Conclusion
Agroforestry has the potential to provide both economic and environmental benefits. IPCC
has recognized agroforestry as having the highest C sequestration potential of any land
management system. The greater the land area that is occupied by trees, the greater the
impact on atmospheric C. Agroforestry systems play an effective role in global carbon
sequestration, involved in carbon capture and long-term storage of atmospheric carbon
dioxide. There is a need to promote short rotation and fast-growing trees for quicker capture
and storage of carbon di oxide.
