This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biodiverse Amazon rainforest biome is the world's largest rainforest ecosystem and plays an essential role for global climate, carbon budget, and the hydrological cycle. In the light of future climate change the effects of rising temperatures and changing precipitation on Amazonian biodiversity is a major point of interest. In addition to climate change forest fragmentation is one of the biggest threats the Amazonian rainforest has to suffer, besides the growing pressure of human land use. In which way future global warming would induce species extinctions and ecosystem turnovers is the...

Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

Download or read book Past Climate Variability in South America and Surrounding Regions written by Francoise Vimeux and published by Springer Science & Business Media. This book was released on 2009-08-04 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: South America is a unique place where a number of past climate archives are ava- able from tropical to high latitude regions. It thus offers a unique opportunity to explore past climate variability along a latitudinal transect from the Equator to Polar regions and to study climate teleconnections. Most climate records from tropical and subtropical South America for the past 20,000 years have been interpreted as local responses to shift in the mean position and intensity of the InterTropical Conv- gence Zone due to tropical and extratropical forcings or to changes in the South American Summer Monsoon. Further South, the role of the Southern Hemisphere westerly winds on global climate has been highly investigated with both paleodata and coupled climate models. However the regional response over South America during the last 20,000 years is much more variable from place to place than pre- ously thought. The factors that govern the spatial patterns of variability on millennial scale resolution are still to be understood. The question of past natural rates and ranges of climate conditions over South America is therefore of special relevance in this context since today millions of people live under climates where any changes in monsoon rainfall can lead to catastrophic consequences.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Brazilian Amazon written by Joana Bezerra and published by Springer. This book was released on 2016-10-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to analyse the current development scenario in the Amazon, using Terra Preta de Índio as a case study. To do so it is necessary to go back in time, both in the national and international sphere, through the second half of the last century to analyse its trajectory. It will be equally important analyse the current issues regarding the Amazon – sustainable development and climate change – and how they still reproduce some of the problems that marked the history of the forest, such as the absence of Amazonian dark earths as a relevant theme to the Amazon. In a world in which the environment gains each time more space in the national and international political agenda, the Amazon stands out. Known around the world for its richness, the South-American forest is the target of different visions, often contradictory ones, and it plays with everyone’s imagination. This is where the terra preta de índio – Amazonian Dark Earths - are found, a fertile soil horizon with high concentrations of carbon with anthropic origins, which has generated great interest from the scientific community. Studies on these soils and their so singular characteristics have triggered crucial discussions on the past, present and the future of the entire Amazon region. Despite its singular characteristics, the importance of Amazonian Dark Earths – and a history of a more productive and populated Amazon – was hidden since its discovery around 1880 until 1980, when it is possible to identify the beginning of an increase in the number of research on these soil horizons. These hundred years between the first records and the beginning of the increase in the interest around these soils witnessed structural changes both in the national arena, with the military dictatorship and a change in the place of the Amazon within internal affairs, and in the international arena with changes that reshaped the role of the environment in the political and scientific agendas and the role of Brazil in the global context.
Download or read book Guardians of the Brazilian Amazon Rainforest Environmental Organizations and Development written by Luiz C. Barbosa and published by Routledge. This book was released on 2015-05-08 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Amazon region is the focus of intense conflict between conservationists concerned with deforestation and advocates of agro-industrial development. This book focuses on the contributions of environmental organizations to the preservation of Brazilian Amazonia. It reveals how environmental organizations such as Greenpeace, Friends of the Earth, WWF and others have fought fiercely to stop deforestation in the region. It documents how the history of frontier expansion and environmental struggle in the region is linked to Brazil’s position in an evolving capitalist world-economy. It is shown how Brazil’s effort to become a developed country has led successive Brazilian governments to devise development projects for Amazonia. The author analyses how globalization has led to the expansion of international commodity chains in the region, particularly for mineral ores, soybeans and beef. He shows how environmental organizations have politicized these commodity chains as weapons of conservation, through boycotting certain products, while other pro-development groups within Brazil claim that such organizations threaten Brazil's sovereignty over its own resources.

Available in PDF, EPUB and Kindle. Book excerpt: Barbosa (sociology, San Francisco State University) provides a global, world-systemic analysis of the problem of deforestation of the Brazilian Amazon rainforest. He shows how changes in global ecopolitics demanding sustainable development, coupled with the onset of democracy in Brazil, substantially altered the battle over the future of Amazonia. He describes deforestation in the region in the context of an expanding frontier of global capitalism, and compares Amazon experiences with those of Costa Rica, Malaysia, and Indonesia.
Download or read book Tropical Rainforest Responses to Climatic Change written by Mark B. Bush and published by Springer Science & Business Media. This book was released on 2007 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide a current overview of the impacts of climate change on tropical forests, to investigate past, present, and future climatic influences on the ecosystems with the highest biodiversity on the planet.Tropical Rainforest Responses to Climatic Change will be the first book to examine how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis onto ecological processes e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of this book that emerges progressively is the interaction between humans, climate and forest ecology. While numerous books have appeared dealing with forest fragmentation and conservation, none have explicitly explored the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, coupled with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging.
Download or read book Global Ecology in Historical Perspective written by Kazunobu Ikeya and published by Springer Nature. This book was released on 2023-03-10 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book primarily examines human-animal and human-plant interactions in Asian forests (Southeast Asia and Japan) and inland waters (China). For comparison, cases from the Americas (whales in the Arctic, sea turtles in the Caribbean, and plants in the Amazon) and Central Asia are also included. The relationship between plants, animals, and humans in Asia is quite unique from a global perspective. For example, "satoyama" in Japan means ecotone area, or the boundary between a village and a forest. There, as the number of inhabitants declines, bears, wild boars, and other animals increasingly ravage crops, sometimes attacking humans as well. By showing the regional nature of human-animal and human-plant interactions in Asia, this book provides for the first time a framework for understanding the world's animal and plant-human relationships. It is assumed that the relationships between humans and animals and plants during this period were diverse, including hunting, taming, semi-domestication, and full domestication. At the same time, for regions outside of Asia, the extent to which these diverse relationships were adapted and how diversity was formed is explained from the perspective of historical ecology. Customers can expect to derive perspectives on the coexistence of human-animal and plant-animal relationships from this book in the near future. The conservation of rare species, diverse habitats, and biodiversity is a central theme in considering the relationship between modern civilization and the global environment. In post-industrial Japan, one focus has been the protection of iconic animals such as storks, crested ibis, dugongs, and sea turtles, while damage to crops and humans by deer, wild boars, monkeys, bears, and other common animals has become an important social issue. How can the world's 7.7 billion-plus people live in harmony with other species? We would like to get some hints on how to solve the problems we are facing.
