The Hondsbossche Dunes are a nature-based coastal protection solution in the Netherlands. The artificial dune landscape stretches along 7 kilometres of the Dutch North Sea coast.

In this report we present the results of the Sustainable Asset Valuation (SAVi) assessment of the Hondsbossche Dunes project. The assessment quantifies the ecosystem services and economic impacts of the new dune landscape under several flood scenarios and compares this NBI solution to a conventional dike reinforcement.

We find that under all scenarios, the investment in the artificial sand dunes offers greater net benefits than the grey alternative of building a sheet pile wall.
