Changing Desert Environments


Book Description

Many people have heard of Earth's largest deserts: the Sahara in northern Africa, the Gobi in east central Asia, and the Arabian in the Arabian Peninsula. However, some people may not know that these deserts weren't always so big. Desertification is the process by which natural or human causes turn previously productive land into desert areas. This book explores the different causes of desertification and the ways even longtime desert lands can change. Fact boxes and sidebars provide readers with additional information relating to the main text.




Geomorphology of Desert Environments


Book Description

Over the last twenty years there has been a major expansion of knowledge in the field of landforms and landforming processes of deserts. This advanced-level book provides a benchmark for the current state of science, and is written by an international team of authors who are acknowledged experts in their fields.




Deserts and Desert Environments


Book Description

Taking a global perspective, this book provides a concise overviewof drylands, including their physical, biological, temporal, andhuman components. Examines the physical systems occurring in desert environments,including climate, hydrology, past and present lakes, weathering,hillslopes, geomorphic surfaces, water as a geomorphic agent, andaeolian processes Offers an accessible introduction to the physical, biological,temporal, and human components of drylands Investigates the nature, environmental requirements, andessential geomorphic roles of plants and animals in this stressfulbiological environment Highlights the impact of human population growth on climate,desertification, water resources, and dust storm activity Includes an examination of surface/atmosphere interactions andthe impact of ENSO events.




Ecology of Desert Systems


Book Description

Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. - Highlights the complexity of global desert systems in a clear, concise way - Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change - Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems




Climate Change in Deserts


Book Description

A synthesis of the environmental and climatic history of every major desert and desert margin, for researchers and advanced students.




The Power of Deserts


Book Description

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.




Understanding the Changing Planet


Book Description

From the oceans to continental heartlands, human activities have altered the physical characteristics of Earth's surface. With Earth's population projected to peak at 8 to 12 billion people by 2050 and the additional stress of climate change, it is more important than ever to understand how and where these changes are happening. Innovation in the geographical sciences has the potential to advance knowledge of place-based environmental change, sustainability, and the impacts of a rapidly changing economy and society. Understanding the Changing Planet outlines eleven strategic directions to focus research and leverage new technologies to harness the potential that the geographical sciences offer.




Geomorphology of Desert Environments


Book Description

About one-third of the Earth’s land surface experiences a desert climate, and this area supports approximately 15% of the planet’s population. This percentage continues to grow, and with this growth comes the need to acquire and apply an understanding of desert geomorphology. Such an understanding is vital in managing scarce and fragile resources and in mitigating natural hazards. This authoritative reference book is comprehensive in its coverage of the geomorphology of desert environments, and is arranged thematically. It begins with an overview of global deserts, proceeds through treatments of weathering, hillslopes, rivers, piedmonts, lake basins, and aeolian surfaces, and concludes with a discussion of the role of climatic change. Written by a team of international authors, all of whom are active in the field, the chapters cover the spectrum of desert geomorphology.




Geomorphology and Global Environmental Change


Book Description

A statement from the world's leading geomorphologists on the state of, and potential changes to, the environment.




Quaternary Environmental Change in Southern Africa


Book Description

Ongoing climate change necessitates advances in our understanding of the interrelationships between climate, landscape-shaping processes and human activity over long time periods, especially in areas that are already climatically stressed. This volume presents new ideas on macroscale landscape evolution; mountain, fluvial and aeolian processes; and environments in southern Africa, a key region in the story of human evolution during the last two million years. Interdisciplinary in scope, it brings together an international team of experts to synthesise the latest research and understanding of landscape-human relationships in this region. It incorporates results from the emerging fields of geoarchaeology and cultural landscapes and utilises the latest data and analytical techniques. A key reference for researchers studying hominid evolution, geoarchaeology and environmental change, it provides a benchmark study of southern African landscape evolution during the Quaternary. It will also appeal to professionals and policymakers with interests in future human-landscape evolution in southern Africa.
