“…This microflora can have significant beneficial effects on plant growth and organic molecules' assimilation. Hence, some aquaponics investigators report similar or even better yield than hydroponics for some crops, despite lower concentrations of mineral nutrients [1,71,[72][73][74][75].…”

Abstract:The world is facing a number of serious problems of which population rise, climate change, soil degradation, water scarcity and food security are among the most important. Aquaponics, as a closed loop system consisting of hydroponics and aquaculture elements, could contribute to addressing these problems. However, there is a lack of quantitative research to support the development of economically feasible aquaponics systems. Although many studies have addressed some scientific aspects, there has been limited focus on commercial implementation. In this review paper, opportunities that have the potential to fill the gap between research and implementation of commercial aquaponic systems have been identified. The analysis shows that aquaponics is capable of being an important driver for the development of integrated food production systems. Arid regions suffering from water stress will particularly benefit from this technology being operated in a commercial environment. OPEN ACCESSSustainability 2015, 7 4200

“…This feature makes this production type very sustainable in terms of nutrient and water recycling. In this way, farmers can save money and effort on fertilizing plants (Savidov et al 2007). For an implementation in urban areas, the weight of the system is particularly important and could be a disadvantage, for instance, concerning an installation on a rooftop.…”

Global food production faces great challenges in the future. With a future world population of 9.6 billion by 2050, rising urbanization, decreasing arable land, and weather extremes due to climate change, global agriculture is under pressure. While today over 50 % of the world population live in cities, by 2030, the number will rise to 70 %. In addition, global emissions have to be kept in mind. Currently, agriculture accounts for around 20-30 % of global greenhouse gas emissions. Shifting food production to locations with high demands reduces emissions and mitigates climate change. Urban horticulture increases global food production by exploiting new locations for cultivation. However, higher land prices and urban pollution constrain urban horticulture. In this paper, we review different urban cultivation systems throughout the world. Our main findings from ecological, economical, and social aspects are: (1) Urban horticulture activities are increasing globally with at least 100 million people involved worldwide. With potential yields of up to 50 kg per m 2 per year and more, vegetable production is the most significant component of urban food production which contributes to global food security. (2) Organoponic and other low-input systems will continue to play an important role for a sustainable and secure food production in the future. (3) Despite the resource efficiency of indoor farming systems, they are still very expensive. (4) Integrating urban horticulture into educational and social programs improves nutrition and food security. Overlaying these, new technologies in horticultural research need to be adopted for urban horticulture to increase future efficiency and productivity. To enhance sustainability, urban horticulture has to be integrated into the urban planning process and supported through policies. However, future food production should not be "local at any price," but rather committed to increase sustainability.

“…Phytoplankton and bacterial uptake is another method to assimilate nitrate into cellular tissue (Gross et al, 2000). Aquaponics is another way to assimilate NO 3 into fresh, marketable plant biomass, as lettuce, tomato, basil and other crops (Graber & Junge, 2009;Rico-García et al, 2009;Savidov et al, 2005).…”
