The mangroves - an ecosystem in the fight against climate change

They are true artisans of life, growing in salty water and under scorching sun, protecting the coasts from erosion, providing a diverse habitat for animals and humans and, by the way, they are also incredibly efficient at storing CO2. In a previous article we have already explained this to you, why we plant trees in the first place. Today we are talking about the stars of our reforestation project: the mangrove trees.

A small profile of the mangrove

The mangrove refers to a whole ecosystem consisting of various types of shrubs and trees. Mangrove forests line the tropical coasts of the world, protecting the land from erosion by the rough sea. The people on the land also benefit from this, because the mangroves are less endangered by tidal waves. In the branched roots, land and sea organisms share the habitat. For many sea dwellers, the mangrove ecosystem is the nursery, where various species of fish and crabs spawn. Further up, in the crowns of the mangrove trees, water birds, reptiles and mammals feel comfortable. Besides the tropical rainforest and coral reefs, mangrove forests are the most productive ecosystems on earth. Pretty impressive, we think.

Emission compensation through trees

The idea of offsetting emissions by trees is not new. However, as a company we have asked ourselves how we can most effectively offset emissions by reforestation. Which tree binds a lot of CO2, is easy to plant and does not exceed the budget? Fortunately, mangrove trees fulfil all these conditions and that is why we have been contributing to the reforestation of the mangroves since March 2018.

Unfortunately the area of mangrove forests shrinks by 2% every year. That doesn't sound very dramatic at first, but a whole quarter of the original mangrove forests have already disappeared. This not only threatens the habitat for humans and animals, but also releases the stored, climate-damaging gases during deforestation.

Facts, please! What mangroves do

So that you can get a better idea of how efficient mangroves actually are, we would like to enumerate a few facts regarding the CO2 storage. Every year, one hectare of mangrove forest can extract between 1.5 and 3 tons of CO2 from the atmosphere. One hectare is a little bit bigger than a standard football field and one ton of CO2 corresponds to the emissions of a car if you drive from Hamburg to Lisbon and back with it alone. Mangroves are simply incredibly efficient, almost a little underestimated CO2 sinks. In total, the mangrove forests of the earth store about 20 billion tons of CO2 per year and this on an area that does not even correspond to 1% of the area of the rainforest.

We have already achieved this with the reforestation of mangroves

We from the nu company support the Eden Reforestation Project, a network for the reforestation of the destroyed mangrove forest in Madagascar. Through your support we have already planted over half a million trees. This is an area slightly larger than 50 football fields. If that doesn't give you courage!
