This book assesses the dynamics, challenges and achievements of the development processes of three Portuguese-speaking Small Island Developing States (PSSIDS) - Cabo Verde, São Tome and Príncipe, and Timor-Leste. Important lessons are drawn from those processes, which are relevant for policymakers, as well as for their bilateral and multilateral development partners, including international organizations such as United Nations or the Community of Portuguese Language Countries. To that end, the book includes contributions to the academic literature about SIDS, an area of research that has been significantly overlooked. The conclusions would be of interest to readers as a lead up to the fiftieth anniversary of their independence.
