Marine protected areas(MPAs) areprotected areasof the world'sseas,oceans,estuariesor in the US, theGreat Lakes.[2]These marine areas can come in many forms ranging from wildlife refuges to research facilities.[3]MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources.[4]Suchmarine resourcesare 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 disruptingmarine life.In some situations (such as with thePhoenix Islands Protected Area), MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish.[5]The value of MPA to mobile species is unknown.[6]
There are a number of global examples of large marine conservation areas. ThePapahānaumokuākea Marine National Monument,is situated in the central Pacific Ocean, aroundHawaii,occupying an area of 1.5 million square kilometers.[7]The area is rich in wild life, including the green turtle and the Hawaiian monkfish, alongside 7,000 other species, and 14 million seabirds.[8]In 2017 theCook Islandspassed the Marae Moana Act designating the whole of the country's marineexclusive 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 the Cook Islands marine environment".[9]: 355 Otherlarge marine conservation areasinclude those around Antarctica, New Caledonia, Greenland, Alaska, Ascension Island, and Brazil.
As areas of protectedmarine biodiversityexpand, there has been an increase in ocean science funding, essential for preservingmarine resources.[10]In 2020, only around 7.5 to 8% of the global ocean area falls under a conservation designation.[11]This area 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 conservationzones, 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 the fabric of nation states.
Terminology
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/6/6d/Milford_sound_2004.jpg/250px-Milford_sound_2004.jpg)
TheInternational Union for Conservation of Nature(IUCN) defines aprotected areaas:[12][13]
A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associatedecosystem servicesand 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 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.[13]
"Marine protected area (MPA)" is a term for protected areas that includemarine environmentandbiodiversity.
Other definitions by the IUCN include (2010):[14]
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 the enclosed environment.
United States Executive Order 13158 in May 2000 established MPAs, defining them as:[15]
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.
TheConvention on Biological Diversitydefined the broader term ofmarine and coastal protected area(MCPA):[16]
Any defined area within or adjacent to 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 byNOAAto refer to protected areas on the Great Lakes of North America.[2]
History
[edit]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 everysovereign stateto 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 the aftermath of the1992 Earth SummitinRio de Janeiro,an international target was established with the encompassment of ten percent of the world's marine protected areas.
On 28 October 2016 inHobart,Australia,theConvention for the Conservation of Antarctic Marine Living Resourcesagreed to establish the firstAntarcticand largest marine protected area in the world encompassing 1.55 million km2(600,000 sq mi) in theRoss Sea.[17]Other large MPAs are in theIndian,Pacific,andAtlantic Oceans,in certainexclusive economic zonesof Australia and overseas territories ofFrance,theUnited Kingdomand theUnited States,with major (990,000 square kilometres (380,000 sq mi) or larger) new or expanded MPAs by these nations since 2012—such asNatural Park of the Coral Sea,Pacific Remote Islands Marine National Monument,Coral Sea Commonwealth Marine Reserve andSouth Georgia and 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 km2), 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.[18]
Classifications
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/d/d7/Salomons_Atoll_in_the_Chagos.jpg/220px-Salomons_Atoll_in_the_Chagos.jpg)
Several types of compliant MPA can be distinguished:
- A totally marine area with no significant terrestrial parts.
- An area containing both marine and terrestrial components, which can vary between two extremes; those that are predominantly maritime with little land (for example, anatollwould have a tiny island with a significant maritime population surrounding it), or that is mostly terrestrial.
- Marine ecosystems that contain land andintertidalcomponents only. For example, amangrove forestwould contain no open sea or ocean marine environment, but its river-like marine ecosystem nevertheless complies with the definition.
IUCN offered sevencategories of protected area,based on management objectives and four broad governance types.
Cat | IUCNProtected Area Management Categories: |
---|---|
Ia
|
Strict nature reserve Amarine reserveusually connotes "maximum protection", where all resource removals are strictly prohibited. In countries such asKenyaandBelize,marine reserves allow for low-risk removals to sustain local communities. |
Ib
|
Wilderness area |
II
|
National park Marine parksemphasize the protection of ecosystems but allow light human use. A marine park may prohibit fishing or extraction of resources, but allow recreation. Some marine parks, such as those inTanzania,are zoned and allow activities such as fishing only in low risk areas. |
III
|
Natural monuments or features Established to protect historical sites such as shipwrecks and cultural sites such as aboriginal fishing grounds. |
IV
|
Habitat/species management area Established to protect a certain species, to benefitfisheries,rarehabitat,as spawning/nursing grounds forfish,or to protect entire ecosystems. |
V
|
Protected seascape Limited active management, as with protected landscapes. |
VI
|
Sustainable use of natural resources |
Relatedprotected areacategories include the following;
- World Heritage Site(WHS) – an area exhibiting extensive natural or cultural history. Maritime areas are poorly represented, however, with only 46 out of over 800 sites.
- Man and the Biosphere–UNESCOprogram that promotes "a balanced relationship between humans and thebiosphere".Under article 4, biosphere reserves must" encompass a mosaic of ecological systems ", and thus combine terrestrial, coastal, or marine ecosystems. In structure they are similar to Multiple-use MPAs, with a core area ringed by different degrees of protection.[20]
- Ramsar site– must meetcertain criteria for the definition of "Wetland"to become part of a global system. These sites do not necessarily receive protection, but are indexed by importance for later recommendation to an agency that could designate it a protected area.[21]
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 theWorld Conservation Monitoring Centreas:[22]
A collection of individual MPAs operating cooperatively, at various spatial scales and with a range of protection levels that are designed to meet objectives that a single reserve cannot achieve.
At the 2004Convention on Biological Diversity,the agency agreed to use "network"on a global level, while adoptingsystemfor national and regional levels. Thenetworkis a mechanism to establish regional and local systems, but carries no authority or mandate, leaving all activity within the "system".[23]

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), is a 100% no take zone.[24]
Related terms include;specially protected area(SPA),Special Area of Conservation(SAC), the United Kingdom'smarine conservation zones(MCZs),[25]orarea of special conservation(ASC) etc. which each provide specific restrictions.
Stressors
[edit]Stressors that affect oceans include the impact ofextractive industries,marine pollution,and changes to the ocean's chemistry (ocean acidification) resulting from elevatedcarbon dioxidelevels, due to ourgreenhouse gas emissions(see alsoeffects of climate change on oceans).[26]
MPAs have been cited as the ocean's single greatest hope for increasing the resilience of the marine environment to such stressors.[26]Well-designed and managed MPAs developed with input and support from interested stakeholders can conserve biodiversity and protect and restorefisheries.
Economics
[edit]MPAs can help sustain local economies by supporting fisheries and tourism. For example,Apo Islandin thePhilippinesmade protected one quarter of their reef, allowing fish to recover, jump-starting their economy. This was shown in the film,Resources at Risk: Philippine Coral Reef.[27]A 2016 report by theCenter for Development and Strategyfound that programs like theUnited States National Marine Sanctuarysystem can develop considerable economic benefits for communities throughPublic–private partnerships.[28]They can be self-financed through a surrounding "conservation finance area" in which a limited number licenses are granted to benefit from the spillover of the marine protected area.[29]
Management
[edit]Typical MPAs restrictfishing,oilandgasmining and/ortourism.Other restrictions may limit the use ofultrasonicdevices likesonar(which may confuse the guidance system ofcetaceans), 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 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 interritorial waters,exclusive economic zones,or thehigh seas.Thelaw of the searegulates 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 ininternational waters.For example, Italy, France and Monaco in 1999 jointly established a cetacean sanctuary in theLigurian Seanamed thePelagos Sanctuary for Mediterranean Marine Mammals.This sanctuary includes both national and international waters. Both theCBDandIUCNrecommended 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.[30]The following are the most common management systems:
![](https://upload.wikimedia.org/wikipedia/commons/thumb/2/27/Asinara-Island01.jpg/220px-Asinara-Island01.jpg)
Seasonal and temporary management—Activities, most critically fishing, are restricted seasonally or temporarily, e.g., to protect spawning/nursing grounds or to let 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.[32]
Community involvement and related approaches—Community-managed MPAs empower local communities to operate partially or completely independent of 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 the tested cooperation between marine scientists and fishermen in jointly managing coastal marine reserves.[33]
Marine Protected Area Networks
[edit]Marine Protected Area NetworksorMPA networkshave been defined as "A group of MPAs that interact with one another ecologically and/or socially form a network".[27]
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".[27]
Filipino communities connect with one another to share information about MPAs, creating a larger network through the social communities' support.[34]Emerging or established MPA networks can be found inAustralia,Belize, theRed Sea,Gulf of Adenand Mexico.[27]
Future approaches
[edit]To be truly representative of the ocean and its range of marine resources,marine conservationparks should encompass the great variety of ocean geological and geographical terrains, as these, in turn, influence the biosphere around them.[citation needed]As time progresses it would be strategically advantageous to develop parks that include oceanic features such asocean ridges,ocean trenches,island arcsystems, oceanseamounts,ocean plateaus,andabyssal 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?[35]Approximately 64% of the world's oceans are "international waters"and subject to regulations such as theLaw of the Seaand the governance of UN bodies such as theInternational Seabed Authority.[citation needed]The remaining 36% of the ocean is under the governance of individual countries within their Exclusive Economic Zones (EEZs).[citation needed]Some individual national EEZ'scover 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.[citation needed]
One alternative to imposing MPAs on an indigenous population is through the use ofIndigenous Protected Areas,such as those in Australia.
International efforts
[edit]The 17thInternational Union for Conservation of Nature(IUCN) General Assembly inSan Jose,California, the 19th IUCN assembly and the fourth World Parks Congress all proposed to centralise the establishment of protected areas. TheWorld Summit on Sustainable Developmentin 2002 called for
the establishment of marine protected areas consistent with international laws and based on scientific information, including representative networks by 2012.[36]
The Evian agreement, signed byG8 Nationsin 2003, agreed to these terms. The Durban Action Plan, developed in 2003, called for regional action and targets to establish a network of protected areas by 2010 within the jurisdiction of regionalenvironmental protocols.It recommended establishing protected areas for 20 to 30% of the world's oceans by the goal date of 2012. TheConvention on Biological Diversityconsidered these recommendations and recommended requiring countries to set up marine parks controlled by a central organization before merging them. TheUnited Nations Framework Convention on Climate Changeagreed to the terms laid out by the convention, and in 2004, its member nations committed to the following targets;[37]
- By 2006 complete an area system gap analysis at national and regional levels.
- By 2008 address the less represented marine ecosystems, accounting for those beyond national jurisdiction in accordance.
- By 2009 designate the protected areas identified through the gap analysis.
- By 2012 complete the establishment of a comprehensive and ecologically representative network.
"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 the Convention and the 2010 target to significantly reduce the current late ofbiodiversity lossat the global, regional, national, and sub-national levels and contribute to poverty reduction and the pursuit ofsustainable development."[39]
Global goals
[edit]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 ChangeDecision VII/15[40]
The 10% conservation goal is also found inSustainable Development Goal 14(which is part of theConvention on Biological Diversity) and which sets this 10% goal to a later date (2020). In 2017, the UN held theUnited Nations Ocean Conferenceaiming 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 the world's oceans needed to be protected within 3 years.[41][42]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.[41]
Global treaties
[edit]United Nations Convention on the Law of the Sea
[edit]The Antarctic Treaty System
[edit]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-currentAntarctic Treatyto limit large-scale exploitation ofkrillby commercial fisheries. The Convention bound contracting nations to abide by previously agreed upon Antarctic territorial claims and peaceful use of the region while protecting ecosystem integrity south of theAntarctic Convergenceand60 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, 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 the southern shelf of theSouth 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.[43]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 km2(600,000 sq mi) in 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.[44]
National Targets
[edit]Many countries have established national targets, accompanied by action plans and implementations. The UN Council identified the need for countries to collaborate with each other to establish effective regional conservation plans. Some national targets are listed in the table below[45]
Country | Plan of action |
---|---|
American Samoa | 20% of reefs to be protected by 2010 |

United States–California | 29 MPAs covering 18% of state marine area with 243 square kilometres (94 sq mi) at maximum protection. |
The prevalent practice of area-based targets was criticized in 2019 by a group of environmental scientists because politicians tended to protect parts of the oceans where little fishing happened to meet the goals. The lack of fishing in these areas made them easy to protect, but it also had little positive impact.[50]
Regional and national efforts
[edit]The marine protected area network is still in its infancy. As of October 2010, approximately 6,800 MPAs had been established, covering 1.17% of global ocean area. Protected areas covered 2.86% of exclusive economic zones (EEZs).[51]MPAs covered 6.3% of territorial seas.[52]Many prohibit the use of harmful fishing techniques yet only 0.01% of the ocean's area is designated as a "no take zone".[53]This coverage is far below the projected goal of 20%-30%[54][55]Those targets have been questioned mainly due to the cost of managing protected areas and the conflict that protections have generated with human demand for marine goods and services.[56][57]
Africa
[edit]South Africa
[edit]
Themarine protected areas of South Africaare in an area of coastline or ocean within theexclusive economic zone(EEZ) of the Republic ofSouth Africathat is protected in terms of specific legislation for the benefit of the environment and the people who live in and use it.[60]An MPA is a place where marine life can thrive under less pressure than unprotected areas. They are like underwater parks, and this healthy environment can benefit neighbouring areas.[61][62]
There are a total of 42 marine protected areas in the South African EEZ, after consolidation, with a total area of 15.5% of its Exclusive Economic Zone (EEZ). The target was to have 10% of the oceanic waters protected by 2020. All but one of the MPAs are in the exclusive economic zone off continental South Africa, and one is off thePrince Edward Islandsin theSouthern Ocean.Without the large Prince Edward Islands MPA, South Africa has 41 MPAs covering 5.4% of its continental EEZ. This achieves United NationsSustainable Development Goal 14.5for conservation of marine and coastal areas, and theConvention on Biological Diversity(CBD) Strategic Plan for Biodiversity 2011–2020Aichi Target 11.[63][64]
People can take part in a wide range of non-consumptive activities in all of South Africa's MPAs, and some parts of some MPAs are zoned for limited consumptive activities.[62]Some of these activities require a permit, which is a form of taxation.Greater Caribbean

![](https://upload.wikimedia.org/wikipedia/commons/thumb/b/b7/GulfofMexico3D.jpg/220px-GulfofMexico3D.jpg)
TheGreater Caribbeansubdivision encompasses an area of about 5,700,000 square kilometres (2,200,000 sq mi) of ocean and 38 nations. The area includes island countries like theBahamasandCuba,and the majority ofCentral America.The Convention for Protection and Development of the Marine Environment of the Wider Caribbean Region (better known as the Cartagena Convention) was established in 1983. A protocol involving protected areas was ratified in 1990. As of 2008, the region hosted about 500 MPAs.Coral reefsare the best represented.
Two networks are under development, theMesoamerican Barrier Reef System(a longbarrier reefthat borders the coast of much of Central America), and the "Islands in the Stream" program (covering theGulf of Mexico).[65]
Asia
[edit]Southeast Asia is a global epicenter for marine diversity. 12% of its coral reefs are in MPAs. The Philippines have some the world's best coral reefs and protect them to attract international tourism. Most of the Philippines' MPAs are established to secure protection for its coral reef andsea grasshabitats. Indonesia has MPAs designed for tourism and relies on tourism as a main source of income.[27]
China
[edit]China has developed its unique MPA management system, which divides MPAs into two main categories: Marine Natural Reserves (MNRs) and Special Marine Protected Areas (SMPAs).[66][67][68]As of 2016, China has designated 267 MPAs, including 160 MNRs and 107 SMPAs, covering nearly 4% of the sea area.[66]
MNRs are the no-take areas under comprehensive protection that prohibit any kind of resource exploitation.[68]Unlike such traditional MPAs, SMPAs have been established in China since 2002.[66]SMPAs allow the use of marine resources in a supervised and sustainable way, aiming at reducing local development conflicts caused by MNRs (such as the survival of coastal fishermen) and greater matching of national economic development strategies.[66][67][68]Depending on local ecological considerations, SMPAs will subdivide into different functional zones. Areas with rare and endangered species or damaged and fragile environments are strict no-take areas andecological restorationareas, while other areas will be considered sustainable resource use zone for current use and reserved zone for future use.[68]
Despite all the efforts, as China constructs MPA based on administrative hierarchy (national, provincial, municipal, and county), there exist problems of fragmentized division and inconsistent enforcement of MPAs.[68]
Philippines
[edit]ThePhilippineshost one of the most highly biodiverse regions, with 464 reef-building coral species. Due to overfishing, destructive fishing techniques, and rapid coastal development, these are in rapid decline. The country has established some 600 MPAs. However, the majority are poorly enforced and are highly ineffective. However, some have positively impacted reef health, increased fish biomass, decreased coral bleaching and increased yields in adjacent fisheries. One notable example is the MPA surrounding Apo Island.[69]
Latin America
[edit]Latin Americahas designated one large MPA system. As of 2008, 0.5% of its marine environment was protected, mostly through the use of small, multiple-use MPAs.[70]
Mexico designed a Marine Strategy that goes from the years 2018–2021.[71]
Pacific Ocean
[edit]Governments in the "South Pacific network" (ranging fromBelizetoChile) adopted theLima conventionand action plan in 1981. An MPA-specific protocol was ratified in 1989. The permanent commission on the exploitation and conservation on the marine resources of the South Pacific promotes the exchange of studies and information among participants.[70]
![](https://upload.wikimedia.org/wikipedia/commons/thumb/1/10/Tall_Cliffs.jpg/220px-Tall_Cliffs.jpg)
The region is currently running one comprehensive cross-national program, the Tropical Eastern Pacific Marine Corridor Network, signed in April 2004. The network covers about 211,000,000 square kilometres (81,000,000 sq mi).[70]
TheMarae MoanaConservation Park inCook Islandshas many stakeholders within its governance structure, including a variety of Government Ministries, NGOs, traditional landowners, and society representatives.[9]The Marae Moana conservation area is managed through a spatial zoning principle, whereby specific designations are given to specific zones, though these designations may change over time. For example, some areas may allow fishing, whilst fishing may be prohibited in other areas.
The "North Pacific network" covers the western coasts of Mexico, Canada, and the U.S. The "Antigua Convention" and an action plan for the north Pacific region were adapted in 2002. Participant nations manage their own national systems.[70]In 2010–2011, the State of California completed hearings and actions via the state Department of Fish and Game to establish new MPAs.[72]
Indian Ocean
[edit]In exchange for some of itsnational debtbeing written off, theSeychellesdesignates two new marine protected areas in theIndian Ocean,covering about 210,000 square kilometres (81,000 sq mi). It is the result of a financial deal, brokered in 2016 byThe Nature Conservancy.[73][74]
In 2021Australiaannounced the creation of 2 national marine parks in size of 740,000 square kilometers. With those parks 45% of the Australian marine territory will be protected.[75]
Ten countries in the Western Indian Ocean have launched the "Great Blue Wall" initiative, which seeks to create a network of linked MPAs throughout the region. These are generally expected to be underIUCN category IVprotection, which allows for local fishing but prohibits industrial exploitation.[76][77]
Mediterranean Sea
[edit]TheNatura 2000ecological MPA networkin theEuropean Unionincluded MPAs in theNorth Atlantic,theMediterranean Seaand theBaltic Sea.The member states had to define NATURA 2000 areas at sea in theirExclusive Economic Zone.
Two assessments, conducted thirty years apart, of three Mediterranean MPAs, demonstrate that proper protection allows commercially valuable and slow-growing red coral (Corallium rubrum) to produce large colonies in shallow water of less than 50 metres (160 ft). Shallow-water colonies outside these decades-old MPAs are typically very small. The MPAs areBanyuls,Carry-le-Rouetand Scandola, off the island ofCorsica.[78]
- TheMediterranean Science Commissionproposed the creation of eight large, international, MPAs ( "CIESM Marine Peace Parks" ) with the dual benefits of protecting unique oceanographic features and mitigating trans-frontier conflicts[79]
- WWF together with other partners[80]proposed the creation ofMedPan(Mediterranean Network of Marine Protected Areas Managers) which aims to protect 10% of the surface of the Mediterranean by 2020.[81]
A 2018 study published inSciencefound that trawling is more intense inside official EU marine sanctuaries and that endangered fish species such as sharks and rays are more common outside them.[82]
United States
[edit]As of June 2020, 26% of U.S. waters (including theGreat Lakes) were in an MPA. Only 3% of US waters are no-take MPAs. Almost all of the no-take zones are located in two large MPAs in the remote Pacific Ocean,Papahānaumokuākea Marine National MonumentandPacific Remote Islands Marine National Monument.[83]
United Kingdom and British Overseas Territories
[edit]Near half of England's seas are MPAs. Those MPAs only ban in specific places some of the most damaging activities.[84] In 2020, Greenpeace revealed that in 2019 the UK legally allowed industrial boats to fish in the Marine protected area. This point is related to the concern of overfishing, while fishing is an object to the ongoingtrade negotiations between the EU and the UK.Result of those negotiations might replaceCommon Fisheries Policyin the UK.
United Kingdom
[edit]There are a number of marine protected areas around thecoastline of the United Kingdom,known asMarine Conservation Zonesin England, Wales, and Northern Ireland, andMarine Protected Areasin Scotland.[85][86]They are to be found in inshore and offshore waters.[87]In June 2020, a review led byRichard BenyonMP,stated that nearly 50 areas around the UK coastline should become Highly Protected Marine Areas (HPMAs). This would see the banning of dredging, sewage dumping, drilling, offshore wind-turbine construction and catch-and-release sea fishing.[88]
British Overseas Territories
[edit]The United Kingdom is also creating marine protected reserves around severalBritish Overseas Territories. The UK is responsible for 6.8 million square kilometres of ocean around the world, larger than all but four other countries.[89]In 2016 the UK government established the Blue Belt Programme to enhance the protection and management of the marine environment.[90]
TheChagos Marine Protected Areain the Indian Ocean was established in 2010 as a "no-take-zone". With a total surface area of 640,000 square kilometres (250,000 sq mi), it was the world's largest contiguous marine reserve.[91][92]In March 2015, the UK announced the creation of a marine reserve around thePitcairn Islandsin the Southern Pacific Ocean to protect its special biodiversity. The area of 830,000 square kilometres (320,000 sq mi) surpassed the Chagos Marine Protected Area as the world's largest contiguous marine reserve,[93][94]until the August 2016 expansion of thePapahānaumokuākea Marine National Monumentin the United States to 1,510,000 square kilometres (580,000 sq mi).
In January 2016, the UK government announced the intention to create a marine protected area aroundAscension Island.The protected area will be 234,291 square kilometres (90,460 sq mi), half of which will be closed to fishing.[95]The eventual marine park covered 100% of the EEZ.[96]
On 13 November 2020 it was announced that the 687,247 square kilometres (265,348 sq mi) of the waters surrounding theTristan da Cunhaand neighboring islands will become a Marine Protection Zone. The move will make the zone the largest no-take zone in the Atlantic and the fourth largest on the planet.[97][98]

Assessment
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/f/ff/Anguilla_Prickly-Pear.jpg/220px-Anguilla_Prickly-Pear.jpg)
Managers and scientists usegeographic information systemsandremote sensingto map and analyze MPAs. NOAA Coastal Services Center compiled an "Inventory of GIS-Based Decision-Support Tools for MPAs". The report focuses on GIS tools with the highest utility for MPA processes.[103]Remote sensing uses advances inaerial photographyimage capture,pop-up archival satellite tags,satelliteimagery,acoustic data, andradar imagery.Mathematical models that seek to reflect the complexity of the natural setting may assist in planning harvesting strategies and sustaining fishing grounds.[104]Other techniques such as on-site monitoring sensors,crowdsensingvia local people, research and sampling endeavors, autonomous ships and underwater robots (UAV) could also be used and developed.[105][additional citation(s) needed]
Such data can then be used for assessingmarine protection-quality and -extents. In 2021, 43 expert scientists published the first scientific framework version that – via integration,review,clarifications andstandardization– enables coherent evaluation of levels of protection of marine protected areas and serve as a guide for improving, planning and monitoring these such as in efforts towards the 30%-protection-goal adopted as part of the Convention on Biological Diversity's "Post-2020 Global Biodiversity Framework" in December 2022,[106][107]the "Global Deal For Nature"[108]and the UN'sSustainable Development Goal 14.[109][110]
Coral reefs
[edit]Coral reef systems have been in decline worldwide. Causes include overfishing, pollution andocean acidification.As of 2013 30% of the world's reefs were severely damaged. Approximately 60% will be lost by 2030 without enhanced protection.[111]Marine reserves with "no take zones" are the most effective form of protection.[112]Only about 0.01% of the world's coral reefs are inside effective MPAs.[113]
Fish
[edit]MPAs can be an effective tool to maintain fish populations; seerefuge (ecology).The general concept is to create overpopulation within the MPA. The fish expand into the surrounding areas to reduce crowding, increasing the population of unprotected areas.[114]This helps support local fisheries in the surrounding area, while maintaining a healthy population within the MPA. Such MPAs are most commonly used for coral reef ecosystems.
One example is at Goat Island Bay in New Zealand, established in 1977. Research gathered at Goat Bay documented the spillover effect. "Spillover and larval export—the drifting of millions of eggs and larvae beyond the reserve—have become central concepts of marine conservation". This positively impacted commercial fishermen in surrounding areas.[115]
Another unexpected result of MPAs is their impact on predatory marine species, which in some conditions can increase in population. When this occurs, prey populations decrease. One study showed that in 21 out of 39 cases, "trophic cascades", caused a decrease in herbivores, which led to an increase in the quantity of plant life. This occurred in the Malindi Kisite and Watamu Marian National Parks in Kenya; the Leigh Marine Reserve in New Zealand; and Brackett's Landing Conservation Area in the US.[116]
Success criteria
[edit]BothCBDandIUCNhave criteria for setting up and maintaining MPA networks, which emphasize four factors:[117]
- Adequacy—ensuring that the sites have the size, shape, and distribution to ensure the success of selected species.
- Representability—protection for all of the local environment's biological processes
- Resilience—the resistance of the system to natural disaster, such as a tsunami or flood.
- Connectivity—maintaining population links across nearby MPAs.
Misconceptions
[edit]Misconceptions about MPAs include the belief that all MPAs are no-take or no-fishing areas. Less than 1 percent of US waters are no-take areas. MPA activities can include consumption fishing, diving and other activities.
Another misconception is that most MPAs are federally managed. Instead, MPAs are managed under hundreds of laws and jurisdictions. They can exist in state, commonwealth, territory and tribal waters.
Another misconception is that a federal mandate dedicates a set percentage of ocean to MPAs. Instead the mandate requires an evaluation of current MPAs and creates a public resource on current MPAs.[118]
Criticism
[edit]Land use right
[edit]Some existing and proposed MPAs have been criticized by indigenous populations and their supporters, as impinging on land usage rights. For example, the proposed Chagos Protected Area in the Chagos Islands is contested byChagossiansdeported from their homeland in 1965 by theBritishas part of the creation of theBritish Indian Ocean Territory(BIOT). According toleaked diplomatic cables,[119]the UK proposed that the BIOT become a "marine reserve" with the aim of preventing the former inhabitants from returning to their lands and to protect the joint UK/US military base onDiego GarciaIsland.
Climate change
[edit]Oceans are the primarycarbon sinkand have been greatly affected by global warming, especially in recent years. The ability of existing MPA designs to cope with changes in marine biodiversity due to ocean acidification, sea level rise,sea surface temperatureincrease, oxygen reduction, and other marine environmental issues remains questionable.[120][121][122][123][124]Despite differences in species adaptations, warming has affected the habitats of some marine species, such as corals, to move from lower to higher latitudes.[120][121]If MPA assumes a relatively stable ecological environment within the area as before, it may become ineffective when the range of species distribution changes or becomes extensive.[122]Hence, there's need to incorporate the climate change adaptation to the framework.
Displaced fishing effort
[edit]Many fisheries scientists and managers have argued that no-take MPAs may not benefit biodiversity because they displace fishing effort outside the MPA.[125]However, work accounting for displaced fishing effort has suggested that even when the same total amount of fish are caught across the seascape, MPAs can lead to a net biodiversity gain, if sensitive species are present,[126]even when the bycatch species do not fully overlap the distribution of the fished species.[127]However, there are other potential undesirable impacts of displaced fishing effort such as increased cost to fishers.[128]
Other critiques
[edit]Other critiques include: their cost (higher than that of passive management), conflicts with human development goals, inadequate scope to address factors such as climate change and invasive species.[56]
In Scotland, environmental groups have criticised the government for failing to enforce fishing rules around MPAs.[129]
