Are traditional agroforestry systems nature-based carbon sinks? Empirical evidence from Tanzania

Traditional agroforestry systems (TAFS) in Tanzania—Alalili, Ngitili, and Faidherbia parkland—play a critical role in biodiversity conservation, rural livelihoods, and climate change mitigation. This study quantified their carbon sequestration potential using field data from 48 plots. Results showed significant variation in total carbon stocks, with Faidherbia parkland storing the most (151.91 Mg C ha⁻¹) due to large-diameter trees, while Ngitili stored the least (17.96 Mg C ha⁻¹) despite higher stem density. These findings highlight TAFS as valuable nature-based carbon sinks and support their integration into climate strategies such as REDD+ and carbon farming. Strengthening TAFS can yield co-benefits for carbon storage, ecosystem services, and sustainable development.
