This work offers an analysis of the way in which the phenomenon of not in my backyard operates in the United States. The author takes the situation further by offering hope for a heightened public engagement with the pressing environmental issues of the day.
"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"--Provided by publisher.
Debitage, the by-product flakes and chips from stone tool production, is the most abundant artifact type found on prehistoric sites. Archaeologists now recognise its potential in providing information about the kinds of tools produced, the characteristics of the technology that produced them, human mobility patterns and even site function, applying scientific analyses to its study. This volume brings together some of the most recent research on debitage analysis and intepretation, including replication experiments, and offers methodologies for interpreting variability in assemblages at the micro and macro level.
Technology transfer has played an increasingly important role in historic preservation during the latter half of the twentieth century, a situation attested to by the undertaking of an important congressional study in 1986 that assessed the role of federal agencies in the field. In this book leading researchers update the earlier findings and contribute state-of-the-art reviews and evaluations of technological progress in their areas of expertise.
American things, American material culture, and American archaeology are the themes of this book. The authors use goods used or made in America to illuminate issues such as tenancy, racism, sexism, and regional bias. Contributors utilize data about everyday objects - from tin cans and bottles to namebrand items, from fish bones to machinery - to analyze the way American capitalism works. Their cogent analyses take us literally from broken dishes to the international economy. Especially notable chapters examine how an archaeologist formulates questions about exploitation under capitalism, and how the study of artifacts reveals African-American middle class culture and its response to racism.
To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.
