Abstract:

Carbon sequestration potential of coffee agroforestry system was studied in Mubende and Mityana
districts, Uganda between 2014 and 2015. Information on tree density, species density, species
richness, species composition and amount of above ground carbon stocks was collected through
square plots of lOmxlOm placed at alternative interval of 10m (How?). To collect information on
socio-economic variables and management types, the study used cross-sectional design. Results
indicate that, the average number of trees per hectare of each farm was 72 trees and the mean species
richness was 10 species and mean basal area was 10.3 m2/ha, total aboveground tree biomass and
diameter were positively correlated for all species and the total discounted NPV (US $ 1,3 18/ha) of
shade coffee agroforestry system from lha of land in Mubende/Mityana districts was profitable
under low discount rate. Conclusively, shade coffee agroforestry has potential to sequester
significant 1.0 to 18.0 Mg C ha’1 amount (What amount?) of carbon in the aboveground woody
biomass and if well managed, it can also provide substantial economic benefits to the farmer because
it is profitable especially when fruit and timber tree species are included. Therefore, shade coffee
farmers should be trained in best tree-coffee management practices for optimization of both
biodiversity and tree-crop productivity of the farming system.
