Available in PDF, EPUB and Kindle. Book excerpt: The extraordinary fertility of manmade Terra Preta soils in the Brazilian Amazon provided the incentive to study the effects of soil charcoal amendments on soil fertility, nutrient cycling, and soil biology. The existence of Terra Preta suggests that tropical soils, which are notorious for being infertile, can be greatly improved. The agricultural produces charcoal out of fallow vegetation instead of converting it to carbon dioxide through burning. Slash and char improves soil quality by transferring organic carbon into recalcitrant soil organic matter pools. This newly described agricultural practice has important implications for the earth's carbon budget and sustainability in tropical agriculture.

However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed ‘terra preta’ or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future sustainability of food production in tropical environments. The late Dutch soil scientist Wim Sombroek (1934-2003) was instrumental in bringing the significance of these soils to the attention of the world over four decades ago. Wim saw not only the possibilities of improving the lives of small holders throughout the world with simple carbon based soil technologies, but was an early proponent of the positive synergies also achieved in regards to carbon sequestration and global climatic change abatement. Wim’s vision was to form a multidisciplinary group whose members maintained the ideal of open collaboration toward the attainment of shared goals. Always encouraged and often shaped by Wim, this free association of international scholars termed the “Terra Preta Nova” Group came together in 2001 and has flourished. This effort has been defined by enormous productivity. Wim who is never far from any of our minds and hearts, would have loved to share the great experience of seeing the fruits of his vision as demonstrated in this volume.

Book excerpt: Accessibly written by a team of international authors, the Encyclopedia of Environmental Change provides a gateway to the complex facts, concepts, techniques, methodology and philosophy of environmental change. This three-volume set illustrates and examines topics within this dynamic and rapidly changing interdisciplinary field. The encyclopedia includes all of the following aspects of environmental change: Diverse evidence of environmental change, including climate change and changes on land and in the oceans Underlying natural and anthropogenic causes and mechanisms Wide-ranging local, regional and global impacts from the polar regions to the tropics Responses of geo-ecosystems and human-environmental systems in the face of past, present and future environmental change Approaches, methodologies and techniques used for reconstructing, dating, monitoring, modelling, projecting and predicting change Social, economic and political dimensions of environmental issues, environmental conservation and management and environmental policy Over 4,000 entries explore the following key themes and more: Conservation Demographic change Environmental management Environmental policy Environmental security Food security Glaciation Green Revolution Human impact on environment Industrialization Landuse change Military impacts on environment Mining and mining impacts Nuclear energy Pollution Renewable resources Solar energy Sustainability Tourism Trade Water resources Water security Wildlife conservation The comprehensive coverage of terminology includes layers of entries ranging from one-line definitions to short essays, making this an invaluable companion for any student of physical geography, environmental geography or environmental sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Deforestation and forest degradation represent a significant fraction of the annual worldwide human-induced emission of greenhouse gases to the atmosphere, the main source of biodiversity losses and the destruction of millions of people's homes. Despite local/regional causes, its consequences are global. This book provides a general view about deforestation dynamics around the world, incorporating analyses of its causes, impacts and actions to prevent it. Its 17 Chapters, organized in three sections, refer to deforestation impacts on climate, soil, biodiversity and human population, but also describe several initiatives to prevent it. A special emphasis is given to different remote-sensing and mapping techniques that could be used as a source for decision-makers and society to promote forest conservation and control deforestation.

Available in PDF, EPUB and Kindle. Book excerpt: The impacts of climate change on human societies, and the roles those societies themselves play in altering their environments, appear in headlines more and more as concern over modern global climate change intensifies. Increasingly, archaeologists and paleoenvironmental scientists are looking to evidence from the human past to shed light on the processes which link environmental and cultural change. Establishing clear contemporaneity and correlation, and then moving beyond correlation to causation, remains as much a theoretical task as a methodological one. This book addresses this challenge by exploring new approaches to human-environment dynamics and confronting the key task of constructing arguments that can link the two in concrete and detailed ways. The contributors include researchers working in a wide variety of regions and time periods, including Mesoamerica, Mongolia, East Africa, the Amazon Basin, and the Island Pacific, among others. Using methodological vignettes from their own research, the contributors explore diverse approaches to human-environment dynamics, illustrating the manifold nature of the subject and suggesting a wide variety of strategies for approaching it. This book will be of interest to researchers and scholars in Archaeology, Paleoenvironmental Science, Ecology, and Geology.
