12 pages., In sub-Saharan Africa (SSA), declining soil fertility is among the factors affecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socio-economic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM communication in SSA. The objectives were to identify the current focus of studies on SFM communication, the current definitions of communication which informed such studies, and the type of SFM practices being communicated in the SSA region. Using specific search terms, articles were collected from various databases and content analysed. The review revealed five main themes as the focus of current studies on SFM. The study also revealed two main interpretations of communication which in turn influence the use of either diffusion or participatory communication strategies for SFM communication. The review also showed a focus on integrated soil fertility management (ISFM) messages in the SSA area. The study concludes that while each of the two communication strategies has their individual strengths, farmers prefer participatory strategies. This is because participatory strategies foster interaction and greater understanding; thereby, increasing the likelihood of farmer adoption of SFM practices in SSA. The review concludes by calling for further research on the use of participatory communication to engage farmers about various SFM practices in SSA.
10 pages., via online journal., Peri-urban environments, where agriculture and urbanization interact, pose unique challenges for soil management. In Miami-Dade County, Florida USA, this interaction is especially important; a population of 2.7 million lives in an urban county with only 6% of the area zoned agriculture. Miami-Dade County is a major producer of tropical fruit and winter vegetables for the U.S., and is located within the Everglades ecosystem. 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). All stakeholders perceived pressures from urbanization as the main barrier to farmers' ability to continue to produce food, maintain their soil health, and contribute to national food security. The mental models of farmers reveal their ability to continue farming depends on their ability to construct and sustain a system—the soil food value chain. In this system, the farmer generates farm capital from a combination of high quality products, lower quality produce, and culls. This farm capital includes value-added products or soil amendments. However, experts did not perceive their responsibility to include maintaining a system, rather, only improving production. Experts' research and extension focused on improving product quality, increasing yield, decreasing cost of production, and minimizing the environmental impact of production. The mental models of farmers suggest research and extension related to building and maintaining the entire soil food value chain would increase the likelihood the farmers would better care for their soil and be profitable. This research contributes to the literature by recognizing the importance of examining the barriers to soil communication between stakeholders, as well as the importance to include examining soil within the larger food system.
