The Mekong Delta is sinking. Projections indicate that 90 per cent of this life-sustaining landform could disappear by 2100 due to human-driven factors such as groundwater pumping and sediment capture by dams, compounding the effects of sea-level rise.

Abatify Summary
Nature & Climate Perspective
**The rapid subsidence of the Mekong Delta represents a catastrophic failure of deltaic sediment cycles, threatening to flip a critical global carbon sink into a major source of methane and CO2 emissions. **
- Loss of 90% of the deltaic landform by 2100 would result in the permanent destruction of diverse mangrove and wetland biodiversity hotspots essential for coastal protection.
- The inundation of deltaic soils compromises Blue Carbon sequestration potential, as salt-water intrusion accelerates the decomposition of organic matter and disrupts carbon burial processes.
- Groundwater depletion and sediment capture by upstream dams prevent natural land-building, undermining the long-term environmental stability and adaptive capacity of the entire Indo-Pacific coastal region.
Market & Policy Outlook
**The collapse of the world’s great deltas poses a systemic threat to global food security and supply chain continuity, necessitating a shift toward Article 6. 2-driven adaptation financing.**
- Policy frameworks must evolve to integrate LULUCF accounting with sediment management, potentially utilizing Article 6.2 ITMOs to fund cross-border river basin management and delta restoration.
- Market pricing for carbon credits in coastal regions faces increased 'permanence' risk under ICVCM Core Carbon Principles (CCPs), as rising sea levels and subsidence threaten the longevity of nature-based sequestration projects.
- Corporates with agricultural dependencies in Southeast Asia face severe Scope 3 physical risks, requiring urgent investment in SBTi-aligned nature-positive strategies to mitigate the impact of localized food system collapse.
