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.

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.

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.

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.

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.

AÇIKSÖZ Sebahat · Tarım Bilimleri Dergisi · Turkey (Bartın)

This study investigated whether urban agriculture activities in Bartın, Turkey, could be organized as a cluster according to Cluster Growth Theory, and examined its cluster characteristics as part of the TR-26 Bartın Regional Development Project. While urban agriculture in Bartın was identified as having cluster characteristics and growth potential, the study found that a fundamental problem for its future development is weak coordination and cooperation among stakeholders. It proposes a model for urban agriculture activities for a "Bartın Urban Initiative" at the city level.

Bruce Frayne, Jane Battersby, Robert Fincham, Gareth Haysom · · South Africa

This study examines urban food security in South Africa, focusing on Cape Town, Msunduzi, and Johannesburg, and includes a critique of the City of Cape Town's urban agriculture policy. The abstract indicates that the policy was found to have significant shortcomings, particularly concerning local production and access to food. The research highlights various policy issues related to food access, dietary diversity, local production, and local markets within these urban contexts.

Dick Foeken · · Africa

This study analyzed the relationship between urban policy and the practice of urban agriculture by the poor, based on two studies in Nakuru Municipality, Kenya, and Morogoro and Mbeya Municipalities, Tanzania. The legal and policy setting in these towns was found to be confusing, and the poor generally do not benefit from policy measures, if policies exist at all.

Adnew, Walelign · National Academic Digital Repository of Ethiopia · Ethiopia

This study assessed the general performance and challenges of Micro and Small Scale Associations (MSSAs) in Wolkite and Boutajira city administrations, using questionnaires for 92 operators and interviews with 5 officials. Findings revealed that government supports have not ensured the sustainability of these associations, and service provision is not aligned with national strategy. MSSAs exhibit high closure rates, member dropout, fail to create long-term jobs, and show insignificant women's participation.

I. Ogunlade, O. I. Oladele, A. A. Falaki · University of Dar es Salaam Library Journal · Nigeria

This study investigated the socio-economic characteristics, information needs, and seeking behavior of 100 urban farmers in Ilorin metropolis, Kwara State, Nigeria, using a structured questionnaire. It found that urban farming was a supplementary activity for highly literate individuals, with farms mainly within the city and more animal than crop production. The study suggested that urban farmers could achieve better results if technical and financial support were provided, and recommended official government recognition for urban farming.

R. Machiridza, Emmanuel Manzungu · University of Zimbabwe Institutional Repository (University of Zimbabwe) · Zimbabwe (Harare)

Perceptions of urban agriculture in Harare, Zimbabwe, shifted from prohibition before 1980 due to environmental concerns to de facto government policy after independence due to increasing urban poverty. Land was initially allocated to co-operatives primarily for political support, creating tension between political patronage and environmental protection. Critics argue that authorities only accepted urban agriculture's reality two decades post-independence, driven by its potential for poverty reduction and economic development.

Zhang Xue-mang · Journal of Beijing University of Agriculture · China

This paper addresses the slow development of agricultural technology in Wuhan City, China. It states that Wuhan needs to import advanced agricultural technologies, research and disseminate techniques for fish and fowl culture, vegetable growth, and agricultural product processing. The paper emphasizes the necessity to improve modern distribution quality and strengthen government service and management in agricultural technological innovation, highlighting a current governance deficiency.

Randall Walsh · Journal of Urban Economics 61(2): 319-344 · United States

Uses a locational-equilibrium model that treats both privately held open space and land-conversion decisions as endogenous to evaluate the metropolitan-wide impact of open-space policy. Shows that once endogenous adjustment of private open space is allowed for, expanding public preserves can actually reduce the total quantity of open space across a metropolitan area. Also finds that different strategies for spending the same open-space budget have markedly different land-use and welfare consequences.

HU Yue-xiao · Nongye xiandaihua yanjiu · Global

This study on the industry orientation of urban agriculture, including trade, marketing, business model, and organizing orientations, identified problems such as industry parking, blurred functional orientation, and a lack of overall planning during urban agriculture orienting programs.

Laura Lawson · Journal of Planning History · United States

This historical review of US community garden programs since the 1890s reveals an ambivalent relationship between community gardens and the planning profession. While praised for serving environmental, social, and individual objectives, community gardens are largely ignored in long-range planning due to being perceived as opportunistic and temporary. This highlights unresolved tensions between professional planning and civic concerns, and between comprehensive planning and local interventions.

Olufunke Cofie, R. van Veenhuizen, Pay Drechsel · · Sub-Saharan Africa

Urban and peri-urban agriculture (UPA) significantly contributes to food supply, employment, livelihoods, and poverty alleviation in many Sub-Saharan African cities, providing diverse foods including perishable items. However, UPA production often carries health risks from polluted urban water and faces challenges due to limited semi-official recognition and support from city authorities, sometimes conflicting with planners regarding land tenure and water use. More data is needed for appropriate recognition of this sector.

Christopher M. Smith, Hilda E. Kurtz · Geographical Review · United States (New York City)

New York City community gardens have faced political contestation for thirty years, notably in 1999 when 114 gardens were slated for public auction and redevelopment. This article examines the controversy as a politics of scale, where garden advocates expanded the dispute beyond individual gardens and the city. The analysis highlights the significance of scale politics for grassroots organizations within a market-centric, neoliberal economic framework.

Derek Eaton, Thea Hilhorst · Environment and Urbanization · Africa

A 2003 paper examined the links between urban solid waste management and peri-urban agriculture in Bamako and Ouagadougou. Farmers near both cities value urban waste as an organic matter source and are willing to pay for it, but uncertain land tenure provides little incentive for safe disposal of dangerous elements in solid waste. Current plans to eliminate this recycling practice and promote large-scale composting are noted to be too costly for farmers, creating an incentive for illicit waste acquisition.

Liao Minghui · Nongye xiandaihua yanjiu · China (ChangshaZhuzhouXiangtan)

This paper discusses the essentiality of urban agriculture development in urban compact districts, highlighting its multiple efficacies including economic, social, and ecological benefits. Based on an analysis of typical examples in ChangshaZhuzhouXiangtan, the paper describes the current status and identifies many problems in urban agriculture. Finally, numerous countermeasures are proposed for these issues.

Nathalie Bertrand, Nicole Rousier · Revue de géographie alpine · France (Grenoble)

This study analyzed the economic role of agriculture in the Grenoble urban region, France. From an economic perspective, agriculture was considered an activity of relatively minor importance in this region, known for its strong technological development. However, in the regional master plan approved in 2000, farming occupies an essential position. The study aimed to understand the role of peri-urban agriculture in the preparation of the urban region's development plan by specifying its assigned functions and analyzing how agriculture has been considered in regional plans.

It identifies the position, role, and favorable conditions of urban agriculture, which embodies economic, social, and ecological functions. The study also highlights existing problems in Chongqing's agricultural industrialization and proposes countermeasures.

Karen Schmelzkopf · Urban Geography · United States (New York City)

This study examined the conflict over community gardens in New York City, arguing that it was a struggle concerning the right to space. The city, operating from an entrepreneurial governance perspective, claimed that the gardens represented a loss of exchange value and potential housing. The city used market economy rhetoric to dismiss incommensurable use values, thereby restricting rights to the city within a demonstration of power and "reason."

Charles W. Howe · Environment and Development Economics · Global

This study noted that in inappropriate legal and administrative settings, groundwater becomes an open-access resource, leading to excessive externalities. Competition between urban and agricultural sectors for limited groundwater can lead to crises if appropriate policy instruments are not used to mediate it. For non-renewable groundwater stocks, without economic and demographic development planned according to long-term criteria, there is a risk of overly rapid exploitation, unsustainable population levels, and inappropriate infrastructure investment.
