This study analyzes policy and planning practices for integrating urban agriculture into city land-use planning in Australia. It found that recent planning has overlooked and failed to realize the opportunity of urban agriculture, with regulatory and legal frameworks, including land access, being significant constraints. The study concludes that without direct public policy support and institutional recognition, integrating urban agriculture into Australian cities' development and planning goals is difficult.

The continued existence of agriculture in and near urban areas, such as in Jakarta and Addis Ababa, is an important means to strengthen city resilience. However, its importance is still poorly, or at best intermittently, acknowledged by politicians and urban planners, who are inspired by visions of "modern" cities where agriculture is considered a negligible activity.

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 chapter examines urban agriculture (UA) through six dimensions: spatial, economic, social, environmental, practical, and intellectual. It highlights UA's financial returns, production volumes, sustainability benefits, and social value. The chapter concludes that a clearer understanding of UA's value within governance, academia, and communities is imperative to overcome regulatory barriers.

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.

Community gardens can serve as important local greenspaces to address environmental degradation and educate individuals about the importance of food and the environment. However, certain barriers need to be overcome and addressed before community gardens are successfully implemented. Participation and interaction within community gardens may provide a pathway to long-term commitment to sustainability, encouraging individuals to adopt more environmentally supportive behaviors and a deeper commitment to environmentalism.

This qualitative investigation examined rooftop farming in Turin, Paris, and Rotterdam, focusing on local practices, policies, and stakeholder perceptions of sustainability and social impact. Findings reveal significant differences in governance: Turin's OrtiAlti project faced difficulties due to absent city strategies and policies, while Paris has a moderate number of rooftop farms with recent supportive policies. Rotterdam's Dakakker is a consolidated project, supported by local government through multi-stakeholder participation.

David Anaafo, G. A. Akolgo · · Ghana

A study on urban agriculture in Ghanaian cities found that it faces challenges including difficult access to land and water resources, and a lack of extension services and credit support. Despite these issues, urban agriculture may help reduce flooding impacts, improve water infiltration, and enhance environmental sanitation. The study recommends policy measures to address these challenges.

Lucy Diekmann, Leslie Gray, Gregory A. Baker · Local Environment · United States (California)

This case study in Santa Clara County, California, used interviews and surveys to explore the implications of historic drought for urban agriculture (UA). It found that metropolitan California's decentralized water supply and diverse institutional arrangements create an uneven landscape of water access for UA. This results in geographically and socially differentiated pressures on UA water users to change water-consuming practices, with responses varying due to site-specific sociotechnical arrangements and UA purposes.

This research compared factors leading to community garden initiatives in Porto, Portugal, and Belo Horizonte, Brazil, focusing on the influence of urban planning processes. It found differences in how urban planning in both cities incorporates urban agriculture practices. The connections between urban agriculture and urban planning, facilitated by environmental planning practices, were found to be incipient, hindering planning's goal of catalyzing a sustainable city.

LE Wynne, Dana Cordell, Joanne Chong, Becky L. Jacobs · UTS ePRESS (University of Technology Sydney) · Australia (Sydney)

This report, using Sydney as a case study, examines land-use planning on the urban fringe for peri-urban food production. It finds that for many cities, including Sydney, a large proportion of peri-urban food production has already been lost due to conversion to residential and infrastructure uses. The report reviews various planning responses to address threats to peri-urban agriculture.

Thaís Cristina Schneider, Paulo André Niederle, Myrian Regina Del Vecchio-de Lima · Razón y Palabra · Brazil

This article analyzes urban agriculture from a communication perspective, focusing on how practitioners and non-practitioners understand its critical and alternative role regarding the modern food system. The study of Quinta da Videira in southern Brazil found that while urban agriculture is used to counter conventional food production and associated lifestyles, there are also resistances to integrating agricultural practices into the urban environment.

Charlotte Prové, Joost Dessein, Michiel De Krom · Ghent University Academic Bibliography (Ghent University) · Belgium; Poland

A study evaluating urban agriculture in Belgium and Poland argues that current governance approaches fail to reflect the importance of local context. The authors found that considering city-specific factors is crucial for urban agriculture to reach its full potential. They recommend a broader policymaking strategy that acknowledges benefits beyond food production.

Kyung-chan Min, Jee-young Kim, yong-hoon Son · Institutional Repositories DataBase (IRDB) · South Korea

A study in Gwanak-gu, Seoul, South Korea, investigated 45 spontaneous agricultural lands, primarily around Mt. Gwanak, which often present risks like disaster, pollution, and landscape degradation. Using GIS, satellite images, field surveys, and interviews, the study classified these lands into six types. Three types were well-managed, while three types were in poor condition, indicating governance challenges. The research discusses the causes of these conditions and explores the potential for these lands to become community open spaces.

This study assessed the performance of Caritas-initiated and sponsored community gardens in Chaka ward, Chirumanzu District, Zimbabwe, during and after the sponsors' regime. Data was collected using questionnaires, interviews, and direct observations, and analyzed with descriptive statistics and content analysis. Results showed that the gardens flourished during Caritas's presence but quickly shrank and folded after the NGO's departure, indicating a lack of sustainability.

Gunwon Lee, Yunnam Jeong, Byunghak Min, Seiyong Kim · Journal of the Korea Academia-Industrial cooperation Society · South Korea

This study investigated improving South Korea's Biotope Area Ratio system for urban agriculture vitalization. The research found that the existing Biotope Area Ratio indicators, which only consider soil depth and permeability, have limitations in managing plant growth for urban agriculture. Focusing on daylight conditions as a critical factor, the study concluded that the current Biotope Area Ratio indicators are insufficient for adequately addressing plant growth in urban agriculture.

Tian Lib · Chinese Journal of Tropical Agriculture · China (Hainan)

This paper summarized the status of protected horticulture in Hainan, China, identifying major problems such as a deficiency of special varieties, unsuitable introduced facility types, lack of a non-nuisance production system, and insufficient capacity for resisting natural disasters and environmental control. To achieve sustainable development, the local government needs to strengthen funding and policy support, enhance farmers' awareness of pollution-free production, and improve management techniques.

Da Wang · · China (Beijing)

This study evaluates and analyzes urban agriculture in Beijing by focusing on the relationships among its subsystems and their relative influence. Results show that the comprehensive evaluation index of urban agriculture has risen steadily with a positive trend, but that the comparative advantages of both the population subsystem and the social subsystem have weakened, due to the loss of agricultural labor force and the urban-rural income gap. Meanwhile, the function of the environment and resource subsystems has strengthened, promoting a shift in Beijing's urban agricultural mode from one led by the economic subsystem toward one led jointly by the environment and economic subsystems. Given increasing pressure on environment and resources, the study concludes Beijing needs to build an ecological urban agriculture system and move away from an industrial development approach.
