This book presents a summary of terrestrial microbial processes, which are a key factor in supporting healthy life on our planet. The authors explain how microorganisms maintain the soil ecosystem through recycling carbon and nitrogen and then provide insights into how soil microbiology processes integrate into ecosystem science, helping to achieve successful bioremediation as well as safe and effective operation of landfills, and enabling the design of composting processes that reduce the amount of waste that is placed in landfills. The book also explores the effect of human land use, including restoration on soil microbial communities and the response of wetland microbial communities to anthropogenic pollutants. Lastly it discusses the role of fungi in causing damaging, and often lethal, infectious diseases in plants and animals.
Interdisciplinary Teaching about the Earth and Environment for a Sustainable Future presents the outcomes of the InTeGrate project, a community effort funded by the National Science Foundation to improve Earth literacy and build a workforce prepared to tackle environmental and resource issues. The InTeGrate community is built around the shared goal of supporting interdisciplinary learning about Earth across the undergraduate curriculum, focusing on the grand challenges facing society and the important role that the geosciences play in addressing these grand challenges. The chapters in this book explicitly illustrate the intimate relationship between geoscience and sustainability that is often opaque to students. The authors of these chapters are faculty members, administrators, program directors, and researchers from institutions across the country who have collectively envisioned, implemented, and evaluated effective change in their classrooms, programs, institutions, and beyond. This book provides guidance to anyone interested in implementing change-on scales ranging from a single course to an entire program-by infusing sustainability across the curriculum, broadening access to Earth and environmental sciences, and assessing the impacts of those changes.
Emerging Spatial Big Data (SBD) has transformative potential in solving many grand societal challenges such as water resource management, food security, disaster response, and transportation. However, significant computational challenges exist in analyzing SBD due to the unique spatial characteristics including spatial autocorrelation, anisotropy, heterogeneity, multiple scales and resolutions which is illustrated in this book. This book also discusses current techniques for, spatial big data science with a particular focus on classification techniques for earth observation imagery big data. Specifically, the authors introduce several recent spatial classification techniques, such as spatial decision trees and spatial ensemble learning. Several potential future research directions are also discussed. This book targets an interdisciplinary audience including computer scientists, practitioners and researchers working in the field of data mining, big data, as well as domain scientists working in earth science (e.g., hydrology, disaster), public safety and public health. Advanced level students in computer science will also find this book useful as a reference.
This book examines two mid-nineteenth century thinkers - the Austrian writer Adalbert Stifter and the French architect Eugene E. Viollet-le-Duc - who imagined cultural history on the model of earth history: as a history of objects to be restored and worlds to be reconstructed. The nascent field of geology shaped cultural thought; their conservationism, informed by erosion, envisions a future of restorative renewal.
This book is the result of collaboration within the framework of the Third International Scientific School for Young Scientists held at the Ishlinskii Institute for Problems in Mechanics of Russian Academy of Sciences, 2017, November. The papers included describe studies on the dynamics of natural system - geosphere, hydrosphere, atmosphere-and their interactions, the human contribution to naturally occurring processes, laboratory modeling of earth and environment processes, and testing of new developed physical and mathematical models. The book particularly focuses on modeling in the field of oil and gas production as well as new alternative energy sources.
The book presents a state-of-the-art overview of current developments in the field in a way accessible to attendees coming from a variety of fields. Relevant examples are turbulence research, (environmental) fluid mechanics, lake hydrodynamics and atmospheric physics. Topics discussed range from the fundamentals of rotating and stratified flows, mixing and transport in stratified or rotating turbulence, transport in the atmospheric boundary layer, the dynamics of gravity and turbidity currents eventually with effects of background rotation or stratification, mixing in (stratified) lakes, and the Lagrangian approach in the analysis of transport processes in geophysical and environmental flows. The topics are discussed from fundamental, experimental and numerical points of view. Some contributions cover fundamental aspects including a number of the basic dynamical properties of rotating and or stratified (turbulent) flows, the mathematical description of these flows, some applications in the natural environment, and the Lagrangian statistical analysis of turbulent transport processes and turbulent transport of material particles (including, for example, inertial and finite-size effects). Four papers are dedicated to specific topics such as transport in (stratified) lakes, transport and mixing in the atmospheric boundary layer, mixing in stratified fluids and dynamics of turbidity currents. The book is addressed to doctoral students and postdoctoral researchers, but also to academic and industrial researchers and practicing engineers, with a background in mechanical engineering, applied physics, civil engineering, applied mathematics, meteorology, physical oceanography or physical limnology.
Bioremediation is the use of microorganisms' metabolism to degrade waste contaminants (sewage, domestic, and industrial effluents) into non-toxic or less toxic materials by natural biological processes. Volume 2 offers new discussion of remediation through fungi-or mycoremediation-and its multifarious possibilities in applied remediation engineering and the future of environmental sustainability. Fungi have the biochemical and ecological capability to degrade environmental organic chemicals and to decrease the risk associated with metals, semi-metals, noble metals, and radionuclides, either by chemical modification or by manipulating chemical bioavailability. Additional expanded texts shows the capability of these fungi to form extended mycelia networks, the low specificity of their catabolic enzymes, and their use against pollutants as a growth substrate, making these fungi well suited for bioremediation processes. Their mycelia exhibit the robustness of adapting to highly limiting environmental conditions often experienced in the presence of persistent pollutants, which makes them more useful compared to other microbes. Despite dominating the living biomass in soil and being abundant in aquatic ecosystems, however, fungi have not been exploited for the bioremediation of such environments until this added Volume 2. This book covers the various types of fungi and associated fungal processes used to clean up waste and wastewaters in contaminated environments and discusses future potential applications.

Water Relations of Plants and Soils, successor to the seminal 1983
book by Paul Kramer, covers the entire field of water relations
using current concepts and consistent terminology. Emphasis is on
the interdependence of processes, including rate of water
absorption, rate of transpiration, resistance to water flow into
roots, soil factors affecting water availability. New trends in the
field, such as the consideration of roots (rather than leaves) as
the primary sensors of water stress, are examined in detail.

This reference work is for beginners, graduates, and postgraduates who are interested in the subject and intend to venture into serious research. This hybrid text/reference is for beginners, academics, and professionals who intend to document sea level dynamics on long and short time scales and resultant habitat and paleobiodiversity changes.
Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity po tential. Rational soil management practices must allow environmentally and economically sustain able yields and restoration of soil health.

This 4-volume set focuses on the use of microbial bioremediation and phytoremediation to clean up pollutants in soil, such as pesticides, petroleum hydrocarbons, metals, and chlorinated solvents, which reduce the soil's fertility and renders it unfit for plant growth. The volumes cover the many diverse eco-friendly microbial bioremediation and phytoremediation techniques for sustainable soil management. Bioremediation and Phytoremediation Technologies in Sustainable Soil Management: Volume 1: Fundamental Aspects and Contaminated Sites begins with an overview of phytoremediation and phytotechnologies and the role of environmental factors. It goes on to introduce soil assessment techniques and offers methods of remediation designed to combat soil and agricultural degradation. Attention is given to specific types of sites and soil pollution, such as soils contaminated by heavy metals; microbial and phytoremediation-based removal of polycyclic aromatic hydrocarbons (PAHs) from coal, crude oil, and gasoline; microbial bioremediation and amelioration of pesticide-contaminated soils; phytoremediation techniques for biomedical waste contaminated sites; as well as biomediation processes for human waste sites. Biopesticides are also explained in the book as an alternative to conventional pesticides as well as the possibilities for the improvement of modern bio-pesticides. Volume 2: Microbial Approaches and Recent Trends focuses on new and emerging techniques and approaches to address soil pollution. These include the use of rhizobacteria, archae, cyanobacteria, and microalgae as biofertilizers and for soil bioremediation efforts. New technologies for assessment of soil bioremediation are explored also. The chapters provides in-depth coverage of the mechanisms, advantages, and disadvantages of the technologies used and highlights the use of different microbial enzymes that are used in the process of bioremediation and phytoremediation to clean up different pollutants without causing damage to the natural environment. Volume 3: Inventive Techniques, Research Methods, and Case Studies is organized in three themes: plants in green remediation, tools and techniques in bioremediation and phytoremediation, and special sites and their remediation techniques. Innovative new techniques that advance the use of molecular biological approaches, nanotechnology, immobilization, vermicomposting and genetic modification developments are investigated to take advantage of these possibilities. Volume 4: Degradation of Pesticides and Polychlorinated Biphenyls addresses pesticide degradation, PCBs degradation, and genetic interventions. It begins by describing environment pesticide degradation, mechanisms and sustainability, microbes and microbial enzymes, plant microbe interactions, organophosphorus degradations and endosulfan degradation. It then goes on to discuss PCBs and degradation, cypermethrin, degradation by Phanerochaete chrysosporium, carvone and surfactants for degradation of PCBs. The book also advocates for genetic systems for degradation of PCBs and pesticides, with discussion of the different advantages and disadvantages for each strategy and the various techniques. Together, these four volumes provide in-depth coverage of the mechanisms, advantages, and disadvantages of the bioremediation and phytoremediation technologies for safe and sustainable soil management. The diverse topics help to arm biologists, agricultural engineers, environmental and soil scientists and chemists with the information and tools they need to address soil toxins that are a dangerous risk to plants, wildlife, humans and, of course, the soil itself.
Understanding and protecting our environment is a key component of
environmental development, yet access to a wide range of
high-quality information is currently based on very limited data
due to lack of the exchange of data between source and recipient.
This volume represents an effort to bring together communities of land-based hydrogeology and marine hydrogeology. The issues of submarine groundwater discharge and its opposite phenomenon of seawater invasion are discussed in this book from the geophysical, geochemical, biological, and engineering perspectives. This is where land hydrogeology and marine hydrogeology overlap. Submarine groundwater discharge is a rapidly developing research field. The SCOR and LOICZ of the IGBP have recently established a working group for this research. IASPO and IAHS under IUGG also recently formed a new joint committee "Seawater/Groundwater Interactions" to collaborate with oceanographers and hydrologists.
The book examines a new concern in water quality policy, namely aquatic micropollutants. Micropollutants are chemicals detected in small concentrations in waterbodies today, originating from pharmaceuticals, cosmetics, or detergents, among others. Since the regulation of micropollutants is a fairly new issue, it has been largely neglected in social sciences. However, the search for appropriate solutions is of high political relevance at both the national and international levels, with many open questions arising that concern the most adequate governance structures and steering mechanisms. Solutions suitable for classical, macro-pollutants, such as nutrients, do not necessarily apply to micropollutants because of the diversity of compounds and sources, and for technical, financial, and societal reasons. The book addresses this knowledge gap by investigating the steering mechanisms at hand and their prospect for problem solving. In this regard, the research provides a systematic depiction and comparison of policy designs in place for the reduction of micropollutants in the Rhine basin. Moreover, the study yields insights into the governance structures in place, into actors' responsibilities and constellations, and policy processes regarding micropollutants. The study is furthermore embedded into broader theoretical questions of policy research. More precisely, this research is a contribution to policy analysis that aims to achieve more optimal policy results by providing for a better understanding of the nature of policy designs and the social mechanisms behind the choice of them. Despite the intrinsic aim of policy analysis at contributing to more optimal policy outcomes, there remains a lack of research regarding analytical tools that enable an ex-ante assessment of policy designs' problem-solving abilities. To explore such a research path, this book proposes a novel index of policy comprehensiveness for quantifying the prospective performance of policy designs in alleviating an underlying policy issue, e.g. reducing pollutants in waters. Furthermore, the book uncovers the social mechanisms behind policymaking and turns to the question: In which social settings is it possible to achieve a comprehensive policy design? Compared to purely micro-level explanations, the advantage of the network approach is that it goes beyond the mere aggregation of policy actors' attributes by taking into consideration actors' interdependencies. In order to take the network approach seriously, the study systematically links the structure of a policy network with comprehensive policy designs. Network concepts, such as coalition structure, interconnectedness, and belief similarity, are employed from policy change research here in order to explore the link between structural network characteristics and comprehensive policy design. By studying how network structures affect policy design, the book critically examines the explanatory value of the network approach.
This book explores ancient efforts to explain the scientific, philosophical, and spiritual aspects of water. From the ancient point of view, we investigate many questions including: How does water help shape the world? What is the nature of the ocean? What causes watery weather, including superstorms and snow? How does water affect health, as a vector of disease or of healing? What is the nature of deep-sea-creatures (including sea monsters)? What spiritual forces can protect those who must travel on water? This first complete study of water in the ancient imagination makes a major contribution to classics, geography, hydrology and the history of science alike. Water is an essential resource that affects every aspect of human life, and its metamorphic properties gave license to the ancient imagination to perceive watery phenomena as the product of visible and invisible forces. As such, it was a source of great curiosity for the Greeks and Romans who sought to control the natural world by understanding it, and who, despite technological limitations, asked interesting questions about the origins and characteristics of water and its influences on land, weather, and living creatures, both real and imagined.
This book sets out to give a rigorous mathematical description of the greenhouse effect through the theory of infrared atmospheric emission. In contrast to traditional climatological analysis, this approach eschews empirical relations in favour of a strict thermodynamical derivation, based on data from NASA and from the HITRAN spectroscopy database. The results highlight new aspects of the role of clouds in the greenhouse effect. |
