· Wikipedia · Cuba

This Wikipedia article on the Cuban economy states Cuban GDP declined at least 35% between 1989 and 1993 due to the Soviet collapse and loss of Eastern Bloc trade. Liberalized agricultural markets, letting state and private farms sell above-quota production at free-market prices, were introduced in October 1994. Reforms from 2011 onward expanded usufruct leasing of fallow state land to residents, with more than 150,000 farmers registered by 2012 leasing land from the government to grow surplus produce.

This Spanish-language Wikipedia article on Cuba's 'Special Period' states GDP contracted 36% between 1990 and 1993 following the Soviet collapse, and daily caloric intake fell from 2,845 kcal in 1989 to 1,863 kcal in 1994, below the recommended minimum of 2,100-2,300 kcal. Loss of access to Soviet oil drove a shift to permaculture and organic agriculture (the rise of organopónicos) with help from international technicians. Recovery began in 1994, with GDP reaching 1990 levels again by 2007.

Global Network of Lighthouse Farms (Wageningen University & Research) · Global Network of Lighthouse Farms (Wageningen University & Research) · Cuba

This profile of Organopónico Vivero Alamar from Wageningen University's Global Network of Lighthouse Farms describes a UBPC (Basic Unit of Cooperative Production) founded in 1997 by 5 cooperative members, starting as an 800 sqm manually irrigated tree nursery. It has since grown to 10.14 ha with 150 cooperative members, 42 of them women, including nurseries, a 0.45 ha greenhouse, a rustic lab for breeding entomopathogens, a mycorrhizal fungi propagation center, and small-scale fruit and vegetable processing facilities. The page notes the farm has had to close due to COVID-19-related economic hardship and wildfires.

This German Wikipedia article on the Edible City movement traces its origin to 2008 in Todmorden, England, where Pamela Warhurst and Mary Clear founded 'Incredible Edible'; by 2017 the UK Incredible Edible Network linked more than 100 groups. In Germany, the association 'Essbare Stadt' was founded in Kassel in May 2009 based on permaculture principles, while Andernach's municipal project began in 2009 and gained nationwide attention after being presented at Berlin's International Green Week in 2014. By 2017 over 140 such initiatives calling themselves 'edible' were found online. Since 2008, Toronto has promoted a comprehensive municipal program including community gardens, education, and food-waste initiatives.

This Wikipedia article covers Incredible Edible, an urban gardening movement started in 2007 in Todmorden, UK by Pamela Warhurst, Mary Clear and others, run on a 'three spinning plates' model of community (public-space growing anyone can pick from), business (supporting local food firms), and learning (food education). As of 2018 there were 120 official UK groups and over 700 worldwide; UK groups reported a 37% year-on-year rise in produce, 9,763 sqm of growing land, 4,861 participants, and 207 events. The project received a £500,000 grant from the Big Lottery Fund.

The 'Forest gardening' URL now redirects to a section within Wikipedia's merged 'Agroforestry' article. Per that section, forest gardening is a low-maintenance, perennial, woodland-modeled food production system practiced since prehistoric times in the tropics; horticulturist Robert Hart coined the term and adapted it for temperate climates in the 1980s. The article states Kerala, India has 'no fewer than three and a half million' forest gardens, citing one 0.12-hectare plot found to contain 23 young coconut palms, 12 cloves, 56 bananas, 49 pineapples, and 30 pepper vines.

· Wikipedia · United Kingdom

This Wikipedia article covers Robert Hart (1913-2000), a British horticulturist credited as the pioneer of temperate-climate forest gardening. He converted a 0.12-acre (500 sqm) orchard at his Shropshire home into a model forest garden structured in seven layers (canopy, low-tree, shrub, herbaceous, ground-cover, rhizosphere, and vertical/climber). The article also notes he followed a roughly 90% raw vegan diet, citing the Hippocratic maxim to 'let food be thy medicine.'

· Wikipedia · United States

This Wikipedia article covers the Beacon Food Forest, an urban food forest on public land in Seattle's Beacon Hill neighborhood, described as the largest food forest on public land in the United States. Jacqueline Cramer and Glenn Herlihy proposed the concept in 2009; the project received a $20,000 grant in 2010 and a $100,000 development grant in December 2011, with initial planting of 1.75 acres in September 2012. It added 27 P-Patch garden plots in 2014, expanded by 1.5 acres in 2019, and its Food Forest Collective gained nonprofit status in August 2017.

This is the European Commission's official Critical Raw Materials (CRM) page. It confirms that both 'Phosphorus' and 'Phosphate Rock' appear as separate entries on the EU's 2023 fifth CRM list. The page illustrates supply-concentration risk with examples for other materials (China supplying 100% of heavy rare earth elements, Turkey 99% of boron, South Africa over 71% of platinum group metals), but does not itself state a specific EU import-dependency figure for phosphorus or phosphate rock.

This official U.S. EPA page on 'The Effects' of nutrient pollution explains that excess nitrogen and phosphorus entering air and water cause algal blooms, degrading water quality and reducing dissolved oxygen. It states cyanobacteria can release toxins that sicken people and animals via contact, drinking water, or contaminated seafood, that nitrates in drinking water pose risks to infants, and that excess airborne nitrogen contributes to ammonia and ozone formation. The page itself contains no specific numeric statistics on economic damages or dead-zone area.

This Wikipedia article on the Haber (Haber-Bosch) process for industrial ammonia synthesis states that, as of 2018, the process produced 230 million tonnes of anhydrous ammonia per year, and that 'nearly 50%' of the nitrogen found in human tissues originated from it. Ammonia production is said to account for 1-2% of global energy consumption, 3-5% of natural gas production, and 3% of global carbon emissions, while nitrogen use efficiency is typically less than 50%, with farm runoff from excess use disrupting biological habitats. The article also credits the process with supporting global population growth from about 2 billion in the early 20th century to over 8 billion today.

This Wikipedia article on nitrogen fixation (the chemical process converting inert nitrogen gas into biologically usable nitrogen compounds) states that, as one legume example, nitrogen fixation by red clover can range from 50 to 200 lb/acre (56 to 224 kg/ha). It states the marine cyanobacterium Trichodesmium is thought to account for 'almost half' of nitrogen fixation in marine systems globally, and that the amount of nitrogen fixed in the ocean is at least as much as on land. It also credits the spread of Haber-process nitrogen fertilizer with helping expand the human population from about 2 billion in the early 20th century to over 8 billion today.

The URL for 'Peak phosphorus' now redirects to the Reserves section of Wikipedia's 'Phosphorus' article. Per a 2023 USGS estimate, world commercially extractable phosphate rock reserves are 72 billion tons, against 2022 world mining production of 220 million tons — implying roughly 300 years of supply at zero growth. Before new deposits were discovered in Norway in 2023, Earth's commercially affordable phosphorus reserves were expected to be depleted in 50-100 years. Reserve estimates are described as contested: a 2010 IFDC report is criticized by a 2014 review as presenting 'an inflated picture of global reserves,' particularly for Morocco, where largely hypothetical and inferred resources were simply relabeled 'reserves.' The article also states that a shortage in rock phosphate or significant price increases might negatively affect world food security. Mitigation measures cited include reducing agricultural runoff (no-till farming, contour tilling, windbreaks), incinerating phosphorus-rich sewage sludge and recovering the ash, and recovering phosphorus-rich materials such as struvite from waste — though current recovery technologies are described as not yet cost-effective given phosphorus market prices.

This Wikipedia article on 'metabolic rift' explains that German agricultural chemist Justus von Liebig, in his 1840 'Organic Chemistry in its Application to Agriculture and Physiology,' argued that if all solid and liquid excreta of city inhabitants were returned to farmers, land productivity could be maintained for centuries virtually unimpaired. Marx, combining his understanding of the labor process with Liebig's analysis, wrote in Capital Vol. 1 that capitalist production, by concentrating population in cities, 'disturbs the metabolic interaction between man and the earth' and prevents the return of soil constituents consumed by humans as food and clothing — defining this as 'an irreparable rift in the interdependent process of social metabolism.' John Bellamy Foster, in his 2000 book 'Marx's Ecology: Materialism and Nature,' reassessed Marx's ecological perspective, arguing the metabolic rift concept enabled the development of a critique of environmental degradation. The article notes that as food and fiber were transported over long distances, soil nutrients moved to cities as agricultural produce but were not returned as human and animal waste, producing 'a one-way flow of materials' — a plundering of the soil to sustain society's reproduction.

· Wikipedia · Japan

This Wikipedia article on night soil describes how, in the city of Edo, compost merchants gathered feces to sell to farmers, and that human excreta of rich people were sold at higher prices because their better diet presumably left more nutrients in it. Various historic documents detailing toilet-waste disposal procedures date from as early as the 9th century. The article states that after World War II the practice declined rapidly due to sanitation concerns and the spread of chemical fertilizer, and that today less than 1% of human waste is used for night soil fertilization.

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.

AVVN · AVVN (official) · Netherlands

The official site of AVVN, the Dutch federation of allotment/community gardening associations. It describes its mission as bringing together garden enthusiasts, associations, and green initiatives across the Netherlands, and operates a knowledge bank (covering social greening, vegetable gardens, natural/sustainable gardening, and association management), webinars and activities, and news articles. It is based at Rijnzathe 12, Utrecht. The homepage displays a member/affiliate count of '+1,489.' The page itself does not state a founding year, which could not be confirmed here.

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.' The roof also hosts 'Slimdak,' a test site for smart rainwater management. 'Dakennie,' its environmental education program for Rotterdam primary schools, is financially supported by Watersensitive Rotterdam, the City of Rotterdam's nature and environmental education division, and the Hoogheemraadschap Schieland en de Krimpenerwaard water authority. The page itself does not state an opening year, which could not be confirmed here.

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.
