Amazonia and Global Change
Author: Michael KellerPublisher: John Wiley & Sons
ISBN: 1118671511
Category : Science
Languages : en
Pages : 1472
Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 186. Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change. LBA, led by Brazil, asks how Amazonia currently functions in the global climate and biogeochemical systems and how the functioning of Amazonia will respond to the combined pressures of climate and land use change, such as Wet season and dry season aerosol concentrations and their effects on diffuse radiation and photosynthesis Increasing greenhouse gas concentration, deforestation, widespread biomass burning and changes in the Amazonian water cycle Drought effects and simulated drought through rainfall exclusion experiments The net flux of carbon between Amazonia and the atmosphere Floodplains as an important regulator of the basin carbon balance including serving as a major source of methane to the troposphere The impact of the likely increased profitability of cattle ranching. The book will serve a broad community of scientists and policy makers interested in global change and environmental issues with high-quality scientific syntheses accessible to nonspecialists in a wide community of social scientists, ecologists, atmospheric chemists, climatologists, and hydrologists.
Forest Structure, Function and Dynamics in Western Amazonia
Author: Randall W. MysterPublisher: John Wiley & Sons
ISBN: 1119090695
Category : Science
Languages : en
Pages : 243
Book Description
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.
Amazonia: Landscape and Species Evolution
Author: Carina HoornPublisher: John Wiley & Sons
ISBN: 1444360256
Category : Science
Languages : en
Pages : 869
Book Description
The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.
Indigenous Amazonia, Regional Development and Territorial Dynamics
Author: Walter Leal FilhoPublisher: Springer Nature
ISBN: 3030291537
Category : Social Science
Languages : en
Pages : 433
Book Description
This book brings together a valuable collection of case studies and conceptual approaches that outline the present state of Amazonia in the 21st century. The many problems are described and the benefits, as well as the achievements of regional development are also discussed. The book focuses on three themes for discussion and recommendations: indigenous peoples, their home (the forest), and the way(s) to protect and sustain their natural home (biodiversity conservation). Using these three themes this volume offers a comprehensive critical review of the facts that have been the reality of Amazonia and fills a gap in the literature.The book will appeal to scholars, professors and practitioners. An outstanding group of experienced researchers and individuals with detailed knowledge of the proposed themes have produced chapters on an array of inter-related issues to demonstrate the current situation and future prospects of Amazonia. Issues investigated and debated include: territorial management; indigenous territoriality and land demarcation; ethnodevelopment; indigenous higher education and capacity building; natural resource appropriation; food security and traditional knowledge; megadevelopmental projects; indigenous acculturation; modernization of Amazonia and its regional integration; anthropogenic interventions; protected areas and conservation; political ecology; postcolonial issues, and the sustainability of Amazonia.
Amazonian Dark Earths
Author: Johannes LehmannPublisher: Springer Science & Business Media
ISBN: 1402025971
Category : Technology & Engineering
Languages : en
Pages : 510
Book Description
Dark Earths are a testament to vanished civilizations of the Amazon Basin, but may also answer how large societies could sustain intensive agriculture in an environment of infertile soils. This book examines their origin, properties, and management. Questions remain: were they intentionally produced or a by-product of habitation. Additional new and multidisciplinary perspectives by leading experts may pave the way for the next revolution in soil management in the humid tropics.

Ecosystems and Land Use Change
Author: Ruth DeFriesPublisher: American Geophysical Union
ISBN: 9780875904184
Category : Science
Languages : en
Pages : 360
Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 153. Land use is at the center of one of the most vexing challenges for the coming decades: to provide enough food, fiber and shelter for the world's population; raise the standard of living for the billion people currently below the poverty line; and simultaneously sustain the world's ecosystems for use by humans and other species. The intended consequence of cropland expansion, urban growth, and other land use changes is to satisfy demands from the increasing appetite of the world's population. Unintended consequences, however, can alter ecological processes and have far-reaching and long-term effects that potentially compromise the basic functioning of ecosystems. Recently, the scientific community has begun to confront such issues. Several national and international programs have been at the forefront of scientific enquiry on the causes and consequences of land use change, including: the Land Use and Land Cover Change Program of the National Aeronautics and Space Administration, the Land Use program element in the interagency U.S. Climate Change Science Program, and the International Geosphere-Biosphere's Land Use and Cover Change (LUCC) core project. The result has been significant advances in understanding the complex socioeconomic, technological, and biophysical factors that drive land use change worldwide.
