2024Alberto Matarán-Ruiz, David Fanfani, Josefa Sánchez Contreras, Miguel Ángel Escalona Aguilar · · Central America; Europe
This chapter examines bioregional food systems and territorialization processes in peri-urban agricultural areas, using three case studies from Central America and Europe. It notes that the historical co-evolutionary relationship between cities and surrounding farmlands weakened in modernity due to the global capitalist market, which reduced food to a commodity. The study highlights current problems while exploring how inherited relationships are being revived to adapt urban bioregions to climate emergency and resource scarcity.

2023Setyardi Pratika Mulya, Heru Purboyo Hidayat Putro, Delik Hudalah · Geography and sustainability · Global
This 2023 global systematic literature review examined peri-urban agriculture (PUA) as an ecosystem service, focusing on urbanization pressures and governance. The review found that PUA is crucial for urban areas in terms of food supply, ecology, biodiversity preservation, disaster mitigation, and recreation. However, massive urban expansion is a primary cause of PUA loss, and sociocultural biases have led to institutional constraints on peri-urban management within existing political and regulatory frameworks.

2023Pengyao Li, Feinan Lyu, Yuan Zhou, Zhenrong Yu · Ecological Indicators · China (Beijing)
A study in Beijing, China, surveyed ground spiders and carabids in 12 plantation forests and nearby arable lands to assess the impact of afforestation on biodiversity. Intensive afforestation on arable lands did not increase local ground arthropod diversity. Ground arthropod abundance and species richness in plantation forests were significantly lower than in arable lands when surrounding arable land cover was relatively high, and overall landscape-scale diversity was not improved.

2023Wojciech Sroka, Piotr Sulewski, Jarosław Mikołajczyk, Karol Król · Agriculture · Poland
This study, based on a survey of economically successful peri-urban farms in Poland, identified success factors and major barriers to their development. The research shows a considerable convergence in business solutions in recent years, particularly in customer relationships and channels. According to respondents, the success of peri-urban farms is primarily determined by three groups of factors: motivation, diligence, and creativity; high quality of products and services; and cultivating deep bonds with customers. While farm managers indicated relatively few internal problems, urban pressure was considered the most significant external barrier to development.

2023Benjamin Felix Richardson · · New Zealand (Auckland)
Auckland's urban sprawl threatens to significantly raise the price of fresh fruits and vegetables across the country, worsening chronic food security issues. Food production has become detached from the food security and food sovereignty of Aotearoa's people. The severity of this issue is driving calls for reform, and a conflict exists between humanity's agricultural subsistence and the destabilizing demands of financial extraction, where crucial productive hubs can be lost permanently.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.

2022Fa Likitswat, Alisa Sahavacharin · Journal of Architectural/Planning Research and Studies (JARS) · Thailand (Bangkok)
This research analyzed landscape transformations, specifically agricultural landscape structures and functions, in eight selected sites in the urban fringe of Bangkok from 1952 to 2018. The study found that the significant loss of agricultural landscape in Bangkok's peri-urban areas resulted in the loss of seasonal water retention areas, productive landscapes, and urban wildlife habitats. It concludes there is a research gap regarding the lack of policies and practices to promote ecosystem services linked to preserving peri-urban agriculture in Bangkok.

2022Imen Bendjemila, Salah Chaouche · DOAJ (DOAJ: Directory of Open Access Journals) · Algeria
Urban sprawl in N'Gaous, Algeria, expanded its land area by over ten times (from 33.7 to 379.7 hectares) and its population by over six times (from 4,887 to 33,515 persons) over 60 years. This rapid growth creates significant issues, particularly for peri-urban orchards, which are the primary economic activity. The study used an analytical approach with Geographic Information Systems to assess the agronomic potential of soils and quantify agricultural land consumed by construction, aiming to achieve an optimal agri-urban balance rather than merely avoiding urban expansion.

2022Rosangela Hespanhol, Antônio Nivaldo Hespanhol · Revista de Tecnologia & Gestão Sustentável · Brazil
A case study of urban agriculture in Álvares Machado, Brazil, identified challenges including difficulties in accessing land and water for irrigation, the absence of official technical assistance services, and a lack of public policies at national, state, and municipal levels. Despite these difficulties, urban farmers are responsible for a significant portion of leafy greens and legumes production, establishing direct relationships between producers and consumers through markets and street stalls.

2022Asa Roast · International Journal of Urban and Regional Research · China
An ethnographic study in Chongqing, Southwest China, examined informal peri-urban agriculture on undeveloped land created by state-led expansion since the early 2000s. This "empty land" is informally used by displaced peasants and migrant workers for agriculture. The study reveals that these spaces are ambiguously positioned outside urban governance and are under threat of rapid enclosure within urban accumulation regimes.

This study in Fez, Morocco, compared bacteriological and parasitological contamination in urban, peri-urban, and rural irrigation waters, and their transfer to soil and crops (cardoon and eggplant). Investigated microorganisms included total and thermotolerant coliforms, helminth eggs, Salmonella, and cholera vibrio. Results revealed contamination exceeding national and international standards for both types of coliforms in treated wastewater (TWW), wastewater (WW), Oued Fez water, and upstream well water in both winter and summer. This fecal contamination was found in soils and crops irrigated by urban and peri-urban water. Helminth eggs and cholera vibrio were also present in these waters, soils, and crops, with Salmonella detected in TWW in summer. Only the plot irrigated with Oued Bitit water in the rural zone met standards across all three levels of irrigated water, soil, and plants, and in both periods.

2022Angelica Mendoza Beltrán, Roc Padró, María José La Rota-Aguilera, Joan Marull, Matthew J. Eckelman, Jacob Cirera, Annalisa Giocoli, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study implemented an attributional, regionalized, cradle-to-gate life cycle assessment (LCA) to assess 14 environmental impacts of peri-urban agriculture (peri-UA) in the Metropolitan Area of Barcelona (AMB). It found that vegetables and greenhouses, the prevalent peri-UA land uses, had the largest assessed impacts among all peri-UA land uses. European NPK mineral fertilizer production to cover nitrogen demand for these crops drives all impacts. For fruit crops, on-site nitrogen emissions drive marine eutrophication impacts, and for irrigated herbaceous crops, phosphate runoff drives freshwater eutrophication impacts.

2022Pablo Torres Lima, Kristen Conway-Gómez, Karla Almanza-Rodríguez · Frontiers in Sustainable Cities · Mexico (Mexico City)
This study examined local community involvement in governance processes in Milpa Alta, a peri-urban agricultural area of Mexico City, using surveys, interviews, and participatory workshops. It found that Milpa Alta lacks integral adaptive capacity to address urban pressures, environmental deterioration, and agricultural dynamics. Limited participation, low local organizational levels, and distrust of government institutions hinder effective governance, indicating that a "local is not enough" approach is insufficient for adaptive governance in this peri-urban context.
