The "Sunlight, Soil & Shit (De)Cycle" project, presented by SymbioticA in February 2022, is a performative experiment exploring agricultural technology (AgTech) and its aim to remove natural elements like sunlight, soil, and organic waste from food production. This project considers whether the precursor to sustainable food systems will be the creation of a metabolic rift, where the means of production grow ever distant from nature. It highlights a critical environmental tradeoff by questioning the separation of humans from nature in technological farming.

This chapter explores the role of agroecology in smart cities and investigates how Information and Communications Technologies (ICT) could spread agroecological approaches to boost urban agriculture. Smart cities are criticized for their inability to build just and inclusive environments, and ICT alone cannot guarantee sustainable development. While agroecology enhances ecosystem services and human well-being, its introduction in urban ecosystems is complex. The chapter suggests ICT could provide tools to enhance dwellers' competencies in practicing agroecology, ultimately exploring how smart urban agriculture contributes to food sovereignty and ecosystem service maintenance.

This study investigated the effects of agrivoltaic systems on rooftop microclimates and PV efficiency. ENVI-met simulations showed that PV temperatures in plots with crops below the PV system were 2.83 °C lower on sunny days and 0.71 °C lower on cloudy days, leading to a 1.13–1.42% and 0.28–0.35% improvement in PV efficiency, respectively. Data from a physical prototype indicated that evaporative cooling reduced ambient temperatures, with the agrivoltaic system generating 3.05–3.2% more energy daily compared to a control without crops.

This paper aims to extend the theory of synchronous generative development, which balances human and environmental well-being, towards practical application in sustainable development projects. The theory is extended by referencing research on multilevel pragmatics, competing signals, commitment processes, technological mediation, and psychomotor functioning, and is related to human-driven biosocial-technical innovation through the example of digital twins for agroecological urban farming. However, practical examples in the paper suggest that counterproductive complexity can arise from situated entropy amidst biosocial-technical innovations, even when compatible with synchronous generative development.

Motivated by the growing trend of urban agriculture, this study built an IoT system for monitoring and analyzing climatological variables relevant to urban agriculture crops. Development followed four phases: selection of tools and technologies, IoT system architecture design, prototype construction, and a case study on a lettuce crop. The resulting system used open-source hardware and software tools within the conventional four-layer IoT architecture (capture, storage, analysis, visualization). Its stated advantage over existing solutions is the use of portable single-board-computer (SBC) platforms and the inclusion of machine-learning models in the analysis layer. The case study, carried out on a home lettuce crop, concluded that the chosen tools adequately captured, monitored, and analyzed climatological variables of interest, and that the analysis models can be customized to a crop's agroclimatic characteristics, making them useful for decisions related to crop physiology.

A mixed-methods study (International Journal of Environmental Research and Public Health, 2022) surveyed 325 villagers across 13 communities in seven Thai provinces, combining the Theory of Reasoned Action, Theory of Planned Behavior, and Health Belief Model with techniques including crosstab analysis, stepwise multiple linear regression, one-way ANOVA, multinomial logistic regression, decision tree analysis, and descriptive content analysis. Attitude, perceived benefits, and perceived readiness significantly and positively influenced adoption of urban agriculture. Among villagers who owned agricultural land, behavioral control and social norms drove continued practice; for other groups, perceived readiness and communication were the key drivers. The study proposes communication guidelines based on the EAST framework (easy, attractive, social, timely) delivered through a Critical Participatory Action Research process.

This review covers soilless cultivation, in which plants are grown without soil as a rooting medium, including hydroponic, aeroponic, vertical farming, and other systems. It states that in greenhouses and tunnels, about 3.5% of the world's crops are produced using soilless, hydroponic methods. It notes that hydroponic farms can be built in deserts, the Arctic, and other difficult-to-farm places, and that the absence of soil means fewer insects and weeds. Crops grown in soilless systems include vegetables, fruits, flowers, and medicinal plants, using inorganic or organic growth media such as bark, coconut coir, coconut soil, fleece, marc, and peat. The review characterizes soilless culture as a relatively recently developed approach to agricultural development that is nonetheless difficult to put into practice.
