A Wikipedia article on the Huerta de Valencia, the historic agricultural belt surrounding the city of Valencia. Origins trace to Roman settlement, but the irrigation infrastructure that shaped the current landscape was developed during the Al-Andalus (Islamic) period. Nine major irrigation canals (acequias), including Quart and Mestalla, are governed by the Tribunal de las Aguas de Valencia, inscribed on UNESCO's Intangible Cultural Heritage list.

This paper presented several circular economy practices integrating circular strategies at an urban scale, focusing on the Centocelle district in Rome, Italy. Through the employment of smart solutions and a collaborative process involving citizens, circular economy urban practices such as community gardens, co-workings, local and km0 production systems, and recycling centers were identified. These practices achieved urban transformation in terms of regeneration, sharing economy experiences, resource optimization, and closed-loop systems, positively and actively influencing the urban community in supporting the transition towards circular economy models.

A study analyzed the distribution of local products through short food supply chains (SFSCs) in Hungary, focusing on farmer markets and Community Supported Agriculture systems, using data from multiple databases. Both traditional and neo-traditional SFSC forms were found to be viable in Hungary, but as in other Central and Eastern European countries, traditional SFSC types—particularly local farmer markets—remain dominant in numbers; the study concludes that forming and supporting neo-traditional organizations is useful for exploiting the potential of short supply chains.

Paul de Graaf · Eetbaar Rotterdam · Netherlands

This Eetbaar Rotterdam retrospective (author Paul de Graaf, published 30 April 2019) on Rotterdam urban farming project Uit Je Eigen Stad (UJES) states that UJES was declared bankrupt on 13 November 2018, bringing a definitive end after 6 years to one of the most notable urban agriculture experiments in Rotterdam. It opened with a festive celebration in September 2012, but the idea's seed dates to 2006, when Bas de Groot's graduation plan at the Warmonderhof school (for a care garden) went unrealized and later grew within the urban-agriculture expertise group Eetbaar Rotterdam. The site was the Marconistrip, designated a 'freezone' by the municipality; financing came from housing corporation Havensteder (investing in buildings, expecting return via rent), high-interest loans from Stichting DOEN and Rabobank, small crowdfunded contributions, and municipal officials' time (under alderwoman Van Huffelen) securing permits. The plan was to build a farm and recoup investments over 10 years, but the article describes this as a difficult effort in which urban-farming ideals clashed with profit-driven activity.

VIPARIS · VIPARIS · France

Official news article from venue operator VIPARIS describing Nature Urbaine, a 14,000 m² urban rooftop farm atop Paris Expo Porte de Versailles. It produces about 200 kg of fruit and vegetables per day, promotes short-circuit local distribution, and reuses urban resources such as unused space, organic waste, and waste heat. Open to visitors on Monday and Saturday mornings.

RESET · RESET · France

Article from the German web media outlet RESET describing La Caverne, an underground farming project by startup Cycloponics in a disused 3,500 m² Paris car park. It grows mushrooms, endives, and microgreens, with yields ranging from 2 kg for herbs up to 300 kg for endives depending on the crop. The project uses energy-efficient LED-lit hydroponics, won the City of Paris's 'Parisculteurs' competition, and plans deliveries by electric bike and fully electric vehicles.

Malin Gustafsson, Matilda Olsson · · Netherlands (Schiedam)

This thesis focuses on a design proposal for a multifunctional foodscape in a peri-urban area on the city edge of Schiedam, in the Metropolitan Region of Rotterdam-The Hague, Netherlands. The proposal includes food production, education, and recreation, aiming to transform peri-urban areas into multifunctional zones and exemplify their role as transition zones between urban and rural landscapes. An empirical pre-study was conducted, focusing on urban farming in Rotterdam, dairy farming in Midden-Delfland, and greenhouse horticulture in Westland.

Richard Almenius · · United Kingdom

A 2016 urban planning thesis on London, United Kingdom. It states that London imports 80 percent of its food, much of it from abroad over long distances ("food miles"), raising sustainability concerns and contributing to road freight congestion and pollution in the inner city. The thesis proposes redeveloping the brownfield land of Greenwich Peninsula in south-east London — near the Millennium Dome, the Thames, and underground access — by combining rooftop and courtyard urban farming with large-scale food production in a converted former industrial building, presented as a pilot project for a sustainable way of living in London beyond meeting housing needs alone.

Resilient Cities Network · Resilient Cities Network · France

Article from the Resilient Cities Network describing Parisculteurs, the urban-agriculture support programme launched by the City of Paris in 2016. The '100 Hectares' charter has 82 partner organizations, and more than 50 projects have been realized with an equal number under development. Goals cited include shortening food supply chains, strengthening community cohesion, promoting healthy eating, food security, and ecosystem services.

Peri-urban agriculture is exposed to pressures toward diversification and multifunctionality, developing differently depending on territorial features. A paper studies the case of Trentino, an Italian Alpine region where the ratio of urban to rural domain is heavily skewed toward the latter and farms face environmental problems that jeopardize their competitiveness in mainstream markets, comparing the development of alternative food chains there with other Italian peri-urban areas. The mountain environment makes it difficult for farms to standardize products to large retailers' requirements, but alternative food chains endorse and communicate to the market the typicality of products and farmers' savoir-faire, the two main factors of added value. Survey data from short food chain consumers show they are inherently more attentive to these product cues, as a result of a lifestyle more attached to identity and origins, and prouder of their territory. These findings confirm that, given its structural and cultural traits, alternative food markets in the Trentino area are meaningful for the survival and development of the local agricultural sector.

Zsófia Benedek · Econstor (Econstor) · Europe

A literature review of international research on short food supply chains (SFSC) and their impacts, combined with findings on the types already established in Hungary. SFSC consumers tend to be more highly educated than average; traditional forms such as farmers' markets attract older people while newer forms such as community-supported agriculture and web-based value chains attract younger people. The review finds that clear scientific evidence of SFSCs' positive environmental, social or economic impact is not always available, and in some cases traditional food supply chains prove cheaper and more environmentally beneficial, concluding there is no generally preferable SFSC solution given their heterogeneity.

Ségolène Darly, Christine Aubry · Géocarrefour · Europe

This study examined the diversity of alternative agri-food networks (S3A) supplying collective catering (school and institutional canteens) in France, particularly the Île-de-France region, and their respective capacity to reestablish a link between food and urban agriculture. Distinguishing S3A based on proximity relations tied to the region's urban agriculture from S3A built on extended networks spanning distant production and consumption sites, the results show that whether Île-de-France farm products are introduced into canteens depends, beyond the level and nature of local supply, on multiple other local factors such as the existence of producer-referencing networks and the state of kitchen equipment and labor resources.

Gillean M. Denny · · United Kingdom

This study investigated the ability of urban agriculture (UA) to decrease food-related greenhouse gas emissions, using a life cycle analysis of tomatoes, produce surveys in East Anglia, and household surveys of 183 UA-practicing households. It found that UA participation can reduce an individual's tomato consumption emissions from 52.4 kg CO2e/yr to 11.2 kg CO2e/yr. This reduction amounts to 44% from a non-UA, low-emission diet and 78% from a supermarket diet.

Jan-Eelco Jansma, W. Sukkel, E.S.C. Stilma, Alex C. van Oost, A.J. de Visser · · Netherlands (Almere)

This case study in the Dutch city of Almere calculated that 6,200 hectares of conventional farming land (or 8,100 hectares for organic production) are needed to produce approximately 20% of the daily food basket for 350,000 future citizens. Local production reduces greenhouse gas emissions by an estimated 27,000 tonnes/year, a relatively small reduction as most products are already produced in the Netherlands. The study emphasizes that other aspects, such as food basket composition, local food distribution system redesign, consumer behavior, and fossil energy use reduction, must be considered for reducing food miles, fossil energy use, and greenhouse gas emissions.

This paper studies how various apples enter a community in London, using the apple as a device to analyze the city-region's food system and its connection to productive land. A multi-level analysis examined four arenas of procurement: mainstream retail (supermarkets), wholesale markets, direct links with producers (CSA box schemes, farmers' markets), and ecologically localized procurement (gleaning projects, community orchards). The study explores how these different journeys are understood and accounted for.
