Veld is a natural resource vital to our survival on earth. About 80% of our beautiful country consists of veld. Most of this area is used for livestock and game ranching as well as for biodiversity conservation and recreation. Good veld management is needed to prevent land degradation and to ensure sustainable food production and biodiversity conservation. But good veld management relies on a good knowledge of ecological principles and veld management practices, something many land users did not have the privilege to acquire. This book aims to provide the necessary knowledge to assist land users to effectively manage the land under their care, a huge responsibility indeed.

Environmental Materials and Waste: Resource Recovery and Pollution Prevention contains the latest information on environmental sustainability as a wide variety of natural resources are increasingly being exploited to meet the demands of a worldwide growing population and economy. These raw materials cannot, or can only partially, be substituted by renewable resources within the next few decades. As such, the efficient recovery and processing of mineral and energy resources, as well as recycling such resources, is now of significant importance. The book takes a multidisciplinary approach to fully realize the number of by-products which can be remanufactured, providing the foundation needed across disciplines to tackle this issue. As awareness and opportunities to recover valuable resources from process and bleed streams is gaining interest, sustainable recovery of environmental materials, including wastewater, offers tremendous opportunity to combine profitable and sustainable production.

Plants are silent, still, or move slowly; we do not have the sense that they accompany us, or even perceive us. But is there something that plants are telling us? Is there something about how they live and connect, how they relate to the world and other plants that can teach us about ecological thinking, about ethics and politics? Grounded in Thoreau's ecology and in contemporary plant studies, Dispersion: Thoreau and Vegetal Thought offers answers to those questions by pondering such concepts as co-dependence, the continuity of life forms, relationality, cohabitation, porousness, fragility, the openness of beings to incessant modification by other beings and phenomena, patience, waiting, slowness and receptivity.

Volcanic Ash: Hazard Observation presents an introduction followed by four sections, each on a separate topic and each containing chapters from an internationally renowned pool of authors. The introduction provides a volcanological context for ash generation that sets the stage for the development and interpretation of techniques presented in subsequent sections. The book begins with an examination of the methods to characterize ash deposits on the ground, as ash deposits on the ground have generally experienced some atmospheric transport. This section will also cover basic information on ash morphology, density, and refractive index, all parameters required to understand and analyze assumptions made for both in situ measurements and remote sensing ash inversion techniques. Sections two, three, and four focus on methods for observing volcanic ash in the atmosphere using ground-based, airborne, and spaceborne instruments respectively. Throughout the book, the editors showcase not only the interdisciplinary nature of the volcanic ash problem, but also the challenges and rewards of interdisciplinary endeavors. Additionally, by bringing together a broad perspective on volcanic ash studies, the book not only ties together ground-, air-, academic, and applied approaches to the volcanic ash problem, but also engages with other scientific communities interested in particulate transport.

With such a wide range of social and economic uses, energy has become essential to global infrastructure and operations, regardless of economic or environmental cost. Renewable energy sources, where energy is obtained from natural sources such as the sun and wind, currently stand as important alternatives to fossil fuels. Yet their comparatively high installation costs continue to deter investors and further propel the planet towards catastrophic climate change. Conscious of these complexities, Renewable Energy Investments for Sustainable Business Projects identifies multiple solutions for improving the appeal of renewable energy projects. Breaking down myths about their viability and practicality, Hasan Dinçer and Serhat Yüksel take a variety of issues into consideration, including finance, competition, risk management, customer relations, technological factors and learning and growth to formulate a practical rather than theoretical examination of renewable energies and their potential. From tax advantages to hydrogen sourcing, Renewable Energy Investments for Sustainable Business Projects explores a variety of the latest practices and technological developments surrounding renewable energy, offering practical insight and tangible advice to academics and researchers in environmental management.

On Human Nature: Biology, Psychology, Ethics, Politics, and Religion covers the present state of knowledge on human diversity and its adaptative significance through a broad and eclectic selection of representative chapters. This transdisciplinary work brings together specialists from various fields who rarely interact, including geneticists, evolutionists, physicians, ethologists, psychoanalysts, anthropologists, sociologists, theologians, historians, linguists, and philosophers. Genomic diversity is covered in several chapters dealing with biology, including the differences in men and apes and the genetic diversity of mankind. Top specialists, known for their open mind and broad knowledge have been carefully selected to cover each topic. The book is therefore at the crossroads between biology and human sciences, going beyond classical science in the Popperian sense. The book is accessible not only to specialists, but also to students, professors, and the educated public. Glossaries of specialized terms and general public references help nonspecialists understand complex notions, with contributions avoiding technical jargon.

This book dispels common myths about electricity and electricity policy and reveals how government policies manipulate energy markets, create hidden costs, and may inflict a net harm on the American people and the environment. Climate change, energy generation and use, and environmental degradation are among the most salient—and controversial—political issues today. Our country's energy future will be determined by the policymakers who enact laws that favor certain kinds of energy production while discouraging others as much as by the energy-production companies or the scientists working to reduce the environmental impact of all energy production. The Reality of American Energy: The Hidden Costs of Electricity provides rare insights into the politics and economics surrounding electricity in the United States. It identifies the economic, physical, and environmental implications of distorting energy markets to limit the use of fossil fuels while increasing renewable energy production and explains how these unseen effects of favoring renewable energy may be counterproductive to the economic interests of American citizens and to the protection of the environment. The first two chapters of the book introduce the subject of electricity policy in the United States and to enable readers to understand why policymakers do what they do. The remainder of the book examines the realities of the major electricity sources in the United States: coal, natural gas, nuclear, hydrodynamic, wind, biomass, solar, and geothermal. Each of these types of energy sources is analyzed in a dedicated chapter that explains how the electricity source works and identifies how politics and public policy shape the economic and environmental impacts associated with them.

Solid and Hazardous Waste Management: Science and Engineering presents the latest on the rapid increase in volume and types of solid and hazardous wastes that have resulted from economic growth, urbanization, and industrialization and how they have challenged national and local governments to ensure effective and sustainable management of these waste products.
