Rare Earths elements are composed of 15 chemical elements in the periodic table. Scandium and yttrium have similar properties, with mineral assemblages, and are therefore referred alike in the literature. Although abundant in the planet surface, the Rare Earths are not found in concentrated forms, thus making them economically valued as they are so challenging to obtain. Rare Earths Industry: Technological, Economic and Environmental Implications provides an interdisciplinary orientation to the topic of Rare Earths with a focus on technical, scientific, academic, economic, and environmental issues. Part I of book deals with the Rare Earths Reserves and Mining, Part II focuses on Rare Earths Processes and High-Tech Product Development, and Part III deals with Rare Earths Recycling Opportunities and Challenges. The chapters provide updated information and priceless analysis of the theme, and they seek to present the latest techniques, approaches, processes and technologies that can reduce the costs of compliance with environmental concerns in a way it is possible to anticipate and mitigate emerging problems.

This book presents an overview of current renewable energy sources, challenges and future trends. Drawing from their longtime expertise and deep knowledge of the field, the authors present a critic and well-structured perspective on sustainable power sources and technologies, including solar, wind, hydrogen and nuclear, both in large and small scale. Using accessible language they provide rigorous technological reviews and analyze the main issues of practical usage. The book addresses current questions in this area, such as: "Is there enough biomass to make a difference in energy needs? Should biomass be used in Energy Generation?"; "How mature is battery technology? Will it finally become cost effective, and will it make a significant difference this next decade?"; "How big a role will small and modular nuclear power generation play in the coming decades?"; "What will be the influence of national tax policies?". No prior technical knowledge is assumed of the reader. It is, therefore, ideal for professionals and students in all areas of energy and power systems, as well as those involved in energy planning, management and policy.

Written by researchers and practitioners from many different countries, the included papers provide a unique reference of experience and potential solutions to common problems via the application of planning and development strategies, assessment tools and decision making processes.

Sustainable Horticulture: Microbial Inoculants and Stress Interaction gives insights into the applications and formulations of microbial inoculants. In recent years, the optimum yields of horticultural plants largely influenced by rising global temperature, biotic stress (attack of pathogens) and abiotic stresses has created extra pressure for the horticulturalist to meet the need of optimum yield production for the burgeoning global population. However, the challenges of biotic and abiotic stress factors mitigated by traditional physical or chemicals methods include high application cost and adverse impact on quality limit the frequent use, hence the solutions in this book create new avenues for progress. This book covers those challenges and how microbial based bio inoculants are broadly used in horticulture to mitigate the challenges of biotic and abiotic stresses. It provides an important contribution on how to apply efficient beneficial microbes (microbial inoculants) for a sustainable society.

Biodynamic agriculture first originated in central Europe but is now practised in farms, vineyards and gardens all over the world. At the heart of the biodynamic approach are the eight preparations -- Horn manure, Horn silica, Yarrow, Chamomile, Nettle, Oak bark, Dandelion and Valerian -- which are often produced by local biodynamic practitioners using well-established recipes. But as the biodynamic approach expands beyond its European origins, its methods have been increasingly adapted to meet the needs and challenges -- climates, fauna, seasons and regulations -- of different regions around the globe. This fascinating book presents the results of a unique study, carried out by the Agricultural Section at the Goetheanum, Switzerland, into how the biodynamic preparations are used in fifteen countries worldwide, including Egypt, Brazil, New Zealand, India and across Europe. The detailed case studies explore how the preparations are modified to suit their locations, as well as offering an insight into the work of each practitioner and how their understanding has evolved over the years. Contributors include Ueli Hurter, Dr. R. Ingold, Dr. M. Kolar, J. Schoenfelder, Dr. A. Sedlmayr and A. van Leewen. This book is a valuable reference into the production and application of the preparations around the world and an inspiring endorsement of how biodynamic principles hold true in such varied environments.

Dead zones are on the rise... Human activity has caused an increase in uninhabitable, oxygen-poor zones-also known as "dead zones"-in our waters. Oxygen is the third most abundant element in the universe, and it is a necessity for nearly all life on Earth. Yet many rivers, estuaries, coastal waters, and parts of the open ocean lack enough of it. In this book, David L. Kirchman explains the impacts of dead zones and provides an in-depth history of oxygen loss in water. He details the role the agricultural industry plays in water pollution, showcasing how fertilizers contaminate water supplies and kickstart harmful algal blooms in local lakes, reservoirs, and coastal oceans. Algae decomposition requires so much oxygen that levels drop low enough to kill fish, destroy bottom-dwelling biota, reduce biological diversity, and rearrange food webs. We can't undo the damage completely, but we can work together to reduce the size and intensity of dead zones in places like the Gulf of Mexico, Chesapeake Bay, and the Baltic Sea. Not only does Kirchman clearly outline what dead zones mean for humanity, he also supplies ways we can reduce their deadly impact on human and aquatic life. Nutrient pollution in some regions has already begun to decline because of wastewater treatment, buffer zones, cover crops, and precision agriculture. More needs to be done, though, to reduce the harmful impact of existing dead zones and to stop the thousands of new ones from cropping up in our waters. Kirchman provides insight into the ways changing our diet can reduce nutrient pollution while also lowering greenhouse gasses emitted by the agricultural industry. Individuals can do something positive for their health and the world around them. The resulting book allows readers interested in the environment-whether students, policymakers, ecosystem managers, or science buffs-to dive into these deadly zones and discover how they can help mitigate the harmful effects of oxygen-poor waters today.

Cement production is known to be a polluting and energy-intensive industry. Cement plants account for 5 percent of global emissions of carbon dioxide and one of the main causes of global warming. However, cement it is literally the glue of progress. Designing Green Cement Plants provides the tools and techniques for designing new large cement plants that would promote sustainable growth, preserve natural resources to the maximum possible extent and make least possible additions to the Greenhouse Gases that cause global warming. Brief and but authoritative, this title embraces new technologies and methods such as Carbon Capture and Sequestration, as well as methods for harnessing renewable energy sources such as wind and solar. The author also discusses the efficient use of energy and materials through the use recycling. In addition, this book also examines thepossibilities of developing green cement substitutes such as Calera, Caliix, Novacem, Aether and Geopolymer cements.

The promises, dreams and hopes of architects for future cities are now inextricably linked to climate change. Architects, Sustainability and the Climate Emergency: A Political Ecology chronicles how architects have shaped their ideas of the city-and sustainability-as knowledge of the climate emergency has unfolded. Have architects responded to the climate crisis too slowly? Describing a political ecology of architecture, Peter Raisbeck draws on architectural history, theory and practice, and the climate imaginaries of architects themselves. This exploration indicates how architects have viewed the climate emergency and positions architecture alongside the politics of climate and development studies. Raisbeck questions to what degree the traditional agency of architects leads to a political authority isolated from nature, human-environment systems and the nonhuman ecological subjects rapidly approaching tipping points. The fluidity of the climate emergency itself and its unfolding relationship to architectural knowledge suggests that new approaches, agencies and subjectivities are urgently required. As architects struggle to respond to the climate emergency, this book is an important and timely contribution to sustainability, climate and development debates. Architects, Sustainability and the Climate Emergency: A Political Ecology is a necessary provocation of a critical topic.

The degradation of our life-enhancing planet Earth has resulted in climate change, desertification, wild fires, livestock mortality, microbial ecosystem alteration, floods, extreme weather conditions, economic meltdown, poverty, resource conflicts, disease, death, and desperate migration from the most vulnerable regions. Africa, the world`s hottest continent, has deserts and drylands that cover about 60 percent of its land surface area and remains the most vulnerable continent to climate change. At the same time, Africa is the world's second most populous continent and is projected soon to be the most populous. Dr. Popoola's work highlights the uniqueness of Africa and the extent of its vulnerability to global climate change as well as its advantages and limitations in context of current mitigation and adaptation strategies. Africa and Climate Change is an indispensable guide to ensuring global food security, sustainable livelihoods, and ecosystem survival, not only in Africa, but in other less vulnerable continents.

Current social, economic, and environmental challenges presented by the United Nations' Sustainable Development Goals may be partially attained by digitalization and sustainable practices diffusion.
