COVER Bags of rice await export from India to Europe. As the global population climbs to a projected peak of some 9 billion in 2050, concerns about food security are growing. A special section beginning on page 797 examines the causes of food insecurity and some solutions, and the implications of climate change and energy use for feeding the world.
