Protecting Mangrove Forests in Mombasa: World Wetland Day 2026

Mangroves – a specific type of coastal wetland characterised by salt-tolerant trees and shrubs in the intertidal zone – are vitally important in efforts to protect against climate change, as well as providing the foundations for the economic success of coastal communities. 

Acting as natural barriers against erosion, mangrove forests can store up to twice their biomass in carbon. In fact, mangrove forests sequester carbon at rates two to four times higher than those of mature tropical forests. 

This high rate of sequestration makes the destruction of mangroves incredibly environmentally damaging. Despite accounting for just 0.7% of total global tropical forest area, emissions from the degradation of mangroves can account for up to 10% of total carbon emissions from deforestation. 

But wetland areas (including mangroves) are currently being destroyed three times faster than forests. 35% of the world’s wetlands have disappeared since 1970, with 90% of global wetlands degraded. 

In Kenya, half of all the country’s mangrove forests have been destroyed in the last 50 years, with a consistent overexploitation of the resource causing irreparable damage. 

This extends beyond climate impact, fundamentally altering the livelihoods of coastal communities, including those in Mombasa. Wetlands, including mangroves, are amongst the most productive ecosystems on earth. Filtering water, regulating floods, controlling soil erosion, and providing a critical habitat for aquatic species. 

Mangrove ecosystems provide a nursery, feeding, and breeding habitat for fish, prawns, and crabs. Their destruction negatively impacts the economic opportunities for fishermen in Mombasa, with a direct bearing on their catch and the abundance of seafood.

The strong connection between ecology and economy underpins all of Haller’s work in Kenya and around the world. 

We’ve worked closely with coastal communities in Mombasa to provide education on the importance of conserving Mangrove forests, as well as organising beach and forest clean ups to protect these environments.
