Pacific Islands, many relatively remote and small, have been occupied by people for more than 3000 years during which time they experienced climate‐driven environmental changes (both slow and rapid onset) that challenged human survival and led to the evolution of place‐based coping strategies expressed through traditional knowledge (TK). In today's globalized Pacific Islands region, into which western worldviews and global adaptation strategies have made significant inroads, most plans for coping with climate‐changed futures are founded in science‐based understandings of the world that undervalue and sideline TK. Many such plans have proved difficult to implement as a consequence. This paper reviews the nature of extant Pacific TK for coping with climate change, something that includes TK for anticipating climate change (including climate variability and climate extremes) as well as ancillary TK associated with food and water security, traditional ecological knowledge, environmental conservation, and settlement and house construction that represent coping strategies. Much of this TK can be demonstrated as being effective with precedents in other (traditional) contexts and a compelling plausible scientific basis. This study demonstrates that Pacific Islands TK for coping with climate change has value and, especially because of its place‐based nature, should be central to future climate‐change adaptation strategies to enhance their uptake, effectiveness and sustainability. To this end, this paper proposes specific ways forward to optimize the utility of TK and ensure it has a realistic role in sustaining Pacific Island communities into the future.

Sixteen hillforts constructed and occupied perhaps several centuries before contact in the early nineteenth century are described from Bua district in northern Fiji. These hillforts represent inland settlements in fortifiable locations on high volcanic islands, plausibly established in response to the outbreak of sustained conflict. The chronology and functions of these hillforts were investigated through mapping, excavation, and collection of oral traditions. Four groups of hillforts are recognized. The Seseleka and Yadua (Island) groups represent single polities, comprising a mountaintop site surrounded with fortified narrow steep-sided basalt ridges with tributary sites at lower levels functioning as lookouts and/or food-processing sites. The Northwest Bua group comprises mountaintop sites occupied only when aggressors threatened, and are otherwise characterized by occupation around their bases. The Inland Bua group ranges along one of the highest ridges in the area and were all reportedly in conflict with each other. The Buan hillforts represent those found elsewhere in Fiji and on other high Pacific Islands. Insights from the study of these hillforts illuminate this period of Fiji history and help interrogate broader questions about drivers and proximate causes of the conflict that may have seen hillforts established near simultaneously on high Pacific Islands during the last millennium.

A study of various defining aspects of 11 rural communities along the cross-island road on Viti Levu (Fiji) shows diversity attributable largely to their peripherality, proxied by distance along this 200-km long road. Strong relationships are found between peripherality and both community size and the dependency ratio (percent of young/old dependents), as well as traditional medicine usage (and percent traditional healers), and autonomous community coping after disasters. Two measures are calculated to capture community autonomy, both of which proxy peripherality. Results show the usefulness of peripherality as a way of measuring community diversity in developing-country contexts. Peripherality also correlates with community autonomy, more-peripheral communities having greater autonomous coping abilities/capacity than near-core (less-peripheral) communities. Results also show the unhelpfulness of the default '"one-size-fits-all'" approach to communities implicit in many external assistance programs. Yet while traditional coping in such communities may not be able to fully overcome future climate-change challenges, the conservation of the traditional knowledge underpinning this should be encouraged, mainly because of the likelihood that external funding for future adaptation in such communities will be inadequate. The best hope for effective and sustainable adaptation to future climate change, focused on sustaining livelihoods, lies in strengthening autonomous community coping. [ABSTRACT FROM AUTHOR]

Over the past thirty years, externally-driven interventions for climate-change adaptation in rural Pacific Island contexts have largely failed to be effective or sustained. One reason is that traditional (culturally-grounded) autonomous community coping capacity has been overlooked, many external agencies viewing all such communities as both homogenous and helpless. A community's autonomous coping capacity can be proxied by peripherality, a measure of the degree to which a particular community in archipelagic (island) countries engages with core agendas. In order to gauge the depth, breadth and efficacy of autonomous coping capacity, three indices of community peripherality were developed from research within thirteen communities in (peripheral-biased) Bua Province in Fiji. Index 1 concerns geography (travel time/cost to town), Index 2 concerns population and employment (community size, age distribution, employment), and Index 3 concerns tradition and global awareness (mobile phones per capita, traditional/western healthcare preferences, inherent coping capacity, diet, water and energy security). Mapping of Indices 1–3 allows the nature of community peripherality in Bua to be captured using a readily-reproducible tool for rapid assessment in similar contexts. It is demonstrated that an understanding of peripherality (as a proxy for autonomous community coping capacity) can inform the design of future interventions for climate-change adaptation.
