Rapid population growth, increased demand for food and other natural resources, and political and socioeconomic stresses have all contributed to the worldwide development of marginal regions—fringe areas, boundaries, and frontier zones. In this book, contributors analyze the limitations and opportunities provided by the natural and human environments of different marginal regions and compare human and resource management approaches. They also offer potential strategies and policies that may lead to more successful spatial planning and more rational human activity in ecologically vulnerable areas.
