Where have all the farmers gone? Spatial–temporal transformations of peri-urban agriculture in the Metropolitan Area of Barcelona
2026Johannes Langemeyer, Gabriele Gervasi, Sergi Ventura Caballé, Gara Villalba Méndez · Ecology and Society · Spain (Barcelona)
This study examined the spatial-temporal transformations of peri-urban agriculture in the Metropolitan Area of Barcelona from 2003 to 2015, combining spatial analysis of land use changes with qualitative insights from stakeholder interviews and workshops. Results reveal that the significant decline of peri-urban agriculture is driven by a complex interplay of real-estate speculation, land fragmentation, infrastructure development, evolving land use policies, and ecological pressures from land abandonment and environmental protection. Despite efforts to preserve agricultural spaces, the decline of peri-urban farming remains significant.

2025Javier Rodrigo-Ilarri, Claudia P. Romero-Hernández, Sergio Salazar-Galán, María-Elena Rodrigo-Clavero · Sustainability · Spain (Valencia)
This article analyzes the impact of urban sprawl on the Valencia Plain aquifer system from 1990 to 2018 using the Weighted Environmental Index (WEI). Results show urban surfaces expanded by 70% and rainfed agricultural areas declined by over 59%, leading to a 9.2% reduction in environmental value (WEI decreased from 44.80 to 40.68). These changes threaten ecosystem sustainability and reduce the capacity to deliver ecosystem services.

2024Ricard Segura, Johannes Langemeyer, Alba Badía, Sergi Ventura, Jaime Vila-Traver, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
A study in the Metropolitan Area of Barcelona, Spain, investigated the impacts of peri-urban agricultural expansion on the food-water-climate nexus using urban metabolism and atmospheric-biosphere models across four land-use scenarios. While expansion increased food production and irrigation water requirements, replacing natural non-forested and forest areas for peri-urban agriculture was predicted to reduce net ecosystem productivity by up to 18.5% and total carbon stocks by 3.3%. Irrigated peri-urban agriculture potentially reduced near-surface temperatures by 0.7°C, though reductions in the densest urban areas were minimal.

2024Sabina Rossini Oliva, Rafael López Núñez · Environmental Science and Pollution Research · Spain (Andalusia)
This study evaluated potentially toxic elements (PTEs) in vegetables and topsoils from urban gardens in Seville, Cordoba, Huelva, and a mining area (Riotinto), Spain, comparing them with market and peri-urban samples. Soils in the mining area and cities generally showed higher contamination with As, Cr, Cu, Pb, and Zn compared to other locations. Despite this, all PTE concentrations in vegetables from the studied urban gardens, including those from As-contaminated soils, were below health-based guidance values and market levels (except lettuce), and human health risk assessments indicated safe consumption.

2024Elliot Buckminster, Charlotte Breckenridge, Thomas Sedgwick · International Journal of Research in Agronomy · United Kingdom
This research quantified soil-to-plant transfer factors for six heavy metals (Cd, Pb, Zn, Cu, Ni, Cr) in lettuce, spinach, and carrot across 20 peri-urban agricultural sites in Berkshire, UK, from 2021-2022. Cadmium exhibited the highest mean transfer factor (0.31), and at 4 of 20 sites, cadmium concentrations in lettuce exceeded the EU maximum limit of 0.20 mg/kg fresh weight. Soil pH was a strong predictor for Cd and Zn transfer factors, with TFs increasing below pH 6.0.

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.

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.

2023Alioune Badara Dabo · Norois · France (Île-de-France)
This article analyzes how the public land tenure system, introduced in the 2018 "Agricultural Pact" in the Île-de-France region, articulates with local farming systems. Based on a qualitative survey conducted in the Green Belt area, the findings reveal that this land tenure system does not fully align with the strategies of farmers, particularly young people outside family farming who wish to establish themselves in agriculture, as they do not necessarily seek land ownership.

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.

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.

2022Giulia Giacchè, Véronique Saint-Gès, Yoann Durrieu, Mélanie Collé, Christine Aubry · Territoire en mouvement · France
A multi-phase method, METH-EXPAU®, is proposed for defining urban agriculture (UA) projects, aiming to help landowners select appropriate UA forms based on territorial characteristics. Applied to three case studies in France—Montrouge, a priority district in Lille, and a new district in Bordeaux—the method revealed its potential and shortcomings. It demonstrated how structural, technical, and social characteristics of spaces and agents can rule out certain UA forms that do not correspond to the territory's current needs.

2020Esther Sanyé‐Mengual, Kathrin Specht, Jan Vávra, Martina Artmann, Francesco Orsini, Giorgio Gianquinto · Sustainability · Italy (Bologna)
This study compared perceptions of urban agriculture (UA) ecosystem services (ESs) among different societal groups in Bologna, Italy, namely UA project leaders, stakeholders, and the general public, with 406 individuals evaluating 25 ESs via a standardized Likert-scale survey. Statistical analysis indicated that the general public and UA stakeholders agreed on the high relevance of socio-cultural ESs, while provisioning ESs were considered less significant. This study reveals a lower perception of provisioning ESs from urban agriculture.

A study assessed 16 trace elements and 33 organic microcontaminants in lettuce, tomato, cauliflower, and broad beans from peri-urban farms near Barcelona, Spain, and a rural site. Concentrations ranged from non-detectable to 17.4 mg/kg for trace elements and non-detectable to 256 μg/kg for organic microcontaminants, with tomatoes showing the highest levels. Risk assessment indicated a low human health risk from consuming these vegetables in the peri-urban area, comparable to the rural site.
Contamination & food safetyHealthPeri-urban agriculturel’Horta De València: Past and present dynamics in landscape change and planning
2019Carme 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.

2017HENKE Roberto, VANNI Francesco · Zenodo (CERN European Organization for Nuclear Research) · Italy
This 2017 article analyzed the role of peri-urban agriculture in Italy through a comparative study of seven metropolitan areas, using micro-data from the sixth Italian agriculture census. It identified six typologies of market-oriented farms. The study found that a significant share of farms in Italian urban poles are passively absorbed by urban expansion, indicating a challenge to their economic viability. However, the most reactive farms are diversifying and supplying social and economic services.

2017Annalisa Lodigiani · · Europe
This research addresses the ineffective governance of peri-urban agricultural territory in Europe, noting that spatial planning lacks the tools to guide agricultural sector forces influencing landscape transformation. Public action, through agricultural and rural development policies, significantly transforms the environment and territory but does not directly target space. The study finds that the separation between spatial planning and rural development policy creates ineffectiveness and stalemates in governing peri-urban agricultural land, concluding that integration of these two fields is required.

2016Eva 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.
