Hard infrastructuring of rivers vs. Nature-based solutions: dynamic status-quo?

Résumé

The hard infrastructuring of rivers has often been considered essential to accompany human development and remains today a way of thinking about the link to rivers in order to minimise the impacts of global changes. This choice is deeply embedded in the engineering society, but different trends prompt stakeholders to adapt their visions and to become softer. This last decades, the principles of ecological river management have been adopted with a removal of some infrastructures and processes of ecological restoration. New ways of thinking the relationships to the rivers have been emerging through hybrid solutions combining of grey and green infrastructures to integrate considerations of biodiversity conservation, climate change adaptation. Actually, environmental constraints and narratives urge the professional culture of the hegemonic civil engineering to adapt their practices and to integrate other ways to work with the rivers. That is why it appears interesting to question, that the promises of infrastructure can be renewed with climate change concerns and to study the ongoing process of "dynamic status quo" between a dominant infrastructuring movement and those promoting nature-based solutions. As the agentivity of non-humans is constantly reminded through extreme events and dysfunctions of the human artefacts, “the classic hydraulic tradition” is obliged to evolve and, in the same time, criticised and challenged by the emerging “Nature based solutions” epistemic community, more and more supported by local and national authorities (funding, regulatory norms, etc.). We will illustrate our reflection though the discussion of two case studies dealing with two rivers (Seine and Rhine).
