}A review is made of the ecological interactions that occur between shade trees and the perennial crops: coffee (Coffee spp. L.), cacao (Theobroma cacao L.) and tea (Camellia sinensis L. Kuntze). These interactions are classified firstly as advantages or disadvantages, and secondly as: effects on crop management; effects on the hydrological cycle; effects on pathogens, insects and climatic conditions; and effects on soils. References are given for the 20 advantageous and 16 disadvantageous…

Deterioration of cocoa was rapid under the no-shade conditions partly because of the high loss of exchangeable bases and the greater stress caused by the higher yield, and therefore the economic life of an unshaded Amelonado cocoa farm in Ghana may not last for more than 10 years of intensive cropping.
