Rainfed rice field in ASEAN Countries occupies an area of 19.8 million hectares, representing 49.2% of the total rice cultivation area of ASEAN. This area is used only 4-5 months per year with single cultivation while for the rest, 7-8 months, the land is left fallow. This research work focused on the assessment and identification of strategic rice cultivation practices including rotation with energy crops to contribute to global warming mitigation and adaptation to climate change and enable SEA to develop towards a self-sufficient low-carbon society. It was found that energy crop rotation with rice is a good strategy to reduce GHG emissions and contribute to increasing soil carbon in the long run. Expansion of this strategy to SEA is not only enabling to enhance the biomass resources for biofuel and bioenergy with no impact on food crops, but also to contribute to reducing issues of competition between food and fuel crops as well as land use change problem. Moreover, this strategic practice may contribute to increasing the potential of carbon sink and moving toward poverty eradication. However, the market of energy crop is a major driver for adoption of this practice, and the formulation and implementation of clear policies on renewable energy and biomass utilisation is therefore necessary and should be strongly promoted in each SEA country.
