tailieunhanh - Science and Policy in Natural Resource Management

This is probably the first study that has used resilience, the adaptive cycle and panarchy as a major part of the conceptual foundation for the work. Resilience (as used here) has been explored in the literature for about 30 years, the adaptive cycle originated about 18 years ago and both have been integrated within the panarchy concept for only a few years. The authors combine these concepts with soft systems science conceptual modelling tools to review and assess the character of agricultural development from an integrated perspec- tive of economic, social and ecological changes over about 100 years. They then apply these methods in a strategic analysis of. | Science and Policy in Natural Resource Management Mdcnunding Syưrnt Carnality Helen Allison and Richard Hobbs This page intentionally left blank Science and Policy in Natural Resource Management Understanding System Complexity Despite many well-intentioned policies and changes to our management practices our 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 Australian agricultural region can be used to clearly demonstrate the principles for other commodity systems. Aimed at academics and researchers through to policy analysts this book will inspire innovation and action in sustainable natural resource management. HELEN E.
