The overall objective of the Building with Nature project is to make coasts, estuaries and catchments of the North South region (UK, Norway, Sweden, Denmark, Germany, Belgium and The Netherlands) more adaptable and resilient to the effects of climate change using nature based solutions. The Building with Nature project will exchange experiences (bad and best practices) of Building with Nature projects in this region. They involve 7 coastal target sites in NL, D, DK, SE (sand nourishment at North Sea Coasts and Wadden Sea barrier islands) and at 6 catchment scale sites in B, NL, SE, SCO (e.g. river restoration, room for the river and wetlands) referred to as 'laboratories'. The Building with Nature project creates joint transnational monitoring programmes, uses state-of-the-art analysis methods, develops improved designs and business cases. The laboratories generate the evidence-base to incorporate building with nature concepts in national policy and investment programmes of each of the NSR countries (worth >€200M/y).
