The Biochar Handbook

With extensive research, real-world examples, and hands-on applications, this go-to guide offers a comprehensive look at the principles and practices of biochar—and all of its world-changing uses. Like many human discoveries, biochar has likely been invented, lost, and reinvented multiple times. It can be found in the rich terra preta soils of the Amazon and in the ancient “dark earths” dotting Africa, Asia, and Europe. However, biochar isn’t just an archeological curiosity. In The Biochar Handbook, author Kelpie Wilson argues that the simple process of burning organic material in a low-oxygen, low-emission environment could be one of the most powerful tools we have to restore degrad...

Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Amazonia in the Anthropocene

Widespread human alteration of the planet has led many scholars to claim that we have entered a new epoch in geological time: the Anthropocene, an age dominated by humanity. This ethnography is the first to directly engage the Anthropocene, tackling its problems and paradoxes from the vantage point of the world’s largest tropical rainforest. Drawing from extensive ethnographic research, Nicholas Kawa examines how pre-Columbian Amerindians and contemporary rural Amazonians have shaped their environment, describing in vivid detail their use and management of the region’s soils, plants, and forests. At the same time, he highlights the ways in which the Amazonian environment resists human manipulation and control—a vital reminder in this time of perceived human dominance. Written in engaging, accessible prose, Amazonia in the Anthropocene offers an innovative contribution to debates about humanity’s place on the planet, encouraging deeper ecocentric thinking and a more inclusive vision of ecology for the future.

Biochar, a biomass that is burned at very high temperature in the absence of oxygen, has recently become an interesting subject of study. Biochar is highly stable and does not degrade; it possesses physical properties that assist in retention of nutrients in the soil. The use of biochar will undoubtedly have a significant impact not only on soil nutrients but also on soil organism communities and their functions. This book focuses on how the ecology and biology of soil organisms is affected by the addition of biochar to soils. It takes into account direct and indirect effects of biochar addition to soils, on the soil carbon cycle, impact on plant resistance to foliar and soilborne disease, interactions with pathogenic, mycorhizal and saprophytic fungi. The stability of biochar in soil environment is also discussed. Special focus has been put on application of biochar to remediate polluted soils, taking into account possible toxic effects of biochar on soil fauna. This book will be useful to students and researchers in agronomy, biology, ecology, and environmental managers from both academic as well as industrial organizations.

NATIONAL BESTSELLER • A groundbreaking work of science, history, and archaeology that radically alters our understanding of the Americas before the arrival of Columbus in 1492—from “a remarkably engaging writer” (The New York Times Book Review). Contrary to what so many Americans learn in school, the pre-Columbian Indians were not sparsely settled in a pristine wilderness; rather, there were huge numbers of Indians who actively molded and influenced the land around them. The astonishing Aztec capital of Tenochtitlan had running water and immaculately clean streets, and was larger than any contemporary European city. Mexican cultures created corn in a specialized breeding process that it has been called man’s first feat of genetic engineering. Indeed, Indians were not living lightly on the land but were landscaping and manipulating their world in ways that we are only now beginning to understand. Challenging and surprising, this a transformative new look at a rich and fascinating world we only thought we knew.

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 natur...
