Fewer pests and more ecosystem service‐providing arthropods in shady African cocoa farms: Insights from a data integration study

open access: yesJournal of Applied Ecology, Volume 61, Issue 2, Page 304-315, February 2024.
To achieve lower pest burdens and higher abundances of potential pollinators and natural enemies, African cocoa farms should maintain a dense canopy of shade trees. The current shift towards high‐intensity cocoa farming in Africa could result in long‐term losses due to pest infestations and loss of arthropod‐mediated ecosystem services.
