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.

Six heavy metals (lead, cadmium, chromium, nickel, copper, zinc) were measured by atomic absorption spectrophotometry in spinach, amaranth and fenugreek collected from four peri-urban sites around Dhaka, Bangladesh, during January-March 2024, where more than 2,000 hectares of vegetable land are irrigated with untreated industrial and domestic wastewater via canal networks. Lead in amaranth from the industrial-effluent site reached 0.94 mg/kg fresh weight, more than three times the WHO/FAO permissible limit of 0.30 mg/kg, while cadmium, chromium and nickel stayed within permissible limits at all sites and zinc, though highest in absolute terms (8.6-14.7 mg/kg), also remained within safe limits; contamination was highest at the industrial-effluent site and lowest at the borewell-irrigated control site, indicating a localized food-safety risk for consumers of peri-urban leafy greens grown with wastewater irrigation.

In Semarang City, Indonesia, a survey of 86 farmers from four Women Farmer Groups (KWT) who received the government's Sustainable Food Yard (Pekarangan Pangan Lestari) program — using questionnaire interviews, descriptive analysis, and a literature review — assessed the program's social, economic, and environmental impacts. The social impact was rated "less" (score 31.10%), the economic impact "low" (28.88%), and the environmental impact "very low" (18.60%). The program strengthened social relations among farmers but was not effective in improving farming skills or public health; economically it had potential to contribute to household expenditure but had not optimized income growth or job creation; and its environmental impact remained limited, particularly in preserving biodiversity and reducing chemical use.

Interviews and a survey examined how residents of Bandung perceive the ecosystem services of homegarden-based urban agriculture. Residents themselves judged the gardens' contribution to overall food security to be only supplementary, even though they supply fresh produce. Their value was widely recognised elsewhere: biodiversity conservation, microclimate regulation, disaster risk reduction, social cohesion and mental well-being. Limited space, lack of knowledge and competing land uses emerged as the barriers, and the authors conclude that education and policy support are the levers for wider uptake.

Roopika Sivaraman, Haritha Thulaseedharan Nair, Sharmila Krishnan, Perumal Siddhuraju · Soil and Sediment Contamination An International Journal · India (Coimbatore)

This study analyzed biocompost and water samples from four agricultural nurseries in semi-urban Coimbatore, India, for microplastic contamination using density separation and ATR-FTIR. While physicochemical properties met Indian standards, microplastic fragments (85%) and fibers (15%) were found in two biocompost samples (BC-B and BC-C), identifying PMMA, PP, and EVA polymers. No microplastics were detected in samples BC-A and BC-D, but the findings suggest semi-urban agricultural gardening may contribute to microplastic accumulation in terrestrial environments, potentially harming soil and plant health.

Ji-Won Choe, Choong-Hyeon Oh · 환경정책 · South Korea

This study collected and analyzed 223 local government ordinances supporting urban agriculture in South Korea to identify its characteristics and propose institutional improvements. The analysis revealed regional imbalances in institutional support for urban agriculture, indicating a need to expand and revise direct support ordinances. Many direct support ordinances lacked explicit provisions regarding administration, expenses, technology, education, equipment, and locations, requiring amendment. It was also noted that the definition of urban agriculture tended to be narrower than in the "Act on the Promotion and Support of Urban Agriculture," and inconsistencies existed between the titles, purposes, and definitions of related ordinances.
