We help develop the biodiversity of marine ecosystems in Indonesia, protecting and repopulating damaged reef areas through coral reefs conservation programs such as coral reef restoration projects.

Thanks to the construction of unique artificial reefs, dedicated to the rehabilitation of coral reefs in damaged areas, we make possible the return of lost biodiversity in this environment.

The reef-building corals are real carbon sink, giving the project a global scale, allowing the reduction of the concentration of atmospheric carbon dioxide present.


The assessment of the objective will be done thanks to the biological monitoring of the zone on the means and the long run.

The project is organized in three phases. First preliminary study that evaluates the state of the area determines the positioning of the area of rehabilitation and its environmental impact. Then comes the phase of design, manufacture and disposal of structures and finally the monitoring of the biodiversity over five years.

The project’s success depends on several factors:

  • The site selection take into account the nature of the biodiversity, the surrounding natural habitats and prevailing currents,
  • he structure and size of artificial reefs must meet certain specifications,
  • Consultating local stakeholders (fishermen, divers, service state and local, National Park, associations and the general public) is essential.


Our artificial reefs are designed primarily for the purpose of providing habitat for marine wildlife, making it possible to re-grow faster ecosystem and a solid substrate for corals to grow in the best conditions possible. We use various restoration techniques and different substrates to be the most suitable possible to the area identified. It creates, protects and regenerate the local ecosystem, meeting the objectives of protecting and valuing biodiversity of coral reef ecosystems:

  • Regeneration of local biodiversity, particularly in areas where protected species are.
  • Buffer coastal habitats aginst floods and erosion.
  • Substrate creation, important for the colonization of marine life
  • Fisheries enhancement
  • Support of artisanal fishing activities
  • Research Tool
  • Creates zones for recreational diving

Artificial reefs are designed with the collaboration of our marine biologists, architects, engineers and designers, optimized for the development of biodiversity. Artificial reefs are colonized by pioneer species, providing an alternate environment to greater biodiversity. These are places where juveniles can better protect themselves against predators.


We have established a locally managed marine protected area (LMMA). It is a coastal water zone that is fully managed at the local level by coastal communities, landowner groups, partner organizations, and/or government representatives who are based in the immediate area. Using an LMMA approach, coastal communities are reviving traditional practices that have been used in their culture for many generations.

Physical protection of the non-take zone on the reef restoration area is ensured by the installation of a 250 metre buoy line (one buoy every 10 metres). The water line is firmly attached and gives a well defined visual limit. It makes it possible to signal the monitoring zones and to dissuade the boats wishing to cross it. These measures are essential to ensure effective protection and are accompanied by mediation so that all users can understand the issues of the program. No more boats in the area are allowed to throw ink or fish. These pressures on coral reefs are now absent.


  • Regeneration of lost biodiversity.
  • Preservation and regeneration of an important source of food for the village depends on it.
  • Carbon sequestration in the limestone skeleton of reef-building corals.
  • Preservation of marine ecosystems and endemic and endangered species.


  • Empowering the sustainable management of their environment.
  • Social cohesion and food sovereignty.
  • The environmental and economic impacts have the effect of improving the comfort of life in local communities.
  • The dynamics of the conservation program also encourages the development of outreach programs to local schools.
  • The success of this program will be a model for other villages in the same situation.


  • Creating local and sustainable jobs.
  • Increasing and diversifying income.
  • Complementary activities, corals contribute to the regeneration of the biomass which allows the development of sustainable fisheries for the village.
  • Potential development of activities such as eco-tourism, is also a tool to raise awareness of marine conservation for tourists.
  • Preserving and regenerating fish stocks, that will improve fishery resources.



Pulau Hatamin Coral Sanctuary: Located northwest of Flores in Indonesia, the area was officially declared Marine Protected Area in June 2014 by the Indonesian government after our request. 


Overfishing and dynamite fishing have affected the ecological balance of local coral reef ecosystems and disrupted the food chain resulting in ecological and socio-economic impacts.


By developing a community participatory program, local fishermen will help significantly reduce pressures on marine biodiversity. This will result in improved comfort of life in local communities. In addition, the combination of environmental, economic and social perspectives will result in regeneration of local fish stocks, allowing the rest of the village to continue fishing, this time permanently.

In 2018:

  • 26,000 corals transplanted
  • A Marine Protected Area of 629 Ha created
  • 15 local jobs created
