People across the world have diverse economic, sociolegal, institutional, social and cultural relationships with the ocean—both its littoral zones and the open sea spaces through which people have traditionally navigated, migrated, fished, traded, played and sought solace, spiritual enlightenment, adventure, material enrichment, social identity, cultural expression, artistic inspiration or good health. These relationships are reflected in formal and informal institutions (polices, laws, social norms) that regulate many of these activities, including those that regulate access to resources. These institutions represent a series of prior claims and rights to the use and enjoyment of the ocean by coastal and maritime societies.
