West Africa: Deadly cycle of malnutrition and disease

The United Nations on Monday marked World Food Day to call attention to the 850 million hungry people around the world, almost half of them children who are locked in a cycle of malnutrition and disease. Led by the Food and Agriculture Organisation (FAO), the theme for this year is investing in agriculture for food security. The semi-arid Sahel region of West Africa is amongst the most food insecure regions in the world.
