Many people are suspicious of GM crops, but new techniques could massively increase food production.
How can we feed a growing world population while protecting the environment? One key strategy is to improve yields on small farms, which produce much of the food in the world's hungriest countries.
Nearly two-thirds of the billion people suffering food insecurity are themselves farmers. Here's how some are protecting themselves.
