Amazonian Dark Earths Wim Sombroek S Vision

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.

Agricultural and Environmental Applications of Biochar: Advances and Barriers: Over the past decade, biochar has been intensively studied by agricultural and environmental scientists and applied as a soil quality enhancer and environmental ameliorator in various trials worldwide. This book, with 21 chapters by 57 accomplished international researchers, reports on the recent advances of biochar research and the global status of biochar application. Scientific findings, uncertainties, and barriers to practice of biochar amendment for sustaining soil fertility, improving crop production, promoting animal performance, remediating water and land, and mitigating greenhouse gas emissions are synthesized. The book presents a whole picture of biochar in its production, characterization, application, and development. Agricultural and Environmental Applications of Biochar: Advances and Barrier highlights the mechanisms and processes of biochar amendment for achieving stunning agricultural and environmental benefits. Composition and characteristics of biochar, its interactions with contaminants and soil constituents, and its transformation in the environment are illustrated to enlighten the achievements of biochar amendment in improving soil physical, chemical, and biological quality and animal health, reducing soil greenhouse gas emissions, and decontaminating stormwater and mine sites. Additional emphasis is given to the pyrogenic carbon in Terra Preta soils and Japanese Andosols, the pyrolysis technology for converting agricultural byproducts to biochar, and the existing economic and technical barriers to wide application of biochar in Australia, China, New Zealand, North America, and Europe. Readers will appreciate the comprehensive review on the up-to-date biochar research and application and gain critical guidance in best biochar generation and utilization.

Distinct practices of eating are at the heart of many of the world's faith traditions -- from the Christian Eucharist to Muslim customs of fasting during Ramadan to the vegetarianism and asceticism practiced by some followers of Hinduism and Buddhism. What we eat, how we eat, and whom we eat with can express our core values and religious devotion more clearly than verbal piety. In this wide-ranging collection, eminent scholars, theologians, activists, and lay farmers illuminate how religious beliefs influence and are influenced by the values and practices of sustainable agriculture. Together, they analyze a multitude of agricultural practices for their contributions to healthy, ethical living and environmental justice. Throughout, the contributors address current critical issues, including global trade agreements, indigenous rights to land and seed, and the effects of postcolonialism on farming and industry. Covering indigenous, Buddhist, Hindu, Christian, Muslim, and Jewish perspectives, this groundbreaking volume makes a significant contribution to the study of ethics and agriculture.

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.

Conservation and development share an intertwined history dating back to at least the 1700s. But what are the prospects for reconciling the two, and how far have we come with this project? This book explores these questions through a detailed consideration of the past, present and future of the relationship between conservation and development. Bringing to bear conceptual resources from political ecology, social-ecological systems thinking and science and technology studies, Conservation and Development sets this relationship against the background of the political and economic processes implicated in environmental degradation and poverty alike. Whilst recognising that the need for reconciling conservation and development processes remains as compelling as ever, it demonstrates why trade-offs are more frequently encountered in practice than synergies. It also flags alternative visions for conservation and development obscured or ignored by current framings and priorities. Bringing together policy and theory, Conservation and Development is an essential resource for undergraduate and postgraduate students and a useful reference for researchers in related fields. Each chapter contains a reading guide with discussion questions. The text is enlivened by a number of new case studies from around the world. A must-read for anyone interested in understanding the history, current state, and projections for future shifts in the relationship between conservation and development.

A fascinating description of how utilizing the biochar embedded in terra preta, the recently rediscovered sacred soil of the pre-Columbian peoples of the Amazon rainforest, can cut our dependency on petrochemicals, restore the health of our soils, remove carbon from our overheating atmosphere, and restore the planet to pre-industrial levels of atmospheric carbon by 2050. The authors show that the rediscovery of terra preta is an opportunity to move beyond the West’s tradition of plunder and genocide of the native civilizations of the Americas by offering an invitation to embrace the deeper mystery of the indigenous methods of inquiry and to participate in an animate cosmos that gave rise to such a powerful soil technology. Sacred Soil, in recognizing the need for biocultural regeneration, takes a multi-disciplinary approach to the phenomenon of biochar soils, utilizing mythopoeic, historical, anthropological, and scientific perspectives to embrace the deep past, the vexed present, and the prospectus for our future. Coming at this crucial juncture in human history, the potential resting in biochar is also an open doorway into the indigenous ways of knowing that enabled the pre-Columbian Amazonian high civilizations to support a population of millions while leaving their lands more fertile than when they arose.
