This chapter focuses on peri-urban food production and provisioning as overlooked aspects of urban sustainability in developed countries. It discusses how agricultural production for urban consumption in peri-urban areas is often abandoned and replaced by urban sprawl and recreational activities. The chapter elaborates on the multiple dimensions of sustainable local food systems as an alternative to globalized systems, including results from a European research project with a case study from a peri-urban region in Gothenburg, Sweden.

This collective case study investigated how two Ohio school-based agricultural educators use school gardens to teach science, including socioscientific issues (SSI). Qualitative data from semistructured interviews revealed that both teachers utilized applied science teaching methods and expressed frustrations regarding the difficulty of meeting mandated science learning standards. Although controversial topics were often integrated, fidelity to the SSI framework did not appear to be utilized.

This paper aimed to assess factors contributing to more successful integration of urban agriculture in some cities and to introduce agro-ecology practices in public green spaces and community gardens through landscape assessment and map-based comparison. A key problem identified was the lack of motivation among planners to integrate urban agriculture into urban plans, preventing these green structures from becoming part of the city's landscape and dynamics. The sustainability of food systems was concluded to depend on the city's planning strategy and governance policies.

This article explores water resource management in Addis Ababa's condominium housing and urban agriculture cooperatives to identify challenges and potentials for water-resilient livelihoods. Findings indicate both communities are heavily affected by water stress, with farming communities being vulnerable due to natural asset dependence but more flexible than condominium residents facing malfunctioning infrastructure. Potential for resilience exists if policy frameworks integrate local situations with landscape-based stormwater management.

Désiré Jean‐Pascal Lompo, Emmanuel Compaoré, Michel Papaoba Sédogo, Martina Melapie, Charles Bielders, Eva Schlecht, Andreas Buerkert · Nutrient Cycling in Agroecosystems · Burkina Faso (Bobo Dioulasso)

This study investigated nutrient management in six urban vegetable gardens in Bobo Dioulasso, Burkina Faso, quantifying nitrogen (N), potassium (K), and carbon (C) fluxes and balances. Inputs of N and K significantly exceeded recommended amounts, leading to substantial horizontal annual surpluses of 1013 kg N ha−1, 879 kg K ha−1, and 25 t C ha−1. While total balances for N and K were positive, the total balance for C was negative, indicating an environmental tradeoff due to excessive nutrient input.

This study surveyed the implementation cost and presented the step-by-step operation of small-scale aquaponic systems for family agriculture and peri-urban areas. As a descriptive and experimental research, a practical experiment involved feeding 27 kg of fish, with their waste nourishing 144 Crespa Lettuce seedlings. The findings suggest that aquaponic systems tend to be a sustainable alternative due to low implantation costs, practical management, and healthier production from organic plant nutrition and the non-use of chemicals.

This study assessed the economic vulnerability of 289 urban farm households in three states of South-south Nigeria using vulnerability index analysis. The results indicated a high level of economic vulnerability among urban farmers, primarily caused by lack of access to formal credit, lack of land, low asset value, and low farm income. Households entirely dependent on farm income were 66% more likely to be vulnerable to economic shocks.

A six-week study in summer 2017 in urban gardens in California, conducted with volunteer gardeners, examined how ambient temperature, water use, vegetation, ground cover, and soil management affect soil moisture gain and loss rates. The research found that plot-level soil management is essential for maintaining stable water levels within garden soils. Plots with better soil quality, indicated by higher water holding capacity, experienced slower rates of soil moisture gain after watering but also slower rates of soil moisture loss, resulting in more stable moisture profiles over time.

This study investigated the educational implications of Nurpurum School, a 12-year alternative school pursuing the value of "transition," through a case study. Participant observation, interviews, and local data collection revealed that after the 2011 Fukushima nuclear accident, the school restructured its curriculum around the theme of "ecological transition in education," implementing a "Transition Village Project" focused on urban agriculture and appropriate technology. This education was concluded to shift meaning from "made" education to "making" education, from teacher-centered to co-teaching and learning relationships, and from competition to education for coexistence and symbiosis.

This survey evaluated 10,078 hectares of unmanaged land in Lasiana, Kupang city, Indonesia, to assess its capability for urban agriculture. The study found that two land units were classified as Class III land capability due to limiting factors such as soil depth, erosion level, soil fertility, drainage, and stoniness. Recommendations for land management included increasing soil depth and applying urban forest or urban farming development with multifunctional land uses.

Marit Rosol · · Global

This chapter discusses the politics of urban community gardening, positioning it ambiguously between neoliberal/austerity urbanism and progressive urban politics. It argues that urban community gardening can reinforce neoliberal urbanism through land use struggles and gentrification, the role of volunteering in neoliberal urban governance, and governing through community and technologies of the self. The continuous emphasis on self-help in urban green spaces is problematic when civic engagement focuses exclusively on certain groups and values.
