Arid and Semi-Arid Environments focuses upon major themes in the study of desert landscapes, processes and landforms. The book considers the physical causes of aridity, the desert hydrological cycle and the problems of water supply. Particular attention is paid to desert ecosystems and how they are related to aridity. A detailed study is made of the wide range of landforms which are unique to desert areas and how they were formed. Evidence in the landscape of past climates is examined in relation to the current debate on desertification.

This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions. The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors’ synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

Groundwater Modelling in Arid and Semi-Arid Areas

Author: Howard S. Wheater,Simon A. Mathias,Xin Li

Publisher: Cambridge University Press

ISBN: 1139489720

Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.

Ecology of Desert Systems

Author: Walter G. Whitford

Publisher: Elsevier

ISBN: 9780080504995

Category: Science

Page: 343

View: 8144

Conventional wisdom considers deserts stark, harsh regions that support few living things. Most people also believe that water alone makes the desert bloom. Ecology of Desert Systems challenges these conventional views. This volume explores a broad range of topics of interest to ecosystem, population, community, and physiological ecologists. Climate, weather patterns, geomorphology, and wind and water processes are examined as variables that affect the distribution of biota through fundamental ecosystem processes. Descriptions of morphological, behavioral, and physiological adaptations of desert biota illuminate, through the lens of patch dynamics, principles for understanding observed patterns of primary production, nutrient cycling, and the effects of consumers. Desertification, and the techniques for monitoring and quantifying it, is examined within the framework of desert ecosystem patterns and processes. * Focuses on the interactions of climate, soil, and biota along a spectrum of spatial and temporal scales * Details the role of animals in desert ecosystems and landscape processes * Examines watershed scale processes, the ecology of ephemeral lakes, and the ecological changes identified with desertification * Outlines the fundamental concepts relevant to sustainable development of arid lands

Management of Semi-Arid Ecosystems

Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation. This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.

Rural Settlement and the Urban Impact on the Countryside

Author: Michael Hill

Publisher: Hodder Murray

ISBN: 9780340800287

Category: Education

Page: 154

View: 8039

Providing a wealth of information and relevant new case study material, Rural Settlement and Urban Impact on the Countryside encourages students to focus in on the highly topical geographical issues that have changed the countryside through urbanisation and counter-urbanisation. Geographical influences upon settlement location, hierarchy and morphology are studied in relation to the context of continuity and change. Economic conditions which lead to rural depopuoation are considered as are those that have led to the repopulation of some rural areas. The impact of the current cirsis in the countryside and the concept of the 'post-rural' society are also examined in relation to rural settlement. The text is illustrated with examples and case studies from Britain, Italy and a number of LEDCs. Applicable to AQA, OCR and Edexcel exam boards, this book is ideal for any student studying this topic.

Steppes—semi-arid biomes dominated by forbs, grasses, and grass-like species, and characterized by extremes of cold and heat—occupy enormous areas on four continents. Yet these ecosystems are among the least studied on our planet. Given that the birth and evolution of human beings have been so intimately interwoven with steppe regions, it is amazing that so few attempts have been made to compare and quantify the features of these regions. In this ground-breaking volume, five leading voices in horticulture—all staff members of Denver Botanic Gardens—examine the plants, climate, geology, and geography of the world’s steppes: central Asia, central and intermountain North America, Patagonia, and South Africa. Drawing upon their first-hand experience, the writers illuminate the distinctive features of each region, with a particular emphasis on the striking similarities between their floras. Each chapter includes a primer of species of horticultural interest—a rich resource for readers with an interest in steppe plants.
