Blue carbon, a key point to face climate change in the world, is doubly threatened by rising sea levels, as well as by human actions that destroy ecosystems, experts on the PreCOP25 framework revealed Thursday.
The researcher at the Tropical Agronomic Center for Research and Education (CATIE), Miguel Cifuentes, said during a talk that the relevance of blue carbon is that the mangrove absorbs twice the carbon accumulation that dry, wet, and very humid forests .
"Blue carbon is doubly threatened, humans destroy the mangrove and give it another use to the ground such as shrimp farming or salt extraction, and with this we lose 92% on average carbon. This added to the rise in sea level "said Cifuentes.
According to experts, blue carbon is captured by the world's coastal ocean ecosystems, mainly mangroves, marshes, seagrasses and macroalgae, which makes it a key aspect to face climate change.
PreCOP25, which takes place in Costa Rica and is the pre-Conference meeting of the Parties to the Framework Convention on Climate Change (COP25), seeks to raise awareness about the importance of the oceans that have absorbed more than 70 70% of the excess heat generated in the system.
"We have seen the sea as the victim of climate change, and from Costa Rica we want to make a call that the sea can be seen as a solution, such as this great site of hope to adapt and mitigate the effects of climate change," he said in an interview with Efe the Deputy Minister of Water and Seas, Haydeé Rodríguez.
Worldwide 700 million people live in coastal areas, while research indicates that the ocean absorbs 25% of carbon dioxide emissions, so we must work to restore health to this ecosystem.
The threat of climate change and excess heat translates into changes in ecosystems, migratory patterns, acidification of the oceans, change in sea level and that also has direct implications in communities.
"The ocean is the great regulator of the planet's climate, it has absorbed all this amount of heat from the planet and new measures can be taken such as marine spatial planning, such as the blue economy and governance models where all the actors involved to plan are seen in the future based on science of how we want these seas, "Rodríguez said.
In the negotiations and on the climate change agenda, the issue of the oceans has been "above", for this reason Costa Rica seeks to raise the "level of ambition" and the importance of boosting blue carbon within countries, The Costa Rican Deputy Minister said.
According to the authorities, one must work with innovation and provide solutions to manage responsibly and jointly with coastal communities, governments and organizations.
Among the challenges, it is worth highlighting the blue vision, developing financial mechanisms, promoting restoration projects, providing monitoring and control, as well as accounting for carbon emissions and sequestration.
