A qualitative study conducted semi-structured interviews with 35 stakeholders — home farmers, commercial producers, policymakers and agritech developers — in the United Arab Emirates, examined against the National Food Security Strategy 2051. It found 70% of home farmers engage in urban agriculture to reduce import dependency, but are constrained by high water costs (cited by 70%) and limited technical training (55%). Commercial farms widely use hydroponics (88%) and vertical farming (62%), though energy-water trade-offs limit scalability. Stakeholders emphasized AI-driven tools for water-use optimization (75%) and blockchain for traceability (45%); the most desired digital-platform features were real-time soil and weather data (90%), centralized subsidy access (80%) and market linkages (65%), though fragmented data systems currently limit their effectiveness. Policy implementation gaps persist, with 60% of farmers unaware of subsidy programs and minimal integration across agricultural initiatives; the study recommends expanding solar-powered irrigation subsidies, improving training and extension services, and developing a unified digital platform connecting farmers, policymakers and agritech stakeholders.

A technical paper presenting a parallel agent-based framework for analyzing vegetable trade dynamics within a metropolitan area. It combines agent-based and discrete-event techniques to model interactions among farmers (who select crops based on market trends and environmental risk) and vendors and consumers (who adapt purchasing behavior to seasonality, prices and availability). To handle the computational demands of large-scale scenarios, it employs an optimistic approximate parallel execution strategy and a credit-based load-balancing mechanism to improve scalability. The framework is presented as enabling detailed analysis of urban food distribution systems relevant to smart cities and digital agriculture.

In India, cultivation methods for optimizing lettuce production on household balconies were compared: circulating hydroponics, static hydroponics, and substrate cultivation against soil cultivation as a control, evaluating growth, yield, and quality. Hydroponic systems significantly outperformed soil cultivation. Static hydroponics produced the highest biomass, with fresh and dry weights increasing by 10.53% and 55.29% over the control. Circulating hydroponics had slightly lower yield but increased vitamin C content by 6.57% and sensory quality by 41%, ranking second overall. Substrate cultivation showed moderate gains, with vitamin C up 5.14% and taste rating up 19.66% versus the control. Considering growth performance, space efficiency, ease of management, and cost, static and circulating hydroponics were identified as the most suitable systems for balcony-based lettuce cultivation.

This review outlines hydroponics — soilless cultivation that feeds plant roots directly with nutrient-supplemented water, often using inert media such as perlite or coco coir. It states hydroponic systems use about 90% less water than conventional agriculture and describes applications for home and commercial urban growing in areas with limited arable land, as well as potential future use in inhospitable environments such as Mars or the Moon. It also notes the method is resource-intensive, requiring specific investment and expertise, and is not suitable for all crop types.

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.
