In-Depth Information
However, the effects of smallholder soil/agroforestry management decisions on carbon-
related agroecosystem processes are not well documented and need further study.
The continuing use of agroforestry practices that are biotically compatible with
farming systems depends not only on benefits to food security and the environment
but also on compatibility with farming practices already in place, positive policy
context, awareness among farmers of the management practices and potential ben-
efits, and constraints to seed supply, land, and labor.
Use of carbon credits to recapitalize soil fertility is developing very slowly in
eastern and southern Africa. Further research is needed, especially in the area of soil
carbon cycling and the effects on carbon cycling of different management decisions.
