The term chilometro zero entered common use in Italian food discourse in the early 2000s, initially through the writing of Carlo Petrini and the Slow Food movement based in Bra (Cuneo). It describes food produced and consumed within a small geographical radius — in practice most definitions used by Italian regional authorities set the threshold between 50 and 70 kilometres from the point of production to the point of sale.
Northern Italy — specifically Piedmont, Lombardy, Emilia-Romagna and to a lesser extent Veneto — concentrates a significant proportion of Italy's zero-km farming operations, for reasons related to both agricultural history and proximity to dense urban centres with purchasing power to sustain direct-sale models.
The concept and its legal status
There is no single national Italian law that defines or certifies chilometro zero as a food label. Several attempts have been made in Parliament to introduce a legal framework — including a bill drafted in 2010 that never passed into law — but as of 2025 the designation remains voluntary and unregulated at the national level.
A number of Italian regions have enacted their own guidelines. Lombardy's regional government has issued documentation recommending that public procurement (schools, hospitals, municipal canteens) prioritise products from within the regional territory, and in practice uses km 0 as a marketing descriptor in official communications. Emilia-Romagna has integrated short-chain food supply into its Rural Development Programme, with co-financing from the EU's FEASR (European Agricultural Fund for Rural Development).
The absence of a binding national definition means that a vendor applying the km 0 label is largely self-certifying. Consumer-facing media including Altroconsumo have noted instances of the label being applied to products sourced from well beyond any reasonable radius.
Piedmont: structure and geography
Piedmont's agricultural geography is shaped by three distinct zones: the Po plain in the south and east (intensive arable and dairy), the Langhe and Monferrato hills (viticulture, truffle, hazelnut), and the Alpine foothills and valleys (small mixed farms, summer pasture). Zero-km producers with a direct market presence are concentrated primarily in the Po plain municipalities around Turin and in the Cuneo province.
Coldiretti's Campagna Amica network
The Coldiretti confederation operates the Campagna Amica network, which as of 2024 comprised approximately 10,000 direct-sale points across Italy, including dedicated markets, farm shops (spacci aziendali) and stalls within existing periodic markets. In Piedmont, the network lists several hundred participating farms. Entry into the network requires that at least 80% of products sold be produced by the vendor's own farm or by another Campagna Amica member within the same regional circuit.
The Campagna Amica markets held near Turin's Porta Palazzo and in the Lingotto district are among the most consistently attended in the Piedmont network, drawing producers from the Chieri and Carmagnola areas, both historically associated with vegetable cultivation for Turin's urban market.
Lombardy: peri-urban agriculture and supply
The Milan metropolitan area is surrounded by one of Europe's most intensively cultivated peri-urban agricultural zones. The Parco Agricolo Sud Milano — a protected agricultural park established in 1990 immediately south of the city — covers roughly 47,000 hectares and contains several hundred operational farms. The park's charter explicitly prioritises short-chain and local supply as a secondary function of the protected area.
Milan hosts a dedicated zero-km market at the Darsena canal district, operating on Saturdays. The Darsena market was established in its current form in 2015 and allows only producers who can document that their farm is located within 70 km of the city. As of the 2023 season, the market listed 65 participating producers, covering vegetables, dairy, meat, eggs and processed products such as conserves and pasta.
Brescia and Bergamo provinces
The eastern Lombardy provinces of Brescia and Bergamo contain a number of certified organic farms that distribute through direct-sale channels. The Val Camonica valley north of Brescia has a cluster of small farms producing heritage grain varieties and mountain vegetables under the Associazione Granai della Memoria documentation framework. Several of these producers attend the weekly Friday market in Breno (Brescia) and the Saturday market in Bergamo's Città Alta.
Emilia-Romagna: the cooperative model and direct sale
Emilia-Romagna is Italy's most cooperative-dense region. The agricultural cooperative tradition here is deep — the first Emilian agricultural cooperatives were founded in the 1880s — and it coexists with a more recent direct-sale movement that has partially emerged as a counterpoint to the cooperative structure's tendency toward large-scale consolidation.
Bologna and Modena both host regular direct-sale markets operated independently of the cooperative system. The Mercato della Terra in Bologna — a Slow Food-affiliated market held on the last Saturday of each month at the Ex-Mercato Ortofrutticolo — requires that participants sell only self-produced goods and meet a provenance radius of 60 km. Produce documented at the market includes heirloom tomato varieties from the Bolognese hills, hand-harvested saffron from the Appennino Bolognese, and several pork products from small-scale Mora Romagnola pig breeders.
The Bolognese heirloom tomato variety Cuore di Bue (ox-heart) and the flat parsley variety Ricciolino both appear on the Ministero dell'Agricoltura's Prodotti Agroalimentari Tradizionali (PAT) list, which documents traditional Italian food products at risk of disappearance. Their continued presence in Bologna's direct-sale markets is one mechanism through which these varieties remain in cultivation.
Practical considerations for documenting zero-km provenance
Several Italian organisations provide frameworks for verifying producer provenance claims at markets:
- Campagna Amica (Coldiretti): maintains a directory and certification mark for participating farms. Verification is internal to the confederation.
- Slow Food Presidia: documents specific traditional products and the producers maintaining them, with published criteria for each Presidium.
- BioDistretto: a network of organic districts, several of which are in northern Italy, that track producer membership and territorial boundaries.
- AIAB (Associazione Italiana Agricoltura Biologica): maintains a registry of certified organic operators, which can be cross-referenced against claimed market provenance.
None of these frameworks offers real-time, exhaustive coverage of all direct-sale operators. For a market visitor, the most practical check remains asking the vendor for the name and municipality of their farm and cross-referencing against available databases — a process that Coldiretti's public-facing tools partially support.
