Darwin Initiative to Strengthen the World’s Largest
Marine Protected Area, Chagos Archipelago,
British Indian Ocean Territory
John Turner, School of Ocean Sciences, Bangor University
& Trustee, Chagos Conservation Trust
CIEEM UKOTS 2016
This talk will cover:
DEFRA funded research project
British Indian Ocean Territory (BIOT) Chagos is an example of a very large MPA and an
internationally important refuge
How it aims to increase strict protection of multiple ocean ecosystems
Importance as Reference Site because its coral reefs have proven to be resilient to climate
change due to the absence of direct human impact
Science to underpin management – some preliminary findings from recent expeditions
Challenges in managing and enforcing a VLMPA
Collaborative project to protect marine
biodiversity of the Chagos Archipelago, funded

VLMPAs in remote UKOTs – are we on the wrong track?
• Race for ‘World’s Largest’ – distraction.
• Undermine aims of Aichi 10% MPA target coverage - 6000 MPAs
total 3.27% but 24 are VLMPAs.
• Detract from MPA initiatives in intensely used areas.
• Criticisms of effectiveness (hard to enforce) representativeness,
(high productivity & relatively unexploited); potential connectivity
(remote), equitable management (benefits not shared).
• Cost per area comparatively low.
• Easy win?

Not everyone supported creation of the MPA
90% Support:
Leading NGOs (IUCN, ZSL,
Greenpeace, FFI) and 270,000
people from 200 nations
supported a Chagos No Take
protected area
And opposition from:
Mauritius, Seychelles, Maldives,
Marine Education Trust (incl some
academics), African Union,
Chagossian Support Association.
Chagos Refugees Group sought
a Judicial Review
http://springtimeofnations.blogspot.co.uk
Major Issues
1.Chagossians:
Foreclose on resettlement, fishing, economic
activity; Chagossians inadequately consulted
2. Mauritius:
Sovereignty claim to EEZ of Chagos; no
consultation, Maldives also disputes EPPZ
3. Poor public knowledge:
Of BIOT UKOT, biodiversity, suspicion of
USA-UK military lateral agreements, concerns
over pollution from US Prepositioning ships
4. Too large an area:
To manage and enforce; loss of income from
fishery licences, & displacement of fishing activity;
concessionary recreational fishery on Diego Garcia
Darwin project aim
To strengthen the Chagos MPA
by providing scientific
knowledge for effective
management, and to develop a
strategy that engages the
support of stakeholders through
outreach, education and
engagement
Legacy: sound management and increased value of what was the world’s
largest no-take Marine Protected Area and a unique and globally important
reference site
Objectives & Outputs 1: Monitoring & Research
To create a permanent monitoring strategy for
coral reefs and island systems to establish
condition on commencement of protection
against which the magnitude and significance
of change/impact can be assessed
Achieved by 3 ship-based expeditions undertaking 17 subprojects to assess biodiversity and productivity at 34 reef
sites and ~50 islands on 6 atolls (including 10 IBAs Important Bird Areas).
Impact:
Data feeding into international databases and scientific
findings have helped shape FCO BIOT’s Interim Chagos
Management Plan; Inform consultations on the Feasibility
of Resettlement, & FCO BIOT Policy Review on
Resettlement, and to address conservation questions from
the Chagos All Party Parliamentary Group, Westminster.
Currently developing 12 BAPs for Chagos species.
Objectives & Outputs 2: To engage Chagossians
through‘Connect Chagos’ outreach programme
Activities aimed at different generations to raise
awareness of value of biodiversity and
importance of conservation.
13 community meetings in UK and Mauritius; 5
family days (965 Chagossians (~50% of
population); 42 ‘Chagossian Ambassador’
graduates from Environmental Training
courses; 12 received advanced training in
swimming, SCUBA diving, habitat restoration;
and 5 awarded places on scientific expeditions
Chagossian representation at Big Ocean
Network Meeting, Hawai’i 2016 (Claudia
Narani)
Multi partner collaboration
Objectives & Outputs 3: To highlight the
significance of Chagos Marine Reserve
internationally as a major step in
conserving marine ecosystems
Achieved through organisation of 3 Chagos Conservation
conferences; 21 international conference presentations
(including keynote at International Marine Conservation
Congress); 17 publications; 6 MSc/ 4 PhD; 3 expedition
reports; 7 expedition blogs; 15 news items; 4 films (inc.
Blue Ocean Film Festival Monaco Finalist) ; 150
biodiversity videoclips; 57 quadcopter aerial videos, 1
London Zoo aquarium exhibit; planned BBC Oceans
production, Support of Google Catlin Seaview initiative

Recent Challenges to MPA
Judicial Review, High Court Aug 2010 - April 2013 on legality of MPA by Chagos
Refugees Group: Deemed Inadmissable.
A Forward Look: Chagos 20/20
Arbitral Tribunal under the UN Convention on the Law of the Sea ruled (March
2015) that the Marine Protected Area declared by the UK is not compatible with
obligations under the Convention to give proper regard to the rights of Mauritius and
is therefore not lawful. The UK must cede Chagos to Mauritius when the
archipelago is no longer required for defence purposes.
Feasibility study for resettlement 2014/2015 found no fundamental legal obstacles
to resettlement. Awaiting Government decision following further consultation.
Supreme Court Appeal Bancoult vs Sec State Foreign & Commonwealth Affairs
June 2015: Deemed Inadmissable.
1966 Exchange of Notes between the UK and the USA: a decision on whether to
extend the arrangement for a further 20 years must be made by 31 December 2016
