The islands of Macaronesia are not spared from the effects of climate change, being very vulnerable to their consequences given their particular geographical situation, insularity, remoteness from the continent, fragmentation, external dependency, scarcity of natural resources, demographic density, dependence on the tourism sector and great biodiversity.

Until the 1970s, the lower section of the Arga River, near its confluence with the Aragón, meandered through a wide floodplain, with intense fluvial dynamics. At the time, it was deemed necessary to carry out works to contain the river's floods, leading to its rectification and channelling in the section from the town of Falces to the mouth of the Aragón River.

The European LIFE CERSUDS project (Ceramic Sustainable Urban Drainage System) is developing sustainable urban drainage systems (SUDS) that use ceramic materials of low commercial value as a filter system for construction or paving. Its main objective is to improve the capacity of cities to adapt to climate change and to promote the use of green infrastructures in their urban planning for the rehabilitation of such urban areas. To achieve this, LIFE CERSUDS has developed and implemented a sustainable urban ceramic drainage system with low environmental impact.

The Manzanares River, as it passes through the historic Royal Site of El Pardo, has undergone various hydromorphological alterations over the years, which profoundly transformed both the riverbed and its banks. These transformations resulted in the significant loss of river space, habitat diversity, both longitudinal and transverse connectivity of the river, and public accessibility to its banks.
