One of the contemporary challenges facing urban areas is the necessity to identify novel approaches to resident involvement in solution creation, with a particular focus on ensuring the best possible nutrition. By investigating the process of co-participation of city dwellers in a unique education project, this paper aims to gain a deeper understanding of the health-related motivations that underpin the decision of early adopters of the implemented technological innovations to join the social experiment. The qualitative study employed purposive sampling and in-depth interviews conducted in two waves, the first between October and November 2022 and the second between September 2023 and January 2024. The study comprised 42 participants drawn from two communities of residents in Łódź and Warsaw, Poland. Transcriptions of the interviews were carried out using semantic field analysis, employing a quantitative approach that counts the frequency of keyword occurrences. Three categories of semantic fields were identified: associations, oppositions, and actions toward the subject, including positive, neutral, and negative temperatures. The findings demonstrate that the health concerns of residents are a pivotal factor in their decision to participate in urban food self-production initiatives, given their limited access to nutritious and healthy vegetables. This is related to several factors, including restrictions related to urbanization and the displacement of local suppliers, lifestyle, and the fast pace of urban life. The dissemination of innovative solutions for growing food in urban environments could, therefore, facilitate awareness-raising and motivation to alter the dietary habits of inhabitants.

“…Previous research has shown that hydroponic crops grow 30-50% faster than conventional ones [32]. As an example, the open agriculture yield for a tomato crop is on average 5-12 tons per acre, while for hydroponic cultivation yield, it can reach 180-200 tons per acre [33,34]. Additionally, this type of cultivation is not labor-intensive, as production is more automated and industrialized thanks to the use of specialized equipment [35].…”

Among other agricultural systems that can contribute to sustainable food production, hydroponic systems are constantly gaining attention in terms of their economic viability and sustainability, while their ability to produce nutritious food has become more apparent in recent decades. The purpose of the study is to shed light on the potential of hydroponics to conduce sustainable food production systems, by focusing on the economic evaluation of a hydroponic greenhouse farm located in Western Greece. Particularly, the study aims at presenting an investment plan for a greenhouse farm of a total acreage of 0.2 hectares, where fresh tomato will be produced via hydroponic methods. The appraisal of the economic viability of the investment plan covers a 5-year period, while the Net Present Value (NPV) and the Internal Rate of Return (IRR) are used as criteria of feasibility and performance assessment. The study uses detailed technical and economic data—related to all costs and benefits deriving from the annual operation of the greenhouse farm—to assess three different economic feasibility scenarios based on the range of input, energy and product prices, taking into account the high volatility governing agricultural markets. The results show that economic viability is achieved during the 5-year assessment period in most scenarios, which is mainly due to the efficiency of the hydroponic systems. Investment performance indicators are adverse only for an “extreme” scenario with increased installation and production costs that are not counterbalanced by higher product prices or by financial support from the State. Despite the promising perspectives of hydroponics in Greece, its use is not yet widespread within the country. Further research should explore ways to increase adoption of such production methods, considering that immediate action is needed worldwide to improve the resilience of the food industry and promote environmentally friendly food production systems.

<abstract> <p>By 2050, the global population is anticipated to reach 10 billion, marking a significant 34% increase and raising concerns regarding food availability. Challenges such as the recent pandemic, which led to workforce and input shortages in agriculture, have made it difficult for many countries to maintain adequate food self-sufficiency (SSL). It is crucial to explore various farming methods to ensure that food remains available and affordable, especially in urban areas where over 55% of the population resides. Traditional agriculture faces issues like poor soil and excessive fertilizer use, which harm the environment. These factors threaten sustainable agriculture and food security, particularly in urban environments. Adopting sustainable soilless technology can enhance urban agriculture by providing a controlled environment for producing healthy food and addressing these challenges post-pandemic. This review, utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, a widely recognized and rigorous method for conducting systematic reviews, focused on urban agriculture, specifically soilless technologies, as emerging trends in crop cultivation. It examined conventional and cutting-edge urban production systems aimed at promoting sustainable agriculture and food security. The review examined soilless farming techniques such as aeroponics, hydroponics, and aquaponics, highlighting their environmental impact, resource efficiency, and water usage. It carefully considered the advantages and disadvantages of these technologies compared to conventional soil-based farming. Furthermore, the review showcased the successful cultivation of various fresh vegetables and fruits using soilless technologies, each with advantages supporting urban agriculture and overall food security. The findings suggest that these innovative strategies hold promise in fostering sustainable urban agriculture and ensuring food security during a pandemic. These results lay the groundwork for establishing a framework to assess the sustainability of urban agricultural strategies and their practical application in real-world scenarios.</p> </abstract>
