This paper offers a less known biomass depletion and atmospheric carbon emissions due to habitat alteration in the Kahe Forest Reserve (KFR), Northern Tanzania, during a two-decade span (2003–2023). The paper measures biomass depletion, carbon emissions, carbon dioxide emissions, and the consequent economic effects due to losses in carbon trading. The study used the NAFORMA methodology alongside geospatial analysis to evaluate the ecological and economic impacts of land-use and land-cover alterations inside the reserve. The findings indicate a significant biomass reduction of roughly 23,019.6 tonnes, with corresponding carbon emissions totaling 10,819.2 tonnes. The study quantifies carbon dioxide emissions at 39,706.46 tonnes and assesses a carbon trade loss amounting to US$ 158,825.83. The data underscore the considerable environmental issues confronting KFR, intensified by a 141.4% surge in the human population in the adjacent districts from 1967 to 2022. This demographic pressure has resulted in unlawful agricultural encroachment, although existing protective restrictions, undermining the forest's ecological integrity and carbon sequestration potential. The results highlight the immediate necessity for action to prevent additional habitat deterioration and biodiversity decline. The study concludes with multiple policy recommendations, such as strengthened enforcement of forest protection measures, enhanced community engagement and education, promotion of sustainable agricultural practices beyond the reserve, restoration initiatives, and the incorporation of KFR into global carbon markets. These measures are essential for preserving the ecological integrity of the reserve and guaranteeing the sustainable stewardship of the region's natural resources.
