46-797: Lihou Reef National Nature Reserve is a former marine protected area covering an area of 8440 km in the Australian Coral Sea Islands Territory that was incorporated into the new Coral Sea Commonwealth Marine Reserve in December 2012. Together with the Coringa-Herald National Nature Reserve , from which it is separated by about 100 km of open ocean, it forms the Coral Sea Reserves Ramsar Site , designated on 16 August 2002, listing it under

92-764: A cetacean sanctuary in the Ligurian Sea named the Pelagos Sanctuary for Mediterranean Marine Mammals . This sanctuary includes both national and international waters. Both the CBD and IUCN recommended a variety of management systems for use in a protected area system. They advocated that MPAs be seen as one of many "nodes" in a network of protected areas. The following are the most common management systems: Seasonal and temporary management —Activities, most critically fishing, are restricted seasonally or temporarily, e.g., to protect spawning/nursing grounds or to let

138-540: A height of 6 m, and Observatory Cay 2 m. Total land area 470,000 m. The islets on the Southern Rim are, from northeast to southwest (clockwise): Only the largest three of the Southern Rim, Anne Cay , Georgina Cay and Nellie Cay , are vegetated. Just northeast of Anne Cay is the Herald Passage into the lagoon. Marine protected area A marine protected area ( MPA ) is a protected area of

184-465: A network of protected areas by 2010 within the jurisdiction of regional environmental protocols .It recommended establishing protected areas for 20 to 30% of the world's oceans by the goal date of 2012. The Convention on Biological Diversity considered these recommendations and recommended requiring countries to set up marine parks controlled by a central organization before merging them. The United Nations Framework Convention on Climate Change agreed to

230-564: A preventive measure or to avoid direct disturbance to individual species. The degree to which environmental regulations affect shipping varies according to whether MPAs are located in territorial waters , exclusive economic zones , or the high seas . The law of the sea regulates these limits. Most MPAs have been located in territorial waters, where the appropriate government can enforce them. However, MPAs have been established in exclusive economic zones and in international waters . For example, Italy, France and Monaco in 1999 jointly established

276-403: A range of protection levels that are designed to meet objectives that a single reserve cannot achieve. At the 2004 Convention on Biological Diversity , the agency agreed to use " network " on a global level, while adopting system for national and regional levels. The network is a mechanism to establish regional and local systems, but carries no authority or mandate, leaving all activity within

322-566: A rapidly reducing species recover. Multiple-use MPAs —These are the most common and arguably the most effective. These areas employ two or more protections. The most important sections get the highest protection, such as a no take zone and are surrounded with areas of lesser protections. Multiple-use MPAs can make use of very diverse fisheries regulations to balance fisheries extraction with nature protection. Community involvement and related approaches —Community-managed MPAs empower local communities to operate partially or completely independent of

368-455: A site should be included in the WDPA. The extent to which each area and the resources within are protected can vary significantly. The largest protected areas – those exceeding an area of 250,000 square kilometres – are listed below in order of total area protected. All are marine protected areas except for Northeast Greenland National Park – which is mostly terrestrial but also has

414-655: Is a 100% no take zone. Related terms include; specially protected area (SPA), Special Area of Conservation (SAC), the United Kingdom's marine conservation zones (MCZs), or area of special conservation (ASC) etc. which each provide specific restrictions. Stressors that affect oceans include the impact of extractive industries , marine pollution , and changes to the ocean's chemistry ( ocean acidification ) resulting from elevated carbon dioxide levels, due to our greenhouse gas emissions (see also effects of climate change on oceans ). MPAs have been cited as

460-722: Is also found in Sustainable Development Goal 14 (which is part of the Convention on Biological Diversity ) and which sets this 10% goal to a later date (2020). In 2017, the UN held the United Nations Ocean Conference aiming to find ways and urge for the implementation of Sustainable Development Goal 14. In that 2017 conference, it was clear that just between 3.6 and 5.7% of the world's oceans were protected, meaning another 6.4 to 4.3% of

506-579: Is equivalent to 27 million square kilometres, equivalent to the land areas of Russia and Canada combined, although some argue that the effective conservation zones (ones with the strictest regulations) occupy only 5% of the ocean area (about equivalent to the land area of Russia alone). Marine conservation zones, as with their terrestrial equivalents, vary in terms of rules and regulations. Few zones rule out completely any sort of human activity within their area, as activities such as fishing, tourism, and transport of essential goods and services by ship, are part of

552-599: Is no defined long-term goal for conservation and ecological recovery and extraction of marine resources occurs, a region is not a marine protected area. "Marine protected area (MPA)" is a term for protected areas that include marine environment and biodiversity . Other definitions by the IUCN include (2010): Any area of the intertidal or subtidal terrain, together with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by law or other effective means to protect part or all of

598-600: Is rich in wild life, including the green turtle and the Hawaiian monkfish, alongside 7,000 other species, and 14 million seabirds. In 2017 the Cook Islands passed the Marae Moana Act designating the whole of the country's marine exclusive economic zone , which has an area of 1.9 million square kilometers as a zone with the purpose of protecting and conserving the "ecological, biodiversity and heritage values of

644-545: The Ramsar Convention as a wetland of international importance. Lihou Reef and its cays were discovered by Lieutenant John Lihou, R.N. , on 23 February 1823. Lihou, then Master of the brig-sloop HMS Zenobia , was on passage from Manila to South America . After a hazardous passage through the reef, the ship departed the Great Barrier Reef via an opening near Murray Islands . On 23 February,

690-586: The Red Sea , Gulf of Aden and Mexico. 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

736-795: The Ross Sea . Other large MPAs are in the Indian , Pacific , and Atlantic Oceans , in certain exclusive economic zones of Australia and overseas territories of France , the United Kingdom and the United States , with major (990,000 square kilometres (380,000 sq mi) or larger) new or expanded MPAs by these nations since 2012—such as Natural Park of the Coral Sea , Pacific Remote Islands Marine National Monument , Coral Sea Commonwealth Marine Reserve and South Georgia and

782-444: The " system ". No take zones (NTZs), are areas designated in a number of the world's MPAs, where all forms of exploitation are prohibited and severely limits human activities. These no take zones can cover an entire MPA, or specific portions. For example, the 1,150,000 square kilometres (440,000 sq mi) Papahānaumokuākea Marine National Monument , the world's largest MPA (and largest protected area of any type, land or sea),

828-603: The Antarctic Treaty and CCAMLR, make up part the broader system of international agreements called the Antarctic Treaty System. Since 1982, the CCAMLR meets annually to implement binding conservations measures like the creation of 'protected areas' at the suggestion of the convention's scientific committee. In 2009, the CCAMLR created the first 'high-seas' MPA entirely within international waters over

874-557: The Convention and the 2010 target to significantly reduce the current late of biodiversity loss at the global, regional, national, and sub-national levels and contribute to poverty reduction and the pursuit of sustainable development ." The UN later endorsed another decision, Decision VII/15, in 2006: Effective conservation of 10% of each of the world's ecological regions by 2010. – United Nations Framework Convention on Climate Change Decision VII/15 The 10% conservation goal

920-497: The Cook Islands marine environment". Other large marine conservation areas include those around Antarctica, New Caledonia, Greenland, Alaska, Ascension Island, and Brazil. As areas of protected marine biodiversity expand, there has been an increase in ocean science funding, essential for preserving marine resources . In 2020, only around 7.5 to 8% of the global ocean area falls under a conservation designation. This area

966-470: The Federated States of Micronesia, Marshall Islands, and Cook Islands who have individual EEZ areas of between 1.9 and 3.5 million km . 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

1012-537: The Great Lakes of North America. The form of marine protected areas trace the origins to the World Congress on National Parks in 1962. In 1976, a process was delivered to the excessive rights to every sovereign state to establish marine protected areas at over 200 nautical miles. Over the next two decades, a scientific body of evidence marked the utility in the designation of marine protected areas. In

1058-643: The Lihou Reefs were sighted. Lihou Reef is the second largest atoll by total size in the Coral Sea , after the Chesterfield Islands (not counting the completely submerged Lansdowne Bank in the easternmost reaches of the Coral Sea). It is U-shaped, with an opening in the south-west. The size of the lagoon is about 100 by 30 km, with an area of 2529 km, making the atoll one of

1104-544: The Ross Sea after several years of failed negotiations. Establishment of the Ross Sea MPA required unanimity of the commission members and enforcement will begin in December 2017. However, due to a sunset provision inserted into the proposal, the new marine park will only be in force for 35 years. Many countries have established national targets, accompanied by action plans and implementations. The UN Council identified

1150-790: The South Sandwich Islands Marine Protected Area . When counted with MPAs of all sizes from many other countries, as of April 2023 there are more than 16,615 MPAs, encompassing 7.2% of the world's oceans (26,146,645 km ), with less than half of that area – encompassing 2.9% of the world's oceans – assessed to be fully or highly protected according to the MPA Guide Framework. Several types of compliant MPA can be distinguished: IUCN offered seven categories of protected area , based on management objectives and four broad governance types. Related protected area categories include

1196-619: The aftermath of the 1992 Earth Summit in Rio de Janeiro , an international target was established with the encompassment of ten percent of the world's marine protected areas. On 28 October 2016 in Hobart , Australia , the Convention for the Conservation of Antarctic Marine Living Resources agreed to establish the first Antarctic and largest marine protected area in the world encompassing 1.55 million km (600,000 sq mi) in

1242-902: 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 km ), and Australia, Russia, UK, and Indonesia (>6 million km ). Some states have very small land areas but extremely large EEZ's such as Kiribati,

1288-538: The enclosed environment. United States Executive Order 13158 in May 2000 established MPAs, defining them as: Any area of the marine environment that has been reserved by federal, state, tribal, territorial, or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein. The Convention on Biological Diversity defined the broader term of marine and coastal protected area (MCPA): Any defined area within or adjacent to

1334-488: The fabric of nation states. The International Union for Conservation of Nature (IUCN) defines a protected area as: A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values. This definition is intended to make it more difficult to claim MPA status for regions where exploitation of marine resources occurs. If there

1380-420: The fishing industry through the revival of fish stocks, as well as job creation and other market benefits via ecotourism . The value of MPA to mobile species is unknown. There are a number of global examples of large marine conservation areas. The Papahānaumokuākea Marine National Monument , is situated in the central Pacific Ocean, around Hawaii , occupying an area of 1.5 million square kilometers. The area

1426-504: The following; While "area" refers to a single contiguous location, terms such as " network ", " system ", and " region " that group MPAs are not always consistently employed." System " is more often used to refer to an individual MPA, whereas " region " is defined by the World Conservation Monitoring Centre as: A collection of individual MPAs operating cooperatively, at various spatial scales and with

1472-505: The governmental jurisdictions they occupy. Empowering communities to manage resources can lower conflict levels and enlist the support of diverse groups that rely on the resource such as subsistence and commercial fishers, scientists, recreation, tourism businesses, youths and others. Mistrust between fishermen and regulating authorities is of central importance there, and needs to be addressed. Recent evidence from regions like Scandinavia, Spain, Portugal or Canada reveals success stories based on

1518-528: The largest in the world. Nevertheless, the total land area of the islets and cays is little more than a square kilometre. The lagoon is up to 60 m deep. The reserve contains 18 islets and cays , 9 each on the Northern Rim and the Southern Rim, ranging in size from 5,000 to 168,000 m. Total land area 560,000 m; the islets on the Northern Rim are, from southwest to northeast (clockwise): Only Lorna Cay and Turtle Islet are vegetated. Turtle Islet reaches

1564-418: The marine environment, together with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by legislation or other effective means, including custom, with the effect that its marine and/or coastal biodiversity enjoys a higher level of protection than its surroundings. An apparently unique extension of the meaning is used by NOAA to refer to protected areas on

1610-615: The need for countries to collaborate with each other to establish effective regional conservation plans. Some national targets are listed in the table below List of largest protected areas The World Database on Protected Areas (WDPA) is compiled and managed by the World Conservation Monitoring Centre , an executive agency of the United Nations Environment Programme . It uses the IUCN and CBD definitions of protected areas to determine whether

1656-549: The ocean's single greatest hope for increasing the resilience of the marine environment to such stressors. Well-designed and managed MPAs developed with input and support from interested stakeholders can conserve biodiversity and protect and restore fisheries . MPAs can help sustain local economies by supporting fisheries and tourism. For example, Apo Island in the Philippines made protected one quarter of their reef, allowing fish to recover, jump-starting their economy. This

1702-476: 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,

1748-562: The region while protecting ecosystem integrity south of the Antarctic Convergence and 60 S latitude . In so doing, it also established a commission of the original signatories and acceding parties called the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to advance these aims through protection, scientific study, and rational use, such as harvesting, of those marine resources. Though separate,

1794-629: The southern shelf of the South Orkney Islands . This area encompasses 94,000 square kilometres (36,000 sq mi) and all fishing activity including transshipment, and dumping or discharge of waste is prohibited with the exception of scientific research endeavors. On 28 October 2016, the CCAMLR, composed of 24 member countries and the European Union at the time, agreed to establish the world's largest marine park encompassing 1.55 million km (600,000 sq mi) in

1840-477: The spillover of the marine protected area. Typical MPAs restrict fishing , oil and gas mining and/or tourism . Other restrictions may limit the use of ultrasonic devices like sonar (which may confuse the guidance system of cetaceans ), development, construction and the like. Some fishing restrictions include "no-take" zones, which means that no fishing is allowed. Less than 1% of US MPAs are no-take. Ship transit can also be restricted or banned, either as

1886-403: The terms laid out by the convention, and in 2004, its member nations committed to the following targets; "The establishment by 2010 of terrestrial and by 2012 for marine areas of comprehensive, effectively managed, and ecologically representative national and regional systems of protected areas that collectively, inter alia through a global network, contribute to achieving the three objectives of

1932-448: The tested cooperation between marine scientists and fishermen in jointly managing coastal marine reserves. Marine Protected Area Networks or MPA networks have been defined 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

1978-817: The use of Indigenous Protected Areas , such as those in Australia. 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. The World Summit on Sustainable Development in 2002 called for the establishment of marine protected areas consistent with international laws and based on scientific information, including representative networks by 2012. The Evian agreement, signed by G8 Nations in 2003, agreed to these terms. The Durban Action Plan, developed in 2003, called for regional action and targets to establish

2024-789: The world's seas , oceans , estuaries or in the US, the Great Lakes . These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life . MPAs can provide economic benefits by supporting

2070-616: The world's oceans needed to be protected within 3 years. The 10% protection goal is described as a "baby step" as 30% is the real amount of ocean protection scientists agree on that should be implemented. On 7 April 1982, the Convention on the Conservation of Antarctic Marine Living Resources (CAMLR Convention) came into force after discussions began in 1975 between parties of the then-current Antarctic Treaty to limit large-scale exploitation of krill by commercial fisheries. The Convention bound contracting nations to abide by previously agreed upon Antarctic territorial claims and peaceful use of

2116-590: Was shown in the film, Resources at Risk: Philippine Coral Reef . A 2016 report by the Center for Development and Strategy found that programs like the United States National Marine Sanctuary system can develop considerable economic benefits for communities through Public–private partnerships . They can be self-financed through a surrounding "conservation finance area" in which a limited number licenses are granted to benefit from
