Central American Mangrove Blue Carbon: Distribution, Dynamics and Future Directions

Area of Science:

• Ecology
• Climate Science
• Blue Carbon Ecosystems

Background:

• Mangroves are critical Blue Carbon ecosystems in tropical and subtropical regions.
• They sequester atmospheric carbon dioxide more effectively per unit area than terrestrial forests.
• Estimates of carbon stocks in Central American mangroves vary due to geomorphology, local conditions, and species composition differences between Pacific and Atlantic coasts.

Purpose of the Study:

• To review current knowledge on mangrove distribution, carbon sequestration, dynamics, and resilience in Central America.
• To identify key research questions regarding mangrove responses to future climate change.
• To inform policy and management for Blue Carbon ecosystems as natural climate solutions.

Main Methods:

• Literature review and synthesis of existing research on Central American mangroves.
• Assessment of carbon stock variability and influencing factors.
• Analysis of climate change predictions for the region and their potential impact on mangroves.

Main Results:

• Significant variation exists in Central American mangrove carbon stock estimates.
• Pacific and Atlantic coastlines exhibit distinct geomorphology, environmental conditions, and species composition.
• Central America faces predicted climate changes including rising temperatures, increased cyclone frequency, and drought.

Conclusions:

• Understanding mangrove resilience and vulnerability is crucial for climate change adaptation and disaster risk reduction.
• Blue Carbon ecosystems offer potential for natural climate solutions and ecosystem-based adaptation.
• Further research is needed to address knowledge gaps concerning mangrove responses to environmental change.
