The purposeof the Stakeholder Engagement Strategy (SES) is to give both theoretical and practical guidance tofacilitate sustainable engagement of stakeholders in the INTERLACE project. In the first place, thisguidance is meant for all INTERLACE partners who are involved with stakeholder engagement.Secondly, this guidance can be used by anyone who is involved with stakeholder engagement in urbanNature-based Solutions projects.This guidance integrates an agile workflow and contains a logical step-to-step approach to create atailored plan for engagement activities (see the 10 steps below, or download the visual summary here).To support this, an INTERLACE specific categorization of stakeholders is applied. Additionally, goodpractices are discussed and a troubleshooting section is included to support with possible challengesthat can be encountered during stakeholder engagement.
