Pacific Small Island Developing States are often referred to as the “frontline” of climate change, facing an array of worsening climate-related shocks and stressors. However, despite their underlying exposure to climate change impacts, the role of Pacific Island cities as both an avenue for adaptation and sites of climate vulnerability is often overlooked. This paper reflects on two ongoing participatory action research projects conducted by UN-Habitat and research partners from Australian universities in Honiara, Solomon Islands, and Port Vila, Vanuatu. Findings from community consultations across 16 communities in these settings demonstrate the critical role of endogenous modes of resilience, as well as the strong correlation between these spaces and sub-city climate vulnerability. Cross-scale integration with climate resilience planning processes is then used to examine points of conflict between stakeholder interpretations of core functions within socioecological systems, demonstrating the importance of considering values and conflict within urban climate adaptation.
