Developing countries are suffering from the multiple and overlapping problems of poverty, malnutrition, excessive population growth and also the increased environmental pollution due to rapid industrialization and urbanization, particularly in the existing urban centres. The migration from rural areas of agricultural population to urban areas is making this situation more problematic. The lack of established institutions leads to the failure of public policy no matter how efficiently it is formulated. The book discusses the major regional developmental problems in poor countries, covering economic, social and environmental problems. It deals with case-studies for a set of individual countries, and discusses their unique problems, investigating how the established methods of regional science can be used to solve some of these problems.
