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.
Biochar is the carbon-rich organic matter that remains after heating biomass under minimization of oxygen during a process called pyrolysis. Its relevance to deforestation, agricultural resilience, and energy production, particularly in developing countries, makes it an important issue. This report offers a review of what is known about opportunities and risks of biochar systems. Its aim is to provide a state of the art overview of current knowledge regarding biochar science. In that sense the report also offers a reconciling view on different scientific opinions about biochar providing an overall account that shows the various perspectives of its science and application. This includes soil and agricultural impacts of biochar, climate change impacts, social impacts, and competing uses of biomass. The report aims to contextualize the current scientific knowledge in order to put it at use to address the development- climate change nexus, including social and environmental sustainability. The report is organized as follows: chapter one offers some introductory comments and notes the increasing interest in biochar both from a scientific as well as from a practitioner's point of view; chapter two gives further background on biochar, describing its characteristics and outlining the way in which biochar systems function. Chapter three then considers the opportunities and risks of biochar systems, chapter four presents a typology of biochar systems emerging in practice, particularly in the developing world. New, International Organization for Standardization (ISO) 14040-based life-cycle assessments of the net climate change impact and the net economic profitability of three biochar systems with data collected from relatively advanced biochar projects were conducted for this report and are presented in chapter five, providing a novel understanding of the full life-cycle impacts of these known biochar systems. Chapter six investigates various aspects of technology adoption, including barriers to implementing promising systems, focusing on economics, carbon market access, and sociocultural barriers. Finally, the status of knowledge regarding biochar systems is interpreted in chapter seven to determine potential implications for future involvement in biochar research, policy, and project formulation.

Climate change is one of the major challenges of modern times. Its impacts are manifold and vary from sea level rise (especially relevant to those living in coastal areas), to the increased frequency of extreme events such as cyclones and storm surges, which not only poses problems to property and infrastructure, but also to human health. Climate change is also associated with damages to the physical and natural environment, as well as to biodiversity. According to the 5th Assessment Report produced by the Inter-Governmental Panel on Climate Change (IPCC), many geographical regions across the world are moderately or highly vulnerable to climate change, whose impacts may be further exacerbated by other human-induced pressures. The above state of affairs illustrates the need for a better and more holistic understanding of how climate change affects countries and regions on the one hand, but also on how the many problems it causes may be managed on the other, vis-a-vis a better ability to adapt. There is also a perceived need to showcase successful examples of how to duly address and manage the many social, economic and political problems posed by climate change around the world, in order to replicate and even upscale the successful ones. It is against this background that the Handbook of Climate Change Management has been produced. It contains papers prepared by scholars, social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects, and working with communities across all geographical regions. The Handbook focuses on "Research, Leadership, Transformation," meaning that it serves the purpose of showcasing the role these key areas play in respect of applied research, field projects and best practices to foster climate change adaptation worldwide.
The bioeconomy concept aims to add sustainability to the production, transformation, and trade of biological goods. Though implemented around the world, the development of national bioeconomies is uneven, especially in the global South, where major challenges exist in Sub-Saharan Africa. In this context, the international BiomassWeb project aimed to underpin the bioeconomy concept by applying the value web approach, which seeks to uncover complex interlinked value webs instead of linear value chains. The project also aimed to develop intervention options to strengthen and optimize the synergies and trade-offs among different value chains. The Special Issue “Advances in Food and Non-Food Biomass Production, Processing and Use in Sub-Saharan Africa: Toward a Basis for a Regional Bioeconomy" compiles 23 articles produced in this framework. The articles are grouped in four sections: the value web approach; the production side; processing, transformation and trade; and global views.
This book provides the technological insight on biorefinery and nanoremediation and provides comprehensive reviews on applications of Biochar for environmental sustainability. Critical review on biosurfectants in food applications as well as sustainable agricultural practices has also been provided in this book. It also highlights the microbial-omics and microRNAs for protecting ecotoxicity. Overall, this book provides critical as well as comprehensive chapters on wastewater treatment using different technologies.
Most, if not all of the global biogeochemical cycles on the earth have been broken or are at dangerous tipping points. These broken cycles have expressed themselves in various forms as soil degradation and depletion, ocean acidification, global warming and climate change. The best proposal for an organic solution to fixing the myriad broken cycles is a deliberate investment in solutions that first acknowledge the historic roles played by both the subjugated peoples, and the economic beneficiaries of the environmental exploitations of the past. Ever since Europeans made contact with the West, a series of global circumstances including the genocide of the indigenous people of the Americas, the enslavement and global subjugation of Africans, and the emergence of Western concepts of trade dominance and capitalism, have led to deleterious impacts on the global biogeochemical cycles. Addressing the broken biogeochemical cycles should be done with a clear understanding that it was not only human subjects which were subjugated, but also land, water, and air. These three global stores must be replenished from the ideological position that poverty is not simply the absence of money, but is also the lack of access to non-polluting energy sources, to clean air devoid of runaway greenhouse gasses, and to local conditions devoid of climate change instabilities. With this in mind, the global powerbrokers can enter into a new deal with developing nations, shifting the paradigm toward a new ecological approach that rewards good behavior and sets new standards of worldwide relations based on ecologic inclusivity rather than the exclusive economic arrangements currently in order. Harnessing a forward thinking approach to analyzing the current global environmental crisis, this book will be of great interest to students and scholars of sustainable development, political ecology, sustainable agriculture, climate change and environmental justice.
Biochar is a carbon-rich material produced from the pyrolysis of organic materials from agricultural and forestry biomass at a relatively low temperature in the absence of oxygen. As such, it has potential for solving many agricultural and environmental problems.This book is divided into five sections: “Introduction,” “Production and Legislation of Biochar,” “Applications of Biochar for Soil Fertility Improvement,” “Role of Biochar for Soil Remediation and Ameliorating Salinity Effects” and “Applications of Biochar for Water Treatment.” Chapters address topics such as the pros and cons of biochar, its production, and its role in remediating and treating contaminated soils and water.
