Short summary
Cocoa agroecosystems are a major land use type in West Africa, reportedly associated with the problem of soil degradation. This study developed a composite soil degradation assessment index (CSDI) for determining the degradation status of cocoa soils under smallholder farming systems in southwestern Nigeria. The newly developed index can show early warning signs of soil degradation, which can help farmers and extension officers to implement rehabilitation practices on degraded cocoa soils.
