Carbon benefits, aggregated over all sites
Substantial variability between sites indicates potential
to increase carbon benefits, by improved management

• Variability depends partly on biophysical, climatic, and ecological factors
• Also on local management decisions, and socioeconomic constraints
• Optimal management for balancing food security and climate change
mitigation and adaptation must be responsive to local conditions.

With the support of
1. Mitigation in the agriculture sector and restoration of deforested and
degraded land is an essential part of the solution to climate change.
2. SLM interventions could restore extremely degraded and almost
uninhabitable ecosystems in SSA
3. Land rehabilitation and SLM already provides unintended carbon benefits in
these areas, while building productive capacity, ecosystem services,
resilience and adaptation.
4. SLM and mitigation co-benefits are not mutually exclusive – SLM creats a
vehicle for investment in land and ecosystem restoration
5. Climate change mitigation co-benefits could potentially support
sustainability and scalability via access to future climate finance
