2. • Over 90% of the 1.2
billion people living in
extreme poverty depend
on forests for livelihoods
(World Bank, 2007).
5. Aim of the study
• Determine contributions of forest
products to Conservation Agriculture
with special focus on African walnut.
6. African walnut
Tetracarpidium conophorum
(Müll. Arg.) Hutch. & Dalziel
• Family Euphorbiaceae;
• Perennial climber;
• Found in moist forest zones
of sub-Sahara Africa;
• Cultivated principally for the
nuts (cooked and consumed
as snacks).
7. Some benefits of African walnut
• Nuts
▫ Proved to cure male fertility problem
• Oil from nuts
▫ Used in formulation of wood varnish, vulcanized
oil for rubber and leather substitute.
• Leaves
▫ used for the treatment of dysentery (Ajaiyeoba
and Fadare, 2006).
12. Production of African walnut
• Nut planted under indigenous trees
deliberately spared on agricultural lands
and plantations
• Starts fruiting 2 years
• Fruits July – Sept
• Processing is at household level
13. African walnut is a climber which is planted
under indigenous tree species within
agricultural plantation e.g. cocoa
14. Climber of African walnut on crown of some
indigenous trees on agricultural plantation
(thereby conserving the trees)
16. Matured fruits allow to drop

22. Application of African walnut
to Conservation Agriculture
• Conserve indigenous tree species.
▫ Prevent felling
• Decay fruit mesocarp improves soil fertility.
• High litter fall that improve soil fertility.
▫ enhance function of soil microbs.
23. Mature fruits and climber of
walnut
Climber with many Decaying Mature fruits

25. Issues for development
• Producers: Small scale farmers at the local
level
• Industrial utilisation: Not fully developed.
▫ …hampering full scale production and
exploration of inherent potentials.
26. Issues for devt…
• Lack of adequate storage facilities
▫ Consumed within 1-2 days after cook
• Inadequate transportation
▫ deplorable rural road networks.
27. Food for thought
• Let us recognize more and incorporate
Indigenous Knowledge to CA.
• “When a knowledgeable old person dies, a
whole library disappears”.
