8pgs, The global trend of urbanization coupled with an increasing awareness of the importance of food systems resilience, has led to an increasing interest in urban agriculture to sustainably feed the rapidly growing urban population and mitigate against food supply chain disruptions. While home and community gardens have been long studied, there has been relatively little empirical research focused specifically on commercial urban agriculture (CUA) operations. The purpose of this study was to characterize commercial urban farms, and to identify their primary barriers to business development and expansion, their perceptions of future opportunities, and their specific informational needs. Because CUA has received relatively less attention in previous empirical research, a qualitative approach was used for this needs assessment to collect rich, contextualized information to help differentiate the specific barriers, opportunities and needs of CUA operations as opposed to their rural counterparts. We conducted semi-structured interviews (n = 29) of CUA producers in Florida. These interviews revealed that CUA operations face many of the same barriers that are common to establishing and growing small farms, with additional barriers due to local government regulations and tensions associated with farming on land that is not traditionally used for agriculture. Despite these difficulties, CUA operators believe their urban location is a key benefit to their operation and they see a variety of opportunities for future business and market expansion.
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.
