Ecosystem Evaluation founder, Agnes Zolyomi published a book chapter, “How to Make Policy-Makers Care about “Wicked Problems” such as Biodiversity Loss?—The Case of a Policy Campaign”. Here, she provides an overview of current biodiversity communication methods (including ecosystem services, flagship species, emotions). Based on experiences drawn from a conservation and advocacy NGO’s work, the chapter also divulges various socio-economic theories about creative methods, communication, and influencing decision-makers through a campaign fighting for the preservation of key nature legislation. It is demonstrated how different EU policy-makers, including representatives of the European Commission and Members of the European Parliament, the general public, and other stakeholders, were addressed with various messages and tools (e.g., short films, social media campaigns, fact sheets, involvement of champions). The chapter is available to download on Springer’s website here.
