Book excerpt: 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.

Book excerpt: 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.

Book Synopsis The Brazilian Amazon by : Joana Bezerra

Download or read book The Brazilian Amazon written by Joana Bezerra. This book was released on 2015-08-25. 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.

Book Synopsis Agroecology, Ecosystems, and Sustainability by : Noureddine Benkeblia

Download or read book Agroecology, Ecosystems, and Sustainability written by Noureddine Benkeblia. This book was released on 2014-11-20. Available in PDF, EPUB and Kindle. Book excerpt: 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.
