As the threats of food insecurity loom ever larger, the world faces the sad irony of food shortages in the global South alongside a purported 'obesity epidemic' in the global North. The twin issues of food production and food access are of particular concern in the context of climate change, 'peak oil', biofuels, and land grabs by wealthy nations. Food Security, Nutrition and Sustainability offers critical insights by international scholars, with chapters on global food security, supermarket power, new technologies, and sustainability. The book also assesses the contributions of diet and nutrition research in building socially just and environmentally sustainable food systems and provides policy recommendations to improve the health and environmental status of contemporary agri-food systems. The book features contributions from a range of social science perspectives, including sociology, anthropology, public health and geography, with case study material drawn from throughout the world.
