The  concept  of  blue  economy  (BE)  has  no  common  definition. Although the idea gained widespread attention with the 2012 UN Conference on Sustainable Development or Rio+20, BE  first  emerged  during  the  1992  Rio  Earth  Summit,  which put a heavy emphasis on promoting the development of a “green economy” (1). The Small Island Developing States (SIDS), highlighting the value of the ocean and its marine economy, started promoting the idea of a BE in response to a global push for a “green” one. Although BE and ‘ocean economy’ are often used synonymously, there are considerable differences between the terms. The ocean economy is an economic activity using the ocean as an input, whereas the BE can be understood as focusing on sustainable ocean economies.
