Unravelling drivers of high variability of on-farm cocoa yields across environmental gradients in Ghana

Abstract CONTEXT Cocoa (Theobroma cacao L.) is one of the world's most important agricultural commodity crops with the largest share of global production concentrated in West Africa. Current on-farm yields in this region are low and are expected to decrease in response to climate change, through warming and shifts in rainfall. Interventions intended to improve yields and climate adaptation require an understanding of the main drivers of yields across farms. OBJECTIVE In this regard, we quantified the extent to which environmental (i.e., climate and soil) conditions drive cocoa yields and how t... Mehr ...
