This article examines permaculture design, developed by Bill Mollison and David Holmgren, not only as an application of systems theory but also as a form of figurative, ecological reasoning. Permaculture challenges the division between theory and practice, or rationality and sensibility, inextricably linking these modes of knowledge in explorations of patterns. Specifically, it describes permaculture design thought through three aspects: visual thinking in patterns, the role of radical imagination and speculation, and systems theory thought drawing from the Gaia hypothesis.

Research at the University of British Columbia (UBC), Canada, investigated whether rooftop gardens could reduce greenhouse gas emissions and food transportation carbon emissions. While edible landscapes could potentially assist with climate goals, they require careful selection of crops, buildings, and resources. Preliminary calculations indicated that rooftop and community gardens would do very little to reduce the UBC campus's dependency on imported food.

This is a review of Lorraine Johnson's book "City Farmer: Adventures in Urban Food Growing" by Michael Classens. Johnson argues that small-scale 'city farmers' are the vanguard of an emerging transformation of the contemporary food system, despite urban farming being more prefigurative than productive in aggregate. The book reveals the potential in interstitial urban spaces for food production and urges a reimagining of our relationship to cities as farms.

Haijian Feng, Zhongxue Zhou · Zhongguo shengtai nongye xuebao · China (Xi'an)

This study analyzed the spatial differentiation of urban agricultural functions in the Xi'an metropolitan zone, China, using ArcGIS grid technology at a 0.5 km × 0.5 km scale. Findings showed that production-economic function increased from southwest to northeast and from near-suburban to mid-far-suburban plains, while employment function was lower in the Qinling mountainous area than in plains. Cultural-leisure function exhibited a concentric spatial structure, and ecological function decreased from the urban periphery to the center, with severe fragmentation of ecological function value distribution areas.

Taibat Lawanson, Olabode Orelaja, Michael Simire · African Journal of Science Technology Innovation and Development · Nigeria (Lagos)

This case study investigated the effects of climate change on agricultural activities in the Igbe Farming Community, Lagos, Nigeria, by surveying 161 farmers. The study found that most migrant farmers leased plots annually or biennially and made marginal profits of $200 to $350 per farming cycle. Erratic weather patterns and aggressive urban growth were major challenges, leading 48% of respondents to engage in informal enterprises.

This paper describes urban agriculture using the popular 2013 term "gaodashang" (high-end, atmospheric, and classy). Urban agriculture is an industry in urbanized areas that utilizes pastoral landscapes, natural ecology, and environmental resources, combining agricultural, forestry, animal husbandry, and fishery production, agricultural business activities, rural culture, and rural life. It provides places for people to engage in leisure tourism, experience agriculture, and understand rural areas, integrating the three functions of agricultural production, life, and ecology.

Dominique Hes, Chrisna du Plessis · · Global

This chapter examines how the Living Building Challenge (LBC) supports transformation towards an ecological worldview, focusing on its "Petals." The LBC's Site Petal determines where and what type of development can be built and how to restore a place, while the Urban Agriculture Imperative requires projects to contribute to local and regional food production. The Energy Petal aims to utilize the site's energy budget, and the Materials Petal is noted for its demanding imperatives.

Ranka Junge, Andreas Graber · Zürcher Hochschule für Angewandte Wissenschaften digital collection (Zurich University of Applied Sciences) · Global

This paper discusses the need for practical tools and a stronger scientific base for sustainable urban farming, noting that visionary schemes often lack current practical application with available technologies. It identifies requirements for urban food production, including high quality, safety, and cost-effectiveness, and suggests innovations in planting, pest control, irrigation, and integration with existing building infrastructures. Aquaponics is presented as having the potential to contribute to all these aspects.

Jan Jansen · · Global

This research explored how insects can add value to urban farming by up-cycling waste streams into high-grade nutrients and compost, focusing on their use as animal feed. Through expert interviews with urban farming practitioners and pet owners (165 respondents, 59 in urban environments), a concept was developed for growing black soldier fly larvae on organic waste to replace meat in carnivorous animal diets, specifically for dogs. Over half of urban respondents indicated no municipal green waste pickup, and over 50% practiced urban farming.
