This book was first published in 2006. Despite many well-intentioned policies and changes to management practices, the world's natural resources continue to decline. The roles and interplay between science and policy in the regional broadacre agriculture landscape are examined here, offering readers a thorough understanding of the complex interactions that occur across spatial scales to produce the regional-scale impacts. The fundamental causes of resource degradation, social decline and environmental pollution are addressed, examining the cross-scale drivers from the individual farm level to the global level of commodity systems. Broadacre agriculture is a common land use throughout all continents of the world and is driven by the same type of dynamics, and this case study of the Western Australia agricultural region can be used to clearly demonstrate the principles for other agricultural systems. Aimed at academics, ranging from researchers through to policy analysts, this book will inspire innovation and action in sustainable natural resource management.
