Book excerpt: The blue economy is a widely used concept in policy circles; however, people across a wide spectrum have a peripheral understanding of the phenomenon. At the moment, there are several conflicting understandings of the blue economy but no universally accepted definition and veritable measures. Considering the existential importance of the blue economy for the protection of marine environments and sustainability of businesses, there is an urgent need for rigorous conceptual, policy-focused, theoretical, and empirical studies on the subject from multidisciplinary perspectives. Implications for Entrepreneurship and Enterprise Development in the Blue Economy enriches existing definitions of a blue economy with inputs from a multidisciplinary lens and provides veritable measures for evaluating blue economy progression and compliance. Covering topics such as economics, natural resource development, social equity, and sustainability, this reference work is ideal for policymakers, entrepreneurs, managers, oceanographers, marine biologists, scholars, industry professionals, government officials, academicians, researchers, practitioners, instructors, and students.
