Floating islands, a nature-based solution for the ecological integrity promotion in rivers? - The case of Fervença river (NE Portugal). In Online Symposium on Circular Economy and Sustainability. Alexandroupolishttp://hdl.handle.net/10198/26924Despite the existence of the Water Framework Directive (Directive 2000/60 / EC of 23 October, modified in 2019) and a set of “satellite legislation” advocating that water quality depends not only on the good physical-chemical state, but also on the good ecological status of freshwater ecosystems, these continue to be subjected of accelerated ecological degradation. Indeed, freshwater ecosystems are considered to be the most threatened ecosystems on the planet (Dudgeon et al., 2006). Urban rivers and streams are crucial to cities, because they provide environmental services that are essential to maintaining urban environmental quality (Hua & Chen, 2019). Nevertheless, many of the so called “urban river rehabilitation actions”, carried out either the past, either recently, promoted the regularization of the riverbeds and the riverbanks leading to riparian wood degradation and consequently to the entire riverine structure collapse.engUrban riversUrban ecological integrityNature-based solutionsFloating islandsconference object
