This book gathers contributions discussing climate change in Egypt from an agricultural perspective. Written by leading experts, it presents state-of-the-art insights and the latest research developments in light of the most recent IPCC report. Focusing on identifying the specific phenomena that affect climate change in Egypt, the book also addresses the effects of climate change in Egypt, particularly examining the quality and quantity of water resources as well as the socio-economic impacts of climate change on agricultural activities. Furthermore, it explores alternative solutions to support agriculture and food security and raises awareness of adaptation and protection as the key to adapting to the risks posed by climate change. Covering the four fundamental pillars of climate change: food security, availability, access and stability, this book is a valuable resource for stakeholders involved in achieving the 2030 sustainable development goals in Egypt and all countries with similar climatic conditions. It is also a unique source of information and updates on climate change impacts for graduates, researchers, policy planners, and decision-makers.
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.
This book is a research monograph summarizing recent advances related to the molecular structure of water and ice, and it is based on the latest spectroscopic data available. A special focus is given to radio- and microwave frequency regions. Within the five interconnected chapters, the author reviews the electromagnetic waves interaction with water, ice, and moist substances, discussing the microscopic mechanisms behind the dielectric responses. Well-established classic views concerning the structure of water and ice are considered along with new approaches related to atomic and molecular dynamics. Particular attention is given to nanofluidics, atmospheric science, and electrochemistry. The mathematical apparatus, based on diverse approaches employed in condensed matter physics, is widely used and allows the reader to quantitatively describe the electrodynamic response of water and ice in both bulk and confined states. This book is intended for a wide audience covering physicists, electrochemists, geophysicists, engineers, biophysicists, and general scientists who work on the electromagnetic radiation interaction with water and moist substances.
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.
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.
This book brings together contributions from groundwater researchers and scientists on underground water resources in Egypt's deserts. The aquifers' quantity and quality are evaluated in many regions of the Egyptian deserts using established methods that can be effectively employed to investigate the potential for sustainable development in Egypt and similarly arid countries. The water resources in Egypt's deserts are subject to deterioration, mainly by land salinization and water deficiency. This book presents the best management practices, water quantity and quality, and optimal and sustainable usage of available groundwater. The book offers a unique guide for all readers interested in groundwater, modeling, and assessment for sustainable development in Egypt and countries with similar weather and water conditions.
This volume provides in-depth coverage of the latest in remote sensing of hydrological extremes: both floods and droughts. The book is divided into two distinct sections - floods and droughts - and offers a variety of techniques for monitoring each. With rapid advances in computer modelling and observing systems, floods and droughts are studied with greater precision today than ever before. Land surface models, especially over the entire Continental United States, can map the hydrological cycle at kilometre and sub-kilometre scales. In the case of smaller areas there is even higher spatial resolution and the only limiting factor is the resolution of input data. In-situ sensors are automated and the data is directly relayed to the world wide web for many hydrological variables such as precipitation, soil moisture, surface temperature and heat fluxes. In addition, satellite remote sensing has advanced to providing twice a day repeat observations at kilometre to ten-kilometre spatial scales. We are at a critical juncture in the study of hydrological extremes, and the GPM and SMAP missions as well as the MODIS and GRACE sensors give us more tools and data than were ever available before. A global variety of chapter authors provides wide-ranging perspectives and case studies that will make this book an indispensable resource for researchers, engineers, and even emergency management and insurance professionals who study and/or manage hydrological extremes.
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.

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.
Originally published in 1973. This collection of essays looks at the 'quantitative revolution' and the 'new geography' by some of the geographers who had a significant part in those innovations and looks ahead to further developments. The views in the chapters are diverse and offer a fascinating glimpse of the discipline of geography as the subject was undergoing such change and becoming more socially committed. They cover theory, spatial-systems theory, forecasting, human ecology and climatology alongside the teaching of the subject. The concerns of the contemporary geographer come across and are of interest today as these areas have developed still more.

The book focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.
Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.
This book provides an overview of ninety key concepts which often trouble those who are new to researching within the social sciences. It covers theories of knowledge, methodologies and methods. Each entry offers a definition of a concept, shows how researchers have used that concept in their research and discusses difficulties that the concept presents. The book supports those undertaking their own social research projects by providing detailed critical commentary on key concepts in a particularly accessible way. In exploring these concepts, a wide range of research reports across many different fields are described. These include not only classic accounts, but also a broad selection of recent studies, some written by new researchers. The book will be useful for higher-education students carrying out projects within social science faculties at the end of their first degree or during a master's programme, though it will also be helpful for those undertaking doctoral research, and some entries have been written with the production of a thesis in mind. This second edition of Research Methods: The Key Concepts provides a more comprehensive and up-to-date coverage, as old entries have been updated and 19 new entries added. It helps new researchers to navigate the changing landscape of social research by recognising a) the changes in the ways researchers are thinking about knowledge and acquiring knowledge, b) the increasing use of digital tools to collect data, and c) the desire many contemporary researchers feel to promote social justice through their research. |
