Sea Economy is essential to the future welfare and prosperity of humankind. It is the main source of food, energy, minerals, health, leisure and transport upon which hundreds of millions of people depend. However, the maritime industry landscape is poised to undergo a profound transition. Long considered the traditional domain of shipping, fishing and - since the 1960s - offshore oil and gas, new activities are emerging that are reshaping and diversifying maritime industries. Realizing the full potential of the sea economy will demand responsible sustainable approaches to its economic development.
