Book Description
This volume summarizes our current understanding of biological soil crusts (biocrusts), which are omnipresent in dryland regions. Since they cover the soil surface, they influence, or even control, all surface exchange processes. Being one of the oldest terrestrial communities, biocrusts comprise a high diversity of cyanobacteria, algae, lichens and bryophytes together with uncounted bacteria, and fungi. The authors show that biocrusts are an integral part of dryland ecosystems, stabilizing soils, influencing plant germination and growth, and playing a key role in carbon, nitrogen and water cycling. Initial attempts have been made to use biocrusts as models in ecological theory. On the other hand, biocrusts are endangered by local disruptions and global change, highlighting the need for enhanced recovery methods. This book offers a comprehensive overview of the fascinating field of biocrust research, making it indispensable not only for scientists in this area, but also for land managers, policy makers, and anyone interested in the environment.

Book Description
Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta

Book Description
In the name of agriculture, urban growth, and disease control, humans have drained, filled, or otherwise destroyed nearly 87 percent of the world’s wetlands over the past three centuries. Unintended consequences include biodiversity loss, poor water quality, and the erosion of cultural sites, and only in the past few decades have wetlands been widely recognized as worth preserving. Emily O’Gorman asks, What has counted as a wetland, for whom, and with what consequences? Using the Murray-Darling Basin—a massive river system in eastern Australia that includes over 30,000 wetland areas—as a case study and drawing on archival research and original interviews, O’Gorman examines how people and animals have shaped wetlands from the late nineteenth century to today. She illuminates deeper dynamics by relating how Aboriginal peoples acted then and now as custodians of the landscape, despite the policies of the Australian government; how the movements of water birds affected farmers; and how mosquitoes have defied efforts to fully understand, let alone control, them. Situating the region’s history within global environmental humanities conversations, O’Gorman argues that we need to understand wetlands as socioecological landscapes in order to create new kinds of relationships with and futures for these places.

Book Description
Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.

Book Description
The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.

Book Description
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.

Book Description
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.

Book Description
This study presents authentic data compiled from field experiments and investigations, and provides a point of reference for any future changes associated with anthropogenic activity in semiarid ecosystems. Three years of continuous and rigorous empirical research on biodiversity (from phytoplankton to higher plants and from zooplankton to higher animals – all flora and fauna) in India’s semiarid region have culminated in this work. Though there are many studies available on issues related to biodiversity, the majority cover either specific groups of plants or groups of animals; with the exception of this book, studies that include all flora and fauna including the phyto- and zooplanktons in a given ecosystem are not readily available. Further, the book focuses on an extremely important topic, firstly because semiarid landscapes are highly vulnerable to climate change, and secondly because other developmental activities will be undertaken in the region in an effort to meet its energy requirements. As such, the results of the current study will provide a standard protocol for subsequent monitoring and mapping of biodiversity for conservation and management. The book explores, quantifies and surveys plant and animal species from aquatic and terrestrial ecosystems, assessing and quantitatively analyzing the diversity indices of different vegetation strata. Further, it investigates the conservation status of each species (flora and fauna) in keeping with IUCN categories. The study also examines landscape dynamics using RS and GIS for vegetation analysis, and discusses traditional ecological knowledge related to the use, conservation and management of biodiversity. As such, it offers a unique and valuable resource not only for researchers from the environmental/ecological sciences but also for conservationists and policymakers.
