Archipelagic Economies examines the geographic dispersion of Pacific islands' populations and its socio-economic consequences. The study presents new measures of geographic dispersion that show the uniqueness of the Pacific island countries' human geography. It offers a closer look at the socio-economic situation of dispersed island populations, the internal movement of people that connects communities across islands, and the political economy landscape that underpins spatial economic policy decisions. A particular focus of this book is on policy options for dealing with the challenges faced by many outer islands - limited economic opportunities, costly service delivery, obstacles to connectivity by sea, air, and ICT, and urbanization in an era of climate change.
