Book Description
This book deals with the sustainability of agriculture on the Black Earth by drawing on data from long-term field experiments. It emphasises the opportunities for greater food and water security at local and regional levels. The Black Earth, Chernozem in Russian, is the best arable soil in the world and the breadbasket of Europe and North America. It was the focus of scientific study at the very beginnings of soil science in the late 19th century—as a world in itself, created by the roots of the steppe grasses building a water-stable granular structure that holds plentiful water, allows rapid infiltration of rain and snow melt, and free drainage of any surplus. Under the onslaught of industrial farming, Chernozem have undergone profound but largely unnoticed changes with far-reaching consequences—to the point that agriculture on Chernozem is no longer sustainable. The effects of agricultural practices on global warming, the diversion of rainfall away from replenishment of water resources to destructive runoff, and the pollution of streams and groundwater are all pressing issues. Sustainability absolutely requires that these consequences be arrested.

Book Description
“The problem of the Twentieth Century is the problem of the color line.” This infamous formulation is the central idea around which W. E. B. Du Bois crafted what would become the most influential work about race in America: The Souls of Black Folk. Since he penned these words in 1903, the fraught relationship between the races has dominated the country’s policies, economy, and social developments. Published forty years after the Emancipation Proclamation, Du Bois’s radioactive essays addressed an American nation that had still not yet found “peace from its sins.” Today, amid furor over voting rights, mass incarceration, police brutality and extrajudicial killing, the ghosts of white supremacy and ethnonationalism, and the apparent fragility of the equality and desegregation gains of the Civil Rights Movement, Du Bois’s work has proven prophetic, and more urgently necessary than ever. Striking in their psychological precision and political foresight, the fourteen chapters of The Souls of Black Folk move between historical and sociological essays, song and poetry, personal recollection and fiction, laying out the foundational ideas of “double-consciousness”—an inner conflict created by the seemingly irreconcilable “black” and “American” identities—and “the veil,” through which African-Americans must see a spectrum of economic, social, and political opportunities entirely differently from their white counterparts. For anyone interested in understanding race in America, or in the literary lineage that Du Bois generated—from James Baldwin’s The Fire Next Time, to Toni Morrison’s Sula, to Ta-Nehisi Coates’s Between the World and Me—The Souls of Black Folk is essential reading.

Book Description
Soil is the Earth’s living skin. It provides anchorage for roots, holds water long enough for plants to make use of it and the nutrients that sustain life – otherwise the Earth would be as barren as Mars. It is home to myriad micro-organisms and armies of microscopic animals as well as the familiar earthworm that accomplish biochemical transformations from fixing atmospheric nitrogen to recycling wastes; it receives and process all fresh water, provides the foundations for our built environment; and comprises the biggest global carbon store that we know how to manage. This book is about the best soil in the world - the black earth or chernozem: how it is being degraded by farming and how it may be farmed sustainably. Industrialisation of farming has laid bare contradictions between the unforgiving laws of ecology and economics. Soil organic matter is the fuel that powers soil systems and the cement that holds the soil together – and in place – but agriculture is burning it up faster than it is being formed: even the chernozem cannot long survive this treatment. Here is the evidence for this trend and, based on long-term field experiments, ecological principles for sustainable agriculture that can reverse the trend and, at the same time, feed the world. Unlike other volumes in the series, this is not an edited collection of scientific papers. The authors have chosen the classical monograph to be near to the reader from beginning to end - to convey their anxiety about the state of the land and their optimism about the possibility of retrieving the situation by changing the social and political approach to the land so as to provide the necessary incentives for sustainable land use and management.
