  abstract = {{L}osses of carbon ({C}) stocks in terrestrial ecosystems and increasing concentrations of greenhouse gases in the atmosphere are challenges that scientists and policy makers have been facing in the recent past. {I}ntensified agricultural practices lead to a reduction in ecosystem carbon stocks, mainly due to removal of aboveground biomass as harvest and loss of carbon as {CO}2 through burning and/or decomposition. {E}vidence is emerging that agroforestry systems are promising management practices to increase aboveground and soil {C} stocks and reduce soil degradation, as well as to mitigate greenhouse gas emissions. {I}n the humid tropics, the potential of agroforestry (tree-based) systems to sequester {C} in vegetation can be over 70 {M}g {C} ha(-1), and up to 25 {M}g ha(-1) in the top 20 cm of soil. {I}n degraded soils of the sub-humid tropics, improved fallow agroforestry practices have been found to increase top soil {C} stocks up to 1.6 {M}g {C} ha(-1) y(-1) above continuous maize cropping. {S}oil {C} accretion is linked to the structural development of the soil, in particular to increasing {C} in water stable aggregates ({WSA}). {A} review of agroforestry practices in the humid tropics showed that these systems were able to mitigate {N}2{O} and {CO}2 emissions from soils and increase the {CH}4 {S}ink strength compared to cropping systems. {T}he increase in {N}2{O} and {CO}2 emissions after addition of legume residues in improved fallow systems in the sub-humid tropics indicates the importance of using lower quality organic inputs and increasing nutrient use efficiency to derive more direct and indirect benefits from the system. {I}n summary, these examples provide evidence of several pathways by which agroforestry systems can increase {C} sequestration and reduce greenhouse gas emissions.},
