• Over 90% of the 1.2 billion people living in extreme poverty depend on forests for livelihoods (World Bank, 2007).
Aim of the study• Determine contributions of forest products to Conservation Agriculture with special focus on African walnut.
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).
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).
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
African walnut is a climber which is planted under indigenous tree species within agricultural plantation e.g. cocoa
Climber of African walnut on crown of some indigenous trees on agricultural plantation (thereby conserving the trees)
Application of African walnutto 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.

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.
Issues for devt…• Lack of adequate storage facilities ▫ Consumed within 1-2 days after cook• Inadequate transportation ▫ deplorable rural road networks.
Food for thought• Let us recognize more and incorporate Indigenous Knowledge to CA.• “When a knowledgeable old person dies, a whole library disappears”.
