Billions of people around the world rely on rice as a mainstay of their diet. The grain provides about 20 percent of the calories consumed by humans worldwide. Rice production is critical for global food security, and demand will only grow as the world’s population expands by an estimated 2-3 billion by 2050. To keep up, farmers will need new strains of rice that can be grown both efficiently and sustainably, in new environments and in a changing climate.
