This study examined the relationships among technological optimism, biospheric values, attention to media content on urban farming risks and benefits, and norm-activation constructs in predicting the intention to consume urban farm produce. A cross-sectional survey in Singapore (N=1209) found that technological optimism and biospheric values influenced attention to media content. These variables, in turn, influenced personal norms and consumption intention through the norm-activation constructs.

Marek Hekrle, Jan Macháč, Lenka Dubová · Resources · Czechia

This study investigated how ecosystem services (ES) provided by the community garden 'Žížala na Terase' in Czechia are affected during crises related to the COVID-19 pandemic and increased food prices. Results indicated that the importance of social interaction and educational ES significantly decreased in the COVID-19 scenario. Conversely, the role of community gardens as places for recreation increased. In the food self-provisioning scenario, provisioning ES increased at the expense of recreational ES. Economic assessment further showed that cultural ES were the most monetarily valued, followed by provisioning ES.

This paper assesses the potential economic, social, and environmental contributions of urban agriculture (UA) based on five key features: area, purpose, crop value, mechanisation level, and market mechanism. A review of 15 past studies, including those from Adelaide, Australia, and the Kathmandu Valley, Nepal, revealed that most UA research focuses on social benefits and cost savings. Few studies investigate economic viability, employment potential, or greenhouse gas reduction opportunities, indicating a need for a systems approach and diverse real-world case studies.

This study quantified changes in CO2 emissions, energy use, and financial cost when ventilation upgrades and rooftop garden installations are done simultaneously, with the potential to enhance plant growth from exhausted CO2. Researchers measured indoor CO2 concentrations (maximum 2210 ppm, median 840 ppm, 33% of daytime above 1000 ppm) and estimated ventilation rates (4 L/s). Model calculations showed that while increasing ventilation to recommended levels (7 L/s) would increase CO2 emissions, energy, and cost by 1-4%, rooftop garden installation benefits could counterbalance this, leading to a net decrease of 23-46% in CO2 emissions, 12-13% in energy use, and 12-16% in cost.

A systematic review of urban agriculture (UA) case studies identified conditions enabling and constraining UA development across different country income groups. For high-income countries, a lack of farmers' knowledge and urban development are significant challenges to UA implementation. Common requirements for all income levels include motivation, labor, policy, social capital, and arable land.

Emelie Larsson, Katarina Giritli Nygren · Journal of Risk Research · Global

This study analyzed strategy documents and municipal website information to examine how municipalities frame urban gardening as a risk-reduction strategy, using critical discourse analysis. It identified two discourses: an eco(no)logical risk discourse addressing ecological risks within a capitalist market logic, and a social risk discourse focusing on gardening for work training. The findings reveal that top-down urban garden initiatives highlight contemporary inequalities in urban spaces.

In this study, a greenhouse was designed for optimal production in the coastal area near Algiers. Data showed two main options for optimal production of tomatoes and similar products: winter production in a heated greenhouse or summer production with air-conditioning and CO2 injection. Estimated production is fairly similar for both seasons, but summer production costs are 30% higher. While investment costs for the summer production scenario are higher, running costs are lower due to less additional water and energy needed in summer.

This paper quantitatively analyzed the spatial extent of the food provisioning area for consumers in Kampala, Uganda, using a foodshed lens and primary survey data from households and food vendors. The study found that 50% of food consumed in Kampala originates within a 120 km radius, with 10% coming from within the city itself. Urban agricultural activities are currently twice as important as international imports for the city's food supply. High-income urban dwellers exhibit a more local foodshed due to their broad participation in urban agriculture, whereas low-income newcomers depend significantly on retailers sourcing food from rural Uganda.

This paper analyzes the intersection of urban art and community gardens to explore whether commons can emerge from this collaboration. Through a comparative study of two community garden projects in Berlin and Dakar, the research examines the impact of funding structures, accessibility, artistic concepts, and design on commoning. Findings reveal that the two projects differ significantly in their development context and underlying structures, affecting their ability to function as commons. Furthermore, the paper argues that the dependency of artistic involvement on third-party funding contradicts the principles of commoning.

This comparative case study of three Community-Supported Agriculture (CSA) initiatives in Portugal analyzed how power shapes transformations to postcapitalist work relations. Results showed that while CSA creates non-alienated, non-monetized, and care-filled postcapitalist work relations, they insufficiently unmake unbalanced power relations established in capitalist work relations. The selected CSA initiatives could benefit from actively deconstructing internal hierarchies, decentralizing decision-making power from farm owners, and addressing oppressive power relations ossified in their local and cultural context when establishing postcapitalist work relations.

Combining 30 years of temperature and rainfall data from the Tanzania Meteorological Agency with a questionnaire survey of 386 urban-agriculture households across five wards of Kinondoni City (Bunju 118, Kunduchi 42, Mabwepande 102, Mzimuni 28, Wazo 96), plus focus group discussions, key informant interviews and direct observation, this study examined climate change's effects on urban crop production and farmers' adaptation strategies. More than 70% of surveyed smallholder farmers were aware of climate change indicators, consistent with the meteorological data, citing rising temperature (76%) and declining rainfall (73%); pests and diseases were ranked highest (88%) among significant climate-change effects. Land scarcity was also identified as a significant challenge for urban agriculture, and pesticide and fertilizer use was the most commonly cited adaptation strategy (65%).

A study on private subsidiary farms—a critical component of Russia's national agricultural sector—argues that developing horticulture is an inexpensive and stable strategy for improving household food security. According to estimates from the Union of Gardeners of Russia, 125 million Russians belong to households that obtain food from land they cultivate themselves, and Rosstat estimates that of Russia's 8.851 trillion rubles in total agricultural production (at actual prices) in 2022, households accounted for 2.071 trillion rubles, a quarter of the total. However, amid growing sanctions pressure on the agricultural sector, both the number of farms and production efficiency indicators for personal consumption and sale have declined significantly, hindered by regulatory obstacles including the inapplicability of the 'dacha amnesty' to most allotment gardens, serious cadastral errors, growing numbers of abandoned plots, and new legislative restrictions on keeping farm animals and birds on garden plots.
