Ecosystem And Biodiversity Of Amazonia

The Amazonia is the largest continuous river basin and rainforest ecosystem in the world. In all aspects it is a natural wonder, and the rainforest with its billions of trees is a vital carbon store that slows down the advance of global warming. It is home to one million indigenous people and some three million species of plants and animals. There have been many climate fluctuations during the last 55 million years of its existence, but never before have “the lungs of the world” been at greater risk than they are today due to uncontrolled fires, expanding agriculture and heavy industrial development in the forms of oil drilling, mining and large hydroelectric dams. Over twelve chapters, this book describes the anthropological, biological and industrial problems facing the Amazonia, and seeks to find new solutions.

The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.

This book provides an analysis of the recent governance of the Amazon in Brazil, Peru, Bolivia and Colombia with a particular focus on deforestation processes, demonstrating that current policies and political and socioeconomic dynamics in the four countries are risking the forest’s resilience. The authors examine and compare Amazonian politics and policies under different administrations, concentrating on the main actors, policies and dynamics that have affected the region, as well as on the institutional and political environment in which deforestation processes were embedded in different periods. Essentially, the book makes an analytical contribution towards a better understanding of the political, economic and social challenges confronting conservation policy in the Amazonian countries. Climate Change and Biodiversity Governance in the Amazon: At the Edge of Ecological Collapse? is essential reading for students and researchers in the fields of environmental studies and sustainability, Latin American studies, political science and international relations, as well as for policymakers and practitioners working in conservation and development.

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.

This book offers a panorama of recent scientific achievements produced through the framework of the Large-Scale Biosphere-Atmosphere programme (LBA) and other research programmes in the Brazilian Amazon. The content is highly interdisciplinary, with an overarching aim to contribute to the understanding of the dynamic biophysical and societal/socio-economic structure and functioning of Amazonia as a regional entity and its regional and global climatic teleconnections. The target readership includes advanced undergraduate and post-graduate students and researchers seeking to untangle the gamut of interactions that the Amazon’s complex biophysical and social system represent.

The Amazon Basin contains the largest and most diverse tropical rainforest in the world. Besides the Andes and the Atlantic Ocean, the rainforest is bounded to the north by the Guiana crystalline shield and to the south by the Brazilian crystalline shield, marked at their edges by cataracts in the rivers and often dominated by grasslands. This book is motivated not just by the Amazon's scientific interest but also by its role in many ecosystem functions critical to life on Earth. These ecosystems are characterized both by their complexity and their interactive, higher-order linkages among both abiotic and biotic components. Within Amazonia, the Western Amazon (west of 65° latitude) is the most pristine and, perhaps, the most complex within the Amazon Basin. This Western Amazon may be broadly divided into non-flooded forests (e.g. terra firme, white sand, palm) and forests flooded with white water (generally referred to as várzea) and with black water (generally referred to as igapó). Here, for the first time, is a book devoted entirely to Western Amazonia, containing chapters by scientists at the forefront of their own areas of expertise. It should be a valuable resource for all future researchers and scholars who venture into Western Amazonia, as it continues to be one of the most beautiful, mysterious, remote and important ecosystems on Earth.

A fundamental and comprehensive reformulation of how we value nature and the services it provides as the basis on which all economic activity depends.

This timely book provides the first examination of the relationship between cultural and environmental variation in the Amazon, with special reference to the survival and welfare of indigenous societies. The particular strength of this collection is that it emphasizes ongoing changing elements rather than static ones in Amazonian human ecology in the context of colonization. Leslie Sponsel and twelve other contributors, including archaeologists, biological anthropologists, cultural ecologists, and nutritionists, review traditional and changing adaptations of indigenous societies to Amazonian ecosystems; they analyze the challenges presented to indigenes by the massive cultural and environmental impact of Westernization. They also discuss the applications of research results to the needs, interests, and priorities of indigenous societies. In his concluding chapter, Sponsel calls for anthropologists to contribute through their research to the empowerment of indigenous communities and organizations. "In the Amazon the only people who already know and practice ecologically sound economies are most indigenous societies. Documenting their ecologically sound values, knowledge, and technology is one of the most important tasks for cultural ecology".
