Mohammed Murtala Ruma, Abdullahi Usman Sheikh · African Journal of Environmental Science and Technology · Nigeria (Katsina)

This paper investigated the status of wastewater reuse in urban farming in Katsina, Nigeria, by interviewing 120 households out of 250 registered with the Katsina Urban Planning Authority. It was found that wastewater reuse in urban farming is a full-time, sole income earner for many households and is indispensable for this semi-arid city. However, the urban planning process has not officially recognized or given attention to this important activity.

Satoru USHIROZAWA, Masao Makiyama, Takaaki Takahashi · JOURNAL OF RURAL PLANNING ASSOCIATION · Japan

This study evaluated the benefits of Kleingartens (stay-type allotment gardens) for local municipalities in Japan, using data on investment, maintenance costs, and user fee revenue. A main finding is that municipalities, on average, incur a considerable deficit, with a typical Kleingarten having an estimated annual deficit of approximately 240,000 yen. The study concluded that it is difficult for municipalities to achieve profit by providing Kleingartens, even with marginal improvements from increased user fees.

沈建华, 储健 · 江苏农村经济 · China (Nanjing)

In recent years, Nanjing, China, has promoted the development of urban agriculture amidst rapid urbanization, contributing to increased farmer income and enriched urban life. However, the urban-rural divide remains relatively obvious. A key challenge is how to narrow this urban-rural gap and accelerate integrated development during the "12th Five-Year Plan" period.

Kohei Makita, Eric M. Fèvre, Charles Waiswa, Mark Bronsvoort, Mark C. Eisler, Susan C. Welburn · Land Use Policy · Uganda

This paper describes a spatial representation of the peri-urban interface (PUI) of Kampala, Uganda, and identifies socio-economic factors related to peri-urbanicity using rapid rural mapping. It notes that urban and peri-urban agriculture (UPA) in rapidly expanding cities carries public health risks, such as zoonotic disease transmission. The study provides a methodology for describing the PUI in developing countries.

김태곤, 박문호, 허주녕 · 한국농촌경제연구원 기본연구보고서 · South Korea

This study aims to identify the current status and challenges of urban agriculture and propose solutions. Urban agriculture faces chronic problems including securing farming land due to rising land prices, management insecurity resulting from farmland diversion or lease, and increased production costs due to environmental regulations. These issues restrict the range of agricultural management.

Alec Thornton, Etienne Nel, Godfrey Hampwaye · Development Southern Africa · Zambia

A review of urban agriculture in Zambia's four largest cities revealed that despite attempts by the Kaunda government in the 1960s–1970s to create supportive policies, there is currently a near absence of institutional support, constraining farmers' activities. A survey of 400 farmers confirmed the value of urban agriculture as a survival strategy but also highlighted the lack of necessary support measures.

Eric L. Hazzard, Elizabeth Moreno, Deborah Lane Beall, Sheri Zidenberg‐Cherr · The FASEB Journal · United States (California)

This study evaluated the effectiveness of the California Instructional School Garden Program (CISGP) grants by surveying 749 grantee schools. It found that the development, sustained use, or expansion of gardens was less than expected (p=.01), and fewer schools than expected reported using gardens for instruction (p<.001) or to teach academic subjects (p<.003). Less than 40% of schools reported accomplishing all their garden goals with the funds.

杨卫丽, 李同昇, 陈波 · 经济导刊 · China (Xi'an)

The promotion of integration in China's Xi'an-Xianyang metropolitan area, while bringing urban economic prosperity, has also created unprecedented pressure on the ecological environment and social problems. Specifically, the "urban-rural dual structure" and "three rural issues" are the biggest bottlenecks encountered during the urbanization process.

Lisen Hendeberg · · Sweden

This study compared Ebenezer Howard's garden city ideals with contemporary urban farming movements in Sweden through a literature review and analysis of three active movements. It found that when garden city ideas were implemented in Sweden between 1905 and 1930, much of the original ideological basis for self-sufficient small towns and collectively owned land was lost. While similarities exist in ideological starting points, their approaches to change differ.

Emma Schroeder, Krishna Ramanujan · · United States

In his 2010 interview with Emma Schroeder, Krishna Ramanujan shared his memories of the Eagle Heights Community Garden. Mr. Ramanujan discussed the ethnic diversity of the gardeners, the tensions between the Gardens and the University, and balancing graduate school while raising a young family in the Eagle Heights community. This interview was conducted for inclusion in a Master's thesis on the Eagle Heights Community Gardens.

Diana Lee-Smith, L. J. A. Mougeot, Michael Levenston, Peter Mann, Katherine Brown, Jerry Kaufman · Journal of Agriculture Food Systems and Community Development · Global

This reflection on the urban agriculture movement notes that 19th and early 20th-century urban reforms, including urban gardens, aimed to improve living conditions in industrial cities. However, these initiatives also shifted the burden of sustenance from industrialists and fair-wage policies onto urbanizing families, particularly women. Despite this, garden spaces provided nourishment and retreats in densely populated areas.

Kwasi Appeaning Addo · Remote Sensing · Ghana (Accra)

This paper discusses the need for sustainable management of urban and peri-urban agriculture in Accra, Ghana. A lack of reliable data on the extent of urban/peri-urban areas used for farming has hindered the development of sustainable policies to manage urban farming in Accra. Ground-based survey methods are problematic and prohibitively expensive, making accurate assessment of urban farming's future role difficult.

C.J.M. van der Lans · Socio-Environmental Systems Modeling · Global

This study analyzes the sustainability of international horticulture initiatives, including those by Dutch businesses and Wageningen UR, particularly questioning their continuity if foreign support withdraws and their viability given limited foreign currency in developing countries. Using the Multi-Level Perspective framework, two cases were examined: an Integrated Pest Management project in Ethiopia's floriculture sector and the transition to large-scale urban agriculture in Detroit, USA. The report raises concerns about the long-term economic viability and self-sufficiency of these initiatives.

FU Li-hua · 自然资源学报 · China (Shanghai)

A study of Shanghai, China, building an evaluation index system reflecting the characteristics of sustainable urban agricultural development, using a combination of the analytic hierarchy process (AHP) and the information entropy method to determine index weights, and applying it to time-series data from 1993 onward to produce a quantitative, comprehensive appraisal. The results comprise three findings. First, the population subsystem progressively became a main obstructive factor for sustainable urban agricultural development, the economic subsystem gradually became a main contributing factor, and the social subsystem grew more important in raising development capability, while cultivated land resources became increasingly scarce and continued to decrease, constraining improvement, and the heavy burden of agricultural production's self-pollution had a negative effect on the overall upgrade of development capability. Second, the resource (R-D) composite index was not high and declined significantly, averaging 1.9090 over 1993-2006 and falling 6.00% per year from 2.5336 in 1993 to 0.5541 in 2006, indicating growing resource pressure; the environmental (E-D) composite index was smaller and changed little, remaining around 1.0000 in most years, with environmental pressure staying high but stable. Third, after earlier wave-like fluctuations, the overall composite evaluation index entered a sustained, steady climb, with a significant increasing trend in development capability.

Nicola Silvestri, E. Bonari · CINECA IRIS Institutial research information system (University of Pisa) · Italy

Focusing on the area around Lake Massaciuccoli in Tuscany, Italy, this paper discusses the relationship between the management of peri-urban agricultural land — the transition zone between city and countryside — and the lake's eutrophication problem. It argues that proper management of the extensive agricultural areas within this heavily anthropized territory could contribute significantly to resolving the lake's eutrophication through management and structural interventions, while noting that partially reorganizing existing agricultural models carries both cost and difficulty.

Mark Matsa, Thomas Marambanyika · Journal of Environmental Extension · Africa

A study assessing concentration levels of lead (Pb), cadmium (Cd) and sulphides (SO2) within and around Gweru's sole official waste dumpsite in Zimbabwe. Harsh economic conditions in the city have driven further expansion of urban agriculture on open spaces, with residents growing staple food crops such as maize and sweet potatoes for subsistence on numerous plots surrounding the dumpsite; the study states that ingesting crops grown near the dumpsite is likely to put residents' lives at risk. Soil sampling points along transects on and around the dumpsite were randomly selected using ArcView GIS, with sulphide concentrations measured by Leco machine and lead and cadmium by atomic absorption spectrometer. Independent t-test results showed the concentration levels of the three pollutants were significantly elevated from one sampling point to the next, within and around the dumpsite.

Zhigang Wei · Journal of Qingdao Agricultural University · China

A comprehensive survey of agricultural structure and layout in Qingdao, China. It states the sector has achieved transformation and upgrading, with growing agricultural industrialization and increasingly optimized layout of agricultural areas approaching cluster-scale planting and breeding industries. However, it reports that further adjustment of planting structure faces major bottlenecks due to limits on arable land and food security: the traditional small-scale fish-farming model seriously restricts further development of animal husbandry and aquaculture, and fluctuating agricultural product markets combined with a lack of competitiveness are affecting the agricultural industry's layout. It concludes that crop structure needs further adjustment, that production should be scaled up, specialized and standardized, and that urban agriculture should be emphasized to expand agricultural functions.

Cantor, Kelly-M · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Colombia (Bogotá)

This study analyzed urban agriculture practiced by forcibly displaced residents and by vulnerable populations living in poverty in southern Bogotá and the Soacha locality, Colombia, using a livelihoods approach and drawing on 20 local actors and public/private institutions that had run urban agriculture programs as its information source. It found that urban agriculture carries symbolic value as a livelihood and occupational alternative, framed around collective wellbeing beyond monetary value, and reflects a struggle by peasant identity to survive within city life—but concluded that it is not an integrally sustainable activity.

Emma Schroeder, Julie Schneider · · United States (Eagle Heights)

Julie Schneider's 2009 interview discusses her five years at the Eagle Heights Community Garden. She described vegetables grown, organic gardening, rules and restrictions, and tensions with the university, as well as changes in the community gardens since the early 1990s. This interview was conducted for a Master's thesis on the Eagle Heights Community Gardens.

Alec Thornton · Development in Practice · Fiji

This article examines the impact of Fiji's squatter-resettlement scheme on the livelihoods of 'farming squatters' engaged in urban agriculture. Interviews with key informants and squatter residents revealed contrasting attitudes and approaches, indicating that the scheme threatens these livelihoods. The article suggests a more participatory process to address the needs of 'farming squatters'.

Mattia Celio, Christopher A. Scott, Mark Giordano · Geographical Journal · India (Hyderabad)

A study in Hyderabad, India, examined urban water capture and its impacts on pre-existing claims, particularly agriculture. Urban water appropriation often leads to conflict with existing water uses. The findings indicate that the magnitude and direction of impacts from urban water transfer on agriculture vary spatially and temporally, depending on location-specific rainfall patterns, existing water infrastructure and institutions, and farmers' adaptive capacities, including recourse to groundwater.

Liang Wei · Anhui nongye kexue · China (Dingxi)

This study analyzed the advantages, disadvantages, and existing problems in the development of urban agriculture in Dingxi City, China. Strategic concepts and countermeasures were proposed to provide consultation for urban agriculture development in Dingxi City and similar regions.

Remi Adeyemo, F. Kuhlmann · Tropicultura · Nigeria

This paper evaluates the efficiency of resource use in urban food crop production in five districts of two cities in southwestern Nigeria, based on an effective sample of 120 respondents. The analysis showed that urban food crop production is profitable, with an average revenue of N51,294 per hectare and a gross margin of N23,688. However, there was disequilibrium in resource use, with planting seeds and agrochemicals used efficiently, but land and labor used inefficiently, indicating that urban food crop production has not yet attained an optimum level of resource combination.

Clara Irazábal, Anita Punja · Journal of Urban Affairs · United States (Los Angeles)

This qualitative case study analyzes the destruction of the 14-acre South Central Farm in Los Angeles in July 2006, arguing it was a landscape of resistance against discriminatory legal and planning practices. The study contends that environmental justice and planning ethics provided a substantive rationale for the city to prevent its dismantling. This case highlights a failure in governance to protect community gardens threatened by dismantlement in capitalist societies.

Mark Redwood · Open House International · Global

Urban farmers often produce food on land with limited or no security of tenure, exposing them to the risk of being evicted for more profitable land uses. Without legal status, most forms of credit are inaccessible to farmers, pushing them to the margins. Recent projects suggest that banking systems need to develop a methodology to value informally controlled lands and indicate that advocacy groups can increase security and access to land for urban farmers.
