Why care

Mangrove forests are among the most biologically important ecosystems on the planet. They mitigate climate change, protect coastlines and provide livelihoods, but they are being lost at an alarming rate.

The work

Leo Thom is Creative Director at Mangrove Action Project and Conservation Filmmaker. His works involves:

  • Setting up and implementing monitoring and training workshops to give the local communities in Madagascar the ability to strengthen and protect their mangrove forests.

  • Promoting and teaching the ‘Community-Based Ecological Mangrove Restoration’ (CBEMR) technique, a successful mangrove planting method that works with mangrove ecology and biology by mimicking natural processes. 

  • Uses the restoration programs as an education activity which help build positive awareness and knowledge amongst coastal communities, NGOs, governments and the media.


  • Has been working with coastal communities in Thailand since 2009 to restore mangroves along the Andaman coast. 

  • Nai Nang Village have developed an apiculture group to support their mangrove conservation efforts, taking pressure off existing mangroves and providing an alternative income. 

  • Are working to spread the methodology of CBEMR so others can help improve mangrove restoration efforts. Following a CBEMR Training conducted with local NGOs in El Salvador, over 6,000 ha of mangrove has been restored with local communities.
