Planting more trees in the landscape is a spreading strategy to provide multiple ecosystem services in human-dominated environments. Scientists Kuyah et al. recently found in sub-Saharan Africa that agroforestry practices increase provisioning services such as crop yield while maintaining the delivery of regulating and maintenance services such as soil fertility, erosion or water regulation. They reckoned that selecting appropriate agroforestry practices and a suitable management of tree canopies can minimize trade-offs resulting from competition and shading.
