How the change works
- 01 / Public decision
Agronomic rights and assistance
- 02 / Physical change
Protection of natural regrowth
- 03 / Possible outcome
Managed fields with trees
Protecting and pruning natural regrowth allows farmers to keep trees in the fields without starting over each time from a plantation.
Research and local documents ↓What the evidence tells us
Research on the greening of the Sahel documents farmer-led practices in Niger and Burkina Faso. Tree management, rights and local knowledge are central to landscape change.
Putting the choices into practice

The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
Not every tree is suitable for every crop. Rain, soil, species and access to benefits affect results; regrowth does not make the Sahel immune to drought.
Other possible benefits
Wood resources and soil protection, to be reconciled with the needs of crops.
