Lessons from experience with ecosystem-based management
MetadataShow full item record
Pushed by recognition of the problems of fragmented management and growing interest in synthetic management goals such as sustainable development, biodiversity and ecosystem integrity, ecosystem-based management is of growing intellectual and practical significance in North America and elsewhere. Ecosystem-based management has several roots: the ecosystem approaches developed in several disciplines in the 1960s and 1970s, and earlier; more general systems approaches; and regional, bioregional, watershed and integrated resource management approaches. Although building on these, ecosystem-based management is a distinct activity that also draws on and complements ecosystem science, conservation biology, and environmental planning. Ecosystem-based management seeks to transcend arbitrary political and administrative boundaries, to achieve more effective, integrated management of resources and ecosystems at regional and landscape scales. Several key components of ecosystem-based management can be identified: defining the management unit, developing understanding, and creating planning and management frameworks. This paper draws on case studies of progress toward ecosystem-based management in Canada, the USA, and Australia to highlight lessons for implementing ecosystem-based management, and the need for new goals for it, in order to foster further, future development.
