Monitoring forest carbon in a Tanzanian woodland using interferometric SAR: a novel methodology for REDD+

Table 1 Carbon credit estimation based on forest biomass changes for the study area based on InSAR height changes

Period	Height change	AGB change	CO₂ emission	Payment value
Period	m	t ha⁻¹ year⁻¹	t ha⁻¹	US$ ha⁻¹
MRV 2011 - 2012	−0.041	−0.58	−1.34	−6.68
Reference level 2000 - 2011	−0.437	−0.56	−1.30	−6.48
MRV deviation from reference level		−0.02	−0.04	−0.20

The 2011–2012 change is derived from TanDEM-X data in both years, while the 2000–2011 change is from SRTM to TanDEM-X. Height change is recalculated to AGB change assuming 14.1 t/ha/m, − this is further recalculated to CO₂ emissions assuming 2.31 t CO₂/t AGB, and this is further recalculated to a payment value assuming a carbon price of 5 $/t CO₂
