Rice is a staple food for millions across Southeast Asia, where intensive subsistence rice farming commonly occurs. Traditional rice cultivation involves flooding small rice paddies surrounded by earthen embankments for part of the year, creating a landscape of interconnected paddies, canals, and settlements on higher ground. Farmers plant seeds in nursery beds, transplant seedlings by hand during flooding, and gradually drain the paddies before harvesting rice and cultivating off-season crops, supported by fish, livestock, and trees throughout the farming system.
