The book traces how threats to the livelihoods of island households, especially for those literally and metaphorically living on the edge, are linked to overseas decisions, events and shocks, ranging from cyclones to migration policies, resort chains, drug trafficking, warfare, and commodity supply chains. It also shows how enthusiasm for a secure blue economy has required new approaches to national development, regional cooperation and global statecraft, particularly as China exported its maritime Belt and Road Initiative. As a new geopolitical order emerges and climate change continues, this book provides crucial insights into how small island states are building effective development pathways.
