Where relocation is successful, it is most commonly driven and funded by governments and non-government organisations, often within a specially designed policy framework. The Government of Fiji, for example, has introduced a relocation framework that specifically develops guidance on relocation processes, with several villages already having relocated. Evaluations to date recommend thorough cost -- benefit analyses of relocation be undertaken before this strategy is pursued. Relocation is often viewed as a 'last resort' adaptation option because of high cost and because some sociocultural aspects of life cannot be maintained in locations separated from customary land. The Bahamas relocated a community on Family Island from the shoreline to an inland location and the community of Boca de Cachon in the Dominican Republic was relocated to higher ground. The Navunievu community  has mandated that every young adult building their family home in the village should do so upslope rather than on the regularly flooded coastal flat where the existing village is located. Over the next few decades, this will result in the gradual upslope migration of the community, an example of autonomous adaptation. Such creative community-grounded solutions hold great promise for future adaptation on small islands, where they are undertaken inclusively.
