"... in this article, we present the results of a collective self-assessment exercise for a panel of eight case studies (covering four continents) [Amazon rainforest, Brazil; Colombia; India; Bangaldesh; Egypt; Lake Manyara Basin, Tanzania; Baltic Sea, Germany; Isles of Scilly, UK] ] of communications between project teams and local communities within the context of climate change or biodiversity loss. Our analysis develops eight indicators of good stakeholder communication, which we construct from the literature, in addition to Verran (2002) 's concept of postcolonial moments as a communicative utopia. Our study contributes to the (analytical) understanding of such communications, while also providing tangible insights for field work and policy recommendations. We demonstrate that applying our indicators can foster a more successful communication, although we find an apparent divergence between timing, complexity, and (introspective) effort of the project teams. While three case studies qualify for postcolonial moments, our findings show that especially the scrutiny of power relations and genuine knowledge co-production are still rare. We verify the potency of various instruments for deconstructing science; however, we also show that their sophistication cannot substitute other crucial factors. Instead, simple deconstruction efforts may suffice, while trust-building, proper time management, and an advanced awareness of the scientists are crucial. Lastly, we consider that reforming rigid and inadequate funding policies will help overcome significant barriers and improve the work in and with local communities." (Abstract)
