Redefinition and Elaboration of River Ecosystem Health: Perspective for River Management

摘要: This paper critically reviews developments in the conceptualization and elaboration of River Ecosystem Health (REH) concept. Analysis literature shows there is still no consistent meaning central concept Health, resulting models (i.e. elaborations) that have unclear insufficient conceptual grounds. Furthermore, a diverse terminology associated with describing REH, confusion other concepts. However, if to merit longevity field river research management, unambiguous definition operational domain are required. Therefore redefinition proposed, based on identified characteristics health derived from considering semantic definitions. Based this definition, REH has broader context system considers societal functioning next ecological functioning. Assessment needs integration measures multiple, complementary attributes analysis synthesized way. An assessment framework proposed assesses top-down as well bottom up by combining indicators stress responses condition) identifying causative stressor). The scope covered using activity, metabolism (vigour), resilience, structure interactions between components (organization). variety effects may endure biotic, chemical physical stressors. Besides having unique meaning, metaphor added value management being able mobilize scientists, practitioners publics seeing relationships at level values. It places humans centre ecosystem, while seeking ensure durability ecosystem which they an integral part. Optimization indicator set, development aggregation classification methodologies, implementation within differing international frames considered main aims for future research.
