Concept
Ecosystem management
Résumé
Ecosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ecosystem's function and services while meeting socioeconomic, political, and cultural needs. Although indigenous communities have employed sustainable ecosystem management approaches implicitly for millennia, ecosystem management emerged explicitly as a formal concept in the 1990s from a growing appreciation of the complexity of ecosystems and of humans' reliance and influence on natural systems (e.g., disturbance and ecological resilience).
Building upon traditional natural resource management, ecosystem management integrates ecological, socioeconomic, and institutional knowledge and priorities through diverse stakeholder participation. In contrast to command and control approaches to natural resource management, which often lead to declines in ecological resilience, ecosystem management is a holistic, adaptive method for evaluating and achieving resilience and sustainability. As such, implementation is context-dependent and may take a number of forms including adaptive management, strategic management, and landscape-scale conservation.
The term “ecosystem management” was formalized in 1992 by F. Dale Robertson, former Chief of the U.S. Forest Service. Robertson stated, “By ecosystem management, we mean an ecological approach... [that] must blend the needs of people and environmental values in such a way that the National Forests and Grasslands represent diverse, healthy, productive and sustainable ecosystems.”
A variety of additional definitions of ecosystem management exist. For example, Robert T. Lackey emphasizes that ecosystem management is informed by ecological and social factors, is motivated by societal benefits, and is implemented over a specific timeframe and area. F. Stuart Chapin and co-authors emphasize that ecosystem management is guided by ecological science to ensure the long-term sustainability of ecosystem services, while Norman Christensen and coauthors emphasize that it is motivated by defined goals, employs adaptive practices, and accounts for the complexities of ecological systems.
