Here’s a comprehensive framework for measuring carbon sequestration in agarwood plantations:
1. Concept: Carbon Sequestration in Plantations
Carbon sequestration is the process by which trees absorb CO₂ from the atmosphere and store it as biomass in trunks, branches, leaves, and soil.
Agarwood (Aquilaria malaccensis) plantations can serve as carbon sinks, contributing to:
- Climate change mitigation
- ESG reporting and carbon credits
- Sustainable branding for luxury Oud products
2. Key Metrics for Carbon Sequestration
| Metric | Description | Measurement Method |
|---|---|---|
| Aboveground Biomass (AGB) | Carbon stored in tree trunks, branches, leaves | Tree diameter at breast height (DBH), height, species-specific allometric equations |
| Belowground Biomass (BGB) | Carbon stored in roots | Allometric equations or root-to-shoot ratio estimates |
| Soil Organic Carbon (SOC) | Carbon stored in soil | Soil sampling at different depths, lab analysis for carbon content |
| Total Carbon Stock | Combined aboveground, belowground, and soil carbon | Sum of AGB + BGB + SOC |
| Annual Carbon Sequestration Rate | CO₂ captured per year | Derived from periodic biomass measurements and growth rates |
| Carbon Credit Potential | Equivalent CO₂ offset | Total carbon stock × conversion factor to CO₂ equivalent |
3. Measurement Methods
A. Direct Field Measurement
- Measure DBH (Diameter at Breast Height) and tree height
- Apply species-specific allometric equations to estimate biomass
- Calculate carbon content (typically 50% of biomass is carbon)
B. Soil Sampling
- Collect soil samples at multiple depths (e.g., 0–30 cm, 30–60 cm)
- Analyze organic carbon content in the lab
C. Remote Sensing & GIS
- Use satellite imagery or drones to assess canopy cover and tree density
- Estimate carbon stocks across large plantations
D. Modeling & Digital Twin Integration
- Combine IoT sensor data, growth rates, and digital twin models to simulate carbon accumulation over time
- Update real-time carbon sequestration estimates for reporting and ESG purposes
4. Integration with Blockchain for Transparency
- Record carbon measurements and growth data in the plantation’s digital twin
- Store verified carbon data immutably on blockchain
- Link carbon sequestration records to NFT-backed products or ESG dashboards for transparency
- Enables carbon credit certification and sale to investors or buyers
5. Benefits of Measuring Carbon Sequestration
| Stakeholder | Benefit |
|---|---|
| Farmers / Plantation Owners | Quantify carbon sequestration for potential carbon credits and ESG recognition |
| Luxury Brands / Exporters | Market sustainability and climate-positive impact to consumers |
| Regulators & NGOs | Transparent verification of carbon offset and compliance with climate policies |
| Investors | ESG-aligned investment insights |
| Consumers | Verified environmental impact strengthens brand loyalty and trust |
