This volume defines and analyzes the Blue Economy, a system that encompasses all the economic activities which are happening in and around the ocean within a sustainable development framework, with focus on countries in Asia. This work is timely, as Blue Economy activities account for a significant share of GDPs in the island and coastal economies in the Asia region, sustaining the livelihoods of one of the largest sections of the world's population. This book, therefore, assesses how the Blue Economy contributes to these livelihoods from economic and ecological perspectives and analyzes the various types of ecosystem services provided, and how these services are regulated and maintained. While most studies of the Blue Economy focus only on the economic aspects, this book provides ample statistical data to demonstrate why ecosystem services should additionally be considered for the estimation and valuation of the Blue economy. The book is primarily meant for researchers, students, and teachers in the fields of environmental and ocean economics, sustainable development, and ecosystem services, and will be of further interest to policymakers and government officials working in matters related to the Blue Economy and sustainability policy.
