Amazonian soils are almost universally thought of as extremely forbidding. 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.

This book reconstructs the world of eighteenth-century Amazonia to argue that indigenous mobility did not undermine settlement or community. In doing so, it revises longstanding views of native Amazonians as perpetual wanderers, lacking attachment to place and likely to flee at the slightest provocation. Instead, native Amazonians used traditional as well as new, colonial forms of spatial mobility to build enduring communities under the constraints of Portuguese colonialism. Canoeing and trekking through the interior to collect forest products or to contact independent native groups, Indians expanded their social networks, found economic opportunities, and brought new people and resources back to the colonial villages. When they were not participating in these state-sponsored expeditions, many Indians migrated between colonial settlements, seeking to be incorporated as productive members of their chosen communities. Drawing on largely untapped village-level sources, the book shows that mobile people remained attached to their home communities and committed to the preservation of their lands and assets. This argument still matters today, and not just to scholars, as rural communities in the Brazilian Amazon find themselves threatened by powerful outsiders who argue that their mobility invalidates their claims to territory.

The legendary El Dorado—the city of gold—remains a mere legend, but astonishing new discoveries are revealing a major civilization in ancient Amazonia that was more complex than anyone previously dreamed. Scholars have long insisted that the Amazonian ecosystem placed severe limits on the size and complexity of its ancient cultures, but leading researcher Denise Schaan reverses that view, synthesizing exciting new evidence of large-scale land and resource management to tell a new history of indigenous Amazonia. Schaan also engages fundamental debates about the development of social complexity and the importance of ancient Amazonia from a global perspective. This innovative, interdisciplinary book is a major contribution to the study of human-environment relations, social complexity, and past and present indigenous societies.

We hear a lot about how agriculture affects climate change and other environmental issues, but we hear little about how these issues affect agriculture. When we look at both sides of the issues, we can develop better solutions for sustainable agriculture without adversely affecting the environment. Agroecology, Ecosystems, and Sustainability explores a modern vision of ecology and agricultural systems, so that crop production can be sustainably developed without further environmental degradation. With contributions from experts from more than 20 countries, the book describes how to make the transition to modern agroecology to help the environment. It examines the global availability of natural resources and how agroecology could allow the world population to reach the goal of global sustainable ecological, agricultural, and food production systems. The book discusses important principles that regulate agroecological systems, including crop production, soil management, and environment preservation. Making the link between theory and practices, the book includes examples of agroecology such as an interdisciplinary framework for the management of integrated production and conservation landscapes and the use of mechanized rain-fed farming and its ecological impact on drylands. An examination of how ecology and agriculture can be allied to ensure food production and security without threatening our environment, the text shows you how natural resources can be used in a manner to create a "symbiosis" to preserve ecological systems and develop agriculture.

The importance to preserve soil and water have is increasingly recognized. Agricultural practices and ecological trends both affect and are affected by soil physical properties. The more frequency of natural disasters, as landslides and thunderstorms addresses the importance to integrate soil characteristics in predictive models. Soil physics research has grown considerably specially in the use of innovative sensors, soil databases, and modeling techniques have been introduced into soil water relationship and environmental monitoring. Those advances are thoroughly dispersed in articles and conference proceedings In this volume, the authors will bring together the effectiveness of many new field and lab sensors and examine the current state-of-the-art in modeling and data analysis. It also includes innovative approaches and case studies in tropical soils. Future directions in soil physics research are given by key researchers in this discipline.
