This book focuses on the global effects of land degradation, but emphasises other important levels of land degradation: at the field level, it may result in reduced productivity; at the national level, it may cause flooding, and sedimentation; and, at the global level, it can contribute to climate changes, damaging bio-diversity, and international waters. The effects on climate changes are explored, and the report questions the extent to which land degradation on agricultural land, affects climate change. Does it increase emissions of greenhouse gases? Does it affect land's capacity to...

Mexico leads the world in community management of forests for the commercial production of timber. Yet this success story is not widely known, even in Mexico, despite the fact that communities around the globe are increasingly involved in managing their own forest resources. To assess the achievements and shortcomings of Mexico's community forest management programs and to offer approaches that can be applied in other parts of the world, this book collects fourteen articles that explore community forest management from historical, policy, economic, ecological, sociological, and political...

By the middle of the nineteenth century, however, Virginia's leadership in the American coal industry had completely unraveled while Pennsylvania, at first slow to exploit its vast reserves of anthracite and bituminous coal,...

Wood was essential to the survival of the Venetian Republic. To build its great naval and merchant ships, maintain its extensive levee system, construct buildings, fuel industries, and heat homes, Venice needed access to large quantities of oak and beech timber. The island city itself was devoid of any forests, so the state turned to its mainland holdings for this vital resource. A Forest on the Sea explores the history of this enterprise and Venice's efforts to extend state control over its natural resources.

Karl Appuhn explains how Venice went from an isolated city...
