Emerging Patterns in Proterozoic Lipid Biomarker Records (Elements in Geochemical Tracers in Earth System Science)
by Gordon D. Love J. Alex ZumbergeDiverse and abundant lipid biomarker assemblages have been reported from a variety of Proterozoic marine environments from the careful analysis of well-preserved rocks and oils. These molecular biosignatures have provided unique insights into the communities and the environmental conditions which characterized the Proterozoic marine biosphere. We summarize some of the major temporal patterns evident in Proterozoic lipid biomarkers found to date, whilst emphasizing the scale of local heterogeneity found within Neoproterozoic oceans from region to region, and their relationship with the evolving ecological, climatic and ocean/atmospheric redox conditions. Short commentaries on a selection of papers published from the last 15 years of biomarker literature are given. The focus here is on key studies, highlighted for further reading, which have helped to better constrain the timing of the ecological expansion of eukaryotes in Proterozoic oceans or which have impacted on our knowledge of the biological sources of Proterozoic biomarkers.
Emerging Pollutants: Protecting Water Quality for the Health of People and the Environment (Advances in Water Security)
by Ali Fares Gabriel Eckstein Sarantuyaa ZandaryaaThis open access book focuses on the importance of reducing pollution and protecting water resources for the health of people and the environment. Water is vital for life on Earth. The quality of the world's freshwater resources is deteriorating due to the rise in pollution levels, which puts the health of people and the environment at risk. Emerging pollutants, a new class called Contaminants of Emerging Concern, pose a global water quality challenge. The identification and implementation of appropriate regulatory, monitoring, prevention, and control measures are hindered by limited scientific understanding and knowledge about sources and pathways of emerging pollutants, their behaviour and fate in the environment, and potential human and ecosystem health risks. The book presents selected contributions to the UNESCO-IWRA Online Conference “Emerging Pollutants: Protecting Water Quality for the Health of People and the Environment,” held on 17–19 January 2023. It offers an extensive overview of current research findings on emerging pollutants in aquatic ecosystems, groundwater contamination, wastewater management and reuse, circular economy approaches to pollutant lifecycle management, and the prioritization of emerging pollutants in the hydro-cycle. Based on scientific evidence and policy-relevant research findings, the book’s concluding chapter highlights research and policy gaps, offering recommendations for strategic and practical ways to manage emerging pollutants towards sustainable water management in the face of global changes and evolving environmental threats. This book is a scientific output in the framework of UNESCO Intergovernmental Hydrological Programme’s Ninth Phase “Science for a Water-Secure World in a Changing Environment” (IHP-IX, 2022-2029) and UNESCO-IHP’s International Initiative on Water Quality (IIWQ) in collaboration with the International Water Resources Association (IWRA).
Emerging Research in Alternative Crops (Environment & Policy #58)
by Ragab Ragab Redouane Choukr-Allah Abdelaziz HirichThis book provides case studies on cultivating alternative crops and presents new cropping systems in many regions of the world. It focusses on new emerging research topics aiming to study all aspects of adaptation under several stresses including agricultural, environmental, biological and socioeconomic issues. The book also provides operational and practical solutions for scientists, producers, technology developers and managers to succeed the cultivation of new alternative crops and, consequently, to achieve food security.Many regions in the world are suffering from water scarcity, soil and water salinization and climate change. These conditions make it difficult to achieve food security by cultivating conventional crops. A renaissance of interest for producing alternative crops under water scarcity and water salinization has been, therefore, implemented primarily among small-scale producers, researchers and academics.The use of alternative crops (quinoa, amaranth, legume crops, halophytes, …etc.) may provide some environmental benefits such as valorization of salt-affected soils, reduced pesticide application, enhanced soil and water quality and promotion of wildlife diversity. This also may provide some economic benefits such as providing the opportunity for producers to take advantage of new markets and premium prices, spreading the economic risk and strengthening local economies and communities. Furthermore, alternative crops are often rich in proteins and minerals, and even some of them are Gluten free (quinoa). This reflects their importance to achieve food security in quantity and quality scale. The year 2013 was exceptional for alternative crops as it was the international year of quinoa celebrated by Food and Agriculture Organization (FAO). This reflects the importance of research conducted on quinoa and other alternative crops in many regions of the world.

Emerging Viruses in Latin America: Contemporary Virology (The Latin American Studies Book Series)
by Flor H. Pujol Alberto E. Paniz-MondolfiLatin America has extensive microbial diversity and is endemic for a wide array of infectious agents including dengue, chikungunya, malaria and tuberculosis. In 2014, the WHO cited 93 public health events of potential international concern in the Latin American region where over half (47 events) were caused specifically by chikungunya and other zoonotic pathogens, causing geographically widespread impact affecting 27 countries and territories. Arena, alpha and flaviviruses are RNA viruses, many of which are endemic in South America, are diverse in nature, and can adapt easily to new hosts, creating zoonotic threats. Since more than 70% of emerging diseases are caused by zoonotic agents, it is of great importance to enhance the capacity for detection and diagnosis in the areas where they are most likely to emerge. COVID-19 provided an opportunity to reinforce public health capacities, improve reporting transparency, and enhance regional coordination. Limited but consistent research has been carried out in the region to address the viral threats that account for a significant portion of health concerns. This book describes relevant examples of these achievements and discusses ongoing limitations in the region.
Emerging Workforce Trends in the U.S. Energy and Mining Industries: A Call to Action
by Committee on Earth ResourcesEnergy and mineral resources are essential for the nation's fundamental functions, its economy, and security. Nonfuel minerals are essential for the existence and operations of products that are used by people every day and are provided by various sectors of the mining industry. Energy in the United States is provided from a variety of resources including fossil fuels, and renewable and nuclear energy, all with established commercial industry bases. The United States is the largest electric power producer in the world. The overall value added to the U. S. gross domestic product (GDP) in 2011 by major industries that consumed processed nonfuel mineral materials was $2. 2 trillion. Recognizing the importance of understanding the state of the energy and mining workforce in the United States to assure a trained and skilled workforce of sufficient size for the future, the Department of Energy's (DOE's) National Energy technology Laboratory (NETL) contracted with the National Research Council (NRC) to perform a study of the emerging workforce trends in the U.

Emerging and Innovative Arsenic Removal Technologies for a Sustainable Future (Water Science and Technology Library #131)
by Akhilesh Kumar Yadav Saba ShirinThis book presents an overview of the techniques available today to remove arsenic contamination, pollutants, and species from water. Traditionally applied techniques for removal of arsenic pollutants/species, including oxidation, coagulation-flocculation, and membrane techniques. Furthermore, recent progress has been made on the utility of various nanoparticles for the extraction of contaminated water. Arsenic contamination affects the quality of water resources worldwide as a result of human activities (pesticides and other uses). Due to the insufficiency of water treatment facilities in developing countries, oral exposure to chemical toxicants through drinking water is a health threat. Arsenic is a mobile element with a crustal abundance of 1.8 mg kg-1 and can travel in different components of the environment, including air, soil, and water before entering into its ultimate sink, that is, bottom sediments and sea. Arsenic may enter groundwater from both geogenic and anthropogenic sources and primarily exists in inorganic form as oxy-anions. Groundwater is relatively more vulnerable to arsenic contamination from geothermal inputs, including the weathering and dissolution of arsenic-bearing rocks and minerals. Arsenic mobility is enhanced in subsurface anoxic conditions, making groundwater more vulnerable to arsenic contamination. Ingestion of groundwater-laden arsenic may cause carcinogenic and non-carcinogenic health ailments. Chronic oral exposure ≤ 50 µg L-1 of arsenic can cause skin lesions, skin cancer, melanosis, hyperkeratosis, hypertension, gangrene, cardiovascular problems, black foot disease, neuropathy, peripheral vascular disease, restrictive lung disease, bladder cancer, lung cancer etc. Hence, specific water treatment processes are required to meet anticipated more severe water quality standards. A better understanding of currently available processes is necessary to develop economical, efficient and effective methods for arsenic removal. Arsenic can be coated, adsorbed using a wide range of mineral and organic or can be directly rejected by membrane processes such as reverse osmosis and nanofiltration. The recent development of submerged hybrid membrane systems, such as membrane bioreactors in wastewater treatment, provides alternative technologies for arsenic treatment.
Emission Trajectories and Mitigation Schemes for China
by Kai Fang Qifeng Zhang Yiqi TangThis book seeks to model the possible emission trajectories and identify the feasible mitigation schemes for China to meet its climate commitments to peak emissions before 2030 and net zero emissions before 2060. In line with these ambitions, China has taken a number of measures to improve carbon efficiency and energy structure in recent years. The book first analyzes changes in the carbon footprint at the city level, identify the different pathways to peak emissions by province and industry, and develop a bottom-up approach to determining when and how China could reach peak emissions. It then illustrates how the Emissions Trading Scheme (ETS) reduces abatement costs, and examines the cost-saving effects under carbon intensity reduction and peak emissions targets. Based on the findings and the status quo in China, the authors propose a multicriteria allocation scheme for carbon emission allowances at the provincial level and quantify the impact of sectoral coverage on the abatement costs of the ETS by developing a cost-based approach to sectoral coverage in China. In addition, the co-benefits between CO2 and PM2.5 reductions as a result of the ETS operation are elaborated. The book will benefit researchers and policy-makers interested in environmental governance, climate policy, environmental economics, and sustainable development.
Emissions Trading: Principles and Practice
by Thomas H. TietenbergFirst published in 1985, Emissions Trading was a comprehensive review of the first large-scale attempt to use economic incentives in environmental policy in the U.S. and of the empirical and theoretical research on which this approach is based. Since its publication it has consistently been one of the most widely cited works in the tradable permits literature. The second edition of this classic study of pollution reform considers how the use of transferable permits to control pollution has evolved, looks at how these programs have been implemented in the U.S. and internationally, and offers an objective evaluation of the resulting successes, failures, and lessons learned over the last twenty-five years.

The book is divided into five sections covering the themes of remembering, understanding, mourning, belonging, and enchanting.
Emotional States: Sites and spaces of affective governance
by Jessica Pykett Eleanor Jupp Fiona M. SmithWhat is the political allure, value and currency of emotions within contemporary cultures of governance? What does it mean to govern more humanely? Since the emergence of an emotional turn in human geography over the last decade, the notion that our emotions matter in understanding an array of social practices, spatial formations and aspects of everyday life is no longer seen as controversial. This book brings recent developments in emotional geography into dialogue with social policy concerns and contemporary issues of governance. It sets the intellectual scene for research into the geographical dimensions of the emotionalized states of the citizen, policy maker and public service worker, and highlights new research on the emotional forms of governance which now characterise public life. An international range of empirical field studies are used to examine issues of regulation, modification, governance and potential manipulation of emotional affects, professional and personal identities and political technologies. Contributors provide analysis of the role of emotional entanglements in policy strategy, policy implementation, service delivery, citizenship and participation as well as considering the emotional nature of the research process itself. It will be of interest to researchers and students within social policy, human geography, politics and related disciplines.
Emperors of the Deep: Sharks—The Ocean's Most Mysterious, Most Misunderstood, and Most Important Guardians
by William McKeeverWhat we can learn from sharks—evolutionary marvels that have survived for 450 million years, and are essential to our planet’s ecosystem.We’re conditioned to see sharks as terrifying, cold-blooded underwater predators. But as Ocean Guardian founder William McKeever reveals, we need to ensure that their remarkable longevity continues. The first book to reveal in full the hidden lives of sharks, Emperors of the Deep focuses on four species—Mako, Tiger, Hammerhead, and Great White—as never before, including such fascinating details as:Sharks are 50 million years older than treesSharks have survived five extinction level events, including the one that killed off the dinosaursSharks have electroreception, a sixth sense that lets them pick up on electric fields generated by living thingsSharks can dive 4,000 feet below the surfaceSharks account for only six human fatalities per year, while humans kill 100 million sharks per yearMcKeever goes back through time to probe the shark’s prehistoric secrets and how it has become the world’s most feared, and most misunderstood, predator, and takes us on a pulse-pounding tour around the world and deep under the surface, from the frigid waters of the Arctic Circle to the coral reefs of the tropical Central Pacific. He also interviews ecologists, conservationists, and world-renowned shark experts, including the founders of Greenpeace’s Rainbow Warrior, the head of the Massachusetts Shark Research Program, and the self-professed “last great shark hunter.”At once a deep dive into the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates this wild species that hold the key to unlocking the mysteries of the ocean—if we can prevent their extinction from climate change and human hunters.“Many astonishing facts.” —The Guardian“[An] extraordinary book [that] rarely fails to inform and delight.” —The Washington TimesIncludes photographs
