increase in temperature variability and, importantly for grain production, more frequent extreme events. Moreover, increasing demand for rice is pushing rice production into a wider range of environments.
