Mangrove planting in Madagascar


Taking down climate change: one mangrove at a time

Madagascar | £0.095 per tree

This trail-blazing project run by Eden Reforestation Projects has reforestation and poverty alleviation at its heart. Mangroves pack some punch when it comes to carbon sequestration but also provide a whole load of other natural benefits such as storm surge protection and vital habitat for many species.

The Madagascar project that we support started in 2007. The project has already planted over 300 million trees and created over 3 million workdays.

  • To date, they have planted over 334 million trees across 8 countries
  • They have created 3.3 million days of work for local communities
  • By 2025 they aim to plant 500 million trees each year

Great for Earth

Madagascar has experienced deforestation on an enormous scale with only 10% of its original forest remaining today. Did you know that approximately 75% of species found in Madagascar are not found anywhere else in the world? This means it is even more important to protect what is left and help to reforest areas that have been destroyed.

Mangroves are important for the climate crisis because estimates suggesting that they sequester carbon at a rate of 2 – 4 times greater than mature tropical forests. Each mangrove tree removes around 308kg of CO2 from the atmosphere over the course of its life-cycle (approximately 25 years).

Mangrove forests also offer numerous other ecosystem services such as natural coastal defences from floods and storm surges, increased biodiversity and sediment reduction.

Planting: A mix of four different mangrove species are planted as well as at least 10% agroforestry trees to provide an additional source of income to the local people. The mangroves are planted directly from propagules, and Eden have discovered that mortality becomes irrelevant as natural regeneration occurs (after the inevitable loss of some propagules). Typically regeneration exceeds 200% of the original number of mangroves planted – we know it’s cool.

Earthly do also contribute a buffer so that if anything were to happen like a tropical storm we have you covered.

Positive for people

Deforestation is often tied to extreme poverty, so Eden Reforestation Projects uses a unique methodology of ‘employ to plant’ in order to target both of these problem areas. This aims to provide fair employment to local people to grow, plant, and guard to maturity native species forest on a massive scale.

Satellite Data

We will be providing live satellite data each month from the projects. Coming Soon.

How does it work?

Undoing climate damage isn't easy. But our powerful partners make it happen.


Eden has partnered with two national parks to restore mangrove estuaries. Written agreements are made to secure the land in perpetuity so deforestation of the newly restored areas does not occur.


Local people are employed by Eden and a variety of propagules are planted.


Mangroves mature, and so does soil quality and water purity leading to increased crop yield and further decrease in extreme poverty.

Why this project?

We chose to partner with Eden Reforestation Projects because we believe in their model of combining tackling poverty with an important climate solution. Tropical forests are listed as 5th on the top 100 climate solutions available today by Project Drawdown.
