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 70s, the lower course of the Arga River near the confluence with the Aragon River flowed with a meandering channel, occupying a wide flood plain characterized by intense fluvial dynamics. In this situation, it was considered necessary to carry out works to contain river floods, by rectifying and channel the section stretching 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.
Pursuant to the Water Framework Directive and in accordance with the environmental objectives of the Hydrological Plan of the Tagus River Hydrographic Basin, in coordination with Patrimonio Nacional (as the entity that manages the Monte de El Pardo area), the improvement of the ecological condition of the river has been proposed as well as the recovery of this space of great environmental value, from the Pardo Reservoir to the confluence with the La Trofa stream (a distance of approximately 6 km).
