Climate Change and Development Impacts on Groundwater Resources in the Nile Delta Aquifer, Egypt (Paperback): Marmar Badr... Climate Change and Development Impacts on Groundwater Resources in the Nile Delta Aquifer, Egypt (Paperback)
Marmar Badr Mohamed Ahmed
R2,046 Discovery Miles 20 460 Ships in 12 - 17 working days

Climate change is likely to continue to have severe impacts, including sea level rise. At the same time, population increase and development imperatives create additional pressure on available water resources. These changes are problematic for the Mediterranean coastal areas and especially the Nile Delta coast. Particular focus of this study is on salinization of groundwater resources in the Nile Delta Aquifer (NDA) due to saltwater intrusion. To assess current conditions and develop future adaptation strategies for the NDA, a 3D model simulating regional variable-density groundwater flow and coupled salt transport was constructed based on available data set, using the SEAWAT code. A method for identification of the most representative model has been developed, based on testing different simulation periods during which the NDA has 'evolved' from completely fresh groundwater conditions to conditions representative for the year 2010.This model was then applied to analyze possible future NDA conditions under several predefined scenarios of sea level rise and groundwater extraction. This analysis indicated that the impacts from further extractions of groundwater on availability of fresh groundwater in the aquifer are more significant compared to those from sea level rise. Furthermore, three different adaptation measures and their impacts in the Sharkeya Nile Delta governorate were tested. It was shown that that changing crop types and irrigation practices towards water saving options seem to be more promising than artificial recharge with injection wells or extraction and usage of brackish groundwater after desalination. The developed model is useful for further Water-Food Nexus studies.

R2,291 Discovery Miles 22 910 Ships in 12 - 17 working days

The spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the Dinder and Rahad basins in Sudan is confronted by the lack of climatic, hydrological and ecological data. This book investigated the impacts of land degradation on the Dinder and Rahad hydrology and morphology, and interlinkage to the ecohydrological system of the Dinder National Park (DNP) in Sudan. It used an ensemble of techniques to improve our understanding of the hydrological processes and LULC changes in these basins. This included long-term trend analysis of hydroclimatic variables, LULC changes analysis, field measurements, rainfall-runoff modelling, hydrodynamic and morphological modelling of the Dinder river and its floodplain, with special focus on the Mayas wetlands. Moreover, this research is the first study to investigate the eco-hydrology of the DNP. It is expected that the results of the study will be beneficial to all stakeholders concerned and support decision-making processes for better management of water resources and ecosystem conservation in the area and possibly beyond.

Water is an essential element in the future of cities. It shapes cities' locations, form, ecology, prosperity and health. The changing nature of urbanisation, climate change, water scarcity, environmental values, globalisation and social justice mean that the models of provision of water services and infrastructure that have dominated for the past two centuries are increasingly infeasible. Conventional arrangements for understanding and managing water in cities are being subverted by a range of natural, technological, political, economic and social changes. The prognosis for water in cities remains unclear, and multiple visions and discourses are emerging to fill the space left by the certainty of nineteenth century urban water planning and engineering.This book documents a sample of those different trajectories, in terms of water transformations, option, services and politics. Water is a key element shaping urban form, economies and lifestyles, part of the ongoing transformation of cities. Cities are faced with a range of technical and policy options for future water systems. Water is an essential urban service, but models of provision remain highly contested with different visions for ownership of infrastructure, the scale of provision, and the level of service demanded by users. Water is a contentious political issue in the future of cities, serving different urban interests as power and water seem to flow in the same direction. Cities in Africa, Asia, Australia, Europe and South America provide case studies and emerging water challenges and responses. Comparison across different contexts demonstrates how the particular and the universal intersect in complex ways to generate new trajectories for urban water.

Kaya Barry, Maria Borovnik, Tim Edensor
R3,925 Discovery Miles 39 250 Ships in 12 - 17 working days

This book delves into the everyday spaces, diverse mobilities and affective potency of weather. It presents cutting-edge research into the multiplicity of weather phenomena and analyses the lived experiences of humans in conjunction with contemporary issues, notably climate change. The book considers how everyday experiences of weather in the mundane lives of people are linked to broader changes in weather patterns and climate change. Heat, dust, ice, snow, precipitation, sunlight, clouds, tides and fog are states of weather that impact on the ways in which humans become intertwined with landscapes. Our experiences with weather are diverse and ever-changing, and engaging with weather entangles humans with mobilities, materials and landscapes. This book thus explores affective and sensory resonances, drawing upon a variety of theoretical, empirical and creative material to investigate how weather is perceived in different social and cultural contexts. Key themes focus on the mobilities generated by weather, the affective and sensual potency of weather, and the diverse cultural forms and practices that exemplify how weather is historically, geographically and artistically represented. Offering a social and cultural understanding of weather events, this book contributes to a growing literature on weather across various disciplines, including human geography and cultural geography, and will thus appeal to students and scholars of geography, sociology, humanities, cultural studies and the arts.

Water utilities are the main instrument for countries to achieve universal service coverage. In pursuing universal service coverage, water utilities have turned to pro-poor water services to extend water services in low-income areas. This thesis discusses the use of pro-poor water services by water utilities in Kenya, with the intention of highlighting the dimensions of the approach that require attention of policy makers and practitioners when engaging with the concept. Based on the analysis of the technologies, financial and organisational arrangements associated with the pro-poor concept, this thesis shows that the use of pro-poor strategies allows water utilities to reduce the risks of servicing low-income areas while still claiming to fulfil their mandate of providing access to all in a commercially viable manner. The analysis also shows that rather than a decision of the water utility, the choice for pro-poor strategies emerges as the result of a consensus or compromise between the different actors that constitute the broader institutional environment in which water utilities operate. The thesis concludes that while pro-poor water services may serve the interests of water utilities and other stakeholders, in the absence of well-directed subsidies and proper monitoring they will not result in low-income households benefiting from more affordable and reliable access to water.

R1,086 Discovery Miles 10 860 Ships in 12 - 17 working days

Originally published in 1965 and with a second edition in 1970. Building upon the original two Madingley Hall seminars for teachers of non-university geography in 1965, this book presents an updated research picture of the 1970 transatlantic perspective. Answering the questions "What is happening in geography" and "What impact does this have on school geography", this provided a real link for students who were then making the increasingly difficult transition from school to university geography. Originally receiving a hostile reaction from British journals, the book's diagnosis and prognosis were a forerunner of developments in methodological changes of the discipline. This work collects a series of essays delineating geographic concepts in terms of the philosophic underpinnings, assessment of the geomorphic system, climatology, and social economic and historical changing trends. Techniques are reviewed including quantitative methods for geomorphology and social geography, fieldwork both in urban areas and land-use surveys, and finally in physical planning. Final analyses examine and contrast the teaching methods and courses in American and British High Schools, Colleges and Universities.

R1,394 Discovery Miles 13 940 Ships in 12 - 17 working days

Advances in high spatial resolution mapping capabilities and the new rules established by the Federal Aviation Administration in the United States for the operation of Small Unmanned Aircraft Systems (sUAS) have provided new opportunities to acquire aerial data at a lower cost and more safely versus other methods. A similar opening of the skies for sUAS applications is being allowed in countries across the world. Also, sUAS can access hazardous or inaccessible areas during disaster events and provide rapid response when needed. Applications of Small Unmanned Aircraft systems: Best Practices and Case Studies is the first book that brings together the best practices of sUAS applied to a broad range of issues in high spatial resolution mapping projects. Very few sUAS pilots have the knowledge of how the collected imagery is processed into value added mapping products that have commercial and/or academic import. Since the field of sUAS applications is just a few years old, this book covers the need for a compendium of case studies to guide the planning, data collection, and most importantly data processing and map error issues, with the range of sensors available to the user community. Written by experienced academics and professionals, this book serves as a guide on how to formulate sUAS based projects, from choice of a sUAS, flight planning for a particular application, sensors and data acquisition, data processing software, mapping software and use of the high spatial resolution maps produced for particular types of geospatial modeling. Features: Focus on sUAS based data acquisition and processing into map products Broad range of case studies by highly experienced academics Practical guidance on sUAS hardware, sensors, and software utilized Compilation of workflow insights from expert professors and professionals Relevant to academia, government, and industry Positional and thematic map accuracy, UAS curriculum development and workflow replicability issues This book would be an excellent text for upper-level undergraduate to graduate level sUAS mapping application courses. It is also invaluable as a reference for educators designing sUAS based curriculum as well as for potential sUAS users to assess the scope of mapping projects that can be done with this technology.

Groundwater and Climate Change - Multi-Level Law and Policy Perspectives (Paperback): Philippe Cullet, Raya Marina Stephan Groundwater and Climate Change - Multi-Level Law and Policy Perspectives (Paperback)
Philippe Cullet, Raya Marina Stephan
R1,226 Discovery Miles 12 260 Ships in 12 - 17 working days

This book undertakes a scholarly assessment of the state of the art of law and policy perspectives on groundwater and climate change at the international, regional and national levels. A particular focus is given to India, which is the largest user of groundwater in the world, and where groundwater is the primary source of water for domestic and agricultural uses. The extremely rapid rise in groundwater use in many Indian states has led to a growing groundwater crisis that they must address. The existing regulatory framework has not adapted to the challenges and fails to address any environmental concerns. On climate change, India has adopted a policy framework that makes the link with water, but no legislation has followed up to make the link operational. The subject matter of this book has been widely debated with regard to each of its main two components separately. Bringing these two domains together is what makes this book unique. The link between climate change and groundwater has been acknowledged to some extent, and there is growing interest in studying the impacts of climate change on (ground)water. Similarly, in water and environmental law and policy, increasing attention has been given to the study of climate change and groundwater legal and policy frameworks but generally separately. This book contributes to filling this knowledge gap by drawing on contributions from leading experts in the field of environmental and water law and policy who have been involved in climate change and/or groundwater research. The chapters in this book were originally published in a special issue of Water International.
