This study designed and applied a cost-benefit analysis based on the Social Return on Investment (SROI) to five Community-Supported Agriculture (CSA) initiatives, addressing the lack of objective sustainability indicators. CSAs are local food supply chains characterized by member volunteer commitment, reduction of synthetic inputs in food production, and shortening of the supply chain. Findings revealed that the analyzed CSA case studies demonstrated a limited but positive socio-environmental performance compared to conventional food supply chains, thereby showing they can create real value in terms of social gains and mitigation of environmental impacts.

This study compared bioactive compounds in pomegranate genotypes from a continental region (Sremski Karlovci, Serbia) and a Mediterranean urban region (Bar, Montenegro). Analysis of phenolics, tannins, flavonoids, proanthocyanidins, pigments, vitamin C, acidity, pH, and sugars, along with DPPH and ABTS antioxidant tests, revealed that pomegranates grown in the continental area had significantly higher amounts of biochemically active compounds than those from the Mediterranean urban region. This suggests adaptation to continental conditions, with continental samples showing greater antioxidant potential and proanthocyanidins content.

This study in Cameroon explored the association between farming households' resilience and food/nutrition insecurity during COVID-19 lockdowns. Focus group discussions identified shocks and response strategies, followed by an in-depth study of 249 farming households. Econometric modeling revealed that COVID-19 shocks adversely affected food and nutrition security and reduced resilience capacity. However, existing adaptive capacity and access to basic services significantly contributed to resilience, with female-headed and semi-urban households showing greater resilience.

This chapter explored human-soil relations in urban home and community gardens through ethnographic fieldwork. While biodiverse soil offers direct health benefits, the presence of contaminated, toxic soils, prevalent in lower socio-economic neighborhoods, was shown to expose inequities in access to safe gardening sites and hinder the realization of potential therapeutic benefits. It argues that the therapeutic benefits of gardens are best realized when humans cultivate attentive relationships with myriad multispecies companions.

This article explores the "operational space" of urban community gardening (CG) from the viewpoint of city officials in Tampere, Finland. Two rounds of interviews with eight officials and discourse analysis were used, and the operational space, shaped by administrative policies and practices, was found to be rather rigid and narrow. Five main discourses aimed to enable urban gardening but were restricted to strategic, limited, and instrumental levels, as political-strategic aims contradicted administrative practices, and cautiousness and unclarity in the administrative-political culture led to institutional ambiguity.

This case study investigated non-chemical weed management strategies in a small-scale vegetable garden in Armidale, Australia, through observation and an in-depth, unstructured interview with the garden's convener. Growers primarily used mechanical and cultural methods, including mulching, hand weeding, tillage, and grazing, to manage weed infestation. While mulching with wood chips and hand weeding were considered more effective in minimizing weed competition during critical crop development periods, they could not reach a satisfactory level. Further improvements by integrating several approaches simultaneously are needed for more effective and economical weed control.

The current agri-food system is undergoing an unsustainable transition, with Urban Food Planning emerging as a holistic approach for sustainable transition. This paper explains and translates the "City-Region Food System (CRFS) Toolkit," developed in partnership with FAO, RUAF, and participating cities. It examines the toolkit's roadmap and approach for building more sustainable and resilient urban food systems through two case studies in West Africa. The research concluded that the CRFS Toolkit defines limited tools for building sustainable urban food systems and excludes the relationship with spatial disciplines.
