A tension between a scientific «expert» knowledge and a «traditional» localknowledge has always crossed Disaster Risk Reduction policies and practices.Big detention basins or large engineering works are usually preferred by delegatedagencies for flood risk mitigation measures based on scientific hydraulicmodels. Due to economic or geo-morphological reasons these solutions can’tbe always implemented, and so challenging «traditional» cost-benefit analysis.This was the case of a six-year project called Rural Sustainable Drainage System(RSUDS), led since 2014 by the local government of Stroud, a village inSouth West England. Following the 2007 major floods occurred in England,four action groups were formed in the study site to demand for further floodrisk mitigation measures. Due to the inefficiency of the engineering solutionsproposed, which consisted of two large ponds working as detention basins,the bottom-up process resulted in the implementation of nature-based solutionsconsisting also of dozens of different small ponds with different functions toprevent from flooding. The different actors were bearers of different kind ofknowledges, which interacted at local level, driven by relationships betweenactors and between actors and water catchments. Situated relationships andpractices activated and produced local knowledges, due to the role of waterflowing in shaping risk and risk framing. In terms of lesson learned, this casestudy showed how considering local knowledge in flood risk framing andmanagement can refer to the multiple functions of nature-based solutions andbe a threshold for effectiveness.
