In India, swapping crops could save water and improve nutrition

(The Earth Institute at Columbia University) India will need to feed approximately 394 million more people by 2050. Meanwhile, many of its regions are chronically water-stressed, and nutrient deficiencies are widespread -- 30 percent of Indians or more are anemic. 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.
