Global environmental, social and economic challenges drive the need for new improved solutions food production consumption. Food within a sustainability corridor requires innovations exceeding traditional paradigms, acknowledging complexity arising from sustainability. However, there is lack of knowledge about how to direct further activities, develop technologies as potential questions related climate change, loss soil fertility biodiversity, scarcity resources, shortage drinking water. One...
Abstract Research and practice during the last 20 years has shown that urban agriculture can contribute to minimising effects of climate change by, at same time, improving quality life in areas. In order do so most effectively, land use spatial planning are crucial as obtain maintain a supportive green infrastructure secure citizens' healthy living conditions. As people today trend more towards sustainable city centres offer fresh locally produced food, cities become again places for growing...
Nutrients that are contained in aquaculture effluent may not supply sufficient levels of nutrients for proper plant development and growth hydroponics; therefore, they need to be supplemented. To determine the required level supplementation, three identical aquaponic systems (A, B, C) one hydroponic system (D) were stocked with lettuce, mint, mushroom herbs. The Nile tilapia. System A only received derived from fish feed; B feed as well weekly supplements micronutrients Fe; C same...
Aquaponics (AP) is a food production system that combines hydroponic (HP) crop with recirculating aquaculture. Different types of systems have been used for growing crops in aquaponics. However, very few studies compared their suitability and efficiency an aquaponic context. The study presented here compares tomato yield, morphological (external) biochemical (internal) fruit quality, overall plant vitality from three different HP (nutrient film technique, drip irrigation system, floating...
Abstract The aquaponic principle is the coupling of animal aquaculture (e.g. fish) with plant production vegetables) for saving resources. At present, various definitions aquaponics exist, some bearing risk misinterpretation by dismissing original meaning or being contradictory. In addition, there no standard terminology aspects between subsystems. this study, we addressed both issues. (1) We developed new revised that are summarised by: Aquaponic farming comprises (which couples tank‐based...
In this preliminary article we present data on plant nutrient concentrations in aquaponic systems, and compare them to “standard” hydroponic solutions. Our shows that the supplied by fish system are significantly lower for most nutrients, compared systems. Nevertheless, plants do thrive solutions have levels than This is especially true green leafy vegetables rarely need additional nutritional supplementation. It concluded highly complex of aquaponics, special care has be taken, via...
Aquaponics is a production system based on the dynamic equilibrium between fish, plants, and microorganisms. In order to better understand role of microorganisms in this tripartite relationship, we studied bacterial communities hosted eight aquaponic aquaculture systems. The were analyzed by 16S rRNA gene deep sequencing. At phylum level, from all systems relatively similar with predominance Proteobacteria Bacteroidetes. genus however, present sampled more heterogeneous. biofilter samples...
This paper uses an expert-based methodology to survey the barriers and strategies related implementation of nature-based solutions (NBS). The ambition is offer a bird's eye overview difficulties encountered by NBS deployment ways overcome them. With wide participation 80 experts from COST Action Circular City, we identify specific 35 pre-defined following four categories: Vertical Greening Systems Green Roofs; Food Biomass Production; Rainwater Management; Remediation, Treatment, Recovery....
The mobilization of nutrients from fish sludge (i.e., feces and uneaten feed) plays a key role in optimizing the resource utilization thus improving sustainability aquaponic systems. While several studies have documented aerobic anaerobic digestion performance aquaculture sludge, impact digestate on plant growth has yet to be understood. present study examines either an or effluent lettuce growth, by enriching mixture tap water with supernatants both batch reactors. plants grown hydroponic...
The aim of this study was to analyze current practices in commercial urban rooftop farming (URF). In recent years, URF has been experiencing increasing popularity. It is a practice that well-suited enhancing food security cities and reducing the environmental impact results from long transportation distances are common conventional agriculture. To date, most initiatives have motivated by social educational factors rather than creating large sustainable production systems cities. operation...
International aquaponic production has increased over the past decade, but less is known about research activities and facilities operating in Europe. We conducted an online survey to get a better idea Europe, focusing on five areas of aquaponics (i.e., demographics, used, fish crops produced, funding sources, personal or company priorities for further development). The 68 respondents were distributed among 21 European countries, 43% working at university, 19% commercial producers. Only...
Aquaponics is an evolving closed-system food production technology that integrates recirculating aquaculture with hydroponics. In this paper we give a brief literature overview of the sustainability aspects aquaponics by discussing its social, environmental, and economic impacts in different potential settings. The might be applied to commercial or community based urban production, industrial scale rural areas, small farming developing countries as systems for education decoration inside...
A commonly addressed aspect of urban planning involves the integration nature-based solutions (NBS). Before applying NBS, acquiring stakeholders' viewpoints, e.g., city councils, local governments, and academia, contributes to successful application thus mitigation global challenges such as climate change, loss biodiversity, water, food scarcity. The present study explores how stakeholders across Europe view role NBS in planning. thematic analysis was conducted identify patterns, themes,...
In recent years, aquaponics has been receiving increased interest globally as a commercial food production technology and start-up companies have formed in most European countries. Between 2014 2018, the European-funded COST Action FA1305 “The EU Aquaponics Hub-Realising Sustainable Integrated Fish Vegetable Production for EU” created strong network of researchers entrepreneurs. However, surveys show that aquaponic Europe is still very limited, few are economically viable. order to obtain...
Urban agriculture (UA) plays a key role in the circular metabolism of cities, as it can use water resources, nutrients, and other materials recovered from streams that currently leave city solid waste or wastewater to produce new food biomass. The ecosystem services urban green spaces infrastructures productivity specific agricultural technologies have been discussed literature. However, understanding input output (I/O) different nature-based solutions (NBS) is not yet sufficient identify...
Aquaponics combines hydroponic crop production with recirculating aquaculture. These systems comprise various compartments (fish tank, biofilter, sump, table, radial flow settler and anaerobic digester), each their own specific environmental pressures, which trigger the formation of unique microbial communities. Triplicated aquaponic were used to investigate community composition during three lettuce growing cycles. The sampling individual allowed patterns be generated using amplicon...
