“…In aquaponic systems, there are two types of water employment; blue water resource inputs for aquaculture production [181] and the use of the residues of this production as grey water to fertilize and irrigate plants in different types of aquaponic cultivation beds [182]. Furthermore, aquaponic systems use a lower water input and therefore have a better water use efficiency with a range between 95% and 99% [162], but the water quality of aquaculture discharges and the residue use for food production is critical due to possible food and groundwater contaminations, which can also lead to possible human health risks [98].…”

The expansion of food production is getting more important due to a rising world population, which is relying on food security on a regional and local scale. Intensive food production systems create a negative impact on the regional ecosystem because of agrochemical pollution and nutrient rich water discharges into nearby rivers. Furthermore, these systems are highly depending on regional water resources causing water scarcity and soil erosion due to the overexploitation of natural resources in general. The objective of this article is to review the water usage in the two most water intensive food production systems, agriculture and aquaculture showing lacking areas, like system management and climate change, which must be considered in the implementation of sustainable water footprint. In addition, the review includes an analysis if the combination of both production system into aquaponic food production and the possibilities of water saving. There are a variety of water footprint analyses for crop and aquatic animal production, but there is also a lack of information about the system management including irrigation systems, system cleaning processes, water substitution, pond removal, evaporation due to climate change and especially in aquaculture, the water footprint of industrial elaborated fish feed.

The increasing global demand for aquatic products and decline in wild fisheries pose a challenge in achieving the United Nations’ Sustainable Development Goal 14, which is to conserve and sustainably use marine resources. The depletion of fish populations due to overfishing, destruction of aquatic habitats as well as climate change has adversely affected aquatic ecosystems, which leads to further pressure in establishing food security. To meet the rising demand for fish products, countries have turned to aquaculture, but the industry itself faces many environmental challenges, particularly in wastewater management. This review explores the potential of using biofloc technology (BFT) to treat wastewater. BFT utilises microbial ecosystem processes to remove excess nutrients and acts as a natural “cleaning” mechanism. It transforms organic waste into valuable microbial biomass, which enhances water quality and minimises the ecological footprint of aquaculture. In this way, BFT reduces the amount of solid waste generated, increases the level of dissolved oxygen and creates an environment that is less conducive for the growth of harmful bacteria, thus reducing the need for chemical treatments. This paper also discusses the role of BFT in toxic remediation by analysing the nature and composition of aquaculture wastewater. This study provides a comprehensive overview of the mean values for various water quality parameters in aquaculture and biofloc water, and compares them with aquaculture standards.
