In India, swapping crops could save water and improve nutrition
India will need to feed approximately 394 million more people by 2050, and that’s going to be a significant challenge. Nutrient deficiencies are already widespread in India today—30 percent or more are anemic—and many regions are chronically water-stressed. Making matters worse, evidence suggests that monsoons are delivering less rainfall than they used to. But a study published today in Science Advances shares a brighter outlook: replacing some rice with less thirsty crops could dramatically reduce water demand in India, while also improving nutrition.
