Book Description
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.

Book Description
This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.

Book Description
The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.

Book Description
Offering a cross-country examination and comparison of drought awareness and experience, this book shows how scientists, water managers, and policy makers approach drought and water scarcity in arid and semi-arid regions of Spain, Mexico, Australia, South Africa and the United States.

Book Description
The natural scarcity of water in arid and semiarid regions, aggravated by man-made factors, makes it difficult to achieve a reliable water resources supply. Communities in these areas pay the price for thousands of years of water manipulation. Presenting important insight into the complexities of arid region hydrology, Engineering Hydrology of Arid

Book Description
Based on four decades of research by Professor Andrew Goudie, this volume provides a state-of-the-art synthesis of our understanding of desert geomorphology. It presents a truly international perspective, with examples from all over the world. Extensively referenced and illustrated, it covers such topics as the importance of past climatic changes, the variability of different desert environments, rock breakdown, wind erosion and dust storm generation, sand dunes, fluvial and slope forms and processes, the role of the applied geomorphologist in desert development and conservation, and the Earth as an analogue for other planetary bodies. This book is destined to become the classic volume on arid and semi-arid geomorphology for advanced students and researchers in physical geography, geomorphology, Earth science, sedimentology, environmental science and archaeology.

Book Description
This publication aims to contribute to planning and management approaches that minimize land degradation and desertification in arid and semi-arid zones as a result of extractive industries operations. Both operational and policy guidance are included to help those government departments responsible for the licensing, planning and monitoring of extractive industries activities to take account of environment and development issues in their decision-making.

Book Description
Water deficiency in many arid and semi-arid regions in Southern Europe is becoming a major constraint for economic welfare and sustainable regional development. These regions are characterised by high spatial and temporal imbalances of water demand and supply, seasonal water uses, inadequate water resources and poor institutional water management. The aim of this book is to formulate appropriate strategies and guidelines for water management necessary for the formulation and implementation of integrated sustainable management of water resources. Lessons are learned from various case studies, which examine competing water use patterns, compare governance structures and how these have evolved in response to scarcity, and structural and non-structural instruments to address water deficiency. Water Management in Arid and Semi-Arid Regions will appeal to policymakers in relevant countries as well as to scholars and researchers of environmental studies and economics.

Book Description
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.

Book Description
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.
