The Future of Arid Lands, edited by Gilbert White and published in 1956, comprised papers delivered at the "International Arid Lands Meetings" held in New Mexico in 1955. At these meetings, experts considered the major issues then confronting the world’s arid lands and developed a research agenda to address these issues. This book reexamines this earlier work and explores changes in the science and management of arid lands over the past 50 years within their historical contexts.

Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.

International voices fill the pages of Water and Sustainability in Arid Regions, forming an original scientific exploration of current water research and management issues. In arid regions, agriculture that is ill-adapted to the environment, accelerated urbanization, poverty, and increasing pollution challenge access to and uses of water. Understanding these issues requires incorporating findings from both the physical and social sciences at different temporal and spatial scales. The chapters in this book were written by hydrologists, remote sensing specialists, ecologists, historians, economists, political scientists, architects, archaeologists, and other experts who live in and study arid lands. The authors present updates, overviews, and analyses of water challenges these areas have faced and are striving to address, from salinization in the fabled Taklimakan Desert in China to land degradation in the northern Mediterranean to groundwater over-exploitation in the southwestern United States. The book also examines desertification, remote sensing, qanat systems, architecture, arsenic contamination, and other case studies from Iran, the Maghreb region, Argentina and Chile, and Mexico. From this conceptual mosaic of comparative perspectives and research methods emerges a strong assumption: an interdisciplinary approach that combines physical and social sciences is the first step toward globally and comprehensively addressing water and sustainability."This book is a valuable and welcome contribution to the discussion of water and sustainable development. Through the collection of chapters, the book clearly illustrates the contemporary diversity of approaches to water scarcity and presents pertinent and new research findings that readers generally do not find compiled together. The result is a highly relevant, accessible, and timely resource that is unique in its international and interdisciplinary content. This is a must-read for anyone working on environmental and sustainability issues in arid lands."André Mariotti, University Pierre et Marie Curie, and INSU - CNRS (National Institute for Earth Sciences and Astronomy-National Center for Scientific Research/Centre National de la Recherche Scientifique), France "Anyone who reads this book will find himself or herself contemplating the need to rethink how we approach the issue of water and sustainability in arid lands. Drawing on the expertise of both physical and social scientists, the chapters taken as a whole present global, historic, and current perspectives on water scarcity in a multi-layered way that rarely has been done before."

The Future of Arid Lands, edited by Gilbert White and published in 1956, comprised papers delivered at the "International Arid Lands Meetings" held in New Mexico in 1955. At these meetings, sponsored by UNESCO and the American Association for the Advancement of Science, experts considered the major issues then confronting the world’s arid lands and developed a research agenda to address these issues. The Future of Arid Lands – Revisited, commissioned by UNESCO in 2005, reexamines this earlier work. Written by researchers from the University of Arizona, this volume first looks at the state of science in 1956 and attendant contemporary views of arid lands development. It then considers how scientific understanding of the processes governing arid lands has since evolved, before extracting lessons from these comparisons that might guide current and future arid land managers and speculating on what the future might hold for arid lands. Reflecting the shift in drylands thinking from a piecemeal or a ‘magic bullet’ approach to a systems-based approach that considers people as integral to solving problems, this volume will appeal not just to land managers, but to everyone involved in environmental issues who wishes to gain a better understanding of the state of arid lands science today.

This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (population growth, urbanization and re-settlement), receive attention here. Land use change specialists, policy makers and natural resource management agencies will find the book very useful. Chapters focus on examples that are drawn from a number of sources including previously unpublished studies on the impact of climate change, markets and economics on pastoralist and dryland farming households. The key focus is to provide readers with insights into the real world implications of change (including an analysis of the drivers of change) on these vulnerable groups within dryland societies. The role of humans as agents of these changes is canvassed. A regional analysis of the world's drylands is also performed including those in Australia, Argentina, India, North America, China, North Africa, Central Asia and Southern Africa.

The first book to chronicle how innovation in laboratory designs for botanical research energized the emergence of physiological plant ecology as a vibrant subdiscipline Laboratory innovation since the mid-twentieth century has powered advances in the study of plant adaptation, evolution, and ecosystem function. The phytotron, an integrated complex of controlled-environment greenhouse and laboratory spaces, was invented by Frits W. Went at the California Institute of Technology in the 1950s, setting off a worldwide laboratory movement, and transforming the plant sciences. Sharon Kingsland explores this revolution through a comparative study of work in the United States, France, Australia, Israel, the USSR, and Hungary--in the latter two, offering new interpretations of the response to Lysenkoism in Communist states. These advances in botanical research energized physiological plant ecology. Case studies explore the development of phytotron spin-offs such as mobile laboratories, rhizotrons, and ecotrons. Scientific problems include the significance of plant emissions of volatile organic compounds, symbiosis between plants and soil fungi, and the discovery of new pathways for photosynthesis as an adaptation to hot, dry climates. The advancement of knowledge through synthesis is a running theme: linking disciplines, combining laboratory and field research, and moving across ecological scales from leaf to ecosystem. The book also charts the history of modern scientific responses to the emerging crisis of food insecurity in the era of global warming.
