In this research, the creation, use and spread of knowledge acquired in Building with Nature pilot projects is researched, with the goal of providing recommendations to improve this use and spread in future Building with Nature pilot projects. To achieve this, a case study with the Sand Engine as the subject is performed. In addition to this, a literature review and interviews were undertaken, and two System Dynamics models were created which were applied to the Sand Engine case. As a results, seven recommendations for future pilots were found: First, ensuring the internal success of the pilot is crucial. 2. Including knowledge creation and spread as design factors in the pilot project design, 3. Designing the pilot project to be multi-functional, 4. Ensuring the pilot project fits the long-term policy plans and strategy of important stakeholders, 5. Involving champions of knowledge, who are able to turn over the project at the right time, 6. Implementing knowledge programs within the pilot project and 7. Ensuring the free sharing of knowledge between stakeholders and interested parties. Recommendations for further research and policy include performing complementary case studies on other Building with Nature pilot projects, expanding the number and variety of interviewees, and implementing a new format of data collection, management and storage in Building with Nature pilot projects.
