"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.

From one of our most important scholars and civil rights activist icon, a powerful study of the women’s liberation movement and the tangled knot of oppression facing Black women. “Angela Davis is herself a woman of undeniable courage. She should be heard.”—The New York Times Angela Davis provides a powerful history of the social and political influence of whiteness and elitism in feminism, from abolitionist days to the present, and demonstrates how the racist and classist biases of its leaders inevitably hampered any collective ambitions. While Black women were aided by some activists like Sarah and Angelina Grimke and the suffrage cause found unwavering support in Frederick Douglass, many women played on the fears of white supremacists for political gain rather than take an intersectional approach to liberation. Here, Davis not only contextualizes the legacy and pitfalls of civil and women’s rights activists, but also discusses Communist women, the murder of Emmitt Till, and Margaret Sanger’s racism. Davis shows readers how the inequalities between Black and white women influence the contemporary issues of rape, reproductive freedom, housework and child care in this bold and indispensable work.
