Conserving Dryland Biodiversity

"This book Drylands: Biodiversity, Conservation and Management, edited by Victor R. Squires, Mahesh K. Gaur and Salah Attia Ismail, fills a gap in the literature admirably. It gets away from 'species lists' and designation of species and habitats as 'endangered' or 'at risk'. Instead, it opens up discussion on a range of issues relating to the important matters of biodiversity, land management and efforts at conservation (wise use) of natural resources that support an area's biodiversity. Dryland ecologists, land use change specialists, policy makers from UN agencies or from bilateral and multilateral donors and other natural resource management agencies will find the book very useful. It is also a valuable reference book for university students in ecology, geography, environmental studies and development studies in general. Key points: Provides a synoptic overview of the current problems and prospects for biodiversity conservation in a changing world based on a focus on selected ecosystems across Africa, Asia and the Middle East: Discusses the path forward to maintain and improve dryland ecosystems, conserve biodiversity and achieve land protection 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-dominated regions on all continents except Antarctica. Global change is more than just climate change. The shift to the market economy and demographic factors (population growth, urbanization and resettlement) receive attention here. The implications of change (including an analysis of the drivers of change) and the role of humans as agents of these changes are canvassed. Chapters by leading experts who live and work in lands focus on examples that are drawn from a number of sources including previously unpublished studies. The key purpose is to provide an up to date and in-depth global overview of drylands and give readers insights into the status of these vulnerable biomes and to alert readers to the consequences of a loss of biodiversity to the tens of millions of people, their livestock and the myriad of plants and animals that make up dryland ecosystems across the globe. Maintenance of biodiversity ensures the continued flow of ecosystems' goods and services on which most of us depend!"--

On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.

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.

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.

Limits to expansion of protected area systems underline the importance of seeking new ways to conserve biodiversity. The twelve case studies ranging from the High Andes to Viet Nam support the view that certain traditional agricultural and pastoral systems can succeed in attaining a sustainable level of production while at the same time maintaining both a high level of biodiversity and most functional aspects of the ecosystems.

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.
