Coastal Blue Carbon Sequestration
Research Guide
What is Coastal Blue Carbon Sequestration?
Coastal blue carbon sequestration refers to the process of carbon capture and long-term storage in coastal vegetated ecosystems including mangroves, salt marshes, and seagrasses.
These ecosystems sequester carbon at rates up to 50 times higher than terrestrial forests per unit area (Pendleton et al., 2012, 1668 citations). Habitat conversion releases stored carbon equivalent to 1% of annual global emissions. Restoration enhances sequestration while supporting biodiversity and coastal protection.
Why It Matters
Coastal blue carbon supports climate mitigation by storing 500 Tg C annually, offsetting emissions through credits and policy incentives (Pendleton et al., 2012; Wylie et al., 2016). Mangrove and seagrass restoration projects generate revenue via carbon markets, as shown in global case studies achieving successful verification (Wylie et al., 2016, 305 citations). Seaweed farming exports carbon to deep oceans, aiding adaptation in vulnerable coastal communities (Duarte et al., 2017, 612 citations). Integration into marine reserves enhances resilience against climate impacts (Roberts et al., 2017, 597 citations).
Key Research Challenges
Quantifying emissions from degradation
Conversion of mangroves and marshes releases stored carbon, but global estimates vary due to incomplete data on degradation rates (Pendleton et al., 2012). Soil carbon stocks differ by habitat, complicating accounting. Standardized measurement protocols remain underdeveloped.
Restoration scalability limits
Techniques like eelgrass transplanting succeed locally but face sediment and herbivory barriers at scale (Zhou et al., 2014). Management practices must balance carbon gains with biodiversity (Macreadie et al., 2017, 296 citations). Climate variability reduces predictability of outcomes (Lovelock and Reef, 2020).
Seaweed farming risks
Macroalgae cultivation sequesters carbon via export but risks nutrient pollution and ecosystem shifts (Campbell et al., 2019, 294 citations). Knowledge gaps hinder sustainable expansion in Europe. Balancing mitigation with biodiversity impacts requires prioritized research.
