All over the world, small-scale farmers are finding ways to increase their production by managing water more efficiently. They are on the frontlines in the fight against hunger. Rice feeds nearly 4 billion people—it is the most widely grown cereal crop in the world. Often cultivated by hand, mainly by small farmers to feed their families, rice farming is highly water-intensive.
But bold farmers are testing a new cultivation method that doubles yields while using far less water. The technique is surprisingly simple: replant young shoots just two or three weeks after the rice grains have germinated. This allows them to resume growing immediately, accelerating their development. Traditionally, rice is grown in flooded fields to suppress weeds. However, it thrives even better when the soil is not submerged. Well-oxygenated roots grow faster and stronger.
Feeding these growing populations will depend on a multitude of local solutions—adapted to climate, soil, and crop type.
