This study analyzes protected cultivation and hydroponics in Brazil as technologies enabling full control of environmental variables and eliminating dependence on climate seasonality. These technologies demonstrate 80-95% reductions in water consumption, 300-500% increases in productivity compared to open fields, and complete elimination of agrochemical residues. However, the study also points out implementation challenges for these technologies, concluding they are fundamental for food security in contexts of accelerated urbanization, water scarcity, and global climate change.

A paper on vertical farming — a controlled-environment agriculture system — examines its potential integration with energy markets. It states that vertical farming's economic viability is constrained by high capital and operational costs, a substantial share of which is energy expenditure, and explores how vertical farms could participate in day-ahead, balancing, and flexibility energy markets by adjusting lighting and climate-control energy use in response to market signals, potentially reducing costs and generating additional revenue. It identifies gaps in understanding of plant responses to variable lighting as a critical barrier to implementation and illustrates these integration challenges through small-scale laboratory experiments.

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.

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.
