Desertification and land degradation are complex phenomena, and we need to understand their causes, consequences, and means to mitigate and combat their impact. Therefore, this book aims to explain the concept and characteristics of drylands, desert and desertification, land degradation, wastelands, and the concept of ecosystem services. It also discusses various types of processes of land degradations, their characteristics, physics and indicators along with mapping, monitoring and assessment of methods involved. Concept of Ocean Biological Deserts is discussed along with international and regional efforts towards combating land degradation and desertification. Key Features: * Provides all the aspect of desertification and land degradation at one place * Includes comprehensive methods to monitor different desertification/land degradation processes * Comprehensive overview of the mapping, monitoring and modelling techniques * Role of space borne data in identifying, monitoring and combating desertification is evaluated and reported with real case studies * Explains the concept of ocean biological deserts, their characteristics and mapping

* Build more roads and congestion goes up, not down; improve engine efficiency and people drive more, increasing (as opposed to decreasing)emissions - these are examples of Jevons' Paradox, and clearly illustrate its importance in modern debates around resource use* From an international team of researchers, this is the first book to tackle the issues head-on - with special focus on the case of oil usage* Will be an essential addition to any economics, energy or resource management departmental bookshelf 'Jevons' Paradox', which was first expressed in 1865 by William Stanley Jevons in relation to use of coal, states that an increase in efficiency in using a resource leads to increased use of that resource rather than to a reduction. This has subsequently been proved to apply not just to fossil fuels, but other resource use scenarios. For example, doubling the efficiency of food production per hectare over the last 50 years (due to the Green Revolution) did not solve the problem of hunger. The increase in efficiency increased production and worsened hunger because of the resulting increase in population. The implications of this in today's world are substantial. Many scientists and policy makers argue that future technological innovations will reduce consumption of resources; Jevons' Paradox explains why this may be a false hope.This is the first book to provide a historical overview of Jevons' Paradox, provide evidence for its existence and apply it to complex systems. Written and edited by world experts in the fields of economics, technology and the environment, it explains the myth of efficiency and explores its implications for resource usage (particularly oil). It is a must read forpolicy makers, natural resource managers, academics and students concerned with the effects of efficiency on resource use.

Geothermal Heat Pumps is the most comprehensive guide to the selection, design and installation of geothermal heat pumps available. This leading manual presents the most recent information and market developments in order to put any installer, engineer or architect in the position to design, select and install a domestic geothermal heat pump system. Internationally respected expert Karl Ochsner presents the reasons to use heat pumps, introduces basic theory and reviews the wide variety of available heat pump models.

Energy has become a major element to Russia's attempts, under Putin, to restore its influence over former Soviet territories and reaffirm itself as the dominant regional power. This book investigates how Russia has manipulated the energy of its neighbours on Russian energy supplies to achieve its foreign policy goals, focusing in particular on relations with Ukraine. This book, based on a multitude of primary Ukrainian and Russian primary sources until now not brought to the attention of Western readers, examines important events such as Russia's January 2006 suspension of gas supplies to Ukraine, and the implications for Ukraine's 'Orange Revolution', other post-Soviet states and Western Europe. However, it goes further in showing how domestic political conditions in non-Russian states may facilitate Russia's use of energy as a foreign policy weapon, investigating the local groups that often receive significant profits from allowing Russia to control energy markets and energy transit possibilities. With European countries becoming more dependent upon Russian energy, this book will be of interest not only to Russian Studies and Eastern European Studies experts, but to scholars of international relations and European politics.

Precipitation drives the dynamics of flows and storages in water systems, making its monitoring essential for water management. Conventionally, precipitation is monitored using in-situ and remote sensors. In-situ sensors are arranged in networks, which are usually sparse, providing continuous observations for long periods at fixed points in space, and due to the high costs of such networks, they are often sub-optimal. To increase the efficiency of the monitoring networks, we explore the use of sensors that can relocate as rainfall events develop (dynamic sensors), as well as increasing the number of sensors involving volunteers (citizens). This research focusses on the development of an approach for merging heterogeneous observations in non-stationary precipitation fields, exploring the interactions between different definitions of optimality for the design of sensor networks, as well as development of algorithms for the optimal scheduling of dynamic sensors. This study was carried out in three different case studies, including Bacchiglione River (Italy), Don River (U.K.) and Brue Catchment (U.K.) The results of this study indicate that optimal use of dynamic sensors may be useful for monitoring precipitation to support water management and flow forecasting.

An increasing number of hydrological datasets from earth observations, hydrological models and seasonal forecasts have become available for water managers, consultants and the general public. These datasets are state-of-the-art products which are usually accessible online and may contribute to develop hydrological studies and support water resources management. However, the added value of these datasets has not been completely explored in decision-making processes. Research studies have assessed how well data can help in predicting climate, but there is a lack of knowledge on how well data can help in water allocation decisions. This work provides numerical tools, methods and results to evaluate the value of using hydrological datasets to support water allocation decisions at river basin and irrigation district scale. An integrated approach is used to predict climate, improve decisions and reduce negative impacts. Results show that investing in hydrological data with finer spatial and temporal resolution and longer periods of record improves water allocation decisions and reduces agricultural production loss in large irrigation schemes. Using river discharge data from hydrological models and global precipitation enhances irrigation area planning when little in-situ data is available. Moreover, using seasonal streamflow forecasts improves available water estimates resulting in better water allocation decisions. The framework was tested in Costa Rica, Colombia and Australia, but can be applied in any case study around the world.

[A] fascinating volume, which establishes marine environmental history as a major new discipline for academics as well as an exciting way to bring history and the natural world alive for the public. ANDREW A. ROSENBERG, UNIVERSITY OF NEW HAMPSHIRE The HMAP project is to be congratulated on this book, which presents vivid, evidence-based reconstructions of historical fisheries and the prolific ecosystems in which they were embedded. TONY J. PITCHER, UNIVERSITY OF BRITISH COLUMBIA The ingenuity and scholarship of the authors allow us to see ... how human societies have depended on and influenced marine living resources from periwinkles to whales. MIKE SINCLAIR, BEDFORD INSTITUTE OF OCEANOGRAPHY This book exalts the surprisingly fruitful marriage of historians and marine scientists - a union that has proven to be one of the most exciting developments in ocean research in recent years. KATHERINE RICHARDSON, UNIVERSITY OF COPENHAGEN For centuries the seas appeared to offer limitless supplies of food and other resources, their waters a cornucopia never to be exhausted. In more recent times, episodes such as the extreme exploitation and subsequent collapse of cod populations of the Grand Banks off Newfoundland have highlighted the fallaciousness of this view. Yet all too often the lessons from our historical interactions with marine animals are little known, let alone learned. Based on research for the History of Marine Animal Populations project, Oceans Past examines the complex relationship our forebears had with the sea and the animals that inhabit it. It presents eleven studies ranging from fisheries and invasive species to offshore technology and the study of marine environmental history, bringing together the perspectives of historians and marine scientists to enhance understanding of ocean management of the past, present and future. In doing so, it also highlights the influence that changes in marine ecosystems have upon the politics, welfare and culture of human societies.

One of the consequences of the post-socialist transformation of Eastern and Central Europe and the Former Soviet Union is the emergence of energy poverty, a condition where households are living in inadequately heated homes. This book provides the first full-length examination of the causes, consequences and patterns of energy poverty in former Communist countries. Based on empirical evidence that spans different spatial contexts and scales and compares these with other parts of the world, the book links household-level deprivation with broader organizational and political dynamics. The book also analyzes the lived experiences of scarcity and marginalization with the aid of two in-depth country studies. Furthermore, it identifies the socio-demographic factors that distinguish energy-poor families from the rest of the population, while stressing the need for a comprehensive range of policy tools to address energy poverty. As the issue of energy supply from the former Soviet Union is likely to become one of the most important economic and political problems across the whole of Europe within the next couple of decades, the book argues that there is a direct link between the energy crises experienced by the region, and the social aspects of energy use in households.

Water conflicts in India have now percolated to every level. They are aggravated by the relative paucity of frameworks, policies and mechanisms to govern the use of water resources. Based on the premise that understanding and documenting different types of water conflict cases in all their complexity would contribute to informed public debate and facilitate their resolution, Forum for Policy Dialogue on Water Conflicts in India, a collaborative initiative of the WWF project 'Dialogue on Water, Food and Environment', documented a number of such case studies. One of its kind in India, this book brings together an impressive sixty-three case studies - summarized status of the conflicts, the issues involved and their current position - and gives us a glimpse into 'the million revolts' that are brewing around water. While recognizing that each conflict is a microcosm of wider conflicts, the editors have classified these cases into eight broad themes that try to capture the dominant aspect of the conflict. These are: contending water uses; dams and displacement; equity-access-allocations; micro-level conflicts; water quality; trans-boundary conflicts; privatization; sand excavation and mining. With a mix of academics and activists as contributors, the book makes an important contribution to a new discourse on water in general, and water conflicts and conflict resolution in particular.

Originally published in 1972, this volume, supplemented extensively with maps and tables, and employing sophisticated institutional and empirical analyses, discusses a number of important issues relating to the viability of the Trans-Alaska Pipeline and the natural environment. The author concludes that exploiting North Slope oil was justifiable as a calculated risk, although an alternative route and transport mode to the Midwest of eastern market would be more attractive than TAP.

Originally published in 1977, this book concentrates on the period since nationalisation in the history of the coal industry. It provides not only a compact summary for those within the industry but also provides understanding of its problems and achievements for those outside it. The fluctuating world fuel situation threw the fortunes of the coal industry up and down and this book examines these changing fortunes within the context of the new challenges from North Sea oil and other newer sources of fuel.

Originally published in 1987 this book presents a comprehensive survey of the global natural gas industry: it looks at the problems of supply, the pattern of demand, the economics of the industrya nd how the industry in the 1980s was being affected by changes in other energy sectors. As a key commodity in the world economy the supply of natural gas is increasingly affecting and changing international relations between importer and supplier countries: the siberian natural gas pipeline which supplies Soviet gas to Western Europe is a key example of the impact of natural gas on international relations and one which is discussed in the book.

Although valuable resources in river basins and other aqueous environments, sediments often receive much less attention from researchers, policymakers, and other professionals than other components of the ecosystem. Until now. Highlighting the important role that sediments play in the geoenvironment, Sediments Contamination and Sustainable Remediation focuses on sediment management for the purpose of environmental cleanup or management. It provides the in-depth understanding of the sediment-water environment needed to develop better management practices and meet sustainability requirements. The book discusses the contamination of sediments resulting from discharge of pollutants, excessive nutrients, and other hazardous substances from anthropogenic activities. It examines impacts observed as a result of these discharges, including the presence of hazardous materials and eutrophication, and elucidates the remediation techniques developed to restore the health of sediments and how to evaluate the remediation technologies using indicators. The text explores the problems inherent in dealing with contaminated sediments in rivers, lakes, and estuaries and includes numerous case studies that illustrate key concepts. The authors provide wide-ranging coverage of the topic and include methods for evaluating the effectiveness of different remediation technologies. They make the case for the development and application of innovative management practices that create long-term solutions to sediment contamination to reduce natural resource depletion, continued landfill contamination, and diminished biodiversity in the aquatic geoenvironment.

The literature of hydrology abounds with texts on the hydrological and water resource problems in humid regions. However, this is not the case for the arid or semi arid regions. The situation is exemplified by the fact a concrete definition for the term "wadi", as accepted by UNESCO for describing these areas, is difficult to find. Arguably the first book devoted entirely to examining this important resource, Wadi Hydrology presents methodologies for sustainable management of wadis and their water resources. Through unique physical approaches, field cases, sample interpretations, and various applications to different models, this book provides an in-depth understanding of these systems that illustrates the efficiency of harnessing water from wadis. The author compiles the most up-to-date information on arid region hydrology, including specific techniques for hydrological calculations and desertification assessments, and includes examples and solved problems in each chapter.

Douglas F. Barnes and his team of development experts provide an essential guide that can help improve the quality of life of the estimated 1.3 billion rural people in the world who are without electricity.

The difficulties in bringing electricity to rural areas are formidable: Low population densities result in high capital and operating costs. Consumers are often poor and their electricity consumption is low. Politicians interfere with the planning and operations of programs, insisting on favored constituents. Yet, as Barnes and his contributors demonstrate, many countries have overcome these obstacles. The Challenge of Rural Electrification provides lessons from successful programs in Bangladesh, Chile, China, Costa Rica, Mexico, the Philippines, Thailand, and Tunisia, as well as Ireland and the United States. These insights are presented in a format that is accessible to a broad range of policy makers, development professionals, and community advocates.

Barnes and his contributors do not provide a single formula for bringing electricity to rural areas. They do not recommend a specific set of institutional arrangements for the participation of public sector companies, cooperatives, and private firms. They argue instead that successful programs follow a flexible but still well-defined set of principles: a financially viable plan that clearly accounts for any subsidies; a cooperative relationship between electricity providers and local communities; and an operational separation from day-to-day government and politics.

A timely contribution and incisive analysis, this is the story of the British experiment in privatizing the nuclear power industry and its subsequent financial collapse. It tells how the UK's pioneering role in nuclear power led to bad technology choices, a badly flawed restructuring of the electricity industry and the end of government support for nuclear power. In this volume Simon Taylor has combined interviews with former executives, regulators and analysts with his own unique insight into the nuclear industry to provide an analysis of the origins of the crisis and the financial and corporate strategies used by British Energy plc. Arguing that the stock market was a major factor in the company's collapse by misunderstanding its finances, over-valuing the shares and giving wrong signals to management and that the government policy of trying to put all responsibility for nuclear liabilities in the hands of the private sector was neither credible nor realistic. The book concludes that failure was not inevitable but resulted from a mixture of internal and external causes that casts doubt on the policy of combining a wholly nuclear generator with liberalized power markets. This book will be of great interest to students engaged with the history of nuclear power in the UK, privatization, regulation and financial and corporate strategy, as well as experts, policy makers and strategists in the field.

Hazardous Industrial Waste Treatment provides technical and economical information on how to develop the most feasible total environmental control program that can benefit both industry and local municipalities.

This volume, originally published in 1984, analyzes the impact of the 1973-74 oil price increases on the Appalachian coal industry in the USA, which would otherwise have suffered large output reductions as a result of sulfur emission restrictions. Although focussed on a particular geographical region and timeframe, this book has enduring relevance as it analyzes and discusses many of the issues which are still facing the ailing coal mining industries both in the USA and globally: the advent of new energy forms, increased competition from cheaper sources, strict pollution legislation and the impact that all of these issues have on productivity and employment.

Originally published in 1994, this book contains the edited papers of the workshop of the Energy and Environmental Programme at the Royal Institute of Interantional Affairs which examined the interaction between environmental legislation and the energy indusutries. It examines past experience; the nature of the challenges to the industries; actual industrial responses and what implications this might have framing legislation. The international contributors represent a range of perspectives.

Intensifying Activated Sludge Using Media-Supported Biofilms will be of interest to practicing wastewater treatment process designers, along with those seeking more compact and energy-efficient wastewater treatment options. The advantages of Moving Bed Biological Reactor (MBBR)-based hybrid processes are now well-established in practice, leading to their increased use in the field. Membrane Aerated Biofilm Reactor (MABR)-based hybrid processes are much newer and offer further systematic process and energy advantages. This book examines the evolution of hybrid technologies as well as the potential for continued improvement of biological wastewater treatment techniques. Features: Reviews current approaches for intensifying biological wastewater treatment processes and their mechanistic bases. Examines hybrid suspended growth/biofilm-based wastewater treatment processes, including the newly-developed MABR-based processes, and their unique dynamic performance characteristics. Presents a novel method for characterizing the performance and process intensification advantages of hybrid processes. Provides guidance for simulating the performance of hybrid processes, including oxygen transfer in MABR hybrid processes.

Bringing together leading-edge research and innovative energy markets econometrics, this book collects the author's most important recent contributions in energy economics. In particular, the book:* applies recent advances in the field of applied econometrics to investigate a number of issues regarding energy markets, including the theory of storage and the efficient markets hypothesis* presents the basic stylized facts on energy price movements using correlation analysis, causality tests, integration theory, cointegration theory, as well as recently developed procedures for testing for shared and codependent cycles* uses recent advances in the financial econometrics literature to model time-varying returns and volatility in energy prices and to test for causal relationships between energy prices and their volatilities* explores the functioning of electricity markets and applies conventional models of time series analysis to investigate a number of issues regarding wholesale power prices in the western North American markets* applies tools from statistics and dynamical systems theory to test for nonlinear dynamics and deterministic chaos in a number of North American hydrocarbon markets (those of ethane, propane, normal butane, iso-butane, naptha, crude oil, and natural gas)

This book examines Nile water security through the morphology of the river: it uses the always changing form of the river as a theoretical and empirical device to map and understand how infrastructures and discourses dynamically interact with the Nile. By bringing a history of two centuries of dam development on the Nile in relation with the drainage of a hill slope in Ethiopia on the one hand and irrigation reform in Sudan on the other, the author shows how the scales, units and 'populations' figuring in projects to securitize the river emerge through the rearrangement of its water and sediments. The analysis of 'Making water security' is more than yet another story of how modern projects of water security have legitimized often violent dispossessions of Nile land and water. It shows how no water user is confined by the roles assigned by project engineers and planners. As ongoing modern 'development' of the river reduces the prospects for new large diversions of water, the targeted subjects of development and modernization make use of newly opened spaces to carve out their own projects. They creatively mobilize old irrigation and drainage infrastructures in ways that escape the universal logic of water security.

Seawater desalination is increasingly being used as a means to augment freshwater supplies in regions with high water stress, and reverse osmosis is increasingly the technology of choice because of the low energy consumption. However, seawater reverse osmosis (SWRO) systems suffer from various types of fouling, which can increase energy consumption and the use of chemicals during SWRO operation. In practice, pre-treatment systems are put in place to reduce the particulate and biological fouling potential of SWRO feed water. However, simple, reliable and accurate methods to assess the extent to which biological fouling potential is reduced during pre-treatment are not available for seawater. This research developed a new method to measure bacterial growth potential (BGP) using the native bacterial consortium in seawater. New reagents to extract and detect ATP in microbial cells were specifically developed for seawater. The new lysis and detection reagents overcame the salt interference in seawater and allow low detection of total ATP, free ATP and microbial ATP in seawater. Incorporating a filtration step further increased the sensitivity of the method six fold, enabling ATP detection of ultra-low levels of microbial ATP in seawater. The newly developed ATP-based BGP method was applied to monitor and assess the pre-treatment of five full-scale seawater desalination plants around the world. A good correlation was observed between BGP measured in SWRO feed water and the pressure drop increase in the SWRO systems, suggesting the applicability of using the ATP-based BGP method as a biofouling indicator in SWRO. Furthermore, a safe level of BGP (<70 g/L) is proposed for SWRO feed water in order to ensure a chemical cleaning frequency of once/year or lower. However, to validate this conclusion, more SWRO plants with different pre-treatment systems need to be monitored. In the future, on-line monitoring of BGP in SWRO feed water may further reduce the consumption of chemicals and energy and improve the overall sustainability of seawater desalination by reverse osmosis.

Whereas the global water community may have reached consensus on the need for water providers to operate on the basis of commercial principles, staff of water utilities are faced with the challenge of implementing these principles in their everyday work. In the everyday domain, these principles appear to directly conflict with the mandate of water operators to provide water services to all. Moreover, the socio-political, economic and bio-physical context in which these water operate may be ill-suited to implement commercialization. In pursuing commercialization these operators adapt, reinterpret, modify, deflect, alter or betray the original principles of commercialization during implementation. This research takes inspiration from the rich literature on policy implementation and policy translation, which argues that policy models need to be transformed and modified if they are to be successfully adopted or implemented. This research analyzes the alterations visible in the daily implementation of commercial models of water provisioning and, in doing so, present a better understanding of how water operators implement policy prescriptions of commercialization in practice. Based on the analysis of the adaptations and (re)interpretations of the implemented model of commercialization in the different cases, this thesis argues that a new way of speaking about commercialization should be developed.
