How to fix the global rice crisis
The world’s most important crop is fuelling climate change and diabetes
The green revolution was one of the greatest feats of human ingenuity. By promoting higher-yielding varieties of wheat and, especially, rice, plant-breeders in India, Mexico and the Philippines helped China emerge from a famine and India avoid one. From 1965 to 1995 Asia’s rice yields doubled and its poverty almost halved, even as its population soared.
Asia’s vast rice market is a legacy of that triumph. The starchy grain is the main source of sustenance for over half the world’s population. Asians produce over 90% of rice and get more than a quarter of their calories from it. And demand for the crop is projected to soar, on the back of population growth in Asia and Africa, another big rice consumer. By one estimate, the world will need to produce almost a third more rice by 2050. Yet that looks increasingly hard—and in some ways undesirable.
