Destructive patterns of Amazonian evolution are now infecting relatively untouched Northern Brazil - driven by the gold rush and demographic and economic forces from the South. The Forest Frontier assesses whether the Northern Amazonian States can avoid the same pressures and problems that affect the peoples and environments of the South. It examines the social and environmental nature of land development in Roraima, the most northerly of the Brazilian Amazonian states. Possessing most of the classic problems facing other States as well as containing a combination of political, cultural and environmental features, Roraima's development is at a frontier. Offering a critical assessment of the nature and pace of agricultural advance into Roraima, The Forest Frontier will provide a better understanding to plan for the inevitable development to come.

From the pre-Columbian era to the present, native Amazonians have shaped the land around them, emphasizing utilization, conservation, and sustainability. These priorities stand in stark contrast to colonial and contemporary exploitation of Amazonia by outside interests. With essays from environmental scientists, botanists, and anthropologists, this volume explores the various effects of human development on Amazonia. The contributors argue that by protecting and drawing on local knowledge and values, further environmental ruin can be avoided.

The floodplain forests of the Amazon, the world's largest river, are among the most threatened habitats in South America. Yet little is known about how these unique, seasonally flooded forests were used in the past, or their current importance to farmers, livestock owners, and fisherfolk. This book explores the natural history knowledge of the floodplain inhabitants and how we might better use their knowledge to promote sound conservation and development policies.

Few tropical ecosystems have been subjected to multi-disciplinary investigations as broad and exhaustive as those carried out on the Ilha de Maraca, a riverine island in the Brazilian Amazon. This diverse and remarkable ecological reserve, in Brazil s northernmost Amazon state of Roraima, includes environments and habitats ranging from rainforests and semi-deciduous forests to natural savannas, lakes, rivers and palm swamps. These have been subjected to an in-depth international scientific study whose primary aim was to undertake one of the most detailed ecological surveys ever conducted in Amazonia. The results of this enormous body of research, involving the collaborative fieldwork of some 200 workers, span the reserve s geology, geomorphology, botany, zoology, phenology, soils, limnology, ecology and historical human occupation. These have been carefully drawn together in this volume in such a manner as to provide not only a coherent and scholarly picture of an unique and fascinating environment, but also an important and enduring source of reference for a broad spectrum of disciplines to the Amazon environment. This book is a timely reminder of the crucial importance of our understanding of rainforest components and their interrelationships, appearing as it does at a period when there is an intense interest in this extremely endangered ecosystem.

Provides syntheses of studies in three continents on the problem of achieving and understanding tropical rural development without compromising longer-term sustainability of the soil and water systems that underpin it. The studies were carried out in Central/South America, Africa and Asia during the 1990s, mostly through the support of the EU Science and Technology for Development Programme. The studies encompass examples of erosion measurement:; of erosion control and conservation techniques at soil and ecosystem levels; of the limits to uses of fragile tropical soils; of the effects of runoff combined with regulation on rivers and reservoirs; of the importance of indigenous people in the development processes and of the value and limitations of modelling at scales from soils to catchment. There is no single message from the book because there is no single solution to the problems of achieving sustainable tropical development. This book presents ideas, techniques and case studies, knowledge of which will help researchers in many scientific and social disciplines to understand the complexities better, and politicians and bureaucrats to understand the consequences of development decisions and learn from the failure of many earlier ones.
