A study of urban agriculture in Kinshasa, Democratic Republic of Congo—a sector described as vital for food security and employment amid rapid urbanization, food insecurity, and unemployment, where farms face significant challenges including land pressure, restricted access to credit, and lack of institutional support. The study aimed to (i) examine the motivations of agri-entrepreneurs, (ii) assess their impact on farm viability, and (iii) identify the economic and non-economic factors influencing business sustainability, using a qualitative and quantitative survey combining 20 semi-structured interviews across three peripheral zones (via snowball sampling) with documentary analysis. Three categories of entrepreneurs were identified: civil servants farming as a supplementary activity, private-sector employees investing in farming, and traders farming to secure their survival. Non-pecuniary motivations such as social engagement and passion strengthened resilience, but land insecurity, a financing deficit, and lack of training were identified as the major obstacles farms face; observed adaptive strategies included diversification and informal partnerships. The study concludes by calling for integrated strategies to secure land tenure, facilitate access to credit, and professionalize the sector while integrating peri-urban agriculture into urban planning processes.

This review identifies challenges for strawberry cultivation in urban production systems, noting that new urban farmers often lack the specialist knowledge of commercial growers. Common bottlenecks include plant physiology, pathogen management, choice of propagation material, fertigation, pollination, and environmental requirements. This knowledge gap appears to result in the abandonment of strawberries as a crop of choice in urban systems.

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.

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 research identified and analyzed determinants of urban agricultural product commercialization, using the Mhuysqa indigenous community of Bosa, Bogotá, as a case study. Data were collected through documentary research, garden observations, surveys of 33 gardeners, and interviews with four experts. Results show that urban agriculture in the cabildo is multifunctional, but the surplus available for sale is low, at less than 30%. Key determinants for commercialization include establishing and fulfilling objectives, supply volume/quality/frequency, technical production capacities, product presentation, collection/transport costs, payment methods, and having fixed buyers.

A review of existing literature and a case study of three urban farms in Singapore were conducted to examine their community contributions. Content analysis of 27 interviews with employees and volunteers revealed that these farms empower participants, generate social capital, provide jobs, involve marginalized groups, and promote pro-environmental behaviors. However, the farms were limited by poor job prospects and lower-than-expected yield.

This study analyzed land markets and their influence on peri-urban agriculture and livelihood strategies in Tanzania. It found that widespread monetary land markets, including formal, informal, speculative, entrepreneurial, and land grabbing forms, are transforming peri-urban agriculture into non-farm activities. These informal changes are causing a “sendoff” of peri-urban agriculture, and if unmanaged, land markets are suggested to become a blight for indigenous people selling land.

While indoor farming systems like vertical farming enhance urban access to food, the cost of CEA remains high, though it is decreasing due to technological advances.

Benjamin Felix Richardson · · New Zealand (Auckland)

Auckland's urban sprawl threatens to significantly raise the price of fresh fruits and vegetables across the country, worsening chronic food security issues. Food production has become detached from the food security and food sovereignty of Aotearoa's people. The severity of this issue is driving calls for reform, and a conflict exists between humanity's agricultural subsistence and the destabilizing demands of financial extraction, where crucial productive hubs can be lost permanently.

This study inventoried and characterized food production systems in Rincon, Bonaire, combining literature review and online key-informant interviews with biophysical analysis and calculations of land and water requirements for several production scales, and applying a SWOT analysis to multiple production systems. It found that increasing year-round fruit and vegetable production in Rincon, and Bonaire more broadly, is challenging and may not be feasible without support, given limited and irregular water availability, an unsupportive business environment, and harsh conditions from pests, diseases, and weather; without sufficient support to expand water availability, local agricultural knowledge, and a suitable business environment, neither capital-intensive nor small-scale crop production is likely to improve the availability of healthy food or employment opportunities.
