Mismanagement of Ocean Governance?

Displaced Chagossians, as well as Mauritians, were excluded from decision making and denied acess to marine resources...

  • Violation of the participation and fairness principles.
  • US military base undermines credibility of the no-take designation.
  • Conservation goals were prioritized at the expense of social justice and the inclusivity of native/ coastal based communities.

Achieved
  • Reduced illegal fishing;
  • Protected one of the most intact coral reefs in the world;
  • Served as an international scientific benchmark;
  • It implemented naval patrols, electronic licensing;
  • Strengthened regional cooperation;
  • Recent sovereignty agreement with Mauritius.

Results :

  • Exclusion of the Chagossians,
  • Severe episodes of coral bleaching;
  • Persistent cases of illegal fishing;
  • Lack of transparency in the MPA's creation.
