Mars Assisted Reef Restoration System

The Challenge

If we don’t act now, 90% of the world’s coral reefs could be gone by 2050. This would have devastating consequences for biodiversity and people worldwide.

Impact Above Water

Our success underwater doesn’t just rejuvenate reefs – it also transforms the lives of people who rely on them.

In 2013, Mars Sustainable Solutions (part of Mars Incorporated) were invited by the community of Pulau Badi – an island in central Indonesia – to help rebuild their heavily damaged coral reef. Together with the island community and scientists from around the world, we started a journey to test and innovate restoration methods for rapidly regrowing coral on a large scale. In 2017, we partnered with the community of Pulau Bontosua to restore their reefs and measure ecological performance.

Our solution - the Mars Assisted Reef Restoration System (MARRS) - is now widely recognised as one of the world’s most effective methods for restoring coral reefs. In areas of extreme damage, barren rubble fields are transformed into thriving ecosystems that can support a diverse range of reef-based livelihoods.

In partnership with local communities, governments, scientists, businesses and NGOs, we are now rebuilding thousands of square metres of coral reef across the world's tropical oceans. Although the threats that reefs face are vast, we are encouraged by our learning and successes so far, and motivated to push forward the field of reef restoration worldwide. Ultimately, we believe that large scale restoration is vital for safeguarding the future of coral reefs and those who rely on them - and we're making it happen today.
