Published 5 April 2026 and updated 14 June 2026. Full cost recovery means funders covering not only a project's direct costs but its proportional share of overheads — rent, finance, IT, HR and chief-executive time. The article works through an example where two of ten staff (20 per cent of capacity) deliver a project, so £28,000 of £140,000 in annual overheads is added to £85,000 of direct costs for a £113,000 budget, and notes that overhead rates of 15–25 per cent are common sector guidance. It argues that accepting grants below true cost is a structural funding problem rather than a budgeting error, with consequences including staff burnout and governance risk, and notes that charity staff earn roughly 7 per cent less per hour than equivalent roles elsewhere in the economy.

At the Christchurch College of Food Technology in New Zealand, researchers compared five growing systems -- rooftop container, raised bed, peri-urban orchard, rural orchard (reference), and heated greenhouse -- for avocado (Persea americana) cv. 'Hass' under simulated Bavarian Plateau conditions, using a randomized complete block design with four replications over three years (2020-2022). The rural orchard yielded highest at 22.3 kg per tree, peri-urban raised beds achieved 18.7 kg per tree using 56% less land, and rooftop containers (200 L pots) produced only 6.8 kg per tree, confirming that container culture is viable but yield-limited; rooftop systems had the lowest weed pressure, peri-urban orchards supported the richest arthropod biodiversity, and ISSR molecular markers confirmed genetic uniformity among grafted plants across systems, ruling out somaclonal variation as a source of the yield differences.

This study investigated the impact of Community Supported Agriculture (CSA) structures on farm resilience among CSA farmers in Germany. A mixed methodology was applied, combining a case study with one CSA farmer and a survey of CSA farmers across Germany. The findings indicated that CSA provides mechanisms for improving farm resilience through increased income security, risk protection, market independence, and satisfaction. CSA farmers demonstrated a high level of perceived resilience compared to non-CSA farmers.

Anna M. Roodhof · Journal of Agriculture Food Systems and Community Development · Netherlands

To map and analyze food forestry (FF) in the Netherlands, a survey of 109 participants and interviews with five experts were conducted, identifying 231 food forests established since 2017. The survey data indicates that while FF initiatives are diverse in goals, few focus on profitability. Practitioners are largely homogeneous, consisting of university-educated individuals aged 40 to 60.

Alberto 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.

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.

Ambrogio Zanzi, Valentina Vaglia, Roberto Spigarolo, Stefano Bocchi · Land · Italy (Milan)

This study assessed the sustainability of eight agri-food start-ups in a peri-urban area of Milan, Italy, using the FAO's Sustainability Assessment of Food and Agriculture systems (SAFA) framework. The application of SAFA indicators revealed positive aspects but also some limitations typical of unstructured enterprises.

This article analyzes a charity-led community gardening project in a disadvantaged northern English community, which operated for three years with external funding. While it successfully engaged marginalized people, leading to increased skills, confidence, reduced isolation, and improved wellbeing, the project faced significant challenges requiring professional management. Crucially, after the funding ended, the community garden's future was fragile, and the long-term sustainability of outcomes for marginalized participants was vulnerable due to economic viability issues.

Paul D. Jensen, Caroline Orfila · Food Security · United Kingdom

This case study used publicly available data to spatially analyze the urban food system of Leeds, UK, assessing its food security and resilience. The study found that while Leeds has a significant food production and provision system, it is not food secure in terms of providing sufficient energy or macronutrients, nor does it function equitably for all residents. Improving the system, including through urban farming, would require high investment, multi-sector cooperation, and strong governance.

Ágnes Gagyi, Csaba Jelinek, Zsuzsanna Pósfai, András Vígvári · · Europe

This chapter examines the 2000s housing financialization wave in Hungary, analysing financial over-inclusion and exclusion -- alternating dynamics of reaping gains and externalizing costs. It shows that "intermediate" rural-urban transitional zones are prime areas for high-risk mortgage lending while also containing spaces excluded from institutionalized housing finance, using as its case study an allotment garden where households combine formal jobs and mortgage repayment with informal dwelling to reduce housing costs, arguing that such informal reproductive solutions function as a resource for capital accumulation through inclusion and exclusion.

Tezcan Mert-Cakal, Mara Miele · Agriculture and Human Values · United Kingdom (Wales)

This article examines Community Supported Agriculture (CSA) projects in Wales as social innovation, exploring their emergence, innovative role, and transformative potential. Based on qualitative data from four different CSA case studies in Wales, the research showed that Welsh CSA cases play distinctive roles in the social economy, satisfying needs for ecologically sound and ethically produced food and empowering individuals at a micro level. However, the paper argues that for CSA initiatives to become 'workable utopias', they need to overcome barriers preventing replication, participation in macro-level policies, and scaling up, particularly concerning economic sustainability and resilience on a small scale.

Will Thompson · Plinth · United Kingdom

Published 12 June 2019, this piece estimates that UK charities spend around 15.8 million hours a year on grant monitoring reports, roughly £204 million in staff time. It assumes an average of 40 hours per grant, about 391,280 grants distributed per year and an average grant of around £50,000. Charities with at least one full-time-equivalent member of staff typically juggle five to ten different funders, each asking for similar information in different formats at different times, so the administrative load accumulates without producing learning. The estimate draws on interviews with ten people at small and medium charities reporting to six local authorities and more than fifty funders.

Károly Kacz, Ádám Varga · Annals of the Polish Association of Agricultural and Agribusiness Economists · Europe

A survey in the Western Transdanubia region investigated major problems in Community Supported Agriculture (CSA) within short food supply chains, involving farmer organizations and consumers. The analysis identified the insufficient market power of CSA organizations as the most influential factor. This finding suggests a significant constraint on the effectiveness of CSA models in the region.

Pascale Scheromm, Christophe‐Toussaint Soulard · Geographical Research · France

This paper provides a spatial analysis of agriculture in three mid-sized French cities, focusing on professional farms. It confirms the existence of significant agricultural spaces within cities and the persistence of field-based, market-oriented agriculture. Key determinants in the observed dynamics include the cities' geographies, the impact of land speculation and urbanization on farmers, and the resistance and adaptation processes implemented by some farmers.

HENKE 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.

Nerea Morán Alonso, Ícaro Obeso Muñiz, Agustín Hernández Aja, Felipe Fernández García · Moravian Geographical Reports · Spain

This paper analyzed the evolution of peri-urban agriculture in Spain's Madrid and Oviedo metropolitan areas to identify revitalization opportunities. Using aerial images and cartographic bases, the study found that peri-urban agriculture has suffered from urban occupation and internal changes in crops and agricultural uses, experiencing a process of decline. Innovative initiatives are explored as potential revitalization opportunities.

Stephanie Stephanie Kartika Lestari · · Europe

A case study of two urban farming organizations in the Netherlands developed a set of indicators to assess factors hampering the diffusion of radical innovation. Urban farming is characterized here as a radical innovation aiming for fresh and sustainable food supply in urban areas that has yet to achieve large-scale diffusion, and the study proposes a non-static conceptual model that lets commercial firms rationally assess barriers to diffusion and revisit their niche strategies as internal and external conditions change.

Amandine Joly · · France

This study characterized and strategically analyzed urban agriculture for the IETI external planning and environment consulting firm in Île-de-France, France. The analysis aimed to help IETI position itself commercially in urban agriculture, identifying both the benefits and the obstacles the firm might encounter. The study also briefly discussed the various scales of urban agriculture's integration into the territory and its advantages for the consulting firm.

Oliver Moore, Olive McCarthy, Noreen Byrne, Michael Ward · Journal of Agriculture Food Systems and Community Development · Europe

This paper examines one of the earliest and most prominent community supported agriculture (CSA) initiatives in Ireland, focusing on its organizational restructuring under productivity pressure. CSA is built on sharing risk and reward, and some uncertainty is treated as acceptable, but in this case the realized risk of insufficient produce, once pushed to its limits, became in fact unacceptable to members. The process by which this member-owned and member-operated CSA critically self-assessed and restructured after this shortfall is termed "reflexive resilience" — a description of an initiative that had to acknowledge a real produce shortfall and rebuild, not merely one that anticipated shocks in the abstract.

Michela Felicetti · Advanced engineering forum · Italy

A paper examining whether the food hub concept can be applied to the Piana di Sibari area of Calabria, Italy, designated a Quality Agrifood District (DAQ) under regional law. After identifying features of the food hub concept within the area's largest cooperative, the paper argues that this arrangement represents an opportunity for small farmers to access conventional food supply chains from which they would otherwise be excluded. It frames food hubs as a hybrid of alternative and conventional food networks and, notably, as a way to address the economic viability problem faced by local food initiatives such as community-supported agriculture (CSA)—that is, the paper's premise is that CSA-type local food initiatives struggle to be economically viable on their own.

A long-term study in southeastern France examined the development of Community Supported Agriculture (CSA) as an alternative marketing system for fruits and vegetables. The study found that the non-market dimension of CSA appears to have disappeared over time, from its initial form to current basket systems. This change is attributed to the diversification of farmers' sociological profiles and the transformation of marketing conditions for organic local products.

Silvio Caputo · Kent Academic Repository (University of Kent) · United Kingdom

This paper argues for a new role for urban agriculture in developed countries, focusing on environmental, social, and economic benefits. While urban agriculture can contribute to a low-carbon society and food access, it is not currently part of UK government strategies for food security. For urban agriculture to achieve its potential, it needs to become economically viable, requiring research into highly productive methods and business models utilizing local urban resources.

Lucette Laurens · Journal for Geography · France

This inquiry examines peri-urban agricultural spaces in Languedoc-Roussillon and the Montpellier agglomeration, France, which are characterized by a decline in agricultural activities and abandonment. These spaces are confronted with new, uncertain, and innovative dynamics, appearing as multifunctional spaces that need to be re-invented. The study highlights the paradox of these areas caught between appropriation for different uses and agricultural decline.

N. Bertrand, Nicole Rousier · HAL (Le Centre pour la Communication Scientifique Directe) · France (Grenoble)

In the Grenoble urban region, agriculture holds relatively minor economic importance despite the region's strong technological development. However, the region's 2000 master plan assigned an essential role to farming. Peri-urban agriculture is a key issue in planning policies, engaging local officials, planners, and farming community representatives, but its economic weight remains low.

E. F. Schumacher · Blond & Briggs · United Kingdom

E.F. Schumacher's 1973 book challenges the mainstream "bigger is better" economic ethos, advocating small, "appropriate" technologies as an alternative. Its four parts cover the modern economy, resources, the developing world, and organization/ownership; in 1995 the Times Literary Supplement named it one of the 100 most influential books since World War II.
