“…Although this is country specific, for land-based farms, electricity is often obtained from the central grid, while cage-based farms generally use diesel and other fossil fuels. 159 The influence of the electricity source on the environmental footprint has been shown for RAS as well as for flow-through and bivalve systems, 131,134 hence the importance of a transition to renewables or low-impact energy sources in most energy-intensive systems. This is for example possible via T A B L E 1 Examples of integrated aquaculture systems and the main rearing technologies for fed aquaculture systems.…”

A circular economy is considered one way to reduce environmental impacts of human activities, by more efficient use of resources and recovery, resulting in less waste and emissions compared to linear take‐make‐dispose systems. Muscat et al. developed five ecological principles to guide biomass use towards a circular economy. A few studies have demonstrated environmental benefits of applying these principles to land‐based food systems, but to date, these principles have not been explored in aquaculture. The current study expands on these principles and provides a narrative review to (i) translate them to aquaculture, while identifying implications for the main species and production systems, and (ii) identify the main pathways to make aquaculture more circular. We show that the underlying concepts of the ‘safeguard’, ‘entropy’, and ‘recycle’ principles have been well researched and sometimes well implemented. In contrast, the ‘avoid’ and ‘prioritise’ principles have been explored much less; doing so would provide an opportunity to decrease environmental impacts of aquaculture at the food‐system level. One example is prioritising the production of species that contribute to food and nutrition security, have low environmental impacts and thinking at wider food system scale to avoid feed‐food competition in aquaculture. We identified six priorities that could make aquaculture more circular: (i) increase production and demand for the most essential species, (ii) decrease food loss and waste at farm and post‐harvest stages, (iii) support nutrient recycling practices at multiple scales, (iv) adapt aquafeed formulations, (v) inform consumers about benefits of species of low trophic levels and other environmentally friendly aquatic foods, and (vi) address urgent research gaps.

“…However, it should always be kept in mind that affordable (with payback time varying from 6 months to 3 years in Africa depending on crops grown and number of crop cycles) solar-powered irrigation can lead to ground water sources exhaustion. In hydroponic [84] and aquaculture [85] farms, AV could be used to power heat and mass transfer processes optimisation [86].…”

Agrivoltaics (Agri-PV, AV) – the joint use of land for the production of agricultural products and energy – has recently been rapidly gaining popularity, as it can significantly increase income per unit of land area. In a broad sense, AV systems can include converters of not only solar, but also energy from any other local renewable source, including bioenergy. Current approach to AV represents an evolutionary development of agroecology and integrated PV power supply to the grid. That results in nearly doubled income per unit area. While AV could provide a basis for revolution in large-scale unmanned precision agriculture and smart farming which is impossible without on-site power supply, chemical fertilisation and pesticides reduction, and yield processing on-site. These approaches could change the logistics and the added value production chain in agriculture dramatically, and so, reduce its carbon footprint. Utilisation of decommissioned solar panels in AV could make the technology twice cheaper and postpone the need for bulk PV recycling. Unlike the mainstream discourse on the topic, this review feature is in focusing on the possibilities for AV to be stronger integrated into agriculture that could also help in relevant legal collisions (considered as neither rather than both components) resolution.

“…Expansion of these into Africa is a priority of the CGIAR systems and its WorldFish center (http://worldfishcenter.org). With the expansion of aquaculture technologies and global economies, land (e.g., recirculating aquaculture systems, RAS) and ocean‐based aquaculture food systems developments will need to be integrated with emerging renewable energy systems at all scales (Buck & Langan, 2017; Scroggins et al, 2022; Vo et al, 2021). In addition, as tourism is estimated to account for upwards of 30% of the global economy, development of aquaculture tourism will not only assist in the economic viability of farming livelihoods but in the education of communities in areas of the world where aquaculture is new.…”
