Revitalization of an environment

Action to rehabilitate a more or less artificialized environment to its original and natural status. By trying to rehabilitate all the physical characteristics of the environment (e.g. meanders recovered in an improved river), revitalization aims to recover all the initial potentials of the environment in terms of biological diversity, self-cleaning capacity, etc. Most ambitious than restoration, revitalization aims to globally recreate the ecological functioning and biodiversity of the bed, river banks, flows, etc. of a river degraded by hydraulic work or other human activities.
