Enabling diverse actors to address interlinked sustainability issues is important and challenging. This paper focuses on how to design a dialogue-based knowledge co-production process to nurture collective action. Using the conceptualization of systems, target, and operational knowledge as the guiding framework, we designed and combined different complementary activities to invite actors to look at a wicked problem through multiple lenses and reflect on their own positions, perspectives, knowledge, and values. With a carefully documented workshop series held with local actors on Öland, Sweden, as our empirical case study, we demonstrate how we moved from exploring the multifunctionality of landscapes and understanding actors’ different values, preferences, and priorities, to developing four strategies for effectively accelerating and expanding efforts to adapt to climate change. Our study reveals how the process of mobilizing, articulating, and connecting individually held systems, target, and operational knowledge nurtures collective action. It also leverages dialogue-based processes as cornerstones in addressing sustainability challenges in an inclusive and equitable way.
