This study comprehensively reviewed the viability, benefits, and challenges of urban aquaponics systems in the United States. Through a systematic literature review and content analysis, significant environmental benefits were identified, while economically, long-term benefits potentially outweigh initial setup costs. Challenges such as technical complexities, financial barriers, and the need for specialized knowledge are also notable.

This paper focuses on the characteristics of vertical farms, using The Plant vertical farm in Chicago as an example to describe its design and performance, and analyze its advantages and design principles. The success of The Plant is attributed to saving raw materials and waste disposal costs through waste utilization, staggered electricity consumption, and insulated structures to maximize energy cost savings. However, while small-scale pilot projects of vertical farms have achieved some success, many constraints remain for scaling them up due to high construction and operation costs and high technical levels.

This review investigates Controlled Environment Agriculture (CEA) as a potential solution for food security, discussing its rationale, growth factors, and technologies. 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.

High customer turnover is a significant challenge in China's Community-Supported Agriculture (CSA) industry. This study utilized RFM models (Recency, Frequency, and Monetary) and algorithms to regularly rank and classify the consumption ability of CSA customers. This was achieved by analyzing their recent purchase time, number of times of consumption, and consumption data.

This review examined urban agriculture (UA) across technology, socio-economy, and policy, noting that supporting UA expansion in cities is challenging due to its poor economic profitability. The study highlighted UA's value beyond profitability, including social, health and well-being, disaster risk reduction, and environmental benefits. It also presented advancements in UA technologies and plant biotechnology as potential solutions for increasing the future profitability of commercial UA.

Vertical farming faces challenges such as high energy consumption, costs, and a lack of social acceptance. This study investigated public acceptance of micro-vertical farming using a deconstructed theory of planned behavior model. Results showed that the overall mean of public behavioral intentions to use vertical farming was 3.9, which is above neutral (3.00) but less than positive (4.00).

This research investigated the potential and limitations of plant factories (vertical farming) for urban food production. The STACKED method was developed to assess plant factory performance across multiple scales, from leaf to facility to city, analyzing resource requirements including energy, electricity, water, CO2, and land area use for fresh vegetable production. The study found that while plant factories feature extensive climate control, their necessity, effectiveness, and efficiency remain questionable, and their effects on the urban energy balance were also assessed.

A study of 149 respondents in Nairobi County examined urban and peri-urban agricultural practices, finding composting and open field farming popular but not the most profitable. More profitable practices like cattle rearing and mushroom farming were unpopular due to expensive inputs and specialized skills. The study indicates that popular practices are less profitable, highlighting a need for transformation towards controlled environment agriculture with policy support.

This review discusses the application of controlled environment agriculture (CEA) techniques to urban agriculture (UA), driven by increased market demand for local produce. While CEA offers opportunities for year-round production and resource-use efficiency, significant challenges remain due to the high costs of production in urban settings. The review emphasizes that for urban growers to benefit, studies evaluating CEA for commercial food production must consider economic viability.

A focus group interview with young urban farmers in Daegu, South Korea, explored job creation through urban farming. Participants perceived farming as physically demanding and unrewarding, despite seeing urban farming as a promising industry for job creation. They also noted a lack of national support policies and difficulties in participation. A contradiction was identified between the young farmers' desire to adopt labor-saving new technologies and the goal of creating jobs through traditional farming.

Pei Xin Koh · DR-NTU (Nanyang Technological University) · Singapore

This study aimed to verify the viability of vertical farming systems with LED supplementary light compared to conventional hydroponic farming systems, focusing on energy consumption, cost, plant growth quality, and yield. Experiments with Butterhead lettuce showed that LED lights contributed 90.12% of the total energy consumption in the vertical farming setup. The commercial viability and realistic cost levels of vertical farming have not been established, and a detailed cost-benefit and energy-benefit analysis is yet to be made.

Stephen R. Miller · · United States (Newark, New Jersey)

This article proposes a new approach to financing local food, viewing it as a finance problem similar to urban manufacturing, to scale up local food production. It explores the necessity of large-scale urban agriculture, focusing on vertical farms, and examines creative financing examples like AeroFarms in Newark, New Jersey. The paper suggests deploying existing and potential financing types, modeled on economic development agreements, to advance local food initiatives.

Against the backdrop of demographic projections that global population will reach 9.4 billion within the next 50 years, requiring an additional area of fertile land roughly the size of Brazil that does not exist on the planet, this study evaluated the economic viability of a Canadian vertical farm model as a sustainable urban-rural food production alternative. Using the NCIC method via a participant-observer approach, the study reported the model as economically viable and sustainable, as well as innovative in flattening production chains.

This study conducted 13 in-depth interviews with farmers to assess their perceptions of Freight Farms, a company growing leafy greens and basil in adapted shipping containers. Most farmers doubted the economic feasibility of Freight Farms, questioned its technologies, and noted the lack of organic certification.

This study noted that vertical farms face problems with economic viability and a lack of resident awareness. It derived types of vertical farms applicable to residential spaces and inferred assessment items for a questionnaire survey to develop u-services. Based on issues from the survey, u-services needed in vertical farm buildings were proposed, including u-notification of crop conditions, remote/automatic control u-services, harvest information u-service, recipe information u-service, indoor air quality monitoring u-service, indoor environment adjusting u-service, and farm environment control u-service.

Felipe de Jesús Cruz Celis, Héctor Montiel Campos · · Global

This study aimed to propose sustainability in urban agriculture through the use of hydroponic technology for agricultural production. Through documentary research and expert interviews, diagnostic criteria and sustainability indicators were determined, making hydroponics an option for producing food in reduced spaces. The results indicate that urban agriculture, due to its spatial scope, has limited possibilities for scaling up to the formal market, but can respond to family self-consumption needs and improve nutritional and higher quality foods.

Cheng Cun-ren · Journal of Agricultural Mechanization Research · China

This study introduces the status of machinery equipment for facility agriculture in China and compares it with foreign equipment. It analyzes problems in Chinese facility agriculture, finding that the current machinery equipment faces challenges in achieving high efficiency, quantity, and quality compared to international standards.

This study analyzed the transformation and reorganization processes of suburban agriculture and farmers in urbanizing areas, including "former farmer groups." It examined land conversion, changes in crop cultivation, farmer numbers, and agricultural employment. The research found that rental housing management is not economically viable, and that due to an abnormally high land price appreciation rate, the earlier rental housing management is undertaken, the greater the loss incurred, despite an observed increase in rental housing.
