This study examined the implications of urbanization-triggered industrial development on food security in Kiambu County, Kenya, neighboring Nairobi. Through mixed qualitative and survey-based data collection and analysis from 400 respondents including farmers, agricultural workers, urban planners, and government officials, the study found an 85% increase in farmland conversion to industries over the last 20 years. This industrialization contributed to a decline in food production, as reported by 65% of respondents who left farming for industrial jobs. Land-use transformations have resulted in fewer farms involved in agriculture and the replacement of old food systems.

This research explored the economic viability of community gardens in Semarang City, Indonesia, using a qualitative approach with 24 participants. Findings indicate that most community gardens operate at a financial loss, showing weak economic viability. However, these gardens continue to function sustainably, driven not by profit but by government programs, social cohesion, and environmental concern.

Paule Moustier, Jacques Pagès · HAL (Le Centre pour la Communication Scientifique Directe) · Africa

This study examined peri-urban agriculture in Africa, identifying it as a significant income and food source for the urban poor, but subject to constraints, primarily land pressure. Analysis of the vegetable supply chain in Brazzaville showed rural and peri-urban areas are complementary, with different types of vegetables originating from each. Land constraints, transport, access to inputs, and technical assistance are crucial factors determining production location. Historical analysis invalidates hypotheses of linear decline or development through intensification for peri-urban agriculture.

At the Christchurch College of Food Technology in New Zealand, researchers compared five growing systems -- rooftop container, raised bed, peri-urban orchard, rural orchard (reference), and heated greenhouse -- for avocado (Persea americana) cv. 'Hass' under simulated Bavarian Plateau conditions, using a randomized complete block design with four replications over three years (2020-2022). The rural orchard yielded highest at 22.3 kg per tree, peri-urban raised beds achieved 18.7 kg per tree using 56% less land, and rooftop containers (200 L pots) produced only 6.8 kg per tree, confirming that container culture is viable but yield-limited; rooftop systems had the lowest weed pressure, peri-urban orchards supported the richest arthropod biodiversity, and ISSR molecular markers confirmed genetic uniformity among grafted plants across systems, ruling out somaclonal variation as a source of the yield differences.

Focused on "Merko Hidroponik," a Merck Family Foundation-funded hydroponic (NFT) lettuce enterprise in Banjarbaru City, Indonesia, adopted as urban farming to address declining agricultural land, this study (2025) used descriptive methods to calculate total costs, revenue, profit, and business feasibility (R/C ratio) for the period March 2023 to July 2024, during which 11 planting cycles were completed from seeding through nursery, growth management, harvest, and post-harvest processing. Total costs were Rp7,906,424, total revenue Rp9,920,000, and profit Rp2,013,576, yielding a feasibility ratio of 1.254, concluded to make the business "feasible" to run. However, the study also identifies that the enterprise currently faces problems of root rot disease, managerial inefficiency, and challenges maintaining production continuity.

A case study of Greenhouse X, an urban farming enterprise in Bandung, Indonesia, found that its hydroponic water spinach (kangkung) supply has not been able to optimally meet market demand, and that its supplier-farmer partners are often inconsistent in meeting supply targets. Using a qualitative case-study method analyzed descriptively, the study identified 19 production risk events. The highest-severity risks (Si=9) were plant death during growth and root rot; harvest delays and unmet product quantity were rated as extreme-impact risks (Si=8).

Against the backdrop of urban farming as a strategic response to land scarcity and food security challenges in metropolitan areas, this study examined the financial performance and internal marketing value of shallot (Allium cepa var. aggregatum) agribusiness grown hydroponically using Nutrient Film Technique (NFT) and Deep Flow Technique (DFT) systems across two planting cycles. As a case study at P4S Galih Jaya, Indonesia, the quantitative descriptive research combined direct observation, financial documentation review and structured stakeholder interviews, calculating standard agribusiness financial metrics — production output, net income, Benefit-Cost (B/C) ratio and Break-Even Point (BEP) — while internal marketing indicators (employee understanding, decision alignment and motivation) were assessed via pre- and post-cycle surveys. The DFT system in cycle 2 yielded the highest net income (IDR 2,036,725) and B/C ratio (3.6), while the NFT system in cycle 1 incurred a financial loss of IDR 10,155 with a B/C ratio of only 0.9, indicating it was unprofitable. Internal marketing indicators showed clear improvement between periods, and the study concludes that the choice of hydroponic system affects not only profitability but also internal stakeholder engagement.

A study of the rate and direction of spatial expansion of Robe Town, Ethiopia, into surrounding rural kebeles, and its effect on the tenure security of peri-urban landholders. It combined socioeconomic data from 202 sampled household heads with spatial data from Landsat images taken in 1987, 2002, and 2020. The town grew annually by 18.6% (1984–1994), 11.3% (1994–2007), and 9.3% (2007–2020), with its total area rising from 5.1 km² in 1984 to 80.2 km², a 40.9% overall increase. Over the 33-year period, built-up area expanded fastest southward, reaching 9.91 km from the town's mean center, and grew from 4.38 km² in 1987 to 27.9 km² in 2020; about 10.2 km² of farmland was converted to built-up land between 1987 and 2020. In peri-urban areas of Robe town, 48.9% of landowners lost around half of their farmland, leaving peri-urban landowners feeling insecure about their tenure due to fear of eviction and expropriation at minimal compensation.

A mixed-methods, cross-sectional descriptive study of urban agriculture in Gulele sub-city, Addis Ababa, Ethiopia, examining perceptions, opportunities, and challenges. It combined a survey of employees and farmers, in-depth interviews with farmers, key informants, and experts, and a focus group discussion with civil service employees. The study identified scarcity of urban farmland, scarcity of water for irrigating vegetables, and constraints on various agricultural inputs as core problems, alongside market accessibility issues for selling produce and limited transportation availability, even as vegetable consumption and demand among urban dwellers were rising and government policy treated urban agriculture as a current priority. It also found a negative social attitude among urban dwellers toward urban agriculture, who regard it as old-fashioned work and view urban farmers as backward and uneducated. The study concludes that the Addis Ababa City Administration's urban agriculture development sector needs to work with research institutions to address pest and insect problems and to improve vegetable yield per unit of land.

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.
