Groundwater Economics, Two-Volume Set (Hardcover, 2nd edition): Charles A. Job Groundwater Economics, Two-Volume Set (Hardcover, 2nd edition)
Charles A. Job
R6,730 Discovery Miles 67 300 Ships in 10 - 15 working days

Groundwater is a vitally important resource and as its use increases, the available supply is depleted, creating a ripple effect of impacts on both the environment and the economy that need to be disseminated to a larger audience of students and practitioners. This second edition of Groundwater Economics accomplishes just that. This two-volume set is a comprehensive work focused on the economic values of groundwater resources and use, and it reinforces the need for a strong economic rationale in decision-making relating to that use. This new edition includes a new chapter on sustainability as well as updating all chapters with a focus on sustainability. It thoroughly explains the economic value of groundwater for sustainable use and needs, with practical examples, and includes thirteen new and updated case studies on the economics of groundwater data for decision-making. It also addresses both local and regional groundwater economic choices through a series of applications at an international level. This set, written by a sustainability professional with decades of experience in managing groundwater use and protection, is written for other professionals as well as students, who need to understand and evaluate water resources and mange their use from a variety of sustainable approaches.

Managing Water Resources in a Time of Global Change - Contributions from the Rosenberg International Forum on Water Policy... Managing Water Resources in a Time of Global Change - Contributions from the Rosenberg International Forum on Water Policy (Paperback)
Alberto Garrido, Ariel Dinar
R1,418 Discovery Miles 14 180 Ships in 10 - 15 working days

Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice.

This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rh ne and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain.

By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

Water Resource Management - A Comparative Perspective (Hardcover, New): Dhirendra K. Vajpeyi Water Resource Management - A Comparative Perspective (Hardcover, New)

R2,558 Discovery Miles 25 580 Ships in 18 - 22 working days

According to available estimates, only .3% of the total fresh water is usable for the world's entire human and animal populations. Some experts have observed that in the near future, the earth will face severe scarcity of water, resulting in an insufficient amount of water to sustain our ever increasing future needs. Others believe that such pessimistic estimates are unwarranted.

Due to conflicting opinions and data-interpretations, the future levels of scarcity are difficult to accurately forecast. One fact, however, is above controversy: water resources are not evenly distributed. The world's 38 poorest countries are located near areas that lack ample water supplies. Even some areas, which seem to possess sufficient supplies, suffer zonal or regional shortages. In recent years there has been an increasing realization not only of the importance of water as a key factor for sustainable development, but also the impending strategies for water in the near future. The chapters in this collection examine this critical resource and the policies being pursued to meet the challenge of decreasing access to usable water by selected countries in Asia, Africa, Latin America, and Europe. A major study for students, researchers, and policymakers involved with environmental and development issues.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities. This book illustrates the diversity of transborder natural resources, the pressures that they experience or the opportunities that exist for multinational regulatory regimes, monitoring and enforcement. It presents ten case studies of transborder natural resources that are of interest to two or more neighboring countries, and that are subject to, or in need of bilateral or multinational coordinated management. The case studies include the exploitation of specific marine resources in international waters, rivers that travel through several countries and contiguous tropical forests across national borders, and where commodities, nature conservation or even territorial integrity are at stake. They are drawn from across the globe, including flood management in Western Europe, tropical forests in the Western Amazon, hydropower development in the Mekong region of South-east Asia, forest conservation in Central Africa and marine resource and fisheries exploitation in the waters of Japan, South-east Asia and Australia. Together the chapters provide a review of a wide range of transborder natural resource examples, and the diverse regulatory regimes that need to be devised to achieve successful management. An introductory chapter provides a conceptual and theoretical underpinning that can guide future research efforts on similar cases and a concluding chapter draws major conclusions and implications for related concepts and theories.

Modelling Human-Flood Interactions - A Coupled Flood-Agent-Institution Modelling Framework for Long-Term Flood Risk Management... Modelling Human-Flood Interactions - A Coupled Flood-Agent-Institution Modelling Framework for Long-Term Flood Risk Management (Paperback)
Yared Abayneh Abebe
R2,164 Discovery Miles 21 640 Ships in 10 - 15 working days

The negative impacts of floods are attributed to the extent and magnitude of a flood hazard, and the vulnerability and exposure of natural and human elements. In flood risk management (FRM) studies, it is crucial to model the interaction between human and flood subsystems across multiple spatial, temporal and organizational scales. Models should address the heterogeneity that exists within the human subsystem, and incorporate institutions that shape the behaviour of individuals. Hence, the main objectives of the dissertation are to develop a modelling framework and a methodology to build holistic models for FRM, and to assess how coupled human-flood interaction models support FRM policy analysis and decision-making. To achieve the objectives, the study introduces the Coupled fLood-Agent-Institution Modelling framework (CLAIM). CLAIM integrates actors, institutions, the urban environment, hydrologic and hydrodynamic processes and external factors, which affect FRM activities. The framework draws on the complex system perspective and conceptualizes the interaction of floods, humans and their environment as drivers of flood hazard, vulnerability and exposure. The human and flood subsystems are modelled using agent-based models and hydrodynamic models, respectively. The two models are dynamically coupled to understand human-flood interactions and to investigate the effect of institutions on FRM policy analysis.

R2,168 Discovery Miles 21 680 Ships in 10 - 15 working days

Urban climate adaptation currently focusses mainly on hazards but often ignores opportunities which arise in both space and time. Opportunistic Adaptation provides a rationalized approach to mainstream measures for climate adaptation into urban renewal cycles. Adaptation opportunities are identified by projecting the lifespans of urban assets into the future to obtain an operational urban adaptation agenda for the future. Upscaling of the adaptation process is done by synchronizing the end-of-lifecycle of a group of assets to develop adaptation clusters that comprise multiple dwellings, infrastructure as well as public spaces. An extensive catalogue of adaptation measures for different scale-levels ensures flexibility in the type of measures that can be integrated. Sequencing the adaptation measures over long periods of time provides insight and flexibility in the long-term protection standards that can be achieved. By applying a design-centered approach, the potentials of obtaining co-benefits in the urban landscape are maximized. Potentials of clustering of nature-based solutions are being considered which ensures to maximize the delivery of ecosystem services. This research aims to assess \the adaptation potential of Bangkok, based on a case study area (Lat Krabang) by mapping the adaptation opportunities and flood vulnerability. The resulting outputs will contribute to the development of a flexible and inclusive FRM strategy.

Water Loss Assessment in Distribution Networks - Methods, Applications and Implications in Intermittent Supply (Paperback):... Water Loss Assessment in Distribution Networks - Methods, Applications and Implications in Intermittent Supply (Paperback)
Taha M. Al-Washali
R2,657 Discovery Miles 26 570 Ships in 10 - 15 working days

Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.

Joan Hoffman
R4,510 Discovery Miles 45 100 Ships in 10 - 15 working days

How can we build the institutions that will promote the cooperation needed to meet our intertwined environmental and economic needs? Efforts to meet these twin goals in New York City 's watershed collaborations offer some guidance. The experience provides lessons in addressing scattered sources of pollution, encouraging environmentally compatible economic development, and coping with conflicts that are part of the collaboration process. It also yields insights into what we need to work effectively towards sustainable economic development.

This book identifies many barriers to achieving the cooperation necessary to solving our water problems and discusses how watershed collaborations are a means to overcoming those barriers. Historical experience and lessons from other watershed collaborations informed the design of New York City 's complex watershed collaboration which is shown to contain the elements of a "green milieu" that can foster sustainable economic development. The particular challenges to the collaboration 's environmental and economic goals created by the watershed 's rural economy, farming and forestry are described.

The unusual inclusion of the analysis of the economic aspects and effects of collaboration, of the relationship between collaboration and sustainable development, and of the processes of implementation and conflict make this book especially valuable to those interested in collaboration, regulation, environmental cooperation and conflict, watershed protection, economic development in general, and sustainable economic development in particular.

Efficient and equitable water, wastewater and stormwater management for the megacities is becoming an increasingly complex task. The special issue will focus on water management in its totality for megacities, including their technical, social, economic, legal, institutional and environmental dimensions through a series of specially invited case studies from different megacities of the world. At present, around one out of two of the earth's 6.3 billion people live in urban areas. Each year, the world population grows by around 80 millions. Practically all of this growth is urban, primarily due to migration. World's urban population is expected to reach 5 billion by 2030, which is nearly 2/3rd more than in 2000, and would mean that 60% of world's population will live in urban areas. The case studies analysed include some of the most interesting and challenging megacities of this planet, Dhaka, Istanbul, Jakarta, Johannesburg, Mexico City, Riyadh and Sao Paulo. They assess different aspects of how water is intermingled in the overall development milleau. The book considers the magnitudes, nature and extent of the present and future challenges and how these could be meet in socially acceptable and cost-effective ways. The contributors are all acknowledged water experts from different parts of the world. This book was previously published as a special issue of the International Journal of Water Resources Development.

R2,165 Discovery Miles 21 650 Ships in 10 - 15 working days

This research aims to investigate the prevailing sediment dynamics and the sediment budget in the Mekong Delta by using a process-based model. Understanding sediment dynamics for the Mekong Delta requires high resolution analysis and detailed data, which is a challenge for managers and scientists. This study introduces such an approach and focuses on modeling the entire system with a process-based approach with Delft3D-4 and Delft3D Flexible Mesh (DFM). The first model is used to explore sediment dynamics at the coastal zone. The latter model allows straightforward coupling of 1D and 2D grids, making it suitable for analyzing the complex river and canal network of the Mekong Delta. The validated model suggests that the Mekong Delta receives ~99 Mt/year sediment from the Mekong River. This is much lower than the common estimate of 160 Mt/year. Only about 23% of the modelled total sediment load at Kratie is exported to the sea. The remaining portion is trapped in the rivers and floodplains of the Mekong Delta. The results advance understanding of sediment dynamics and sediment budget in the Mekong Delta. As such the model is an efficient tool to support delta management and planning.

Globally, 2.7 billion people are using onsite sanitation systems, particularly in low income, high density settlements (LIHDS) in urban areas of developing countries. However, treatment technologies to manage the faecal sludge (FS) generated from these systems are often not in place, leading to high risks for environmental and public health. The development of replicable and effective technologies for FS treatment is key in addressing this challenge. This research focused on development of an innovative FS stabilisation technology and addressed key constraints in anaerobic FS treatment: inadequate pathogen inactivation and limitations in biochemical energy recovery. The developed two-stage reactor system consists of an acidogenic reactor fed with mixtures of FS and market waste to facilitate pathogen inactivation, and a subsequent methanogenic plug-flow reactor for enhanced methane production. Due to its potential for application as an off-site FS treatment technology at any scale, receiving any type of faecal matter, collected from different types of sanitary systems, the system provides an option for FS stabilisation for LIHDS. Additionally, the research evaluated the limitations of sanitation provision in LIHDS, and proposes methods for creating an enabling environment for full-scale implementation of onsite systems. The presented results contribute to designing appropriate sanitation interventions in LIHDS.

In many developing countries, water demand is increasing while surface- and groundwater resources are threatened by pollution and overexploitation. Hence, a more sustainable approach to water resources management and water treatment is required. In this capacity, bank filtration is a natural treatment process that makes use of the storage and contaminant attenuation capacity of natural soil/rock. However, BF is site-specific and a significant knowledge gap exists regarding the design and management of bank filtration systems, particularly in developing countries. This research aimed to address these gaps and contribute to the transfer of bank filtration to developing countries. This study comprised both column and batch laboratory-scale experiments to determine the effect of environmental variables such as temperature, raw water organic composition and redox conditions on the removal of chemical pollutants such as organic matter, micro-pollutants and heavy metals as well as the mobility of iron, manganese and arsenic under anaerobic conditions. Ultimately, the effectiveness of BF for supplying high drinking water quality was assessed in a case study in Egypt. The study showed that more than 80% of biodegradable organic matter was removed during infiltration at temperatures between 20 and 30 DegreesC. However, humic compounds enriched during BF, required post-treatment. Moreover, high humic content of infiltrating water reduced the removal of heavy metal and promoted the release of metal (loids) into the infiltrating water, rendering it more feasible to install BF wells within surface water systems with low levels of organic matter. Moderately-hydrophobic organic micropollutants were most persistent and required infiltration times longer than 30 days for complete elimination even at high temperatures (>20 DegreesC). Finally, design parameters such as the number of infiltration wells should be configured to minimise the proportion of polluted groundwater in the pumped water. Overall, this study provides insight into the effectiveness of BF in removing chemical pollutants from surface water and proposes guidelines for the successful application of BF in developing countries where arid conditions and high temperatures prevail.

The catchment area of the Mekong River and its tributaries extends from China, through Burma/Myanmar, Thailand, Laos, Cambodia and to Vietnam. The water resources of the Mekong region - from the Irrawaddy and Nu-Salween in the west, across the Chao Phraya to the Lancang-Mekong and Red River in the east- are increasingly contested. Governments, companies, and banks are driving new investments in roads, dams, diversions, irrigation schemes, navigation facilities, power plants and other emblems of conventional 'development'. Their plans and interventions should provide some benefits, but also pose multiple burdens and risks to millions of people dependent on wetlands, floodplains and aquatic resources, in particular, the wild capture fisheries of rivers and lakes. This book examines how large-scale projects are being proposed, justified, and built. How are such projects contested and how do specific governance regimes influence decision making? The book also highlights the emergence of new actors, rights and trade-off debates, and the social and environmental consequences of 'water resources development'. This book shows how diverse, and often antagonistic, ideologies and interests are contesting for legitimacy. It argues that the distribution of decision-making, political, and discursive power influences how the waterscapes of the region will ultimately look and how benefits, costs and risks will be distributed. These issues are crucial for the transformation of waterscapes and the prospects for democratizing water governance in the Mekong region. The book is part of the action-research of the M-POWER (Mekong Program on Water, Environment and Resilience) knowledge network.

Better water management will be crucial if we are to meet many of the key challenges of this century - feeding the world 's growing population and reducing poverty, meeting water and sanitation needs, protecting vital ecosystems, all while adapting to climate change. The approach known as Integrated Water Resources Management (IWRM) is widely recognized as the best way forward, but is poorly understood, even within the water sector. Since a core IWRM principle is that good water management must involve the water users, the understanding and involvement of other sectors is critical for success. There is thus an urgent need for practical guidance, for both water and development professionals, based on real world examples, rather than theoretical constructs. That is what this book provides. Using case studies, the book illustrates how better water management, guided by the IWRM approach, has helped to meet a wide range of sustainable development goals. It does this by considering practical examples, looking at how IWRM has contributed, at different scales, from very local, village-level experiences to reforms at national level and beyond to cases involving trans-boundary river basins. Using these on-the-ground experiences, from both developed and developing countries in five continents, the book provides candid and practical lessons for policy-makers, donors, and water and development practitioners worldwide, looking at how IWRM principles were applied, what worked, and, equally important, what didn t work, and why.
