Arid Land Ecosystems: Volume 2, Structure, Functioning and Management by D. W. Goodall,R. A. Perry,K. M. W. Howes Pdf
This volume was first published in 1981. The history of man's use of arid lands is a sad record of deterioration of the natural resource base and of low and declining living standards for the 300 million people who live in them. One prerequisite to meeting the challenge of reversing the deterioration and of raising living standards is a sound knowledge of the natural ecosystems.

A Guide for Desert and Dryland Restoration by David A. Bainbridge Pdf
Dryland degradation and desertification now affect almost a billion people around the world. Tragically, the biological resources and productivity of millions of acres of land are lost to desertification each year because people remain unaware of strategies and techniques that could improve yields, reduce risk, and begin healing the world's deserts. A Guide for Desert and Dryland Restoration is the first book to offer practical, field-tested solutions to this critical problem. Author David Bainbridge has spent more than 25 years actively involved in restoring lands across the American Southwest. A Guide for Desert and Dryland Restoration presents the results of his years of fieldwork, as well as research and experience from scientists and practitioners around the globe. The book discusses the ecology of desert plants, explores the causes of desertification and land abuse, and outlines the processes and procedures needed to evaluate, plan, implement, and monitor desert restoration projects. It sets forth economical and practical field-tested solutions for understanding site characteristics, selecting and growing plants, and ensuring that they survive with a minimal amount of water and care. Each chapter represents a guide to a critical topic for environmental restoration; extensive photographs, diagrams and drawings give detailed information for immediate application, and additional resources are included in appendixes. A Guide for Desert and Dryland Restoration is the first comprehensive book focused on restoring arid regions, and clearly demonstrates that arid lands can be successfully rehabilitated. In addition to restorationists, the book will be an invaluable resource for anyone working in arid lands, including farmers, ranchers, gardeners, landscapers, outdoor recreation professionals, and activists.
An argument that the perception of arid lands as wastelands is politically motivated and that these landscapes are variable, biodiverse ecosystems, whose inhabitants must be empowered. Deserts are commonly imagined as barren, defiled, worthless places, wastelands in need of development. This understanding has fueled extensive anti-desertification efforts—a multimillion-dollar global campaign driven by perceptions of a looming crisis. In this book, Diana Davis argues that estimates of desertification have been significantly exaggerated and that deserts and drylands—which constitute about 41% of the earth's landmass—are actually resilient and biodiverse environments in which a great many indigenous people have long lived sustainably. Meanwhile, contemporary arid lands development programs and anti-desertification efforts have met with little success. As Davis explains, these environments are not governed by the equilibrium ecological dynamics that apply in most other regions. Davis shows that our notion of the arid lands as wastelands derives largely from politically motivated Anglo-European colonial assumptions that these regions had been laid waste by “traditional” uses of the land. Unfortunately, such assumptions still frequently inform policy. Drawing on political ecology and environmental history, Davis traces changes in our understanding of deserts, from the benign views of the classical era to Christian associations of the desert with sinful activities to later (neo)colonial assumptions of destruction. She further explains how our thinking about deserts is problematically related to our conceptions of forests and desiccation. Davis concludes that a new understanding of the arid lands as healthy, natural, but variable ecosystems that do not necessarily need improvement or development will facilitate a more sustainable future for the world's magnificent drylands.
Management of Problem Soils in Arid Ecosystems by A. Monem Balba Pdf
Management of Problem Soils in Arid Ecosystems examines the challenges of managing soils in arid and semiarid regions. These soils contain low organic matter, are not leached, and accumulate lime, gypsum, and/or soluble salts, requiring special management and practices. This book discusses how to identify problems, reclaim the soils, and then use them efficiently and economically. Water management and desertification in these areas are also discussed. It contains extensive references as well as 40 tables and illustrations.
Reclamation of Arid Lands by Mohammad Jafari,Ali Tavili,Fatemeh Panahi,Ehsan Zandi Esfahan,Majid Ghorbani Pdf
This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.
Climate Change and Its Impact on Ecosystem Services and Biodiversity in Arid and Semi-Arid Zones by Karmaoui, Ahmed Pdf
Ecosystems provide services that are crucial and beneficial to the human population. The management and conservation of these services can assure the wellbeing of the local population. Climate Change and Its Impact on Ecosystem Services and Biodiversity in Arid and Semi-Arid Zones is an essential reference source that studies the effects of climate change on biodiversity and ecosystem services in dry regions and examines various strategic local, national, and international policy developments to help overcome these impacts. Featuring research on topics such as poverty reduction, climate change, and adaption policies, this book is ideally designed for environmentalists, policymakers, government officials, academicians, researchers, and technology developers who want to improve their understanding of climate change impact, vulnerability, and sustainability, and the strategic role of adaptation and mitigation.

Biodiversity in Drylands by Moshe Shachak,James R. Gosz,Stewart T. A. Pickett,Avi Perevolotsky Pdf
Biodiversity in Drylands, the first internationally based synthesis volume in the Long-Term Ecological Research (LTER) Network Series, unifies the concepts of species and landscape diversity with respect to deserts. Within this framework, the book treats several emerging themes, among them: � how animal biodiversity can be supported in deserts � diversity's relation to habitat structure, environmental variability, and species interactions � the relation between spatial scale and diversity � how to use a landscape simulation model to understand diversity � microbial contributions to biodiversity in deserts � species diversity and ecosystem processes � resource partitioning and biodiversity in fractal environments � effects of grazing on biodiversity � reconciliation ecology and the future of conservation management In the face of global change, integration is crucial for dealing with the problem of sustaining biodiversity. This book promises to be a vital resource for students, researchers, and managers interested in integrative species, resource, and landscape diversities.
Extractive Industries in Arid and Semi-arid Zones by Joachim Gratzfeld Pdf
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.
Dryland Ecohydrology by Paolo D'Odorico,Amilcare Porporato Pdf
Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.
