The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Chapters "Sonocatalysis: A Potential Sustainable Pathway for the Valorization of Lignocellulosic Biomass and Derivatives", "Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods" and "Green and Sustainable Separation of Natural Products from Agro-Industrial Waste: Challenges, Potentialities, and Perspectives on Emerging Approaches" are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
Arguing that Antarctica is the most mediated place on earth and thus an ideal location for testing the limits of bio-political management of population and place, this book remaps national and postcolonial methods and offers a new look on a 'forgotten' continent now the focus of ecological concern.
This study analyzes the spatial-temporal pattern and processes of China's energy-related carbon emissions. Based on extensive quantitative analysis, it outlines the character and trajectory of China's energy-related carbon emissions during the period 1995-2010, examining the distribution pattern of China's carbon emissions from regional and sectoral perspectives and revealing the driving factors of China's soaring emission increase. Further, the book investigates the supply chain carbon emissions (the carbon footprints) of China's industrial sectors. Anthropogenic climate change is one of the most serious challenges currently facing humankind. China is the world's largest developing country, top primary energy consumer and carbon emitter. Achieving both economic growth and environmental conservation is the country's twofold challenge. Understanding the status, features and driving forces of China's energy-related carbon emissions is a critical aspect of attaining global sustainability. This work, for the first time, presents both key findings on and a systematic evaluation of China's carbon emissions from energy consumption. The results have important implications for global carbon budgets and burden-sharing with regard to climate change mitigation. The book will be of great interest to readers around the world, as it addresses a topic of truly global significance.
This comprehensive book covers the environmental issues concerning silver nanoparticles (AgNPs). Following an introduction to the history, properties and applications, the environmental concerns of AgNPs is discussed. In the second chapter, the separation, characterization and quantification of AgNPs in environment samples are described in detail. In the remaining parts of the book, the authors focus on the environmental processes and effects of AgNPs, with chapters on the pathway into environment, fate and transport, toxicological effects and mechanisms, as well as the environmental bioeffects and safety-assessment of AgNPs in the environment. This book is designed to describe current understanding of the environmental aspects of AgNPs. It provides a valuable resource to students and researchers in environmental science and technology, nanotechnology, toxicology, materials science and ecology; as well as to professionals involved in the production and consumption of AgNPs in various areas including catalysis, food products, textiles/fabrics, and medical products and devices. Jingfu Liu and Guibin Jiang are professors at State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.
This volume enables readers to understand the complexity associated with climate change policy and the science behind it. For example, the author describes the criticism and defense of the widely known hockey stick temperature graph derived from combining instrumental data and proxy temperature indications using tree ring, ice core and other paleoclimatic data. Readers will also learn that global warming cannot easily be avoided by reducing CO2 and other greenhouse gas emissions in rich countries. Not only is emissions reduction extremely difficult in rich countries, but demands such as the UN mandate to improve the lives of the poorest global citizens cannot be satisfied without significantly increasing global energy use, and CO2 emissions. Therefore, the author asserts that climate engineering and adaptation are preferable to mitigation, particularly since the science is less than adequate for making firm statements about the Earth s future climate.Readers will also learn that global warming cannot easily be avoided by reducing CO2 and other greenhouse gas emissions in rich countries.

Air pollution policy is closely connected with climate change, public health, energy, transport, trade, and agriculture, and generally speaking, the Earth has been pushed to the brink and the damage is becoming increasingly obvious. The transport sector remains a foremost source of air pollutants - a fact that has stimulated the production of biofuels. This book focuses on the biodiesel industry, and proposes a modification of the entire manufacturing chain that would pave the way for further improvements. Oil derived from oilseed plantations/crops is the most commonly used feedstock for the production of biodiesel. At the same time, the UK's Royal Academy of Engineering and 178 scientists in the Netherlands have determined that some biofuels, such as diesel produced from food crops, have led to more emissions than those produced by fossil fuels. Accordingly, this book re-evaluates the full cycle of biodiesel production in order to help find optimal solutions. It confirms that the production and use of fertilizers for the cultivation of crop feedstocks generate considerably more GHG emissions compared to the mitigation achieved by using biodiesel. To address this fertilization challenge, projecting future biofuel development requires a scenario in which producers shift to an organic agriculture approach that includes the use of microalgae. Among advanced biofuels, algae's advantages as a feedstock include the highest conversion of solar energy, and the ability to absorb CO2 and pollutants; as such, it is the better choice for future fuels. With regard to the question of why algae's benefits have not been capitalized on for biofuel production, our analyses indicate that the sole main barrier to realizing algae's biofuel potential is ineffective international and governmental policies, which create difficulties in reconciling the goals of economic development and environmental protection.
In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of emerging contaminants that may reach the soil and subsurface zones. New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a human lifetime scale ."
Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments
The book presents a wide description of hydrographic conditions in the studied area of the Norwegian and Greenland Seas. Variability of the Atlantic Water properties have been presented on the basis of time series obtained from oceanographic measurements performed each summer from 2000 to 2007 by the Institute of Oceanology Polish Academy of Sciences. The warming observed in that period has been described in detail as well as cooling of the Atlantic Water flowing towards the Fram Strait in 2007. Furthermore, concepts regarding multi-branch structure of the West Spitsbergen Current have been presented, types of flows in individual branches as well as variability of the flows. Description of the structure, transports and variability of the sea currents is based mostly on hydrographic measurements and baroclinic calculations. The results confirm a leading role of the ocean in climate shaping and acknowledges the importance of the Thermohaline Circulation for the climate.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
This volume provides an overview of the climate change adaptation objectives set, actions taken, and challenges faced by several countries in the Asia-Pacific region. The majority of the populations in this region struggle to make a living from subsistence agriculture, and livelihoods are highly dependent on natural ecosystem services which are likely to be severely affected by climate change. Cases discussed in this book highlight successes made by governments towards achieving adaptation objectives, and efforts required to overcome challenges. While significant economic advances have been made, the pace of growth has been slow to impact the lives of a majority of the people who live below the poverty line. The chapters highlight adaptation actions for protecting people and their livelihoods in priority sectors, maintaining food and water security, supporting socio-economic stability including poverty reduction, and climate risk management. This book also maximizes readers' insights into the knowledge gaps and limitations of stated adaptation goals, and the bottlenecks that hinder implementation in different regions.
We live on an increasingly human-dominated planet. Our impact on the Earth has become so huge that researchers now suggest that it merits its own geological epoch - the 'Anthropocene' - the age of humans. Combining theory development and case studies of 'planetary boundaries', emerging infectious diseases, financial markets and geoengineering, this groundbreaking book explores the 'Anthropocene Gap' otherwise known as society's current failure to address the most profound environmental challenges of our times. What are the political and institutional implications of this new epoch? And what are some novel ways to analyze the complicated interplay between institutions, Earth system complexity and technology? This book offers one of the first explorations of political and institutional dimensions of the Anthropocene concept by providing a novel combination of institutional analysis along with insights from Earth system sciences. It provides an exploration of the role of technology for global environmental governance and defines a new agenda for political science analysis in the Anthropocene. Offering the first summary of the planetary boundaries debate, this cutting edge book will be of great interest to researchers concerned in the interplay between politics, technology, and global environmental change, and those interested in the debate surrounding the Anthropocene and 'planetary boundaries'. Contents: Foreword. The 'Anthropocene Gap' 1. Planetary Terra Incognita 2. Governance and Complexity 3. Earth System Complexity 4. Epidemics and Supernetworks 5. Engineering the Planet 6. Financial Markets, Robots and Ecosystems 7. Bridging the 'Anthropocene Gap' Epilogue: Back to London via the Baltic Sea References Index
This bookintroduces a key issue in research on the climatic
impact of land cover and land use changes via terrestrial
biogeophysical processes. The parameterization of surface processes
and a systematic approach to modeling the climatic impacts of land
use change are discussed respectively, and can be used to improve
parameterization schemes for climate numerical models and to
provide a systematic method, thus offering more scientific and
enhanced support for research on the climatic effects of land
use/cover change. Further, based on predictions and scenario
analyses of land use changes in typical zones, the climatic impact
of various types of changes in different areas can be simulated
through climatic numerical modeling, the simulation results are
suitable for use in climate mitigation, land use planning, urban
development planning, etc. Thus, the book is intended for
researchers and professionals working in the area of meteorology
systems, climatic numerical modeling, climate change, and land
use/cover change, as well as decision makers in meteorology and
land use planning.
This thesis presents an impressive summary of the potential to use passive seismic methods to monitor the sequestration of anthropogenic CO2 in geologic reservoirs. It brings together innovative research in two distinct areas - seismology and geomechanics - and involves both data analysis and numerical modelling. The data come from the Weyburn-Midale project, which is currently the largest Carbon Capture and Storage (CCS) project in the world. James Verdon's results show how passive seismic monitoring can be used as an early warning system for fault reactivation and top seal failure, which may lead to the escape of CO2 at the surface.

The multidisciplinary team of authors offers insights into the latest technology of detection of pollen and its allergenic properties, forecasting methods, and the influence of allergenic pollen on the population. The comprehensive coverage in this book makes it an indispensible volume for anyone dealing with allergenic pollen worldwide. Readers involved in environmental health, aerobiology, medicine, and plant science will find this book of interest.
Contemporary cities face phenomenal risks, and they face particularly high levels of mounting social and environmental risks, including social polarization, urban conflicts, riots, terror, and climate change threats. This book suggests that climate change and its resulting uncertainties challenge the concepts, procedures, and scope of conventional approaches to planning, creating a need to rethink and revise current planning methods. Therefore, this book suggests a paradigm shift in our thinking, interrogation, and planning of our cities. Based on the contemporary conditions of risk at cities, this book conceptualizes the risk city as a construct of three interlinked concepts of risk, trust, and practice. It is a construct of risk and its new evolving conditions and knowledge of uncertainties stem from climate change and other risks and uncertainties. As a construct of practices, the risk city produces social and political institutional framework and promotes practices accordingly in order to reduce risk and risk possibilities and to increase trust. In light of the complex challenges and risks to the human habitat that have emerged in recent years, many cities have prepared various types of plans aimed at addressing the challenges posed by climate change. Nonetheless, despite the importance of these plans and the major public resources invested in their formulation, we still know little about them and have yet to begin studying them and assessing their contributions . From the innovative perspective of the risk city, this book asks critical questions about the nature, vision, practices, and potential impact of the recent climate change-oriented plans. What kinds of risks do they attempt to address, what types of practices do they institute, and what types of approaches do they apply? Do they adequately address the risks and uncertainties posed? How do they contribute to the worldwide effort to reduce greenhouse gas emissions? This book uses the methodologically innovative Risk City framework to examine the nature, vision, outcomes, practices, and impact of these crucial plans, as well as their contribution to the resilience of our cities and to global efforts toward reducing greenhouse gas emissions.
This book puts the spotlight on Southern Africa, presenting a cutting-edge concept never previously explored in the context of climate change and putting forward arguments for regional integration and cooperation. The Climate Resilient Infrastructure Development Facility (CRIDF) is the new water infrastructure program of the UK Department for International Development (DFID) for Southern Africa. The CRIDF promotes the establishment of small to medium-scale infrastructure across the Southern African Development Community (SADC) through technical assistance aimed at developing sustainable pro-poor projects, while also facilitating access to the financial resources needed to deliver said infrastructure. Further, it focuses on regional water resource management goals and basin plans, as well as on building climate resilience for the beneficiary communities. The Facility's Virtual Water and Nexus Project works to improve regional peace dividends by translating the Nexus concept into national and regional policies; it ultimately promotes sovereign security through greater regional integration across the water, food and energy sectors, while taking into account potential benefits in connection with carbon sequestration and emission mitigation.

It provides a balanced and comprehensive discussion of the core principles, novel plasma reactors and diagnostics, and state-of-the-art environmental applications of plasma. As such, it represents a valuable reference guide for scientists, engineers and graduate students in the fields of environmental science and plasma physics.
This study develops a new indicator for national and global sustainability. The main components of the EIIW-vita indicator are: the share of renewable energy, the genuine savings rate and the relative "green export" position of the respective countries; it is in line with OECD requirements on composite indicators. As green exports are related to technological progress and environmental-friendly products, there is also a Schumpeterian perspective of this indicator. An extended version furthermore looks at water productivity. The analysis highlights the BRIICS countries as well as the US, Germany, France, Spain, Italy, the UK and Japan. Moreover the special challenges and dynamics of ASEAN countries and Asia are discussed. The book derives key implications for economic and environmental policy and shows that the new global sustainability indicator is not only relevant for green progress, but also useful as a signal for international investors. The construction of the EIIW-vita global sustainability indicator is such that investors, citizens and governments can easily interpret the results. Correlation analysis of the new sustainability indicator with the human development index indicates complementarity, so that a new hybrid superindicator can be constructed. Sustainability rhetoric dominates environmental policy. This fresh assessment of key "pillars" of sustainable economic performance and growth is a valuable contribution to greening the economy, the leitmotiv of the latest Rio Earth Summit. The book places the discussion of sustainability on solid data. The rather surprising results of its new sustainability index should make policy makers rethink their environmental and economic strategies. Prof. Dr. Peter Bartelmus Columbia University, New York Many people put the economy first when sustainability concerns are raised, while environmental indicators are often developed without a sense of socio-economic performance. This important new book bridges the gap. It sheds light on crucial indicators such as renewable energies, exporting green goods and services, genuine savings, and water productivity. And it helps to observe the impressive changes at a global scale and in countries such as China. A must read for all experts interested in those issues. Prof. Dr. Raimund Bleischwitz University College London

This book combines soil science, earth science, and environmental geochemistry, providing comprehensive background information for specialists interested in chemical-induced changes in the soil-subsurface system. Readers are introduced to the chemistry of contaminants that often disturb the natural soil-subsurface equilibrium as a result of human activity. While the soil-subsurface system has in many cases been affected by human impact, the effects of chemical contaminants on the actual matrix and properties have been largely neglected. The major focus of the book is on changes to the soil-subsurface matrix and properties caused by chemical pollution. By integrating results available in the literature, we observe that chemical pollutants may lead to the irreversible formation of a new soil-subsurface regime characterized by a matrix and properties different than those of the natural regime. In contrast to the geological time scales dictating natural changes to the matrix and properties of the soil-subsurface system, the time scale associated with chemical pollutant-induced changes is far shorter and extends over a "human lifetime scale." The numerous examples presented in the book confirm that chemical contamination should be considered as an additional factor in the formation of a contemporary soil-subsurface regime that is different than that of the pristine system.
Leading scholars assess the transformations in energy security policy that flow from recognition of global climate change. They explore through case studies the key policy responses formulated in the Asia-Pacific and identify potential synergies between energy policy and climate mitigation efforts.
The over-exploitation of important earth resources such as land and water has led to a number of environment-related problems the world over. At the same time, land-use change caused by various human activities has led to extinction of many plant and animal habitats and species. In this context, the relevance of biodiversity for human survival is becoming a major international political issue as scientific evidence builds on the global health implications of biodiversity loss. These issues are closely linked with the issue of climate change, as many of the health risks due to climate change are associated with rapid degradation of biodiversity. This present work focuses on holistic natural resource-based spatio-temporal planning, development and management and considers them as essential to save the degraded ecosystem for sustainable resource management. Contributions are compiled in two volumes: 1. Climate Change and Biodiversity and 2. Landscape Ecology and Water Management. Geoinformatics along with its tools such as remote sensing and Geographical Information Systems (GIS) have been used in assessing the results of various environmental problems both physical and social. These volumes will be useful for geographers, geoscientists, hydrologists, landscape ecologists, environmentalists, engineers, planners and policy makers.
Deserts are unique ecosystems with their own biotic and abiotic components, and are often rich in renewable natural resources, the appropriate management of which can contribute significantly to the sustainable management of desert regions for the welfare of the people. Yet while there are many books on the flora of the countries fringing the important desert countries of the Mediterranean and Red Seas, there or few books reporting on their ecophysiology and vegetation ecology. This book presents the vegetation types of the African and Asian countries of the Mediterranean and Red Sea coastal regions, and discusses the ecological threats and economic applications of these critical resources. In particular, it examines the relationships between climate and vegetation, and discusses these within the context of desertification, agro-industrial applications, ecotourism and sustainable development. The book will provide a valuable reference for researchers and graduate students involved in plant ecology, biogeography, economic botany and environmental management in the Afro-Asian Mediterranean and Red Sea coastal regions, as well as other desert regions around the world.
This book discusses how climate change and heat islands are a main contributor to water related problems in urban areas in Kosice, Slovakia. Green roofs are used as a tool to assist in solving these water related issues. The need to provide housing in urban areas is expected to rise to 66% in 2050, according to the United Nations. Many urban areas have seen natural permeable green areas replaced with concrete constructions and hard, non-permeable surfaces. The densification of existing built-up areas is responsible for the decreasing vegetation, which results in the lack of evapotranspiration cooling the air, thereby creating urban heat islands. Several studies, discussed in this book, have shown that natural and permeable surfaces, as in the case of green roofs, can play a crucial role in mitigating this negative climate phenomenon and providing higher efficiency for buildings, leading to savings such as water, one of the focal points of this research. |
