A workshop report (HortTechnology, 2020) documents a July 23, 2019 session held in Las Vegas by the Consumer Horticulture and Master Gardener Professional Interest Group at the American Society for Horticultural Science annual conference, which discussed terminology resonant with millennials (e.g., plant parent, plant enthusiast, urban agriculture) and featured presentations on social media outreach on Instagram, retail point-of-sale promotions, and botanical garden programming aimed at younger audiences. The group concluded that more consumer horticulture professionals should engage in tailored social media outreach and recommended further research into consumer behavior and retail marketing preferences among millennials.

Michael Carolan · Journal of the American Planning Association · United States

This 2019 study, based on 82 interviews in Denver, New York, and San Francisco, investigated how traditional and digital urban agriculture converge and diverge regarding land use and gentrification. It found that both digital and traditional urban farming systems are linked to gentrification and inequitable land use patterns. Digital urban farming systems also operate in a regulatory gray area, with their "digital" aspects used to gain more zoning permission than traditional urban agriculture.

This research investigates the significance of soil in distinguishing urban agriculture forms in San Diego County and examines how soil-based and soilless growing methods relate to justice. The results illustrate that while the way food is grown is important for urban agriculture organizations' identity and practices, it is only one of many factors influencing justice, such as socio-spatial context. Justice is an ongoing process that evolves as urban agriculture commodities travel through their circuits and interact with placed networks filled with intentions, actions, discourses, objects, actors, and forces.

Against a backdrop of a growing number of organizations in the US Great Lakes region growing local food year-round despite cold-climate conditions, this chapter uses diffusion of innovation theory to explain the adoption of commercial aquaponics (combined indoor fish and produce production). It notes that research has shown significant challenges to maintaining profitable commercial aquaponics ventures in temperate climates, even as the technology's popularity in urban agriculture appears to be increasing, and argues that perceptions of relative advantage, compatibility, complexity, trialability, and observability may explain its adoption despite these financial challenges.
