Desertification and land degradation are complex phenomena, and we need to understand their causes, consequences, and means to mitigate and combat their impact. Therefore, this book aims to explain the concept and characteristics of drylands, desert and desertification, land degradation, wastelands, and the concept of ecosystem services. It also discusses various types of processes of land degradations, their characteristics, physics and indicators along with mapping, monitoring and assessment of methods involved. Concept of Ocean Biological Deserts is discussed along with international and regional efforts towards combating land degradation and desertification. Key Features: • Provides all the aspect of desertification and land degradation at one place • Includes comprehensive methods to monitor different desertification/land degradation processes • Comprehensive overview of the mapping, monitoring and modelling techniques • Role of space borne data in identifying, monitoring and combating desertification is evaluated and reported with real case studies • Explains the concept of ocean biological deserts, their characteristics and mapping

From the best-selling, award-winning author of 1491 and 1493--an incisive portrait of the two little-known twentieth-century scientists, Norman Borlaug and William Vogt, whose diametrically opposed views shaped our ideas about the environment, laying the groundwork for how people in the twenty-first century will choose to live in tomorrow's world. In forty years, Earth's population will reach ten billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.

Once patronized primarily by the counterculture and the health food establishment, the organic food industry today is a multi-billion-dollar business driven by ever-growing consumer demand for safe food and greater public awareness of ecological issues. Assumed by many to be a recent phenomenon, that industry owes much to agricultural innovations that go back to the Dust Bowl era. This book explores the roots and branches of alternative agricultural ideas in twentieth-century America, showing how ecological thought has challenged and changed agricultural theory, practice, and policy from the 1930s to the present. It introduces us to the people and institutions who forged alternatives to industrialized agriculture through a deep concern for the enduring fertility of the soil, a passionate commitment to human health, and a strong advocacy of economic justice for farmers. Randal Beeman and James Pritchard show that agricultural issues were central to the rise of the environmental movement in the United States. As family farms failed during the Depression, a new kind of agriculture was championed based on the holistic approach taught by the emerging science of ecology. Ecology influenced the "permanent agriculture" movement that advocated such radical concepts as long-term land use planning, comprehensive soil conservation, and organic farming. Then in the 1970s, "sustainable agriculture" combined many of these ideas with new concerns about misguided technology and an over-consumptive culture to preach a more sensible approach to farming. In chronicling the overlooked history of alternative agriculture, A Green and Permanent Land records the significant contributions of individuals like Rex Tugwell, Hugh Bennett, Louis Bromfield, Edward Faulkner, Russell and Kate Lord, Scott and Helen Nearing, Robert Rodale, Wes Jackson, and groups like Friends of the Land and the Practical Farmers of Iowa. And by demonstrating how agriculture also remains central to the public interest—especially in the face of climatic crises, genetically altered crops, and questionable uses of pesticides—this book puts these issues in historical perspective and offers readers considerable food for thought.
