Satellite-Based Monitoring of Carbon Sequestration in African Mangrove Forests
Abstract
Comprehensive assessment of carbon storage in 12 African mangrove ecosystems using Sentinel-2 and Landsat 8 data, revealing sequestration rates of 2.4-3.8 Mg C ha⁻¹ yr⁻¹ across study sites.

}Mangrove forests play a crucial role in climate change mitigation through carbon sequestration. This study provides the first comprehensive assessment of carbon storage across 12 major African mangrove ecosystems from Senegal to Mozambique.
Data Sources
• Sentinel-2 MSI (10m resolution) for vegetation indices
• Landsat 8 OLI for historical analysis (2013-2023)
• GEDI LiDAR for canopy height validation
• Field measurements from 450 plots across study sites
Key Findings
1. Total carbon storage in studied mangroves: 840 ± 120 Tg C
2. Average sequestration rate: 2.4-3.8 Mg C ha⁻¹ yr⁻¹
3. Rufiji Delta (Tanzania) showed highest density: 1,023 ± 156 Mg C ha⁻¹
4. Total economic value of carbon storage: USD 12.6 billion (at $50/ton CO₂)
