Challenges and Opportunities
1. FMNR – Widespread with diverse range of trees with multiple products and uses
2. Faidherbia – highly valued but distribution is not uniform and densities are low:
- Natural regeneration in natural range
- Plant air pruned seedlings outside its range
- Direct sow with pre treated seed
3. Other Planted Systems: Tephrosia, P peas, Gliricidia etc
4. Actions / Strategies / Incentives for scaling up
FMNR in Southern Africa
- Most widespread and successful AF system in Southern Africa & perhaps other regions of Africa
- Farmer driven practice – easy, low cost, multiple uses and products, restores natural diversity / builds resilience to environment & livelihoods
- Despite these facts, few organizations or donors know of or support this practice
- Needs high attention, research, exposure and publicity to attract support of Govts, Donors, NGOs and Private Sector to realize its potential
