“…The studies related to various technological/process development of hydroponics are available in the literature (Huo et al, 2020;Jung and Kim, 2020;Awad et al, 2017;Baddadi et al, 2019;Silva et al, 2018;Vinci and Rapa, 2019), and most of them cited the development and varying benefits of hydroponic systems at different stages. For instance, Huo et al (2020) experimented with micro algae's effect on food production through hydroponics. They concluded that the co-cultivation of crops with micro algae could be more economically sustainable and eco-friendly.…”

PurposeThis study aims to evaluate a hydroponic farm (through nutrient film technique) while considering uncertainty, sustainability and the system's utility in the dominant desert geography. The idea of the hydroponic farm is to allow individuals/businesses to grow plants. Given the geographical condition, the hydroponic system may be useful in the Gulf context and may lead to food security and sustainability. Additionally, the UAE government has initiated several support schemes that can be availed for investing in such businesses that can contribute to the nation's food security.Design/methodology/approachThe hydroponic farm is evaluated using the net present value and real options approach. The authors studied five scenarios: 1. business as usual, 2. 50% subsidy on initial investment through Khalifa funding, 3. 4% premium, 4. Subsidy plus premium and 5. solar panel installation with bore well.FindingsAs per the assumptions and data usage, all the scenarios shows a positive net present value (NPV); Nevertheless, scenarios 4 and 5 report the significant highest net present and delay value.Research limitations/implicationsThis study has environmental, economic and social implications. Lower imports indirectly lead to lower carbon footprints. The local production of food ensures higher employability in the sector and increase in local consumption. Additionally, fresh food consumption is directly associated to good health.Practical implicationsSupportive policies such as subsidies through Khalifa funding may accelerate the expansion of such projects through domestic and foreign investments. One of the important takeaway from the study is to invest in the training of the workforce.Social implicationsGiven the geographical condition, the UAE usually depends on food imports. If the hydroponic farms become popular, the residents will have access to fresh vegetables and fruits. Higher engagement in agriculture activities also ensures a significant increase in agriculture-related businesses and higher employability.Originality/valueThe study adds novelty to the literature because the effect of Khalifa funding and investment analysis on solar (wells) has not been evaluated in any hydroponic studies. We presented the results with tornado graphs using NPV risk and real options approach in the Gulf context. The study represents functional scenarios that were previously not found in the literature.

“…The application of microalgae has been widely studied in wastewater treatment for nutrients recovery. 4,16 Unlike traditional methods, such as active sludge and physical flocculation, microalgae-based wastewater treatment can convert nutrients in wastewater into value-added biomass, realizing the nutrients recovery. As shown in Table 1, nutrients in aquaculture effluent, such as nitrogen, phosphorus, and carbon, can be effectively recovered by microalgae for biomass accumulation.…”

“…3 The study by Huo et al (2020) revealed that, with the addition of microalgae, the content of DO can be maintained at a higher level. 16 The aerobic conditions can promote the growth of some aerobic bacteria, particularly nitrifying bacteria, creating a better environment for aquatic animals. Previous studies discovered that a high content of DO in an appropriate range can be beneficial to fish growth, reproduction, and survival.…”

The application of microalgae biotechnology, which can recover nutrients from wastewater, improve water quality, and feed some aquatic animals, is becoming an emerging trend in the development of eco-friendly aquaculture. Previous studies explored a variety of models to support the use of microalgae in aquaculture practice, verifying the feasibility and advantages of microalgae-based aquaculture. However, a couple of bottlenecks and problems jeopardizing the application of microalgae biotechnology in aquaculture are discovered in the research and industrial practice. This work, hence, summarizes the research progress and the current opinions relating with the microalgae-based aquaculture and proposes some critical thoughts about the bottlenecks challenging its industrial implementation.
