This article evaluates the level of Urban Agriculture Modernization in China's major cities, including Beijing, Shanghai, and Guangzhou, using the Analytic Hierarchy Process method. It finds that modern urban agriculture has developed rapidly based on urbanization and agricultural modernization, but disparate development is obvious in China. The article analyzes the reasons for this disparity and various factors for Urban Agriculture Modernization, revealing the mechanism and path for its realization.

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.

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.

Shahzad Kouser, Mr. Abedullah, Abdus Samie · The Pakistan Development Review · Pakistan (Faisalabad)

This study, conducted in 2006 with 200 farmers in two peri-urban villages of Faisalabad, Pakistan, estimated the economic values of negative health externalities from wastewater use in cauliflower production. While wastewater use appeared profitable without considering externalities, factoring in health costs strongly discouraged its use. The health externalities for a three-month cauliflower crop on 741 acres amounted to Rs 3.2 million, and for 5,283 acres of vegetables cultivated with wastewater in Faisalabad, the annual total was Rs 90.7 million. The findings indicate a significant economic loss due to wastewater use, suggesting that installing a water treatment plant is a viable option to minimize these external effects.

Lucette Laurens · Journal for Geography · France

This inquiry examines peri-urban agricultural spaces in Languedoc-Roussillon and the Montpellier agglomeration, France, which are characterized by a decline in agricultural activities and abandonment. These spaces are confronted with new, uncertain, and innovative dynamics, appearing as multifunctional spaces that need to be re-invented. The study highlights the paradox of these areas caught between appropriation for different uses and agricultural decline.

Adedeji Adedeji, H Oludare, Ademiluyi · Journal of Geography and Regional Planning · Nigeria

This discussion of urban agriculture and urban land use planning in metropolitan Lagos, Nigeria, frames urban agriculture as a crisis response and survival strategy for the urban poor that contributes to food security, while stating that urban agriculture production systems can pose risks to public health and the environment through inappropriate or excessive use of agricultural inputs — including pesticides, nitrogen, and raw organic matter containing heavy metal residues. It recommends that urban land use planners promote multifunctional land use and greater community participation in managing urban open spaces.

P. S. Datta, Shipra Tyagi · · India

Peri-urban agriculture in the Delhi-NCR area is highly dependent on groundwater availability amid rapid urbanization. This study integrates dynamic δ18O isotopic composition data on groundwater with static data such as elevation of recharge sites to delineate potential recharge zones and hydrodynamic aquifer zones. Significant δ18O-elevation relationships were found (r² = 0.808 to 0.982), with recharge-site elevation resolutions of about 20m in the northwest and 75m in the southwest, identifying potential recharge zones at elevations of 210-230m in the northwest and above 260m in the south. However, variation in groundwater isotopic composition over time indicates that the corresponding aquifers are relatively small and of low productivity, and points to the likely presence of many low-permeability zones in the northwestern recharge areas — a constraint on the groundwater resources that sustain peri-urban agriculture there.

Erastus K. Kang’ethe, Delia Grace, Thomas F. Randolph · East African Medical Journal · East Africa

This study synthesizes current knowledge on urban agriculture (UA) in East Africa, focusing on its human health impact. It identifies UA as an important source of food security, but notes that many zoonotic and food-borne diseases are associated with it, with a lack of evidence on human health impact and management. Major constraints include illegality and limited access to inputs and markets, indicating a need for more research to understand both positive and negative health impacts.

Sue Wells · Western CEDAR (Western Washington University) · Tanzania

This paper examines the transferability of six Smart Growth concepts to Tanzanian cities (Dar es Salaam, Arusha, Mwanza, Dodoma, Zanzibar) given their extreme poverty and agrarian base. Primary research conducted in May-June 2007 and related publications were used. The study suggests that Smart Growth strategies from the Global North may be unsuitable for the Global South, indicating that urban agriculture in this context presents both a promise and a problem.

Nathan McClintock · · United States (California)

This paper uses urban political ecology to explore the rise of urban agriculture (UA) in Oakland, California, where the city aims to source 30% of its food locally, partly from UA in "food deserts." The analysis argues that 20th-century industrial capital flows and racialized urban planning concentrated capital devaluation in the flatlands, leading to the creation of food deserts. Food justice activists are mobilizing through UA to counter these uneven transformations.

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.

Wei Xu · Chinese Journal of Population Resources and Environment · Global

This study examines the interaction between the sustainable development of urban agriculture and the increase in peasants' income, treating them as a combined system. It identifies a synergistic relationship between increased peasant income and urban agriculture development, but also a competitive relationship between maximizing short-term income and ecological sustainable development. The research suggests that a sustainable urban agricultural resource allocation mechanism can foster coordination and positive interaction, with urban circular agriculture economy being a basic strategy for this coordination.

Nathan McClintock · eScholarship (California Digital Library) · United States (California)

This paper explores the rise of urban agriculture (UA) in Oakland, California, using an urban political ecology framework. A macro-level structural analysis of Oakland's history reveals how 20th-century industrial capital flows and racialized urban planning concentrated capital devaluation in the flatlands, ultimately giving rise to food deserts. The study suggests that food justice activists are mobilizing through UA to counter these uneven transformations, despite critiques that some urban garden programs are neoliberal, emphasizing self-betterment while filling state-left gaps.

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.

Pay Drechsel, Olufunke Cofie, R. van Veenhuizen, Theophilus O. Larbi · Irrigation and Drainage · West Africa

Informal irrigation in urban and peri-urban agriculture (UPA) in West Africa offers benefits but is often hindered by water pollution, threatening public health. A multi-stakeholder process implemented since 2005 in six West African cities, including Accra, Ghana, aimed to integrate UPA into sustainable urban development. However, an internal lesson learned was that local partners may not prioritize every project, and capacity-building efforts might not provide expected incentives for commitment.

Erin Foster West · · United States (Minneapolis)

This study explores the interaction between community gardens and public agencies in Minneapolis and Hennepin County, United States. It identifies that despite a large number of community gardens in the Twin Cities Metro Area, there is no comprehensive city policy for community gardening, making land acquisition difficult as vacant land becomes scarce. The research inventories public policies related to land use, water, and compost specific to community gardens, highlighting the need for public agencies to provide essential services.

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.

Bertha Camacho Tuckermann · Knowledge Management for Development Journal · Cuba

An action-research study within an Urban Agriculture project in Cuba identified challenges in integrating learning and change into the monitoring and evaluation (M&E) of development projects. The main challenge was that the project team did not recognize M&E as a learning tool, believing results could be used against their work. A lack of time for learning and knowledge sharing was another observed challenge. To address these, resistance was overcome through dialogue, reflection, and action, leading to team empowerment, and the role of an external facilitator proved key in steering the learning process.

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.

Lynn A. Staeheli, Donald W. Mitchell · · United States (New York City)

This book explores the complex relationship between power, politics, and public space across various US cities, including Washington, D.C., Santa Fe, San Diego, Syracuse, and New York City. Chapter 5 specifically addresses the struggle for public access and control in New York's community gardens. The work reveals challenges in governance and public access within these urban spaces.

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.

Stephanie Buechler, Gayathri Devi Mekala, B. Keraita · Victoria University Research Repository (Victoria University) · Global

This 2006 global study from Victoria University discusses wastewater use in urban and peri-urban agriculture for crop production and aquaculture, noting its role in generating livelihoods and providing cheap produce. However, the study emphasizes that clear policy guidelines and careful research are needed to prevent potential negative impacts on human health and the environment from wastewater reuse.

Halidou Koanda · Infoscience (Ecole Polytechnique Fédérale de Lausanne) · Sub-Saharan Africa

In Sub-Saharan Africa, faecal sludge management practices are often financially unviable due to widespread lack of municipal involvement, paucity of legal provisions, and absence of stakeholder coordination. This leads to indiscriminate dumping of faecal sludge in urban areas or its untreated use in urban agriculture. These practices pose permanent and serious health risks and contaminate scarce ground and surface water. This research aims to develop an innovative strategic planning approach for sustainable urban faecal sludge management to minimize public health and environmental risks.

Juliana Arruda, Nilson Antonio Modesto Arraes · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Brazil (Campinas)

A 2005 study in Campinas, Brazil, analyzed the city's Community Garden Program (PHC) to support the formulation of new urban and peri-urban agriculture policies. Analysis of PHC management revealed an almost total disengagement between the program and sectoral policies such as education, health, and social action. However, individual actions were found to be important for project implementation and success, and the projects were significant in the lives of beneficiaries.
