This open access book brings together research studies, developments, and application-related flash flood topics on wadi systems in arid regions. The major merit of this comprehensive book is its focus on research and technical papers as well as case study applications in different regions worldwide that cover many topics and answer several scientific questions. The book chapters comprehensively and significantly highlight different scientific research disciplines related to wadi flash floods, including climatology, hydrological models, new monitoring techniques, remote sensing techniques, field investigations, international collaboration projects, risk assessment and mitigation, sedimentation and sediment transport, and groundwater quality and quantity assessment and management. In this book, the contributing authors (engineers, researchers, and professionals) introduce their recent scientific findings to develop suitable, applicable, and innovative tools for forecasting, mitigation, and water management as well as society development under seven main research themes as follows: Part 1. Wadi Flash Flood Challenges and Strategies Part 2. Hydrometeorology and Climate Changes Part 3. Rainfall-Runoff Modeling and Approaches Part 4. Disaster Risk Reduction and Mitigation Part 5. Reservoir Sedimentation and Sediment Yield Part 6. Groundwater Management Part 7. Application and Case Studies The book includes selected high-quality papers from five series of the International Symposium on Flash Floods in Wadi Systems (ISFF) that were held in 2015, 2016, 2017, 2018, and 2020 in Japan, Egypt, Oman, Morocco, and Japan, respectively. These collections of chapters could provide valuable guidance and scientific content not only for academics, researchers, and students but also for decision-makers in the MENA region and worldwide.

Desertification, land degradation and other geological hazards have resulted from the remobilization of dune areas and climatic change. Recent developments in satellite images of deserts, orbital images of Mars and Venus, and oil and gas discoveries in ancient dunes, have significantly advanced our understanding of desert environments. "The Geomorphology of Desert Dunes" explores how desert dunes are formed, how they change and their environmental importance. Drawing on extensive research from the deserts of South Africa, North America, India, Northern Europe and Australia, the author analyses dune types, patterns, sand seas and sediments, and investigates dune dynamics and processes at different temporal and spatial scales. Investigating the role of climatic change, the author concludes that a better understanding of dune processes and dynamics is vital for effective and appropriate mitigation of environmental problems in arid regions.

The Integrated Urban Water Management (IUWM) is an emerging approach to managing the entire urban water cycle in an integrated way, which is key to achieving the sustainability of urban water resources and services. The IUWM incorporates: the systematic consideration of the various dimensions of water, including surface and groundwater resources, quality and quantity issues; the implication that while water is a system it is also a component which interacts with other systems; and the interrelationships between water and social and economic development. Integrated Urban Water Management: Arid and Semi-Arid Regions - the outcome of UNESCO's International Hydrological Programme project on the topic - examines the integrated management of water resources in urban settings, focusing on issues specific to arid and semi-arid regions and on what make them different from other regions. The urban water management system is considered herein as two integrated major entities; water supply management and water excess management. The first six chapters provide an overview of the various aspects of IUWM in arid and semi-arid regions, with emphasis on water supply technologies, such as artificial recharge, water transfers, desalination, and harvesting of rainfall. Water excess management is examined in the context of both the stormwater management system and the floodplain management system. Case studies from developed and developing countries are presented in order to emphasize the various needs and challenges of water management in urban environments in arid and semi-arid regions around the world.

Hotter and dryer than most parts of the world, the Middle East could soon see climate change exacerbate food and water shortages, aggravate social inequalities, and drive displacement and political destabilization. And as renewable energy eclipses fossil fuels, oil rich countries in the Middle East will see their wealth diminish. Amidst these imminent risks is a call to action for regional leaders. Could countries such as Saudi Arabia, Kuwait, and the United Arab Emirates harness the region's immense potential for solar energy and emerge as vanguards of global climate action? The Power of Deserts surveys regional climate models and identifies the potential impact on socioeconomic disparities, population movement, and political instability. Offering more than warning and fear, however, the book highlights a potentially brighter future-a recent shift across the Middle East toward renewable energy. With his deep knowledge of the region and knack for presenting scientific data with clarity, Dan Rabinowitz makes a sober yet surprisingly optimistic investigation of opportunity arising from a looming crisis.

A land of austerity and bounty, the Sonoran Desert is a place that captures imaginations and hearts. It is a place where barbs snag, thorns prick, and claws scratch. A place where lizards scramble and it's a book to walk with, a book to scribble in, and even a book to use as a cushion if the desert rock you tried to sit on was too sharp. A place where lizards scramble and pause, hawks hunt like wolves, and bobcats skulk in creosote. Both literary anthology and hands-on field guide, The Sonoran Desert is a groundbreaking book that melds art and science. It captures the stunning biodiversity of the world's most verdant desert through words and images. More than fifty poets and writers-including Christopher Cokinos, Alison Hawthorne Deming, Ken Lamberton, Eric Magrane, Jane Miller, Gary Paul Nabhan, Alberto Rios, Ofelia Zepeda, and many others-have composed responses to key species of this striking desert. Each creative contribution is joined by an illustration by award-winning artist Paul Mirocha and scientific information about the creature or plant authored by the book's editors. From the saguaro to the mountain lion, from the black-tailed jackrabbit to the mesquite, the species represented here have evoked compelling and creative responses from each contributor. Just as writers such as Edward Abbey and Ellen Meloy have memorialized the desert, this collection is sure to become a new classic, offering up the next generation of voices of this special and beautiful place, the Sonoran Desert.

The sand seas of Saudi Arabia, although well-known in literature, remain poorly explored scientifically. This is the first book to analyze, both quantitatively and qualitatively, the patterns, nature, and communities of the vegetation of the sand seas, using new techniques which the authors hope will prove adaptable for similar studies in other areas. The book covers such topics as the natural environment of the sand seas, vegetative paleohistory, and the importance of the sand seas as a recreational area.

The world's deserts are sufficiently large that, in theory, covering a fraction of their landmass with PV systems could generate many times the current primary global energy supply. The third book in the Energy from the Desert series examines the socio-economic, environmental and financial issues surrounding the use of Very Large Scale Photovoltaics (VLS-PV). It provides detailed coverage of technology and financing options (including recent and future trends in PV technology), potential social benefits such as desalination and agricultural development, and environmental and ecological impacts of systems and how these can be monitored, illustrated by case studies from the Sahara and Gobi Deserts. The concluding section consists of a roadmap outlining the options and opportunities for future implementation of VLS-PV. Building on the key concepts and case studies of previous volumes, this will be a key text for policy-makers and investors in the field.

A vividly illustrated work, the Atlas of the World's Deserts describes the hostile and extreme environments that cover more than a seventh of the world's surface. Yet, in spite of such harsh conditions, fauna and flora have developed and flourished, and humans have adapted to living in a seemingly inhospitable environment. The atlas examines in detail all aspects of the deserts, their geology, geography, history, culture, and biodiversity, from the Polar Regions to the Sahara and the Mojave Desert. Sidebars highlight particular aspects of the story of the deserts, such as the formation of sand dunes and the cave-dwelling quartz miners of central Australia. The numerous full color illustrations include spectacular, large-scale photographs that capture the stark beauty of the desert's color and light and original maps that illustrate the varying topography of the different regions. Each chapter concentrates on a specific characteristic of deserts including the process by which deserts are formed, the plants and animals that inhabit the desert, and the desert in modern times. Separating the chapters are unique atlas sections that contain detailed maps of the deserts of different continents along with commentary and facts particular to that specific desert. The Atlas of the World's Deserts is a vibrant and thorough portrait of the desert regions of the world and an excellent resource for exploring every feature of the desert ecosystem.

In semi arid and arid regions of the country, a vast land resource (39.54 m ha) is available which is underutilized, having good potential of expansion for quality production of several horticultural, medicinal, spices, ornamental and crops of economic importance. The horticulture can play vital role in diversification of these untapped natural resources. The development of arid horticulture is not very old; the published literature on many crops of economic importance and their multiplication is also scanty. Looking to prospects of such underutilized crop, its propagation methodology should be standardized for large scale plantation through availability of quality planting material. The work on production technology of underutilized arid horticultural crops in limited and scattered. Therefore, an effort was made to compile the work done so far in the field of multiplication of semi- arid and arid horticultural plants with special reference to Indian scenario in the form of a book to develop the knowledge base of all those involved in research and development of cold and hot arid lands. This book will be useful for the scientists, teachers, researchers, students, growers, policy makers and also for the personnel engaged in nursery management. The contributors of different s included in the book are well known personality in their field.

Arid and semi-arid areas are now facing a threefold holistic crisis: economic, food, and climate. What has emerged from these crises is the vital importance of inter-linkages among them on the one hand, and the missed opportunities in putting these pieces together on the other. This book has tried to explore these challenges though in-depth discussions of the individual. It is anticipated to inspire a forward looking debate that looks at the lessons from the past and points to actions for the future. Expertise views have been shared scientists and persons of eminence on the national and state level challenges with futuristic remedial approaches.

This book provides an understanding of desert environments, their climatic conditions, and unique physical beauty - using the five American deserts of the southwestern United States as an example. Through considerable research, sensitivity, and practical experience, the author provides insight into how built environments are designed and installed in order to cope with the harsh, unforgiving physiographic area.

Lack of water is the limiting factor for many household and community-based activities for millions of people living in dryland areas. Rural water supply programmes tend to focus on only two social aspects: improved access to domestic supply and improved sanitation. Less attention has been paid to how communities prefer to use water to develop their own livelihoods. This is due partly to the difficulties of abstracting sufficient reliable groundwater in dryland areas and partly to a misunderstanding of why wells and boreholes fail, which leads to a general belief that abstraction should be limited to domestic supply to conserve the resource. When more water is available, not only are basic drinking and washing needs satisfied but also other activities with a high economic value become feasible, such as small-scale irrigation, fruit orchards, livestock feedlots, small-scale dairy units, fish farming, brick-making, etc. Such diversification avoids over-reliance on rain-fed cropping of marginal lands.;This book aims to show how research in Southern Africa has shed light on why conventional wells and boreholes fail, on the potential of the groundwater resource to support production through improved siting and selection of more appropriate well designs and on the positive impacts and some problems that can emerge at productive water points. The findings are presented in a practical manner to encourage planners and practitioners in rural water supply to consider developing productive water points in drought-prone areas, and to provide the information they need to follow this through.

The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth's greatest desert-including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara's origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert's ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes-such as prolonged droughts-upon the Sahara's geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert's surprising past to reflect on its present, as well as its possible future.

Deserts are highly emblematic spaces: dry, barren, isolated. In literary and cinematic representations, they often betoken collapse and dystopia. Reading Aridity in Western American Literature offer readings of literature set in the US Southwest from ecocritical and new materialist perspectives. The volume explores the diverse epistemologies, histories, relationships, futures, and possibilities that emerge from the representation of American deserts in fiction, film, and literary art. The authors, as well, trace the social, cultural, economic, and biotic narratives that foreground deserts, and how these underscore the challenges of climate change, ecojustice, and human and non-human flourishing. As such, the volume rethinks what deserts are and provides a constructive lens for seeing deserts as more than blank spaces, rather as ecogeographies that challenge, critique, and urge collective ecojustice action.

Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9-11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18-20).

The inaction of nation states and international bodies has posed significant risks to the environment. By contrast, cities are sites of action and innovation. In Sustainability, Citizen Participation, and City Governance, contributors researching in the areas of law, urban planning, geography, and philosophy identify approaches for tackling many of the most challenging environmental problems facing cities today. Sustainability, Citizen Participation, and City Governance facilitates two strands of dialogue about climate change. First, it integrates legal perspectives into policy debates about urban sustainability and governance, from which law has typically stood apart. Second, it brings case studies from Quebec into a rare conversation with examples drawn from elsewhere in Canada. The collection proposes humane and inclusive processes for arriving at effective policy outcomes. Some chapters examine governance mechanisms that reconcile clashes of incommensurable values and resolve conflicts about collective interests. Other chapters provide platforms for social movements that have faced obstacles to communicating to a broad public. The collection's proposals respond to drastic changes in urban environments. Some changes are imminent. Others are upon us already. All threaten the present and future well-being of urban communities.

Many historians and political scientists argue that ties between Canada and Latin America have been weak and intermittent because of lack of mutual interest and common objectives. Has this record of diverging paths changed as Canada has attempted to expand its economic and diplomatic ties with the region? Has Canada become an imperialist power? Canada's Past and Future in Latin America investigates the historical origins of and more recent developments in Canadian foreign policy in the region. It offers a detailed evaluation of the Harper and Trudeau governments' approaches to Latin America, touching on political diplomacy, bilateral development cooperation, and civil society initiatives. Leading scholars of Canada-Latin America relations offer insights from unique perspectives on a range of issues, such as the impact of Canadian mining investment, security relations, democracy promotion, and the changing nature of Latin American migration to Canada. Drawing on archival research, field interviews, and primary sources, Canada's Past and Future in Latin America advances our understanding of Canadian engagement with the region and evaluates options for building stronger ties in the future.

Remote sensing is the study of a region from a distance, particularly from an airplane or a spacecraft. It is a tool that can be used in conjunction with other methods of research and investigation. This tool is especially applicable to the study of the deserts and arid lands of the Earth because of their immense size and their inaccessibility to detailed study by conventional means. In this book examples are given of the utility of aerial photographs and space images in the study of semi-arid, arid, and hyper-arid terrains. Emphasis is placed on the physical features and terrain types using examples from around the world. The authors I have called upon to prepare each chapter are renowned specialists whose contributions have received international recognition. To the general reader, this book is a review of our knowledge of the relatively dry parts of the Earth, their classification and varied features, their evolution in space and time, and their development potentials. To the specialist, it is a detailed account of the deserts and arid lands, not only in North America, but also their relatively unknown counterparts in North Africa, Australia, China, India, and Arabia.

Logan and his friend Benedict run into the wrong guy at the library--literally. When Logan slams into the reference guy in the basement and gives hima little lip, Logan gets punished, really and truly punished. He has three days to complete three tasks before Professor Wordsworth will lift the magical punishment that keeps getting Logan in even more trouble.

This book chronicles and explains the role of suburbs in North American cities since the mid-twentieth century. Examining fifteen case studies from New York to Vancouver, Atlanta to Chicago, Montreal to Phoenix, The Life of North American Suburbs traces the insightful connection between the evolution of suburbs and the cultural dynamics of modern society. Suburbs are uniquely significant spaces: their creation and evolution reflect the shifting demographics, race relations, modes of production, cultural fabric, and class structures of society at large. The case studies investigate the place of suburbs within their wider metropolitan constellations: the crucial role they play in the cultural, economic, political, and spatial organization of the city. Together, the chapters paint a compelling portrait of North American cities and their dynamic suburban landscapes.

This book provides a rich and illuminating account of the peripheries of urban, regional, and transnational development in South Korea. Engaging with the ideas of "core location," a term coined by Baik Young-seo, and "Asia as method," a concept with a century-old intellectual lineage in East Asia, each chapter in the volume discusses the ways in which a place can be studied in an increasingly globalized world. Examining cases set in the Jeju English Education City, anti-poverty and community activist sites, rural areas home to large numbers of migrant women, and Korea's Chinatowns, greenbelts, and textile factories, the collection develops a relational understanding of a place as a constellation of local and global forces and processes that interact and contradict in particular ways. Each chapter also explores multiple modes of urban marginality and discusses how understanding them shapes the methods of academic praxis for social justice causes and decolonialized scholarship. This book is the outcome of several years of interdisciplinary collaborations and dialogues among scholars based in geography, architecture, anthropology, and urban politics.
