Mexican mangroves valuable for fighting climate change

Desert mangroves can store massive amounts of carbon, they are crucial for the coastline ecosystems and human population. A scientific study focused only on Mexican mangroves.

Mangrove studies have often focused in the Indo-pacific region. A recent study published in  Proceedings of the National Academy of Sciences highlights the importance of desert mangroves in the Baja California peninsula in northwest Mexico.

They are of great importance for global carbon storage and sequestration even if they have relatively small areas. The study showed these mangroves have accumulated root peat for nearly 2000 years, they've also been keeping up with rising sea levels for at least 17 centuries.

Desert mangroves can cope with rising sea levels because they've grown on their own root's remains. By doing so they've store  between 900-3,000 MgC/ha of carbon in their sediments which is a similar figure, even higher than their cousins, the tropical mangrove forests.

Desert mangroves in Mexico account for less than 1% of the territory but their belowground sediments store about 28% of the total carbon pool of the region. This explains the need for restauration and conservations of the understated ecosystems.

Overall mangroves protect the coast and habitat structure for the local species and a special role in reducing carbon emission by storing it.

Over half the original global mangrove areas have been lost and approximately 150,000 hectares disappear every year. This kind of studies reassure the need for restoration projects in the remaining mangroves as a measure to cope with climate change.
