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.
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 report offers a review of what is known about opportunities and risks of biochar systems in developing countries. Its aim is to fill in critical knowledge gaps between the biochar research community and development practicioners on the ground.
Global agriculture is now at the crossroads. The Green Revolution of the last century is losing momentum. Rates of growth in food production are now declining, with land and water resources becoming scarcer, while world population continues to grow. We need to continue to identify and share the knowledge that will support successful and sustainable
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.
Global Change and Forest Soils: Cultivating Stewardship of a Finite Natural Resource, Volume 36, provides a state-of-the-science summary and synthesis of global forest soils that identifies concerns, issues and opportunities for soil adaptation and mitigation as external pressures from global changes arise. Where, how and why some soils are resilient to global change while others are at risk is explored, as are upcoming train wrecks and success stories across boreal, temperate, and tropical forests. Each chapter offers multiple sections written by leading soil scientists who comment on wildfires, climate change and forest harvesting effects, while also introducing examples of current global issues. Readers will find this book to be an integrated, up-to-date assessment on global forest soils. Presents sections on boreal, temperate and tropical soils for a diverse audience Serves as an important reference source for anyone interested in both a big-picture assessment of global soil issues and an in-depth examination of specific environmental topics Provides a unique synthesis of forest soils and their collective ability to respond to global change Offers chapters written by leading soil scientists Prepares readers to meet the daily challenges of drafting multi-resource environmental science and policy documents
Designed as a text not only for students and researchers, but anyone interested in green technology, Advanced Biofuels and Bioproducts offers the reader a vast overview of the state-of-the-art in renewable energies. The typical chapter sets out to explain the fundamentals of a new technology as well as providing its context in the greater field. With contributions from nearly 100 leading researchers across the globe, the text serves as an important and timely look into this rapidly expanding field. The 40 chapters that comprise Advanced Biofuels and Bioproducts are handily organized into the following 8 sections: · Introduction and Brazil's biofuel success · Smokeless biomass pyrolysis for advanced biofuels production and global biochar carbon sequestration · Cellulosic Biofuels · Photobiological production of advanced biofuels with synthetic biology · Lipids-based biodiesels · Life-cycle energy and economics analysis · High-value algal products and biomethane · Electrofuels
Land is fundamental to the human life. The upper layer of land is a non-renewable resource, and source of food. Therefore, land health is essential to long-term food security and to promote sustainable livelihoods. On account of urbanization, industrialization and population growth, land pollution is one of the major issues worldwide. As a result, land pollution is continuing across the world, and has been linked with a wide range of potentially toxic contaminants at rates that deteriorate land quality. Land pollution can result either anthropogenic activities or natural activities. The major contaminants of land pollution are metalloids, petroleum hydrocarbon, radioactive elements, polyaromatic hydrocarbons (PAHs), Pesticide, other organic pollutants, etc. that comes from different types of sources. In urban and peri-urban areas, irrigation of agricultural land with polluted water is also a reason of land pollution. Therefore, land security is an important issue for future sustainability. Its remediation and management are important issue worldwide to protect land quality and functions. Land pollution means degradation of earth's surface. Polluted land comes under the category of degraded land. Hence, the remediation of polluted land is essential for regaining biodiversity and ecosystems services and thereby achieving United Nations-Sustainable Development Goals (UN-SDGs).This fact showed the need to develop research into land remediation. Bio-inspired land remediation has undergone a huge development. Therefore, Biomanagement has a lot of potential to secure upper earth’s surface through the land remediation programs targeted during the United Nations Decade on Ecosystem Restoration (2021-2030). This book explores the remediation of land pollution that includes Phytoremediation, Bioremediation (bacterial remediation and fungal remediation), Vermiremediation, Biochar-based remediation and other Bio-inspired remediation. This book will be a remarkable asset for research scholars, environmentalists, ecological scientist, agriculturist, practitioners, policy makers, entrepreneurs, and other stakeholders alike.
