The parties involved in the Delta Programme have been working on the implementation of the Delta Decision on Spatial Adaptation since October 2014. The Delta Programme supports their efforts through the development and exchange of knowledge, the Incentive Programme, the Knowledge Portal, and a learning evaluation process based on monitoring (2015, 2016) and an interim evaluation (2017). Municipalities mapping out vulnerabilities qualify for support in the performance of stress tests. The Delta Programme has supported the launch of fifteen impact projects, ten of which have already been completed. The results have been disseminated in various ways, including through the Knowledge Portal.
