“…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.

“…Water Recirculation Systems (RAS) incorporate water treatment and reuse 90-95% of the required water. RAS offers a variety of important advantages when compared to open tank cultivation, such as reduced water and land requirements, parameter control that allows optimization of production conditions, rigorous waste management, and food safety benefits (TIMMONS;EBELING, 2013;CLOUGH et al, 2020).…”

Sustainability, over the years, has become one of the main concerns of modern society (PIRES et al., 2014). In addition, with population growth, increased demand for protein and the impacts caused by anthropogenic action continuously modifying the environment (SILVA, 2018), one of the main challenges of the agricultural sectors is a sustainable production of food, aiming at food security and reducing the environmental impacts generated by the activity (FAO, 2018). Therefore, for sustainable development to occur, it is necessary that there is a harmonization between economic development, preservation of the environment, social justice (access to quality public services), quality of life and the rational use of nature's resources.

“…Despite the growing body of research on aquaculture and RAS in Africa, there is insufficient focus on the integration of digital technologies for water management purposes (Obiero, 2019). However, some studies and reports (Clough et al, 2020;Antony & Sweeney, 2019) provide valuable insights into the potential applications and benefits of digital water tools in African aquaculture systems. Clough et al (2020) established a trial Nile Tilapia (Oreochromis niloticus) hatchery in Kisumu, Kenya, employing locally adapted RAS.…”

Food and nutrition insecurity, affecting 30% of the global population in 2020, poses a significant challenge to achieving Sustainable Development Goal (SDG) 2 - Zero Hunger. Urbanization, particularly in sub-Saharan African cities e.g. Lagos, Nigeria, exacerbates these issues, impacting resources and contributing to informal settlements. There is emphasis on innovative solutions in urban farming, with Recirculating Aquaculture Systems (RAS) emerging as one of the promising approach due to its efficiency in space and capital utilization. However, maintaining optimal conditions in RAS, crucial for SDG 2 and 11, requires robust water quality monitoring. This study explores the availability of digital tools for water quality monitoring in small-scale urban RAS, evaluating handheld devices and IoT sensors' reliability through t-test statistical method. The results aim to guide practitioners in selecting effective monitoring tools, contributing valuable insights for sustainable aquaculture in urban areas, particularly in sub-Saharan Africa, where access to affordable digital solutions is pivotal for success and can attract youth to agri-food technologies.
