Imports of pesticides have long been subsidised for use in the cocoa agroforests of the humid forest zone of southern Cameroon. With the liberalisation of the cocoa and pesticides sectors and the devaluation of the local currency (CFA franc), farmers are facing fluctuations in the price paid for ...

Sonwa, D.J.Coulibaly, O.Adesina, A.A.Weise, S.F.Tchatat, M.[Integrated pest Management in cocoa agroforest in Southern Cameroon: constraints and overview]Integrated pest Management in cocoa agroforest in Southern Cameroon: constraints and overview

In the humid forest zone of Southern Cameroon, farmers generally associate cocoa with native and exotic trees in complex agroforestry systems. Despite the socio-economic and ecological importance of these systems, few studies have investigated their plant composition. We investigated tree composi...


Sonwa, D.J.Nkongmeneck, B.A.Weise, S.F.Tchatat, M.Adesina, A.A.Janssens, M.J.J.[Diversity of plants in cocoa agroforests in the humid forest zone of Southern Cameroon]Diversity of plants in cocoa agroforests in the humid forest zone of Southern Cameroon

Dacryodes edulis, or safou, is a fruit tree native to Central Africa and the Gulf of Guinea region. It is usually present in agroforestry systems in the region, particularly in homegardens and cocoa and coffee agroforests. It plays an important role in household consumption and the surplus is sol...

Forest cover has deteriorated less in Central Africa than in West Africa. The cocoa cultivation practised in West Africa, after felling of the forest, has contributed to the destruction of that cover. Unlike West Africa, cocoa cultivation in Southern Cameroon (Centaral Africa) is done by smallhol...


Sonwa, D.J.Weise, S.F.Ndoye, O.Janssens, M.J.J.[Initiatives endogenes d'intensification et de diversification a l'interieur des agroforets-cacao au Sud-Cameroun: lecons pour une foresterie participative dans les systemes a base de cultures perennes en Afrique centrale et de l'Ouest]Initiatives endogenes d'intensification et de diversification a l'interieur des agroforets-cacao au Sud-Cameroun: lecons pour une foresterie participative dans les systemes a base de cultures perennes en Afrique centrale et de l'Ouest

Cocoa-producing countries of West and Central Africa experienced a serious economic crisis in the early 1980s, when the cocoa sector was liberalized and the macroeconomic policies of the sector changed. These institutional changes created new difficulties and challenges for sustainable cocoa farm...


Sonwa, D.J.Weise, S.F.Adesina, A.A.Nkongmeneck, B.A.Tchatat, M.Ndoye, O.[Production constraints on cocoa agroforetry systems in West and Central Africa: the need for integrated pest management and multi-institutional approaches]Production constraints on cocoa agroforetry systems in West and Central Africa: the need for integrated pest management and multi-institutional approaches

Over 70 years of familiarity with cocoa agroforests enables farmers of southern Cameroon to obtain food, medicinal plants and income from the ecosystem. Since 1994, social forestry activities in Cameroon have focused primarily on the idea of community forests. This approach is likely to encounter...


Sonwa, D.J.Weise, S.F.Tchatat, M.Nkongmeneck, B.A.Ndoye, O.Gockowski, J.[The role of cocoa agroforestry in rural and community forestry in southern Cameroon]The role of cocoa agroforestry in rural and community forestry in southern Cameroon

The aim of this paper is to determine the characteristics and preferences of cocoa farmers in the humid forest zone of Cameroon who are actively diversifying their cocoa agroforests by planting Dacryodes edulis. A survey conducted amongst 300 farmers revealed that about 80 percent of them grow Da...
