The Fourth Assessment Report of Intergovernmental Panel on Climate Change described scenarios that by 2100 mean planet-wide surface temperature will likely rise by 1.4 to 5.8°C, precipitation will decrease and extreme events will become more frequent (IPCC, 2007).

Among the different abiotic stresses, heat, drought, submergence, and salinity are the major factors affecting rice ecosystem and are responsible for significant annual economic losses to rice producers. The International Food Policy Research Institute (IFPRI) report Climate Change: Impact on Agriculture and Costs of Adaptation forecasts that by 2050 rice prices will increase between 32 and 37% as a result of climate change. They also show that rice productivity will reduce by 14% in South Asia, 10% in East Asia and the Pacific, and 15% in Sub-Saharan Africa (IFPRI,
