Diverse values, interests, and needs are associated with nature-based solutions. It is therefore important that they are taken into account in decision-making. As engaging communities contribute to realising all the sustainability benefits of nature-based solutions the "Citizen Engagement Handbook" on community engagement outlines how to engage diverse communities and actors in decision-making.

The handbook also includes guidance on how marginalized groups can be reached and included, and describes what works in terms of approaches and methods to citizen engagement for nature-based solutions. The handbook provides a valuable resource for organisations that are working with nature-based solutions at the grassroots level.
