The next in the series of webinars on Building with Nature

The International Association of Dredging Companies (IADC) and the International Institute for Sustainable Development (IISD) are organising a webinar to discuss the findings of the SAVi Assessment of the Hondsbossche and Pettemer (H&P) sea dunes.

The webinar on the Hondsbossche and Pettemer (H&P) sea dunes is taking place on 24 March 2022 at 4pm CET.

The assessment quantifies the ecosystem services and economic impacts of the new dune landscape under several flood scenarios and compares this nature-based infrastructure solution to a conventional dike reinforcement.

The study finds 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.

Constructing new marine infrastructure or maintaining ports and waterways has both a positive and sometime a negative effect on the environment.

That’s why sustainability throughout the dredging industry is key. And finding nature-based solutions is crucial. To become truly sustainable all impacts should be considered in project evaluations.

The influence on biodiversity or recreation opportunities, for instance, are hardly taken into account in project evaluations. IADC believes in promoting inclusion of all externalities.

The result of the SAVi assessment of the Hondsbossche and Pettemer sea dunes shows the benefits of nature-based solutions and the additional value that can be created.
