Integrating ecological knowledge with legal instruments for nature conservation in river management

Contains fulltext : 29837.pdf (publisher's version ) (Open Access)Legal instruments for nature conservation make knowledge on actual and potential presence of protected and endangered species in river floodplain ecosystems an important issue in river management. Within river management, many physical reconstruction and management plans are currently being carried out and planned. The expected effects on biodiversity are massive and can be positive as well as negative. Huge amounts of ecological knowledge will be required to do the legally obligatory assessments. Ecology and legislation are two crucial frameworks for nature conservation in river management. In this thesis, a model that can integrate ecological knowledge with legal instruments for nature conservation in river management is developed, evaluated and applied. The relation between ecological knowledge and legal instruments is studied by analysing goals, approaches towards nature and species selection and terminology of the two frameworks. Based on the results of the study it is concluded that BIO-SAFE is an operational and scientifically underpinned model for integration of ecological knowledge and information with legal instruments for nature conservation in river management, that provides useful information in evaluation studies, is valid for impact assessments and insensitive to value judgements. Application of the model showed the effects of river management measures on actual and potential presence of protected and endangered river species. The measures taken can be optimised by increasing the spatial scale, and using detailed knowledge on local potentials. When landscape heterogeneity is maximized and low and intermediate dynamic circumstances are conserved and developed, nature conservation can be combined with flood risk reduction and ecological rehabilitation. The ecological and the legal framework for nature conservation have different goals, criteria for making valid claims and approaches towards nature and species selection. However, there are various opportunities for bridging the gaps in practice, e.g. in jurisprudence, management plans, codes of conduct and effect studies.RU, Environmental Science, 10 november 2006Promotor : Nienhuis, P.H.

Evolution of river management: up to integrated and beyond?

Integrated river management is heralded as the new style of river management, but it has been preceded by a number of previous styles, and is unlikely to be the last. This article presents the first analysis of the evolution of river management using Spiral Dynamics (SD). SD provides a growth hierarchy of value systems (vMemes), reflecting increasing complexity and inclusiveness ranging from instinctive to holistic. Based on an interpretation of literature and policy documents, we conclude that (1) SD provides a broad interpretative framework that can be applied in all river basins, (2) river management in the Netherlands shows the subsequent dominance of the blue, orange, and green vMeme, yellow is at the take-off phase, (3) further transition to yellow integrated river management requires identification of barriers to change. We give an overview and policy implications. Further research should be oriented towards quantification of vMemes in stakeholders and landscaping measures
