Is the race for vast remote MPAs taking us down the wrong track?

Targets for marine conservation have been important since 1998, when 1605 scientists from around the world signed a call for governments to protect 20% of the world’s seas from all threats by 2020. Since then, there have been several formal targets for MPA coverage, most significantly the Convention on Biological Diversity’s ‘Aichi target’ that at least 10% of the world’s seas should be effectively conserved through systems of MPAs by 2020. The achievement of such targets has increasingly been progressed through the designation of giant MPAs, often surrounding islands in remote oceans, i.e. vast remote MPAs. The first VRMPA was the 340,000 km2 Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve, designated in 2000, as part of Bill Clinton’s departing environmental legacy, and larger than all of America’s national parks combined. This VRMPA was later included in the Papahānaumokuākea Marine National Monument, this 2006 designation by George Bush building on the previous one. Initially open to bottom trawling, all fishing throughout the PMNM was banned in 2011, as whilst ‘bigger is better’, it is also considered that ‘no-take is best’. The race was on.

There have since been many more designations in the race to declare the largest MPA in the world and add to the list of ‘flagship’ VRMPAs. This race has been enthusiastically supported by conservation campaign groups and donors, and many governments have joined in, all keen to gain the green credentials associated with VRMPAs. This has led to ~62% of global MPA coverage being down to just 24 such designations (all >100,000 km2) amongst a total of over 6,000 MPAs, which all together cover only 3.27% of the global marine area (Boonzaier and Pauly 2016), so without remote VLMPAs we would be even further from achieving the 10% target. A recent paper on the effectiveness of MPAs (Edgar et al. 2014) provides scientific evidence to support this race, as it found that there are five key features of MPAs that promote the effective achievement of conservation outcomes – being large, well enforced, no-take, old and isolated from fished areas. However, a related paper (Devillers et al. 2015) argues that MPAs are increasingly biased towards such isolated areas that are residual to commercial use and therefore have not yet been heavily exploited. The remoteness of such isolated residual areas means that they can often be closed with relatively few political costs, as they tend to be in overseas territories where few, if any, mainland voters live, and with relatively minor economic costs, as commercial exploiters tend to be incoming fishing vessels from other countries:

From the perspective of national governments, it is clear that VRMPAs are win-win, in that they gain green credentials and contribute to each country’s Aichi target. Why go through the politically and economically expensive process of designating relatively small MPAs around the mainland when you can designate vast MPAs in overseas territories with minimal costs and many gains? From the perspective of conservation campaigners and donors, it is clear that VRMPAs deliver high profile benefits in that they safeguard large areas of relatively pristine seas from increasingly pervasive fishing industry pressures. The persuasiveness of such rationales is evident in the increasing number of VRMPAs and proportion of global MPA coverage that they represent.

There are, however, several major problems with this trend, as the Aichi target is about much more than total coverage:

At least 17% of terrestrial and inland water, and 10% of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services, are conserved through effectively and equitably managed, ecologically representative and well connected systems of protected areas and other effective area-based conservation measures, and integrated into the wider landscape and seascape[ by 2020] – 10th Conference of the Parties (COP10) to the Convention on Biological Diversity (CBD), Aichi, Japan, 2010.

The target states that MPAs must be effective in enforcing restrictions on impacting activities, particularly fishing, but vastness and remoteness pose major enforcement challenges. Whilst emerging satellite surveillance technology can help detect illegal fishing vessels, there are still challenges in detaining such vessels through interception by a fisheries patrol vessel, which are very expensive to operate in such vast distant areas, or remotely gaining enough evidence to secure a guilty verdict in court. Detection alone is not enough, vessels must be detained, sufficient evidence gathered, successful prosecutions gained and penalties applied that are sufficient to deter other fishers (Jones 2014: 154-155 ). There are concerns that the pace at which VRMPAs are being designated exceeds the pace at which enforcement capacity is being developed, and that some VRMPAs are ‘paper parks’ that provide only an illusion of marine conservation.

The Aichi target also specifies that MPA systems must be representative, in that they should protect typical examples of species and habitats in each of the world’s marine bioregions, and well connected, in that the MPAs should be close enough together to enable ecological processes to connect between them. A focus on relatively few VRMPAs in remote and residual areas will not achieve such representative and well connected networks, as MPA coverage will remain patchy and the gaps too large, i.e. MPAs will be separated by large expanses of unprotected ocean. Whilst inshore ‘metropolitan’ seas with a higher number of users represent a challenge, such seas need to be included in MPA networks if they are to be representative and well connected. It could also be argued that whilst such MPAs may have to be smaller and provide for fishing activities on which people depend for their livelihoods, perhaps including small no-take zones, it is important to also focus conservation efforts on areas that are under pressure and on which people rely. Marine conservation should be as much about promoting sustainable use in metropolitan seas as it is about promoting no use in remote, residual seas. This is particularly important given that a recent analysis shows that 58% of the world’s coral reefs are within 30 minutes travelling time of the nearest human settlement (Maire et al 2016), i.e. more than half the world’s corals could be considered as ‘metropolitan’ and could be neglected if the focus is on vast, remote, no-take MPAs.

Last but certainly not least, the Aichi target states that MPA networks should be equitably managed, in that the costs and benefits of MPAs should be fairly distributed. Whilst VRMPAs tend to be in areas where only a relatively small number of people live, such people do tend to have a high dependence on marine resources, including for commercial and traditional customary use, so it could be unfair to close most or all of the exclusive economic zone to all extractive activities. Such people may be politically remote but their rights must not be marginalised by VRMPAs.

So, the race to designate MPAs that are vast and remote could be slowing progress towards achieving the Aichi target for effective, representative, well-connected and equitable networks of MPAs, or even taking us down the wrong track. It is clear that in the same way that MPAs need to conserve a diversity of species, MPA networks need to include a diversity of different types of MPA, including VRMPAs, but also including smaller MPAs in metropolitan seas that promote sustainable use. It is important that the race towards VRMPAs does not divert attention, resources and political will away from the other types of MPA that are necessary for fulfilling marine conservation targets.
