Relatively little information is known about research and extension within peri-urban environments concerning soil health and management. Ethnopedological work has contributed to ethno-scientific knowledge by bridging the communication gap between scientists and locals concerning soil taxonomies, soil health, and soil fertility management. This study explores mental models of farmers and experts, examining the communication gap concerning soil health and food security. Semi-structured interviews were used to collect data from farmers (n = 19) and experts (n = 13).
