“…As a result, individuals evaluated the United States, China, Thailand, and Romania through the lens of numerous prior studies. In order to enhance comprehension of the correlation between escalating energy consumption and economic expansion, scholars have investigated decoupling across multiple domains and employing diverse methodologies, encompassing energy production and consumption [ 19 , [67] , [68] , [69] , [70] , [71] , [72] ]. In this study, the A&BD method is employed to investigate the Topia decomposition of energy generation and consumption.…”

“…Also, some authors [ 10 ] concluded that the lack of “know-how” and proper real-time water quality monitoring infrastructure could be a significant drawback for integrating aquaponics techniques into already existing RAS. According to other studies [ 11 , 12 ], the prediction of crop yield could improve significantly the production and commercialization strategy of aquaponic facilities, increasing their competitiveness and maximizing food supply at a suitable time and in the places where the market demand for food products rises.…”

“…Also, forecasting models for fish and plant growth can maximize the efficiency of the facility’s business plan, facilitating marketing, distribution, and supply operations. Several studies already demonstrated that forecasting models such as ARIMA, LSTM or Holt were successfully used in the fisheries and aquaculture sector [ 12 , 38 , 39 , 40 , 41 ]. However, no studies were performed for forecasting the growth of sturgeons reared in RAS.…”

“…The main types of aquaponic module setups, mentioned also by other authors [ 42 , 43 ], are deep water culture (DWC), nutrient film technique (NFT), and flood-and-drain (F&D) substrate systems. However, a recent study [ 12 ] revealed that the aquaponic substrate technique assures the highest rate of return, compared to DWC and NFT techniques. Considering that, according to various research studies [ 8 , 10 ], the cost of substrate represents a significant percentage of total investment costs performed to integrate aquaponics into already existing RAS, several attempts have been made by other authors [ 44 , 45 , 46 ] in order to identify a suitable material which should accomplish both economic and environmental sustainability desideratum.…”

Here, we aim to improve the overall sustainability of aquaponic basil (Ocimum basilicum L.)-sturgeon (Acipenser baerii) integrated recirculating systems. We implement new AI methods for operational management together with innovative solutions for plant growth bed, consisting of Rapana venosa shells (R), considered wastes in the food processing industry. To this end, the ARIMA-supervised learning method was used to develop solutions for forecasting the growth of both fish and plant biomass, while multi-linear regression (MLR), generalized additive models (GAM), and XGBoost were used for developing black-box virtual sensors for water quality. The efficiency of the new R substrate was evaluated and compared to the consecrated light expended clay aggregate—LECA aquaponics substrate (H). Considering two different technological scenarios (A—high feed input, B—low feed input, respectively), nutrient reduction rates, plant biomass growth performance and additionally plant quality are analysed. The resulting prediction models reveal a good accuracy, with the best metrics for predicting N-NO3 concentration in technological water. Furthermore, PCA analysis reveals a high correlation between water dissolved oxygen and pH. The use of innovative R growth substrate assured better basil growth performance. Indeed, this was in terms of both average fresh weight per basil plant, with 22.59% more at AR compared to AH, 16.45% more at BR compared to BH, respectively, as well as for average leaf area (LA) with 8.36% more at AR compared to AH, 9.49% more at BR compared to BH. However, the use of R substrate revealed a lower N-NH4 and N-NO3 reduction rate in technological water, compared to H-based variants (19.58% at AR and 18.95% at BR, compared to 20.75% at AH and 26.53% at BH for N-NH4; 2.02% at AR and 4.1% at BR, compared to 3.16% at AH and 5.24% at BH for N-NO3). The concentration of Ca, K, Mg and NO3 in the basil leaf area registered the following relationship between the experimental variants: AR > AH > BR > BH. In the root area however, the NO3 were higher in H variants with low feed input. The total phenolic and flavonoid contents in basil roots and aerial parts and the antioxidant activity of the methanolic extracts of experimental variants revealed that the highest total phenolic and flavonoid contents were found in the BH variant (0.348% and 0.169%, respectively in the roots, 0.512% and 0.019%, respectively in the aerial parts), while the methanolic extract obtained from the roots of the same variant showed the most potent antioxidant activity (89.15%). The results revealed that an analytical framework based on supervised learning can be successfully employed in various technological scenarios to optimize operational management in an aquaponic basil (Ocimum basilicum L.)-sturgeon (Acipenser baerii) integrated recirculating systems. Also, the R substrate represents a suitable alternative for replacing conventional aquaponic grow beds. This is because it offers better plant growth performance and plant quality, together with a comparable nitrogen compound reduction rate. Future studies should investigate the long-term efficiency of innovative R aquaponic growth bed. Thus, focusing on the application of the developed prediction and forecasting models developed here, on a wider range of technological scenarios.

“…With sensors and robotised solutions, vertical farms can become more effective and efficient [18]. Naturally, vertical farming faces difficulties too, such as high start-up and operating costs and long payback periods (the application of renewable resources could significantly influence them) [19][20][21][22][23]. One of the most significant disadvantages of this indoor farming is the limited crop types.…”

Today’s rapidly changing economic and social environment requires many new and sustainable solutions for the agricultural sector, in particular in terms of achieving higher yields and conserving arable land. However, the latest technologies and innovative ideas could answer these issues and even support a smooth transition into a green economy. The current work studies one of the best solutions—consumer acceptance. Even though vertical farming is relatively widely researched, the potential clients are seldom analysed. The applied systematic literature review (PRISMA) approach revealed various vital characteristics related to the consumers based on academic publications. According to the selected studies’ results, consumers’ adoption of innovative technology is most influenced by prior knowledge of vertical farming and the importance of sustainability. Some studies found further correlations between age and gender regarding adoption, while others did not investigate these or found their role irrelevant. Most consumers found vertical farming “too artificial” and identified this as a major inhibiting factor. However, further investigation has shown that appropriate and informative marketing could significantly increase the understanding of the concept and, through this, the acceptance and widespread practical application of the innovation. In addition, the authors want to use the current work to highlight the unsettled state of vertical management. It can be concluded that new regulations could increase confidence in vertical farming, which could be further supported by the theoretical model developed in this study, thus allowing the creation of a fully traceable product chain.
