Evaluating Nature-Based Solutions (NBS): Best practices, frameworks and guidelines

A desk study was performed on Nature Based Solutions (NBS), focusing on commonalities, differences, gaps and opportunities for implementation and evaluation of NBS. A qualitative evaluation framework was developed to assure that essential elements are included in projects with Nature-Based Solutions (NBS). A key aspect of the proposed framework was to make a distinction between efficiency and effectiveness in both the design and implementation phases of the project.

Next, the framework was applied to three example NBS cases:

  • Case 1: Belgium – River Kleine Nete
  • Case 2: Netherlands – side channels (Room for the River)
  • Case 3: Scotland – Eddleston water

The example cases highlighted opportunities for improved implementation practices of NBS. This study was commissioned by the Ministry of Infrastructure and Water Management.
