This Wikipedia article on allotment gardening covers its history and national systems. In the United Kingdom, an 1809 engraving of Birmingham already shows allotment gardens surrounding the town, and the 'Great Somerford Free Gardens' in Wiltshire were founded in 1809; the 1908 Small Holdings and Allotments Act legalized allotments, amended in 1922 and 1950, with plot numbers rising from 244,268 in 1873 to a peak of about 1.5 million in 1918 before declining to roughly 300,000 by 2009. In Germany, 'Schrebergarten' plots trace to the 'Schreber movement' begun in Leipzig in 1864, formalized by the 1919 Small Gardens and Small Leaseholds Land Law; there are now about 1.4 million allotments covering 470 square kilometers, including 833 allotment complexes in Berlin alone. In France, family gardens that emerged in the late 19th century are managed by the 'Fédération Nationale des Jardins Familiaux et Collectifs,' with about 135,000 members. In the Netherlands, the article states the first allotment garden was founded in 1838, there are now 240,000 allotment gardens, and the 'Algemeen Verbond van Volkstuindersverenigingen in Nederland' (AVVN) was founded in 1928.

This Wikipedia article on 'city farm' states that an early city farm was set up in 1972 in Kentish Town, London, combining farm animals with gardening space — a combination inspired by children's farms in the Netherlands — and that other city farms followed across London and the United Kingdom. The article does not, however, provide further detail on the origin or history of the Dutch children's farms (kinderboerderij) themselves.

Stichting DakAkker · Stichting DakAkker (official) · Netherlands

The official site of DakAkker, a rooftop farm on top of the Schieblock building in Rotterdam. It describes itself as a 1,000-square-meter rooftop farm growing vegetables, edible flowers, and fruit and keeping bees, calling itself the largest open-air rooftop farm in the Netherlands and one of the largest in Europe. It is presented as an initiative of ZUS (Zones Urbaines Sensibles) and the Rotterdam Environmental Centre together with Optigrün Benelux and binder daktuinen, framed as part of Rotterdam's first city initiative 'de Luchtsingel.'

A floating dairy farm in the harbour of Rotterdam, described by its founders Peter and Minke van Wingerden as the world's first. It opened on May 13, 2019 with 32 cows, with plans to grow to 40. It is designed to use residual city products such as park grass and food waste to feed the animals, processes raw dairy into milk and yoghurt onsite for distribution in the city, and returns cow manure as fertilizer for public spaces. All power comes from solar panels, rainwater is collected on the roof, and milking, manure cleanup, and feeding are largely automated.

A case study of Herenboeren, a Dutch citizen-owned cooperative farm model started in 2016. Around 250 households jointly finance and govern each 'Herenboerderij', paying a one-off investment of roughly €2,000–2,500 and a monthly fee of about €45–80 (depending on location and meat consumption) in exchange for a weekly share of seasonal vegetables, fruit, eggs, and optionally meat. Professional farmers are employed to run nature-driven production. As of 2026 there are 23 operational farms across the Netherlands with more than 9,000 citizen members.

Moritz Schreber (1808–1861) was a German medical doctor and university lecturer born in Leipzig, who became director of the Leipzig Heilanstalt in 1844 and wrote about children's health and the social effects of urbanization. The eponymous 'Schreber movement' arose only after his death; the first Schrebergarten was established in 1864 by Leipzig school principal Ernst Innozenz Hauschild, who leased land for children's physical exercise.

German Kleingärten (allotment gardens) trace back to early-19th-century 'poor gardens' (Armengärten), with the first Schreber plot opened in Leipzig's Johannapark in 1865. Today about 15,000 clubs organized under 20 state federations and the national umbrella BKD manage roughly 867,092 registered plots, out of over 1 million plots nationwide covering about 46,000 hectares. The average plot size is 370 m²; as of 2008 the average transfer fee was €1,900 (€3,300 in large cities), average annual cost was €373, and the average user age was 60.

Germany's Federal Allotment Garden Act (BKleingG) was enacted on 28 February 1983 and took effect 1 April 1983 (last amended 19 September 2006, effective 1 October 2006). A Kleingarten must not exceed 400 m², and a garden shed (Gartenlaube) may be at most 24 m² including a covered terrace and must not be suitable for permanent habitation. Federal Court of Justice (BGH) case law holds that at least one third of the plot area must be used for growing garden produce for personal consumption, and that a Kleingarten site must comprise at least five individual plots.

Prinzessinnengärten was founded by the non-profit 'Nomadisch Grün' in July 2009 and operated an urban farm at Moritzplatz in Berlin-Kreuzberg (between Prinzenstraße and Oranienstraße), on roughly 6,000 m² of land that had lain fallow for over 60 years. Within a month of opening it had 100 growing beds, later expanded by 300 more, using a mobile container-based structure with plants grown in recycled bread crates, Tetra Paks, and rice sacks. It kept four beehives from September 2009, opened a garden café in 2010, expanded a garden kitchen in 2011, and won the Utopia Award in 2010.

The Intercultural Garden movement was founded in 1996 in Göttingen, Germany, partly on the initiative of migrant families, with an association formally established in 1998. It began with just three gardens in Göttingen but had grown by early 2006 to about 300 members from about twenty countries, while around the same period thirty independent garden projects existed nationwide with more being created. The Munich-based foundation Stiftung Interkultur coordinates and supports garden projects across Germany.

Plantlife · Plantlife · United Kingdom

An overview of Plantlife's 'No Mow May' campaign, urging people in the UK to stop mowing their lawns during May to let wildflowers grow and support bees and butterflies. The page states that approximately 97% of the UK's flower-rich meadows have been lost since the 1930s, and notes there are around 23 million gardens in the UK, meaning even small patches can add up. It encourages extending the practice beyond May into a year-round 'No Mow Movement' of managing lawns with mixed grass lengths for nature.

Buglife · Buglife · United Kingdom

An introduction to Buglife's 'B-Lines' initiative, which states that over 97% of the UK's flower-rich grasslands (an area the size of Wales) have been lost since the 1930s, and describes a nationwide network of flower-rich habitat 'stepping stones' linking existing wildlife areas across the countryside and towns. B-Lines have been mapped across England, Wales, Northern Ireland and Scotland, with a target to create and restore at least 150,000 hectares of flower-rich habitat across the UK.

Plinth · Plinth · United Kingdom

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.

Bundesverband der Kleingartenvereine Deutschlands (BKD) · Bundesverband der Kleingartenvereine Deutschlands (BKD) · Germany

The national statistics page of the German federation of allotment garden associations (BKD). It gives the base figures — 867,092 plots, 44,000 hectares, an average plot of 370 square metres — along with the three-tier structure of roughly 13,000 clubs, 502 district federations and 20 state federations, membership by state, and a ranking of plots in the 15 largest cities (Berlin about 66,000, Leipzig 39,000). The nationwide average wait for a plot is three years, rising to seven in Berlin and eight in Hamburg. It also shows the skew by which the eastern states excluding Berlin, holding 15 per cent of the population, contain more than half of all allotments.
