Shade management in coffee and cacao plantations

Background

Shade trees reduce the stress of coffee (Coffea spp.) and cacao (Theobroma cacao) by ameliorating adverse climatic conditions and nutritional imbalances and increase the biodiversity of coffee farms, but they may also compete for growth resources. This review summarizes the literature on ecological aspects of shade-grown coffee and cacao and on management of shade trees, but does not address economic and social aspects of shade-grown coffee and cacao.

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.
