London: Mangrove forests could play a crucial role in protecting coastal areas from sea-level rise caused by climate change, a new study has found. Areas without mangroves are likely to widen from erosion and more water will encroach inwards, whereas mangrove regions prevent this effect.


This is likely due to soil building up around their mesh-like roots and acting to reduce energy from waves and tidal currents. The ability of mangrove forest to gradually create a buffer between sea and land occurs even when the area is subjected to potential sea level rises of up to 0.5 mm per year.


Even after sea level rise, the mangroves showed an enhanced ability to maintain an elevation in the upper intertidal zone. Mangroves also have the ability to remove carbon from the atmosphere and protect people from hazards such as tsunami.
