Livestock biodiversity is integral to our culture, history, environment, economy and, most importantly, our future. Thousands of livestock breeds, from relatively small genetic pools, have evolved over time to suit particular environments and farming systems. This is both the result of natural processes and of human needs for specialized livestock – as our knowledge of genetics continues to increase we achieve a greater understanding of how this biodiversity evolved. This book offers a detailed and comprehensive overview of livestock biodiversity. It explores the history behind it, shows how livestock biodiversity can be utilized as animal genetic resources through breed development and by crossbreeding, examines the state of world livestock biodiversity today, and emphasizes the importance of conserving and developing the biodiversity of livestock. Special consideration is given to: • How livestock biodiversity arose and is maintained in relation to human society • How it can be used in sustainable agricultural development • How it can be conserved for the benefit of present and future generations • Why conservation biologists, as well as agriculturists, should be involved in its protection

The Technical Advisory Group (TAG) on biodiversity, hereafter called Biodiversity TAG, is composed of 25 international experts in ecology, biodiversity indicators, agronomy, life cycle assessment, livestock production systems, and environmental science. Their backgrounds, complementary between systems and regions, allowed them to understand and address different perspectives. The aim of the methodology developed in these guidelines is to introduce a harmonized international approach for assessing the impacts of livestock on biodiversity. The livestock sector is a major user of natural resources (land in particular) and an important contributor to pollution (e.g. causing nutrient losses, increasing greenhouse gas emissions), which makes it one of the sectors with the highest impact on biodiversity. At the same time, livestock production is one of the few sectors with not only negative but also positive impacts on biodiversity; therefore, the sector can pull two levers to improve its biodiversity performance – mitigate harm and maximize benefits. Many environmental assessments of the livestock sector have not addressed biodiversity because of its intrinsic complexity. These guidelines strive to include biodiversity in environmental assessments, in order to increase the understanding of the impacts of livestock on biodiversity and to reveal possible synergies or trade-offs with other environmental criteria or Sustainable Development Goals (SDGs). Several indicators in these guidelines are also of relevance for the UN Decade on Ecosystem Restoration.

This "in brief" version, intended for use by decision-makers and the wider public, presents a summary of the key findings of the main report (see above). Part 1 outlines the state of agricultural biodiversity in the livestock sector. Part 2 considers the livestock production systems of which animal genetic resources form a part. Part 3 - largely based on the 148 Country reports - is an assessment of institutional and human capacity in the field of animal genetic resources management. Part 4 presents the state of the art in terms of the methods available for the management of animal genetic resources. As well as providing a technical reference document, the country-based preparation of The State of the World" has led to a process of policy development and a Global Plan of Action for Animal Genetic Resources, which once adopted, will provide an agenda for action by the international community.

Livestock grazing is the most widespread commercial use of federal public lands. The image of a herd grazing on Bureau of Land Management or U.S. Forest Service lands is so traditional that many view this use as central to the history and culture of the West. Yet the grazing program costs far more to administer than it generates in revenues, and grazing affects all other uses of public lands, causing potentially irreversible damage to native wildlife and vegetation. The Western Range Revisited proposes a landscape-level strategy for conserving native biological diversity on federal rangelands, a strategy based chiefly on removing livestock from large tracts of arid BLM lands in ten western states: Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming. Drawing from range ecology, conservation biology, law, and economics, Debra L. Donahue examines the history of federal grazing policy and the current debate on federal multiple-use, sustained-yield policies and changing priorities for our public lands. Donahue, a lawyer and wildlife biologist, uses existing laws and regulations, historical documents, economic statistics, and current scientific thinking to make a strong case for a land-management strategy that has been, until now, "unthinkable." A groundbreaking interdisciplinary work, The Western Range Revisited demonstrates that conserving biodiversity by eliminating or reducing livestock grazing makes economic sense, is ecologically expedient, and can be achieved under current law.
