La quatrième de couverture indique : "The rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. Over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. Livestock in a Changing Landscape offers a comprehensive examination of these important and far-reaching trends and presents new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production. The two volumes represent an essential resource for policy makers, industry managers, and academics. Volume 1, Drivers, Consequences, and responses, examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses."
