This paper presents a conceptualization of radical food democracy (RFD), linking diverse economies with diverse citizenship. Diverse economies scholarship, while valuable for theorizing alternative food networks (AFNs), has been criticized for essentializing the autonomy of alternative economic practices, risking the confusion of emancipatory social change with market-embedded products and the displacement of negative impacts. The paper argues that realizing RFD requires both experimenting with new economic practices that create food economies alternative to capital accumulation and cultivating new political subjects capable of universalizing these struggles.

This exploratory cross-sectional survey in seven rapidly growing neighborhoods in Wa, Ghana, administered 285 questionnaires to residents to understand motivations, challenges, and constraints of home gardening. Results showed 56% of respondents had gardens, primarily motivated by beautification (56.1%) and food production (52.3%). Limited space (49%) and busy schedules (34%) were identified as main barriers. The study found that while garden ownership aligned with the autonomy need, the relationship need, which correlates with environmental motivations, was notably low among residents. This indicates a limited effect of environmental awareness on home gardening motivation in the surveyed population.
