From the concept introduced by the Dutch entrepreneur Gunter PAULI in 2004 — to promote a global approach of sustainability, circularity, proximity, etc. in the use of earth resources — to the World Wildlife Fund's set of principles for the economic development of the ocean, the notion of Blue Economy covers a wide range of topics whose the common ground is sustainability.   

To clarify the purpose, the OO University defines the "Blue Growth" similarly to the European Union:

Blue Growth is the sustainable growth of the marine and maritime sectors as a whole, mutually balanced. Seas and oceans are drivers for socio-economy and have great potential for innovation and growth. The main concerned sectors are aquaculture, coastal tourism, marine biotechnology, ocean energy and seabed mining.

With a sustainable development perspective, fishing could be designed as a way to develop the local territory with a balanced exploitation of local halieutic resources, the provision of local employment, the offering of quality food by local suppliers, etc. Similarly, coastal tourism could be developed within scale limits avoiding congestion of sites, pollution, land degradation, etc. caused usually by mass tourism. The exploitation of mineral, biological and other ocean resources should be made with a careful view ensuring the long-term sustainability of the whole oceanic systems. 

Operational foresight is a powerful tool to clarify the understanding of these issues for all concerned actors (businesses, public authorities, consumers, etc.), to anticipate disruptions and opportunities and to elaborate long-term, sustainable solutions (new business models, legal frameworks, coordinated concrete actions, etc.) considering people as well as economy.
