This book examines the global campaign to end hunger and malnutrition. Focus is placed on the work of the United Nations which has led international efforts to improve food security in the world's poorest countries. The book first reviews the long-term project to establish access to safe, sufficient, and nutritious food as a universally recognized human right. This is followed by separate chapters that examine the nature and central causes of food insecurity in Latin America, Africa, the Middle East, and Asia. These chapters also review the contemporary work of three United Nations agencies – the World Food Programme, Food and Agriculture Organization, and International Fund for Agricultural Development – in providing both food aid and food assistance to each region of the developing world. This includes the provision of emergency food aid in response to natural disaster and civil conflict, as well as longer-term food assistance to promote agricultural productivity, advance rural development, and preserve natural environments. The concluding chapter considers ways to strengthen food aid and assistance in the years to come, with many of the recommendations advanced reflecting lessons learned from the actual experience of food aid and assistance described in this book.
