Adaptive management is a key aspect of ESEM.  Adaptive management is a way of approaching environmental management.  It assumes that there is a great deal of uncertainty in environmental systems and holds that there is never a final solution to an earth systems problem.  Therefore, once action has been taken, the Earth Systems Engineer will need to be in constant dialogue with the system, watching for changes and how the system evolves. This way of monitoring and managing ecosystems accepts nature's inherent uncertainty and embraces it by never concluding to one certain cure to a problem.
