Mangroves can help countries mitigate their carbon emissions







A study by researchers from the Department of Geography of the National University of Singapore (NUS) indicates that nations with long coasts could expand these ecosystems to further offset fossil fuel emissions. These findings have been published in the journal of the Royal Society 'Biology Letters'.



Given that the recent Paris Agreement established an objective for all nations to become carbon neutral in the future, the use of these natural ecosystems could help achieve this goal.



Coastal vegetation, known as a "blue carbon" ecosystem, can grow rapidly and has the capacity to accumulate organic carbon in the soil saturated with water that surrounds it. Therefore, vegetation such as mangroves can store carbon more efficiently, in a way that other ecosystems, such as tropical forests, can not.



On a global scale, the impact of blue carbon decreases due to the limited range of these coastal regions. In fact, only 0.42% of the global carbon emissions induced by man in 2014 were mitigated by these ecosystems. However, for countries with extensive coasts, moderate carbon emissions and limited deforestation, these habitats could be effective in counteracting fossil fuel emissions caused by human activities.

The study revealed that in Nigeria, Colombia and Bangladesh, which are among the 50 largest fossil fuel emitting countries in the world, only mangroves mitigated more than 1% of their national carbon emissions in 2014, according to the NUS information collected by DiCYT.



"We think that this approach would be interesting for countries like Indonesia and Malaysia, due to its extensive coastal lines occupied by mangroves. However, the high rate of deforestation of mangroves in both countries is actually reducing the importance of this natural carbon sequestration process, "says Pierre Taillardat, first author of the study.



The results suggest that the conservation and restoration of blue carbon ecosystems is a direct way to mitigate the effects of climate change, as well as other benefits that these ecosystems provide to people. The finding that mangroves and other blue carbon ecosystems are efficient carbon harvesters has prompted scientists behind the study to boost their protection.



"The restoration of mangroves does not have to be difficult. If done correctly, it only takes a few years to start growing a forest of new trees. By creating conditions similar to those found in a natural forest, it is possible to expand mangrove habitats and absorb more carbon, "explained Associate Professor Daniel Friess. (Source: DICYT)
