Science publishes alert from Maranhão about the role of Brazilian mangroves in climate change |  Maranhão

A group of Brazilian scientists have published in one of the world’s leading scientific journals: A Science. In the letter, released on March 17, 20 scientists, including several Maranhão, warned of the need to conserve the country’s mangroves in the fight against climate change.

The study indicates that a file Brazil is the second largest country in the world in terms of mangrove forest areaIt is second only to Indonesia. The country also has the largest continuous area of ​​mangroves, which lie between the coasts of Barra and Maranhão. The ecosystem serves as food security for fish and birds, as well as am natural carbon dioxide “flash”.

“Our publication aims to draw the attention of the international community to the great capacity that Brazilian mangroves have to sequester and store carbon dioxide (the main greenhouse gas produced by human activities) in ‘clay’ (so-called random mangrove soils),” explains Denilson Bezerra, researcher at Department of Oceanography and Lake Science at the UFMA.

Forest care but with an emphasis on mangroves

According to scientists, Brazilian mangroves alone collect 3% to 8% of the carbon on the planet. As a solution, the group proposes creating a government monitoring program, using police force, to prevent deforestation in mangrove areas.

“The inclusion of Brazilian mangroves in the National Strategy to Reduce Emissions from Deforestation and Forest Degradation (REDD) can make Brazil an international reference in the fight against climate change. As we argue in our publication, the Brazilian government establishes and implements an official program for Constant monitoring of changes in mangrove areas (as in the Amazon and Cerrado, for example), which do not currently exist.”

The message also reinforces the warning that new changes in legislation may reduce the protection of this ecosystem, such as 2020 resolutions, The National Environment Council (Kunama), which has imposed restrictions on deforestation and occupation in conservation areas with local vegetation, such as sandbanks and mangroves. In 2021, resolutions are canceled after A decision of the Federal Supreme Court (STF) ruled the rules unconstitutional.

“It was already known that mangroves were among the most important ecosystems in the world as carbon sinks. In our work, what we can highlight is the significant importance of Brazilian mangroves to this carbon stock and that their conservation, avoiding deforestation, can act to mitigate the effects of climate change. climate, as protectors of the coast,” said oceanographer Flavia Muchel.

“In this case, in particular, I would like to stress the importance of working to restore degraded mangrove forests to recreate this ecosystem in deforested areas. Restoring the environment by planting and growing seedlings leads to increased carbon. The researcher concludes that this role “in The final calculation of the “carbon stock is basic”.

All universities in Maranhão (UFMA, UEMA, UEMASul, UniCEUMA and IFMA) participated in the research, as well as out-of-state research institutions such as the National Institute for Space Research (INPE) and the Center for Research Monitoring and Disaster Warning. Natural (CEMADEN). are they:

According to the scientists, the next step is to complete the research conducted by student Adriano de Lima Santos (Masters student in Development and Environment / PRODEMA at UFMA), entitled “The potential of mangroves in the coastal region of Maranhão to mitigate climate change”, in which unprecedented data is generated on Insulation capacity and modifications in mangrove areas of Maranhão. Scheduled for publication in July 2022.
