Climate change and urbanisation in combination put great pressure on terrestrial and ocean ecosystems, vital for subsistence and wellbeing in both rural and urban areas of Pacific islands. Adaptation is urgently required. Nature-based solutions (NbS) offer great potential, with the region increasingly implementing NbS and linked approaches like ecosystem-based adaptation in response. This paper utilises three Pacific island nation case-studies, Kiribati, Samoa and Vanuatu, to review current NbS approaches to adapt and mitigate the converging resilience challenges of climate change and urbanisation. We look at associated government policies, current NbS experience, and offer insights into opportunities for future work with focus on urban areas. These three Pacific island case-studies showcase their rich cultural and biological diversity and, importantly, the role of traditional ecological knowledge in shaping localised, place-based, NbS for climate change adaptation and enhanced wellbeing. But gaps in knowledge, policy, and practice remain. There is great potential for a nature-based urban design agenda positioned within an urban ecosystems framework linked closely to Indigenous understandings of wellbeing.

Pacific Island Countries (PICs) are often cited as being the most vulnerable to the future impacts of a changing climate. Furthermore, being located in the ‘Pacific Rim of Fire’, PICs have long been exposed to the impacts of a range of natural and climate-related extreme events—such as earthquakes and cyclones—and are considered to be amongst the most vulnerable countries to natural disasters. The physical vulnerability of Pacific towns and cities is further exaggerated by development deficits, geographical isolation, weak governance, and complex issues of land tenure. This paper, based on substantive project experience in the Pacific region by each of the authors, reviews the resilience challenges facing Melanesian cities in the context of rapid urbanization and global environmental change. It then sets this in the context of the global ‘New Urban Agenda’ which was launched at Habitat III in Quito at the end of 2016, setting out the critical implementation challenges and opportunities for enhancing urban resilience in the Pacific.

Many coastal peri-urban and urban populations in Oceania are heavily reliant on terrestrial and marine ecosystem services for subsistence and wellbeing. However, climate change and urbanisation have put significant pressure on ecosystems and compelled nations and territories in Oceania to urgently adapt. This article, with a focus on Pacific Island Oceania but some insight from Aotearoa New Zealand, reviews key literature focused on ecosystem health and human health and wellbeing in Oceania and the important potential contribution of nature-based solutions to limiting the negative impacts of climate change and urbanisation. The inextricable link between human wellbeing and provision of ecosystem services is well established. However, given the uniqueness of Oceania, rich in cultural and biological diversity and traditional ecological knowledge, these links require further examination leading potentially to a new conceptualisation of wellbeing frameworks in relation to human/nature relationships. Rapidly urbanising Oceania has a growing body of rural, peri-urban and urban nature-based solutions experience to draw from. However, important gaps in knowledge and practice remain. Pertinently, there is a need, potential—and therefore opportunity—to define an urban design agenda positioned within an urban ecosystem services framework, focused on human wellbeing and informed by traditional ecological knowledge, determined by and relevant for those living in the islands of Oceania as a means to work towards effective urban climate change adaptation.

East Rennell was placed on the List of World Heritage in Danger in 2013. Threats to the site's Outstanding Universal Value include logging, mining, invasive species, and climate change. The site is unlikely to be removed unless actions identified in the 2015 Desired state of conservation for removal of the property from the List of World Heritage in Danger (DSOCR) are implemented. While the Solomon Islands Government has taken some steps towards implementing the DSOCR, overall progress has been minimal, partly due to competing priorities and lack of resources. Consequently, it is unlikely that the DSOCR will be achieved by the target date of 2021. East Rennellese have received little financial benefit from the site's listing and their support for World Heritage may be wavering. To be effective, World Heritage conservation measures must be aligned with local peoples' aspirations and priorities, which include improving livelihoods and preserving culture.
