A 2012 pilot experiment in Paris, France, tested simple rooftop gardening systems using local urban organic waste as crop substrates. Measurements of production levels and heavy metal content in crops and substrates showed high crop production with limited inputs, low heavy metal pollutants in edible parts, and positive yield influence from layered substrates and earthworm inoculation. These results suggest rooftop gardening is feasible and has potential for urban resiliency, though further assessment of roof types, pollution levels, and sustainability is needed.

This doctoral thesis explores the development of eco-citizenship competence in school gardens, specifically through collaborative technological design activities. Elementary school students designed and assembled an irrigation system for their school garden over ten activities. Analysis showed students integrated elements from various design proposals without exclusive opposition, and that design conflicts led to a more dynamic and complex garden model. The study also found differences in argumentative discourse structure and dynamics between scientific argumentation and technological design activities.

This study examines landscape arrangement through an urban farming program as one way to address the shortage of green open space in a dense urban kampung in Malang, Indonesia. Urban farming is presented as improving both ecological quality and the visual aspect of the environment while also having potential as economic activity. For the densely populated Kampung Tembalangan, the landscape planning process proceeded through evaluation of existing conditions, analysis of potential, and consideration of alternative solutions. The results showed that the urban farming techniques practiced in the kampung can function simultaneously as architectural aesthetic elements and create space serving multiple needed functions.

This study compared crop yields, quality and labor input for subirrigated planters (SIPs), a sack-garden variant, and two conventional raised beds over one season at one location, growing cayenne pepper, cherry tomatoes and kale. Both the SIP beds and conventional beds with a soilless growing medium were more productive than conventional beds with a topsoil-and-compost mix, and tomato yield in the SIP without a root barrier exceeded both conventional beds. Most of the higher-cost beds generated a positive revenue stream in the first season, suggesting that investing in SIPs or in soil suitable for raised beds is worth the higher initial cost.
