A spatial analysis and socio-economic survey were conducted on land occupation, land conflicts, and their management in the Funa Valley in Kinshasa. The findings revealed a strong evolution of anthropogenic presence in the valley and identified multiple land conflicts, including illegal sales of parcels by customary chiefs and illegal occupation of agricultural land by non-market gardeners. The management of these conflicts is often referred to the district chief and the justice ministry.

This review examines the application of food sovereignty principles in urban and peri-urban agriculture in Zimbabwe. It notes that despite urban households integrating these practices into their livelihoods, institutional arrangements governing them remain ambivalent. The review concludes that the failure to involve all stakeholders undermines urban and peri-urban agriculture, leading to increased food insecurity and unsustainable practices.

David Ceaser · Agritecture · United States

In this December 7, 2018 article for Agritecture, horticultural consultant David Ceaser reports on the challenges facing agrihood development, using The Cannery in Davis, California (500+ homes, 150 acres, with a 7.4-acre organic farm) as a case study. He notes that residents held unrealistic expectations about how the farm would be run and their role in it, and that poorer-than-expected soil quality required amending with organic matter, delaying farm development. Farm Director Sri Sethuratnam described the aging farmer population and food-production challenges as "a national security issue."

Jana Spilková, Jiří Vágner · Norsk Geografisk Tidsskrift - Norwegian Journal of Geography · Czechia

This study examined the historical context, current spatial patterns, and recent trends of urban food gardens in Czechia using literature review, geographical mapping, and semi-structured interviews in Prague. It found a strong tradition of urban agriculture, with gardens concentrated in major cities and industrial areas. However, uncertainty regarding land tenure and long-term sustainability were identified as major obstacles for the future of allotment and community gardens.

Simone Tappert, Tanja Klöti, Matthias Drilling · Landscape and Urban Planning · Switzerland

A qualitative study conducted in the Swiss cities of Basle, Berne, Geneva, and Zurich analyzed the political negotiation processes of urban gardening within the compact city framework. Findings demonstrated that urban growth strategies, aiming for efficient and resource-saving reorganization of urban space, are discursively rationalizing current transformation processes. This has led to traditional forms of urban gardening being closed down, displaced to less significant locations for urban development plans, or spatially and functionally transformed, while new forms of urban gardening are emerging in inner-city areas.

Since 1990, Aichi Prefecture, Japan, has seen a decrease in agricultural land area and the number of farm households, particularly in Nagoya City and its surrounding municipalities. While the reduction in productive green space and full-time farmers was moderate, engagement in agriculture-related businesses, excluding direct sales, was not extensive. A polarization was observed between municipalities active and inactive in designating productive green spaces, posing a challenge for future land use planning.

Lidia Poniży, Kamila Stachura · Quaestiones Geographicae · Poland (Poznań)

This case study of Poznań, Poland, examines urban spatial policy regarding allotment gardens. It finds that despite their importance as green infrastructure, allotment gardens receive little attention in city plans and policies, and face threats from investment pressure due to an underestimation of their role. The study emphasizes that preserving these gardens relies on local spatial planning.

Marlinde Koopmans, Daniel Keech, Lucie Sovová, Matthew Reed · Moravian Geographical Reports · Europe

This paper analyzed urban agriculture (UA) and place-making in Ghent, Brno, and Bristol, using a spatial lens across three case studies. It revealed that local authorities struggle to find space for UA, leading to its frequent, often temporary, emergence in marginal areas vulnerable to planning changes. The analysis exposed inherent tensions within UA, conceptualized as tensions between abstract space and concrete place narratives. It was suggested that UA, as a collective socio-cultural process, can transform functionally replicable spaces into unique places, contributing to place-making, and urban planning should secure physical spaces and create possibilities for local autonomous governance.

Olalekan John Taiwo · · Nigeria (Lagos)

A study in Lagos State, Nigeria, analyzed the characteristics of urban agriculture and the influence of land use diversity using 300 questionnaires and personal interviews. The research noted the rapid disappearance of urban agricultural sites within built-up areas, framing it within the concept of "survival of the fittest." Results indicated that land use characteristics where urban agriculture is located moderate its size, rental cost, profit, and accessibility to road networks, while having little to no influence on its distance from markets and water sources.

肇 石原, Hajime ISHIHARA · Institutional Repositories DataBase (IRDB) · Japan

Since 1990, the weakening of agricultural management foundations has been observed in urban areas of Nara Prefecture, though the decrease in productive green space and the number of full-time farmers remained at a certain level. Rice cultivation was the main crop in many areas, and engagement in agriculture-related businesses, apart from direct sales, was not extensive. Regarding the designation of productive green spaces, many cities were reluctant during the initial designation following the revised Productive Green Space Act and also during the Heisei mergers, which is identified as a challenge for future land use planning.

Elena Domene Gómez, Francesc Coll, Marta Garcia-Sierra · Dialnet (Universidad de la Rioja) · Spain (Barcelona)

Informal vegetable gardens have proliferated in Barcelona's urban periphery since the 1980s, serving as leisure spaces and food sources, and are a relevant form of agriculture. However, these "unregulated" spaces are not considered in urban and peri-urban agriculture promotion policies. A GIS methodology mapped these gardens in the Barcelona metropolitan area for 2009 and 2015, showing an increase in occupied surface during the recent economic crisis. The study evaluates contradictions leading municipal managers to eliminate or regulate these informal spaces, attributing them partly to the subjectivity of the urban and peri-urban agriculture concept and its supposed multifunctionality.

Yoonah Jang, Sun Jin Jeong, Kyeong Suk Han, Gyung Mee Gim, InChan Choi, Joonyung Heo · The Korean Journal of Community Living Science · South Korea

A study investigated the status of school gardening in 164 elementary schools (39.4% of 416) in Jeollabuk-do, South Korea. The installation and automation of garden facilities, such as greenhouses and tool sheds, were poor. Teachers, who most often operated the gardens, reported difficulty managing them due to a lack of knowledge about sustaining gardens and expressed a need for training programs.

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.

Arguing that analyzing territory across multiple scales requires an analytical framework grounded in the dynamic, repeated interweaving of elements and processes that combine into — and clash as — diverse "territorial fragments," this paper examines urban agriculture as a site where city and countryside, urban and rural, and their diverse practices approach, blend and are sometimes confused with one another. Focusing on horticulturists in the Gramorezinho Community in Natal, Rio Grande do Norte, Brazil, as its case, the study shows that historical and spatial singularities — environmental, socioeconomic and administrative — have produced distinct processes that at times align and at other times contradict one another.

Eva Olsson, Eva Kerselaers, Lone Søderkvist Kristensen, Jørgen Primdahl, Elke Rogge, Anders Wästfelt · Sustainability · Europe

A study focusing on peri-urban land in Gothenburg (Sweden), Copenhagen (Denmark), and Gent (Belgium) analyzed the relationship between peri-urban food production and urban resilience. It found that arable farming has declined in all three areas since 2000 due to urban expansion and recreational land use changes. While policies for farmland preservation exist, strategies for local food production are not expressed in current planning documents, and competing land uses and high dependence on global food systems reduce peri-urban food production and improvements in urban food security.

雷靖, 陈斯钰, 刘煜 · 农村经济与科技 · China (Zhoushan)

This study examines Zhoushan City's "Vegetable Basket" project, which established production bases in urban and rural areas to ensure vegetable supply and stabilize prices. Despite significant achievements, the project is noted to have problems such as incomplete vegetable supply varieties, imperfect infrastructure, low industrialization, and a lack of quality assurance. The study suggests addressing these issues by diversifying product supply, strengthening infrastructure, improving industrialization, and enhancing quality and safety supervision.

Elke Rogge, Eva Kerselaers, Charlotte Prové · · Europe

This study explores opportunities and challenges for peri-urban agriculture, examining envisioning processes in Ghent and Kortrijk, Belgium, initiated by local authorities. Results indicate that pressure on farmland is a key issue in both contexts. Multifunctionality is complex in practice and governance, and successful envisioning processes require clear objectives, defined study areas, policy support, strong leadership, and reliable data.

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.

Christopher Bryant, Ghalia Chahine · Geographical Research · Canada (Montreal)

This 2015 case study from the Montreal Region, Canada, analyzed an action research project initiated in 2008 to reduce the vulnerability of peri-urban agriculture. Despite initiatives since the mid-1960s, significant pressures continue to increase the vulnerability of peri-urban farming, with farmland often removed from agricultural reserves. The project in Senneville involved farmers, non-farm actors, and municipal presentations over three years, aiming to integrate conservation and leisure activities.

宋志军, 刘黎明 · Acta Scientiarum Naturalium Universitatis Sunyatseni · China

Chinese urban agriculture has developed against a backdrop of multifunctionality, urbanization, industrialization, and non-agriculturalization. Since the reform and opening-up, the development of non-agricultural functions has complemented and advanced the broad modernization of urban agriculture, while simultaneously inhibiting, delaying, and destroying narrow modernization. This has led to a "reverse modernization" phenomenon in the spatial pattern of urban agriculture, characterized by changes spatially "opposite" to narrow agricultural modernization. China's current urban agriculture exhibits an overall spatial state of "reverse modernization" with various agricultural forms interspersed.

Achamyeleh Gashu Adam · · Ethiopia

A study assessed the process of built-up property formation in Ethiopia's peri-urban areas. Through analysis of survey results and a review of relevant literature, the study elucidated the processes of peri-urbanization and new property development. It demonstrated that both formal (legal) and informal methods are equally important in converting peri-urban agricultural lands into urban built-up non-agricultural properties. This process creates intense competition for land between agriculture and non-agriculture, leading to the emergence of new property rights and the dissolution of existing traditional rights.

West Africa, Olufunke Cofie · · West Africa

An examination of urban agriculture (UA) development in West Africa reveals that despite its known benefits for food supply and livelihoods, UA is not fully recognized as an important component of urban development. This is due to high land demand from other sectors and perceived health risks by authorities. Policy makers need to address issues to institutionalize UA and integrate it into urban development plans.

N. Claire Napawan · Landscape Journal · United States (San Francisco)

This paper evaluated five case studies of communally-managed urban farms in San Francisco to determine their ability to operate dualistically as areas for food production and public space. Using a case-study methodology, it compared the spatial characteristics of these farms against the spatial criteria for successful public space. The study identified both conflicts and compatibilities in the spatial considerations for both functions.

Rocío Pérez-Campaña · European Planning Studies · Spain

This research analyzed land-use transformations of peri-urban agricultural deltas and vegas in Andalucía, Spain, focusing on medium-sized cities between 1956 and 2007. It also assessed their consideration in regional spatial planning. The findings indicate that these landscapes are changing land use and sometimes disappearing, receiving meagre attention and vague consideration in spatial planning.

徐晶, 吴聪 · 中国土地 · China (Wuhan)

This paper analyzes the practice and problems of "multi-plan integration" in Wuhu Street, Huangpi District, Wuhan City, a rapidly urbanizing area dominated by modern urban agriculture. Wuhu Street faces issues such as the disorderly sprawl of construction land and low land use efficiency. The study proposes targeted policy recommendations based on these findings.
