Book Description
The future of Brazilian Amazonia, the world's largest remaining tropical rainforest, hangs in the balance. Two decades of destructive development have provoked violent struggles for control over the region's resources, with disastrous social and environmental consequences. This multi-disciplinary collection reviews past experience but focusses on the latest phase of Amazonian settlement. Chapters by leading authorities examine such issues as colonisation in the most recent frontier areas, multinational mining projects, hydro-electric schemes, and the military occupation of Brazil's borders. After demonstrating how new government and business activities have exacerbated social tensions and ecological destruction, the volume considers alternative, more sustainable strategies.

Book Description
Cultivated Landscapes of Native Amazonia and the Andes examines Indian agriculture in South America. The focus is on field types and field technologies, including agricultural landforms such as terraces, canals, and drained fields, which have persisted for hundreds of years. What emerges is a picture of mostly successful indigenous farming practices in difficult environments--rain forests, savannahs, swamps, rugged mountains, and deserts.

Book Description
Nearly 90 percent of agricultural land in the Brazilian Amazon is used for pasture, or has been cleared and left unused. Pasture on average is used with very low productivity. Analysis based on census tract data shows that agricultural conversion of forested areas in the wetter western Amazon would be even less productive, using current technologies.

Book Description
The experiments and experiences discussed in Soil Management carefully document crop production systems with well-defined boundaries. These long-term agronomic trials provide a valuable data resource that has, until now, been largely ignored by both the research community and the sustainability experts. With a rigorous definition of sustainability and this data, the sustainability of various cropping systems will be more clearly illustrated than any previous effort. Particular emphasis is given to research involving the tropics and sub-tropics. This book is unique in providing an experimental basis for sustainable management of soil resources. It describes technological options for sustainable management of soil resources and identifies priorities for additional long-term experimentation needed in key ecoregions. Topics discussed include changes in soil processes and properties, environmental quality, soil management, soil dynamics, soil organic matter, and nutrient cycling. Soil Management is for those who ask whether agriculture is sustainable, want to analyze or review sustainability experiments and experiences, or wish to initiate new long-term trials. It is a valuable reference on soil processes and an excellent text for courses in soil management.

Book Description
The Amazon -that name was given to the biggest river on earth and is often used for the whole area of its basin too. This geographical region is currently referred to as Amazonia, thus emphasizing the peculiar character of its aquatic and terrestrial reaches. The Amazon embodied the dream of many a naturalist to explore what for a long time was a terra incognita. In recent years, however, Amazonia has emerged as a main centre for 'development' by some of the countries in which it lies and by foreign industrialized nations. The development projects and enterprises have aroused woridwide interest and have given rise to discussions on their aims and their consequences to the Amazonian nature. Limnological and ecological investigations in Amazonia started only about 40 years ago. The editor had the good fortune to partake in them from the very beginning. He spent his decisive years in Amazonia, and dedicated his life's work to that research and to that country and the Amazonian people. Nearing the end of his scicntific activities, hc is gratcful to bc ablc to summarizc in this book most of the knowledge we possess at present of Amazonian limnology and landscape ecology.

Book Description
In this well-written, comprehensive, reasonable yet passionate volume, Emilio Moran introduces us to the range of human and ecological diversity in the Amazon Basin. By describing the complex heterogeneity on the Amazon's ecological mosaic and its indigenous populations' conscious adaptations to this diversity, he leads us to realize that there are strategies of resource use which do not destroy the structure and function of ecosystems. Finally, and most important, he examines ways in which we might benefit from the study of human ecology to design and implement a balance between conservation and use.
