Global mangroves rebound after decades of loss | News | Eco-Business | Asia Pacific

Nature & Climate Perspective

Global mangrove expansion signifies a critical turning point for coastal blue carbon sinks and marine biodiversity stabilization despite regional vulnerabilities.

• Restores critical nursery habitats for coastal and marine fisheries, reversing long-standing declines in nearshore biodiversity.
• Accelerates carbon sequestration density via sediment-trapped organic matter within the Blue Carbon and LULUCF accounting spheres.
• Enhances natural storm surge buffering and coastline stabilization, though uneven geographic gains highlight ongoing vulnerability in unmonitored tropical zones.

Market & Policy Outlook

The transition to net-positive mangrove extent increases potential Blue Carbon supply, yet ICVCM Core Carbon Principles (CCPs) will strictly gatekeep crediting based on additionality and permanence.

• Provides sovereign nations with measurable blue carbon baselines to leverage in bilateral ITMO agreements and sovereign transfers under Article 6.2 and Article 6.4.
• Drives price premiums for high-integrity coastal wetland restoration credits while non-CCP-aligned projects face steep discounting over permanence and leakage concerns.
• Enables corporate buyers to source high-durability Nature-based Solutions (NbS) aligned with the Science Based Targets initiative (SBTi) Beyond Value Chain Mitigation (BVCM) guidelines.
