Blue Carbon Ecosystem For Emissions Mitigation

Bogor, November 30th, 2018

As a common knowledge, mangrove has a large potention to absorb carbon emission. This opinion was support by the new research that was published by Journal Biology Letters by Department of Geography at the NUS Faculty of Arts and Social Sciences. The publication that was published on 24th October said that the countries which has a long coastal area has a large potention to reduce emissions from the fossil fuel.

The coastal vegetation also known as Blue Carbon has an ability to grow quickly and accumulate organic carbon in the water-saturated soil. Besides, blue carbon could store carbon in more efficient way than any other ecosystem, such as tropical rain forest. Although in the global scale the impact of the blue carbon almost nonvisible due to its limited area, in fact 0,42% of the carbon emission was mitigate from this ecosystem

Nigeria, Colombia, and Bangladesh are the example of the importance of the mangrove ecosystem for reducing carbon. These countries is known as the top 50 countries that produce emissions and mangrove was said could mitigate 1% from the national emission in 2014. "In 2014, Colombia has a mangrove area for 1,700 km2 and emit 23 million ton per year. The study shows that mangrove could mitigate almost 26.000 ton per years. If the national emission reduced and the protection and mangrove restoration also conducted the percentage for carbon mitigation could increasing," said Pierre Taillardat, the first author of the study who conducted the research while at the NUS Department of Geography, and in conjunction with the NUS Tropical Marine Science Institute.

Furthermore, he said that this approach could be more interesting if this approach is conducted in Indonesia and Malaysia since both countries has large coastal area. He noted that in Indonesia mangrove could only mitigate 0-4% from national emission due to the mangrove deforestation. However, Assistant Professor Massimo Lupascu from the NUS Department of Geography saida that if the mangrove deforestation could be stopped it could mitigate around 1,6% for Malaysia and 2,6% for Indonesia.

According to the publication of Forestry Research Center by Haruni Krinawati, Indonesia has mangrove cover around 26-29% from the global mangrove landuse. However, the mangrove area keep reducing. In 1990 the area was noted around 3,5 million Ha and covers 99.000 km coastal area, but in 2016 the mangrove area only 2,9 million ha.
