The UK government has agreed to renounce sovereignty over the Chagos Islands and hand it to Mauritius, a significant move that could transform the future of these remote islands in the Indian Ocean. This agreement also paves the way for the potential return of the few remaining people who were forcibly displaced from their homes on the islands decades ago.

A pristine marine paradise

The Chagos Islands, a cluster of islands in the Indian Ocean, are renowned for their exceptional marine biodiversity, featuring vibrant coral reefs and abundant marine life. However, access to these islands has been tightly controlled. With the military base at Diego Garcia occupying a significant portion of the territory, the Chagos Islands—also known as the British Indian Ocean Territory—have remained largely inaccessible, requiring special permits for any travel.

As part of the deal, the UK will retain sovereignty over Diego Garcia, the largest of the islands and the site of a strategically positioned key US-British military base, for an initial period of 99 years, while also paying Mauritius an undisclosed rent. It will create a “resettlement” fund for displaced Chagossians to enable them to return to islands other than Diego Garcia.

A shift in access 

With the recent sovereignty agreement, speculation arises regarding the future of the Chagos Islands as a potential dive tourism destination. If access restrictions are relaxed, this unspoilt paradise could attract divers eager to explore its rich underwater ecosystems. The transition to Mauritian control may open doors for sustainable tourism initiatives, allowing visitors to experience the islands’ natural wonders.

It is hoped that the Chagos Islands can be preserved as a pristine natural reserve, while also providing opportunities for eco-friendly tourism. With the transition of the islands to Mauritian governance, we may soon see changes in regulations to facilitate access for diving tourists and nature enthusiasts alike.

The agreement is still subject to the finalisation of a treaty, but both sides have vowed to move quickly. In addition, the UK will provide a financial support package to Mauritius, including annual payments and a partnership to build infrastructure.
