The world faces the complex challenge of providing nutritious and affordable food to a rising population expected to reach 9 billion by 2050, without depleting scarce natural resources. In the past, efforts to increase availability of food have led to expanding agriculture, standing in conflict with other land uses. More than 50 percent of Earth’s forests have now disappeared, creating an array of environmental and social problems. Yet, more than one third of the food produced worldwide is going to waste.
