The Deba river basin (area: 534km2) in the Basque Country (Spain) contains urban, peri-urban as well as agricultural areas and is home to around 135000 residents.
The hydro-geomorphology of the Deba River basin in the Basque country will be restored, mainly through dam demolition, restoring river morphology, connectivity and faunal permeability. Stakeholder interaction is being promoted, connecting local communities, institutions and governments. A main objective is to promote environmental education and the conceptualisation of nature-based solutions oriented restoration policies.
This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation
