A qualitative sociological analysis examined a policy tool used by public landowners in peri-urban Milan, Italy, who introduced new lease agreements transferring the maintenance costs of built rural heritage to tenants, aiming to avoid degradation and add value to unused buildings. Analyzing the tool through the lens of social justice and its impact on quality of life, the study found that the same policy tool produces very different outcomes for landscape preservation and quality of life depending on the implementation strategy used, and on the elements of social justice considered along with contextual and individual characteristics.

This paper investigates metropolitan-level strategic planning documents in Sydney, Australia, using a Foucauldian governmentality approach, to understand how they relate to peri-urban agriculture. The analysis reveals that prevailing rationalities, including the global city, compact city, and sustainability agenda, frame the urbanization of peri-urban agricultural lands as necessary and inevitable. Consequently, peri-urban areas are not considered to have unique planning needs but are instead imagined as latent spaces for future housing and job development, integrating agriculture only when it aligns with the 'global city' narrative.

This paper investigates urban agriculture (UA) in South Africa as a citizen-led urban greening strategy, reviewing case studies and the national policy framework. Key limitations include many UA initiatives not being self-sustaining or fully citizen-driven, a cultural stigma, limited national support due to the absence of a dedicated UA policy, and South African spatial planners' limited knowledge of UA. These issues hinder the broader implementation of UA.

In the Bonearense region, urban expansion is encroaching on fertile plains, impacting territorial characteristics. While urban and peri-urban agriculture contributes to food sustenance for the AMBA population, it has not been sufficiently recognized for green area recovery, organic waste recycling, and wastewater management. Regional authorities have begun to acknowledge urban agriculture's role in combating urban poverty, but local economic development faces challenges in mediating food security and recreational services amidst pressures from urban real estate and agro-industrial production.

Ulrich Häpke · sub\urban zeitschrift für kritische stadtforschung · Germany (Ruhrgebiet)

While statistical data demonstrates the significance of urban agriculture in German cities and metropolitan areas, urban agriculture faces the problem of constant land loss despite its proximity to consumers. The example of the Ruhrgebiet highlights challenges such as land loss and high proportions of leased land, indicating governance issues faced by urban agriculture.

Sileshi Azagew, Hailu Worku · ENVIRONMENTAL SYSTEMS RESEARCH · Ethiopia (Addis-Ababa)

This study assessed the status, accessibility, and constraints of urban green infrastructure (UGI) in Addis Ababa, Ethiopia. It revealed that UGI land use decreased by 9.2% from 2003 to 2016, with urban agriculture declining by 11.9%. City residents lack sufficient recreational UGI, with park per capita at a very small 0.37 m² compared to Ethiopian standards of 15 m², and over 90% of the population lacking access to existing parks within walking distance. Major constraints identified include weak implementation of development plans, density, built-up area expansion, and lack of priority for UGI development.

Sarah Taylor Lovell · Urban Agriculture & Regional Food Systems · Global

Despite increasing awareness and proposals for urban agriculture implementation, broad integration into the urban environment has not yet been observed. In most cities, the level of food production has not expanded significantly enough to impact the supply of vegetables, fruits, or other products. Key barriers limiting widespread adoption of urban agriculture include land access, zoning and tax policies, risks of soil and air contaminants, and urban forestry plans neglecting food security.

Anna Shortly, Thembela Kepe · Forests Trees and Livelihoods · Canada (Toronto)

This paper explores the opportunities and challenges of incorporating foraging practices into parks planning and management in Toronto, Canada, where foraging is often not permitted in urban parks. The study, based on a scan of practices and interviews, concludes that urban parkland managers should establish dedicated spaces like community orchards to safely and sustainably accommodate foraging, acknowledging current restrictions.

Amsalu Woldie Yalew · Regional Economic Development Research · Ethiopia

This paper provides an overview of urban agriculture in Ethiopia, synthesizing existing evidence on its role in the overall agricultural sector, urban economy, and urban employment, based on official reports and statistical surveys. Despite scant evidence, urban agriculture shows considerable contributions. However, the review reveals existing gaps in institutional and policy support for urban agriculture.

Mr. Isaiah ACQUAH, Dr.Sc. Joseph Ato FORSON, Dr.Sc. Theresa Yaaba BAAH-ENNUMH · DOAJ (DOAJ: Directory of Open Access Journals) · Ghana

This qualitative exploratory study in Accra Metropolitan Assembly, Ghana, investigated the effect of urban growth and concretization on urban farming households' livelihoods and food security. The study, using interviews and spatial imagery, found that urban farms face challenges due to inadequate land use planning and support, leading to a loss of farmlands. Significant challenges identified include limited farming space, limited resources, continuous increase in buildings, and inadequate education for urban farmers.

Nadine Appelhans, Sabine Baumgart · · Morocco

An analysis of documents related to planning and agriculture and interviews with experts in Morocco indicated that urban and rural issues were treated as separate areas. Urban development affects daily travel distances as urban expansion changes distances between cultivated land and dwelling places. Data from Morocco show a lack of serious support for urban agriculture and animal husbandry in expanding urban agglomerations.

Nicolás A. Mari, Nicolás A. Mari, Beatriz Giobellina, Beatriz Giobellina, Alejandro Benítez, Alejandro Benítez, Victoria Marinelli, Victoria Marinelli, Victoria Marinelli · Journal of Agronomy Research · Argentina (Córdoba)

A study mapped and quantified urban growth and land use in Córdoba, Argentina's Green Belt. Using remote sensing and GIS, it evaluated urban growth between 1974 and 2014 and land use in peri-urban and rural areas in 2015. The study revealed a 46.5% urban area growth over nearly 40 years, alongside an increase in farm plot size, indicating land ownership concentration and a reduced number of producers. This transformation highlights a conflict between peri-urban horticulture, industrial agriculture, and urban development.

This article describes the obstacles to implementing public policy for family agriculture in urban areas of Brazil. Representations associated with rural-agricultural concepts have shaped the classification criteria of rural technical assistance technicians, limiting the policy's application in urban settings. Social movements in Rio de Janeiro highlighted the lack of access for urban family farmers to agrarian policies, leading to the recognition of urban family agriculture as a public problem.

I Gusti Agung Adi Wiraguna, Ngakan Putu Sueca, I Made Adhika · RUANG-SPACE Jurnal Lingkungan Binaan (Space Journal of the Built Environment) · Indonesia (Denpasar)

This mixed-method study in Denpasar, Indonesia, investigated factors driving the conversion of urban agricultural land, primarily rice paddy fields. Despite a local government requirement for 30% urban open space, statistical data showed an average annual decrease of 31.86 hectares of farming land, from 2,632 hectares in 2010 to 2,409 hectares in 2017. The study revealed that various parties, including the government, community, private sector, and social institutions, play important roles in directing this land conversion.

Peter R. W. Gerritsen, Víctor Sanchez Bernal, Georgina Torres Rodríguez · Brazilian Journal of Development · Mexico

This study analyzed food security in two medium-sized cities in Western Mexico using secondary data and field research. It found that while these highly globalized cities had a low degree of food security, extensive domestic backyard agricultural activities significantly raised family-level food security. A critical finding is that this potential for urban food security is not valued by governmental institutions.

Rikawanto Eko Muljawan · Prosiding Konferensi Nasional Pengabdian Kepada Masyarakat dan Corporate Social Responsibility (PKM-CSR) · Indonesia (Surabaya)

In East Java, Indonesia, rapid infrastructure development leads to approximately 100 hectares of agricultural land being converted annually, reducing food supply. In Surabaya, 2000 hectares are controlled by developers, with some loaned for farming, and the local government supports urban farming for 624 households on 400 hectares. The abstract suggests that developers, who benefit from extensive land conversion, should contribute to agricultural resource improvement through Corporate Social Responsibility funds for agro eco-technology programs.

Carme Melo Escrihuela · International Journal of Sustainable Development and Planning · Spain (Valencia)

The evolution in the preservation, management, and planning of l'Horta de València, a historical Mediterranean huerta in Valencia, Spain, was assessed. It is argued that negative changes and impacts in l'Horta are not simply the outcome of global dynamics but result from the region's planning trajectory and landscape management approach. This approach has been shaped by a lack of territorial and supra-municipal perspective and the primacy of culture, identity, and heritage aspects over the landscape's productive dimension.

Global urbanization and food production are in direct competition for land. Displacing crop production from urban and peri-urban land due to soil quality issues will demand a substantially larger proportion of the Earth’s terrestrial land surface than the area lost to urban encroachment. This risks triggering distancing effects, unfair social-ecological teleconnections, and amplifying effects within the Earth System, potentially leading to food riots in cities of the Global South. The paper identifies multi-level leverage points, specifically an advisory global policy aligned with regional policies enabling robust common property rights for bottom-up actors in urban and peri-urban agriculture (UPA), to navigate urban expansion away from fertile croplands.

Sofia Nikolaidou · Manchester University Press eBooks · Europe

This chapter examines new forms of urban gardening, often involving informal and temporary reuse of vacant land, and their impact on urban green space governance and planning practices. Using examples from Greece and Switzerland, it highlights differences and similarities in practices, social and institutional contexts, and collaborative governance patterns. The study calls attention to the critical role of the temporary nature of these initiatives, which affects new configurations of urban green areas and public space, and related planning practices.

A Noussia · Research Open (London South Bank University) · Brazil

This paper discusses urban agriculture on city peripheries within a scenario of urban expansion, focusing on the Guaratiba neighborhood in Rio de Janeiro. It argues that the city's urban expansion process does not invest in the inclusion of urban agriculture activities within the area's socio-environmental dynamics.

Anna Trembecka, Anita Kwartnik-Pruc · Sustainability · Poland

This study analyzed data on the number and area of allotment gardens, their distribution across Poland, and the process of regulating the legal status of land occupied by allotment gardens. The research identified the number and area of family allotment gardens in Poland, along with the range and types of claims against them. The study found that land occupied by family allotment gardens requires protection and legal status regulation, which is difficult due to various entities submitting claims to these areas because of their attractive urban locations.

Suranga Wadduwage · Journal of Land Use Science · Australia (Adelaide)

A multi-criteria spatially-explicit study in the Adelaide metropolitan area, Australia, investigated agricultural land vulnerability to urban sprawl under opposing policy directions. The study showed higher agricultural land vulnerabilities in “Business-As-Usual” and “Accelerated Economic Development” scenarios, extending into rural areas with a leap-frog effect. This confirms the need to sacrifice farmland uses to maintain land supply for urban development under these conditions.

Marttem Costa de Santana, Everardo de Sousa Luz, Maurício Ribeiro da Silva, Maclóvia Corrêa da Silva, Eloy Fassi Casagrande · Sociedade e Território · Brazil

This qualitative field study in two cities in Piauí, Brazil, evaluated whether working conditions of urban and peri-urban agricultural producers contribute to food production. It concluded that public authorities' participation is necessary to address failures in the small-scale agricultural production system and improve working conditions for urban horticulturists.

Paloma Gonzalez de Linares · International Journal of Design & Nature and Ecodynamics · Hungary (Budapest)

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.

Sécou Omar Diédhiou, Oumar Sy, Christine Margétic · Espace populations sociétés · Senegal (Ziguinchor)

A study in Ziguinchor, Senegal, surveyed 248 farmers and 130 vegetable vendors in 2016 and 2017 to examine the role of urban agriculture. Urban expansion has led to shrinking agricultural land and land-use conflicts, while increasing food demand. Women play a central role from production to commercialization, farming in multiple locations for self-consumption and income, but the sustainability of these practices requires integration into proactive urban development policies.
