Governance Conditions for a Successful Restoration of Riverine Ecosystems, Lessons from the Rhine River Basin.

Over the years, human impacts have resulted in great losses in riverine biodiversity. Ecosystem restoration could contribute to reversing this trend. Ecosystem restoration, however, involves many actors and perspectives and is, therefore, a complex governance challenge. So far, this governance challenge has been understudied, and it is not clear which governance conditions may contribute to a successful restoration of riverine ecosystems. This paper addresses this knowledge gap by developing an assessment framework that is applied in a critical case study. We first reviewed scientific papers and compiled governance conditions found in an assessment framework. The framework is tested and refined by conducting a case study on the ecosystem restoration process coordinated by the International Commission for the Protection of the Rhine. This process aims to bring back the Atlantic salmon and other species in the basin. Our analysis revealed that despite efforts to reintroduce Atlantic salmon, a self-sustaining population is not present in the basin. Moreover, the governance structure in the basin only meets 13 out of 23 governance conditions. Challenges identified include slow decision-making, ambiguity in responsibilities, and limited financial incentives. Based on our case study, we have refined the framework to tailor it more for future research and policy development. [ABSTRACT FROM AUTHOR]
