The range of polymorphism of about 194 cocoa accessions collected in farms in Southern Cameroon during field surveys and 71 Trinitario and Upper Amazon clones available in genebanks on-station was assessed using 13 SSR markers. The gene diversity, genetic differentiation and genetic similarities ...

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...

Since 2000, children working in the cocoa sector of Côte d'Ivoire have found themselves in the media spotlight. This situation has assumed particular importance because approximately 40% of the world's cocoa production occurs in Côte d'Ivoire. Concerned parties have since taken great interest in ...

Understanding the vulnerability of forest and forest related sectors to climate change, mainstreaming the use of forest into adaptation strategies are some of the challenges faced by forestry research, developers and stakeholders. Despite the multiple efforts to mitigate climate change, it is wel...

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...

Cash crops are developing in the once forested areas of Indonesia in parallel with market and economic improvements. Perennial crops such as coffee, cocoa, and rubber were first planted in estates by private or public companies. Local people then integrated these crops into their farming systems,...

The paper analyses how macro-economic and agricultural policies, market fluctuations and demographic changes affected forests in the Humid Forest Zone of Cameroon in four periods between 1967 and 1997. For each period it examines how these variables influenced cocoa, coffee, food, and agro-indust...

The present study evaluated profitability of some models of cocoa farms and analyzed the relationship between cocoa yield, income and carbon stored in traditional cocoa agroforests to discuss implications of cocoa intensification on carbon emissions in Cameroun. Surveys on establishment, manageme...
