The fourth report in the Global Environment Outlook series provides a comprehensive, scientifically credible, policy-relevant and up-to-date assessment of, and outlook for, the state of the global environment. Environment for development is the GEO-4 underlying theme and the report pays special attention to the role and impact of the environment on human well-being as well as to the use of environmental valuation as a tool for decision-making. GEO-4's 2007 publication date marks the half-way point for the Millennium Development Goals, The environment, as well as being the subject of MDG 7, is also a thread that runs through all the goals. Includes Errata.

There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions. Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something. This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.

This volume provides an authoritative and comprehensive state-of-the-art review of hot desert terrains in all parts of the world, their geomaterials and influence on civil engineering site investigation, design and construction. It primarily covers conditions and materials in modern hot deserts, but there is also coverage of unmodified ancient desert soils that exhibit engineering behaviour similar to modern desert materials. Thorough and up-to-date guidance on modern field evaluation and ground investigation techniques in hot arid areas is provided, including reference to a new approach to the desert model and detailed specialised assessments of the latest methods for materials characterisation and testing. The volume is based on world-wide experience in hot desert terrain and draws upon the knowledge and expertise of the members of a Geological Society Engineering Group Working Party comprising practising geologists, geomorphologists and civil engineers with a wealth of varied, but complementary experience of working in hot deserts. It is an essential reference book for professionals, as well as a valuable textbook for students. It is written in a style that is accessible to the non-specialist. A comprehensive glossary is also included. The Geological Society of London. Founded in 1807, the Geological Society of London is the oldest geological society in the world, and one of the largest publishers in the Earth sciences. The Society publishes a wide range of high-quality peer-reviewed titles for academics and professionals working in the geosciences, and enjoys an enviable international reputation for the quality of its work.

The year 2007 could perhaps accurately be described as the year when climate change finally received the attention that this challenge deserves globally. Much of the information and knowledge that was created in this field during the year was the result of the findings of the Fourth - sessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC), which were disseminated on a large scale and reported extensively by the media. This was the result not only of a heightened interest on the part of the public on various aspects of climate change, but also because the IPCC itself proactively attempted to spread the findings of its AR4 to the public at large. The interest generated on the scientific realities of climate change was further enhanced by the award of the Nobel Peace Prize to the IPCC and former Vice President of the US, Al Gore. By taking this decision in favour of a leader who has done a great deal to create awareness on c- mate change, and a body that assesses all scientific aspects of climate change and disseminates the result of its findings, the Norwegian Nobel Committee has clearly drawn the link between climate change and peace in the world.

This book covers the wider aspects of the microbiology of hot desert soil ecosystems, compiling disparate information from a range of relevant desert soil microbial fields. The reader learns about microbial ecology of the more dominant and possibly most important desert habitats, detailing the phylogenetic and functional diversity of these different habitats as well as their potential role in desert ecosystem ecology. Particular attention is also given to microbial stress adaptation in hot desert soils. Furthermore, it is the first volume in this particular field to cover modern metagenomics technologies that can be applied to studies of all aspects of desert microbial communities. Additionally, the book explores viruses and viral communities, which are among the least studied (and little understood) components of desert soil microbial communities. Particular attention is also given to the roles of desert microbial communities in biogeochemical cycling of carbon, nitrogen and phosphorus. Through this book the reader discovers how desert microbiology has been at the forefront of Astrobiology and how it may be used conceptually in future terraforming strategies. Desert ecosystems are increasingly coming into focus given the impacts of climate change and desertification trends, making this volume particularly timely. Each of the chapters is authored by leading international researchers and is a must-read for microbial ecologists.

From endless sand dunes and prickly cacti to shimmering mirages and green oases, deserts evoke contradictory images in us. They are lands of desolation, but also of romance, of blistering Mojave heat and biting Gobi cold. Covering a quarter of the earth’s land mass and providing a home to half a billion people, they are both a physical reality and landscapes of the mind. The idea of the desert has long captured Western imagination, put on display in films and literature, but these portrayals often fail to capture the true scope and diversity of the people living there. Bridging the scientific and cultural gaps between perception and reality, The Desert celebrates our fascination with these arid lands and their inhabitants, as well as their importance both throughout history and in the world today. Covering an immense geographical range, Michael Welland wanders from the Sahara to the Atacama, depicting the often bizarre adaptations of plants and animals to these hostile environments. He also looks at these seemingly infertile landscapes in the context of their place in history—as the birthplaces not only of critical evolutionary adaptations, civilizations, and social progress, but also of ideologies. Telling the stories of the diverse peoples who call the desert home, he describes how people have survived there, their contributions to agricultural development, and their emphasis on water and its scarcity. He also delves into the allure of deserts and how they have been used in literature and film and their influence on fashion, art, and architecture. As Welland reveals, deserts may be difficult to define, but they play an active role in the evolution of our global climate and society at large, and their future is of the utmost importance. Entertaining, informative, and surprising, The Desert is an intriguing new look at these seemingly harsh and inhospitable landscapes.

Environmental and Human Security: Then and Now 1 2 ALAN D. HECHT AND P. H. LIOTTA * 1 U. S. Environmental Protection Agency Office of Research and Development 2 Pell Center for International Relations and Public Policy Salve Regina University 1. Nontraditional Threats to Security The events of September 11, 2001 have sharpened the debate over the meaning of being secure. Before 9/11 there were warnings in all parts of the world that social and environmental changes were occurring. While there was prosperity in North America and Western Europe, there was also increasing recognition that local and global effects of ecosystem degradation posed a serious threat. Trekking from Cairo to Cape Town thirty years after living in Africa as a young teacher, for example, travel writer Paul Theroux concluded that development in sub-Saharan Africa had failed to improve the quality of life for 300 million people: “Africa is materially more decrepit than it was when I first knew it—hungrier, poorer, less educated, more pessimistic, more corrupt, and you can’t tell the politicians from the witch-doctors” (2002). While scholars and historians will debate the causes of 9/11 for some time, one message is clear: An often dizzying array of nontraditional threats and complex vulnerabilities define security today. We must understand them, and deal with them, or suffer the consequences. Environmental security has always required att- tion to nontraditional threats linked closely with social and economic well-being.

Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Ciénegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today’s distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.

This is a summary of UNEP's activities in 2006. The main purpose of UNEP is to encourage international co-operation in preserving and protecting the environment. This objective is developed alongside other United Nations departments and international governments by addressing issues such as climate change and sustainable development challenges. Environmental issues also tie into poverty reduction and the general development strategies as set out in the Millennium Development Goals. The theme of this particular annual report is change; climate change; energy change, ecosystem change, and how such change, with impact on future generations.
