Ecosystem management

Ecosystem management is an approach to environmental governance that treats ecosystems as complex adaptive systems rather than as machines to be optimized. Unlike traditional resource management, which typically targets a single species or commodity (maximum sustained yield, timber production, water extraction), ecosystem management attempts to maintain the system's functional diversity, resilience, and adaptive capacity across multiple scales and stakeholder interests.\n\nThe approach emerged from the critique of maximum sustained yield fisheries management in the 1990s, when the collapse of the Northwest Atlantic cod fishery demonstrated that optimizing for a single target state could destroy the very properties that sustained the system. The lesson was generalized: any management strategy that maximizes short-term efficiency at the expense of long-term resilience is not management but liquidation. Ecosystem management accepts the trade-off: lower average yield in exchange for lower variance and higher survival probability under novel conditions.\n\nThe implementation challenge is governance. Ecosystems do not respect administrative boundaries, and the stakeholders who depend on them — fishers, farmers, urban water users, conservationists — often have conflicting objectives. Adaptive governance and polycentric governance are institutional frameworks designed to match the cross-scale, multi-actor dynamics of ecosystems. They are not panaceas. They are experiments in managing systems that are too complex to control and too important to ignore.\n\n\n\n
