“…It can involve many technical processes, as well as generate synergies with the building holding the crops (Despommier, 2011(Despommier, , 2010Fischetti, 2008;Germer et al, 2011). The method used for RA crops is generally soilless culture systems (SCSs), which are "any method of growing plants without the use of soil as rooting medium, in which the inorganic nutrients absorbed by the roots are supplied via the irrigation water" (FAO, 2013).…”

Analysis of the consumer’s perception of urban food products from a soilless system in rooftop greenhouses: a case study from the Mediterranean area of Barcelona (Spain)

Soilless crops are commonly used in rooftop agriculture (RA) because they easily adapt to building constraints. However, acceptance of the produce derived from this system may be controversial. This paper evaluates consumers' acceptance of food from RA in Mediterranean cities, focusing on the quality of the product, production system, and consumers' motivations. We surveyed 238 respondents on the UAB university campus as potential consumers. The survey was distributed via an Internet-link that was provided along with a sample of tomatoes from RA. The results showed that most people approved the quality of RA products and perceived them to be local and fresh (94%). The respondents exhibited acceptance of soilless-produced tomatoes and considered them to be environmentally better than conventionally produced ones (69%). Cluster analysis revealed that consumers with high income levels and a university education had a better perception of the quality and proposed a higher price for RA products, but no difference was found regarding their environmental perception of this products. Moreover, people who possessed more information about the product also had a higher perception of the quality and production system (it was perceived to be environmentally friendly) and would pay more for them. The main concerns of consumers were related to food safety and the social impact of RA. Additional research is needed to improve the sustainability of RA, and the applied measures should be communicated to potential consumers to enhance their acceptance and success.

“…There are various definitions of vertical farming but to put into simple words, it is a method of urban farming of fruits, vegetables, and grains inside a building in a city or urban center, in which floors are designed to lodge crops with the absence of soil (hydroponics and aeroponics) [5]. Using large multistory buildings to cultivate agricultural produce was an incredible idea by Gilbert E. Bailey, who was an American geologist.…”

The issue of food security has affected the well-being of the people for centuries. Academic and industry experts have been constantly developing alternate and better ways to address this issue. One of such innovations is the concept of vertical and zero acreage farming for providing food security and ensuring environmental sustainability. However, this concept has been in its nascent stage, and its development has been sporadic for many years. This paper uses a comprehensive framework to conduct a feasibility analysis of initiating vertical farming on university campuses, which could set an example for using this technique on a large scale. A case study was conducted on a set of 24 canteens across a university in Wuhan, China for accessing the return on investment and food sufficiency using this technique. By using the central limit theorem, a model was developed after investing in 24 canteens in the university, and various scenarios were analyzed. The breakeven on implementing these farms was about 10 to 20 years, with annual profits reaching $92,000 (592,000 RMB).

“…The challenges seemed too great for the technological state-of-the-art and the idea sank into oblivion. More recently ''vertical farming'' has also been discussed in the USA (Fischetti 2008) although this has brought futuristic architectural designs to the foreground rather than the actual crop production technology. All these approaches aim at crops of higher market value, partly in combination with fish farming and/or animal husbandry.…”

Skyfarming an ecological innovation to enhance global food security

Population growth increases the demand for food and thus leads to expansion of cultivated land and intensification of agricultural production. There is a definite limit to both of these options for food security and their multiple negative effects on the environment undermine the aim for sustainability. Presently the impact of the Green Revolution on crop production is levelling off at high yields attained and even the potential of large scale irrigation programmes and transgenic crops seem to be limited in view of the expected increase in demand for food. Moreover, climate change threatens to affect agricultural production across the globe. Skyfarming represents a promising approach for food production that is largely environment independent and therefore immune to climate change. Optimal growing conditions, shielded from weather extremes and pests are aimed at raising plant production towards the physiological potential. Selecting rice as a pioneer crop for Skyfarming will not only provide a staple for a large part of the global population, but also significantly reduce the greenhouse gas emission caused by paddy cultivation. Multiplication of the benefits could be achieved by stacking production floors vertically. In Skyfarming the crop, with its requirements for optimal growth, development and production, determines the system's design. Accordingly, the initial development must focus on the growing environment, lighting, temperature, humidity regulation and plant protection strategies as well as on the overall energy supply. For each of these areas potentially suitable technologies are presented and discussed
