Mangroves and other coastal ecosystems, which include marshes and sea grasses, are classified as “blue carbon” ecosystems. Although they are now recognized for their potential to address the key climate and environmental challenges of our time, they still need more attention not only from policymakers, but also through scientific research. In recognition, the workshop organizers brought together over 50 government specialists and technicians from Mesoamerican countries to exchange and discuss options to support the inclusion of blue carbon in national climate change strategies, such as Nationally Determined Contributions (NDCs).
