The Netherlands IHP-HWRP Committee aims to add to the WWDR2018 by collecting Nature Based Solutions (NBS) from over the globe that are able to show the theory of the report in practice. The goal is to strengthen the message in the report, by demonstrating how NBS have been put in practice. The case-study collection that is then created, will also try to take the guiding principles into account in presenting the cases. The case studies will therefore demonstrate:

  1. what the NBS is and for which problem it has been designed;
  2. why the case study is a NBS and why it was chosen above a so-called grey solution;
  3. what the hydrological and socio-economic evidence is to demonstrate that the solution was successful; and
  4. how it came to be a sustainable solution for the system as a whole and how policy was involved to enable the implementation into this same system.

We envision the case-studies to be publicly visible online via an e-version. In this way, case studies can be demonstrated a dynamic way, with small scale and low tech vlogs and videos, making an interactive environment that can be used by all. IHE Delft will then design a pamphlet that will shortly mention your case-study and refer back to the e-version for more information on each case study.

We will focus on NBS in urban deltas and the catchments that provide them of food, water and energy. The first version of the case-study collection will be launched during the 8th World Water Forum in Brasil on the Holland Pavilion. By contributing to this collection, you will be able to demonstrate your project to many decision-makers, students, experts, and civil servants all over the world, who will be able to use the collection as practical examples next to the theory of the WWDR2018.
