The world is changing. Human population is surging towards 10 billion, food, water, climate and energy security are all at risk. Nitrogen could be our life raft in this global 'perfect storm'. Get it right and it can help to feed billions, fuel our cars and put a dent in global warming. Get it wrong and it will make things a whole lot worse.
This book helps to establish a simple framework to identify and use bird species as a bioindicator for high nature value (HNV) farmlands. This book focuses on suitable methods for monitoring the HNV areas, and presents the results of several case studies. The chapters put forward ways to integrate ecosystems assessment, geographical information systems (GIS) and strategies for conservation of local biodiversity. An innovative framework focuses on the use of species distribution models (SDMs) in order to explore the importance of each characteristic of HNV farmlands. Furthermore, the book examines the relationships among bird species richness, land use diversity and landscape metrics at a local scale in the farmlands.
The book introduces tourism earth-science as a new scientific discipline by applying the principles of earth-science in the study of natural and human tourism resources. It involves studying the geo-scientific characteristics of these tourism resources through surveys, evaluation and aesthetic value assessment. It also discusses about the principles behind geopark establishment and management. It is an important publication providing direction for geopark and tourism developments in China. The book is a tool for geological heritage survey, assessment and research. It can also be used to assist planning of geopark, national parks, heritage protection and scientific interpretation. It is a valuable teaching material for teachers and students of geoscience and tourism as well as providing useful guidance for geopark managers and tour guides in their operation. In addition, the book also offers scientific knowledge of the surrounding natural and cultural landscapes to the public and the general visitors.
This book provides results of spatial and temporal distributions of water quality parameters and marine primary production and its relationship with the driving atmospheric, ocean circulation and hydrobiological mechanisms established through a synergistic use of multi-spectral region spaceborne data and results of numerical model simulations of marine in-water and atmospheric processes related to the marine ecosystem. The changes in the studied marine/oceanic environments are analysed in light of recent climate change that imposes its influence through a set of forward and feedback interactions and forcing.
The geochemistry of the earth 's surface is controlled by chemical equilibrium, and the kinetics of the approach toward equilibrium. Many low temperature processes, such as weathering, do not reach equilibrium except over geologically long time periods. The approach to equilibrium can be described by kinetic theory and the application of kinetic theory to geochemical systems has made vast advances in the last several decades. Geochemical kinetics as a topic is now of importance to a wide range of geochemists in academia, industry, and government, and all geochemists need a rudimentary knowledge of the field. This book will summarize the fundamentals of geochemical kinetics with examples drawn especially from mineral dissolution and precipitation, but will also encompass discussion of high temperature processes and global geochemical cycle modeling. Analysis of textures of rocks, sediments, and mineral surfaces will be incorporated throughout and will be a subtheme of the book.
""What about the twenty-first century? Will we finally accept our responsibilities as guardians of planet Earth, the biological living trust, for the beneficiaries, the children of today, tomorrow, and beyond? Or, will it too be a century of lethal, economic struggle among the polarized positions of the supremely dysfunctional among us? Are they--once again--to be allowed to determine the legacy we, as a society, as a nation, bequeath those who follow us? The choice is ours, the adults of the world. How shall we choose?"" So writes Chris Maser in this compelling study of three interactive spheres of the ecosystem: atmosphere (air), litho-hydrosphere (rock that comprises the restless continents and the water that surrounds them), and biosphere (all life sandwiched in between). Rich in detail and insightful analogies, "Earth in Our Care" addresses key issues including land-use policies, ecological restoration, forest management, local living, and sustainability thinking. Exploring our interconnectedness with the Earth, Maser examines today's problems and, more importantly, provides solutions for the future.
This book discusses the problems and feasible remediation of fluoride contamination in groundwater. The book investigates applications of various carbons derived from bio-mass and bio-polymers. It also inquires into surface modified carbons that use inorganic ions to help remove excess fluoride ions in drinking water and wastewater effluents. The compliance of kinetic and isotherm models with fluoride sorption is covered, and the suggested mechanisms of defluoridation by surface modified carbon materials is described.
Scholarly Essay from the year 2010 in the subject Energy Sciences, grade: -, -, language: English, abstract: The paper identifies the necessity of a deep change process in the German wind industry. The need for change in the wind industry was given by the decision of the German government to finish nuclear energy production in the year 2022. The Fukushima accident lead to this decision and showed dramatically the urgency of finding solutions for a stable and sustainable energy production based on renewable energies. The advantages of using decentralized wind energy which is possible through installation of small wind turbines is so far less acknowledged in politics and economics. The amount of investment and the market share of small wind technology are minimal against their potential and compared to the investments which are put in centralized wind energy production with big 3 bladed turbines. The reduction of the costs for the transmission lines and the electrician transmission losses could be a major economical factor to the point that one could have a parallel grid to fulfil the requirements for power of special regions. To increase the percentage of decentralised produced wind energy it is necessary to identify the key reasons which minimise the success of the innovations in the field of small wind technology. Key factors are f.e. high costs for development and high governmental regulations as well as the lack of suitable technology. Another reason can be seen in the thinking of the core persons and decision makers in this business field as well as in politics. To be able to analyse the complex situation and get an understanding of the interconnection of different levels in this industry the systemic model by David Kantor is used which includes the normally less acknowledged level of mental models in economics.

Cirrus clouds are high, thin, tropospheric clouds composed predominately of ice. In the last ten years, considerable work has shown that cirrus is widespread--more common than previously believed--and has a signigicant impact on climate and global change. As the next generation weather satellites are being designed, the impact of cirrus on remote sensing and the global energy budget must be recognized and accommodated. This book, the first to be devoted entirely to cirrus clouds, captures the state of knowledge of cirrus and serves as a practical handbook as well. Each chapter is based on an invited review talk presented at Cirrus, a meeting hosted by the Optical Society of America and co-sponsored by the American Geophysical Union and the American Meteorological Society. All aspects of cirrus clouds are covered, an approach that reaches into diverse fields. Topics include: the definition of cirrus, cirrus climatologies, nucleation, evolution and dissipation, mixed-phase thermodynamics, crystallinity, orientation mechanisms, dynamics, scattering, radiative transfer, in situ sampling, processes that produce or influence cirrus (and vice versa), contrails, and the influence of cirrus on climate.
Tsunamis in the European-Mediterranean Region: From Historical Record to Risk Mitigation provides readers with a much needed, reliable, and up-to-date history of the region, including descriptions and parameters of the main events from pre-history to the present that are supported by parametric catalogues, pictorial material, and examples of instrumental records, such as tide-gauge records. The book presents a broader perspective of needed action for local and national governments, and international organizations, and is written by an internationally recognized expert in this field, providing an authoritative account of historical tsunamis in the eastern Mediterranean. It addresses key points of tsunami mitigation, including the systems currently available for tsunami recording, monitoring, and early warning, along with a presentation of the preventative measures that can be applied in all tsunami-vulnerable regions.
Seismic Exploration of Hydrocarbons in Heterogeneous Reservoirs: New Theories, Methods and Applications is based on the field research conducted over the past decade by an authoring team of five of the world's leading geoscientists. In recent years, the exploration targets of world's oil companies have become more complex. The direct detection of hydrocarbons based on seismic wave data in heterogeneous oil/gas reservoirs has become a hot spot in the research of applied and exploration geophysics. The relevant theories, approaches and applications, which the authors have worked on for years and have established mature technical processes for industrial application, are of significant meaning to the further study and practice of engineers, researchers and students in related area.

The aim of this book is to present an overview of the state of the art with regard to the function, application and design of TWSs in order to better protect surface water from contamination. Accordingly, it also presents applications of constructed wetlands with regard to climatic and cultural aspects. The use of artificial and natural treatment wetland systems (TWSs) for wastewater treatment is an approach that has been developed over the last thirty years. Europe is currently home to roughly 10,000 constructed wetland treatment systems (CWTSs), which simulate the aquatic habitat conditions of natural marsh ecosystems; roughly 3,500 systems are in operation in Germany alone. TWSs can also be found in many other European countries, for example 200 - 400 in Denmark, 400 - 600 in Great Britain, and ca. 1,000 in Poland. Most of the existing systems serve as local or individual household treatment systems. CWTSs are easy to operate and do not require specialized maintenance; further, no biological sewage sludge is formed during treatment processes. As TWSs are resistant to fluctuations in hydraulic loads, they are primarily used in rural areas as well as in urbanized areas with dispersed habitats, where conventional sewer systems and central conventional wastewater treatment plants (WWTPs) cannot be applied due to the high costs they would entail. TWSs are usually applied at the 2nd stage of domestic wastewater treatment, after mechanical treatment, and/or at the 3rd stage of treatment in order to ensure purification of effluent from conventional biological reactors and re-naturalization. New applications of TWSs include rainwater treatment as well as industrial and landfill leachate treatment. TWSs are well suited to these fields, as they can potentially remove not only organic matter and nitrogen compounds but also trace metals and traces of persistent organic pollutants and pathogens. Based on the practical experience gathered to date, and on new research regarding the processes and mechanisms of pollutant removal and advances in the systems properties and design, TWSs continue to evolve.
Geophysical Inverse Theory and Applications, Second Edition, brings together fundamental results developed by the Russian mathematical school in regularization theory and combines them with the related research in geophysical inversion carried out in the West. It presents a detailed exposition of the methods of regularized solution of inverse problems based on the ideas of Tikhonov regularization, and shows the different forms of their applications in both linear and nonlinear methods of geophysical inversion. It's the first book of its kind to treat many kinds of inversion and imaging techniques in a unified mathematical manner. The book is divided in five parts covering the foundations of the inversion theory and its applications to the solution of different geophysical inverse problems, including potential field, electromagnetic, and seismic methods. Unique in its focus on providing a link between the methods used in gravity, electromagnetic, and seismic imaging and inversion, it represents an exhaustive treatise on inversion theory. Written by one of the world's foremost experts, this work is widely recognized as the ultimate researcher's reference on geophysical inverse theory and its practical scientific applications.
This volume consists of 15 chapters and focuses on hazardous chemicals, how they are associated with plastics, and their environmental risks. It includes background information on plastics and additives chemistry, and their observed or potential effects on living organisms as well as the oceanographic aspects of marine debris dispersion. The respective chapters provide insights into the sorption/desorption of chemicals in and out of plastics, the mechanisms and kinetics, but also the scale of the concentrations of chemicals found in marine debris, particularly in microplastics. The occurrence of the various chemicals is analyzed, as well as the distribution profiles of the chemicals in microplastics throughout the world's oceans. The implications of the fact that plastics carry within them several chemicals are discussed in detail. In closing, new research topics that warrant further attention are identified. The book will appeal to all scientists who are already working or interested in starting to work on the topic of marine debris, as well as policymakers, NGOs and the broader informed public. |
