This paper explores the arguments and internal disagreements among experts popularizing vertical farming (VF), an emerging urban food production system. While VF is promoted for its space efficiency and independence from weather, it faces debates regarding its unsustainability and high energy costs for producing a limited range of perishable foods. Findings indicate that disagreements among vanguards reveal that VF is seen as one of many solutions, not the sole answer.

A survey study was conducted in Ghazel Dareh village, Markazi province, Iran, to design a Community Supported Agriculture (CSA) model for increasing food security. Questionnaires were administered to 110 active farmers, with 84 responses collected. The results indicated that economic, socio-institutional, policy-making, educational, and infrastructural factors significantly influenced CSA development. Infrastructural factors had the largest effect (impact factor 0.88), while socio-institutional factors had the smallest (impact factor 0.54). All impact factors were positive, suggesting that improving these factors could enhance CSA development in the study area.

This systematic review analyzed 66 reviews on the economic impact of nature-based solutions (NbS). Most reviews showed positive outcomes for income and employment, but those with critical appraisal of underlying studies reported more mixed outcomes. These results were influenced by factors such as the balance between short-term and long-term gains, market conditions, regional effects, reliance on subsidies, and discrepancies between expected and actual economic benefits. NbS delivered equal or better economic outcomes compared to alternatives and provided broader benefits like food security and flood protection, but improved monitoring of economic, social, and ecological outcomes and the development of comprehensive accounting systems are needed.

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.

This research extended the land sharing and sparing framework to urban land use, quantifying the impact of urban services, food production, and ecosystem services. The results showed that land-sparing scenarios had a 23.6% lower overall value loss than sharing scenarios on average. However, while land-sparing mitigates losses in food production and ecosystem services, it increases the cost of urban services, creating a trade-off that challenges achieving an optimal win-win situation.
