Malnutrition in all its forms – undernutrition, micronutrient deficiencies, and overweight and obesity – imposes unacceptably high economic and social costs on countries at all income levels. Improving nutrition and reducing these costs requires a multisectoral approach that begins with food and agriculture and includes complementary interventions in public health and education. The traditional role of agriculture in producing food and generating income is fundamental, but the entire food system – from inputs and production, through processing, storage, transport and retailing, to consumption – can contribute much more to the eradication of malnutrition.
Agricultural policies and research must continue to support productivity growth for staple foods while paying greater attention to nutrient-dense foods and more sustainable production systems. Traditional and modern supply chains can enhance the availability of a variety of nutritious foods and reduce nutrient waste and losses. Governments, international organizations, the private sector and civil society can help consumers choose healthier diets, reduce waste and contribute to more sustainable use of resources by providing clear, accurate information and ensuring access to diverse and nutritious foods.
