as "A group of MPAs that interact with one another ecologically and/or socially form a network". These networks are intended to connect individuals and MPAs and promote education and cooperation among various administrations and user groups. "MPA networks are, from the perspective of resource users, intended to address both environmental and socio-economic needs, complementary ecological and social goals and designs need greater research and policy support". Filipino communities connect with one another to share information about MPAs, creating a larger network through the social communities' support. Emerging or established MPA networks can be found in Australia, Belize, the Red Sea, Gulf of Aden and Mexico. Future approaches To be truly representative of the ocean and its range of marine resources, marine conservation parks should encompass the great variety of ocean geological and geographical terrains, as these, in turn, influence the biosphere around them. As time progresses it would be strategically advantageous to develop parks that include oceanic features such as ocean ridges, ocean trenches, island arc systems, ocean seamounts, ocean plateaus, and abyssal plains, which occupy half the earth's surface. Another factor that will influence the development of marine conservation areas is ownership. Who owns the world's oceans? Approximately 64% of the world's oceans are "international waters" and subject to regulations such as the Law of the Sea and the governance of UN bodies such as the International Seabed Authority. The remaining 36% of the ocean is under the governance of individual countries within their Exclusive Economic Zones (EEZs). Some individual national EEZ's cover very large areas, such as France and USA (>11 million km2), and Australia, Russia, UK, and Indonesia (>6 million km2). Some states have very small land areas but extremely large EEZ's such as Kiribati, the Federated States of Micronesia, Marshall Islands, and Cook Islands who have individual EEZ areas of between 1.9 and 3.5 million km2. The national EEZ's are the ones where governance is easier, and agreements to create marine parks are within national jurisdictions, such as is the case with Marae Moana and the Cook islands. One alternative to imposing MPAs on an indigenous population is through the use of Indigenous Protected Areas, such as those in Australia. International efforts The 17th International Union for Conservation of Nature (IUCN) General Assembly in San Jose, California, the 19th IUCN assembly and the fourth World Parks Congress all proposed to centralise the establishment of protected areas.
