The increase in the world population and changes in welfare have led to an enormously expanding demand for food. In the industrialized world, food surpluses rather than shortages are a problem together with adverse environmental impacts from the overuse of chemicals and excessive exploitation of agricultural land. In the developing world, food production cannot keep up with population growth and the gap between demand and supply is growing. This book explores the theme of sustainable agricultural development in the developing world, with a particular focus on crop protection. Includes chapters on the ecology of food production, on sustainable agriculture and crop protection methods, on the economics of food production and more.
