This study of market gardeners in Khartoum, Sudan, reveals limitations in the integrating capacity of urban agriculture. Uncontrolled urbanization in the capital creates intense competition for property, restricting the potential integration of farm-workers in the downtown area. This activity is strictly commercial and primarily carried out by a migrant population.

Juliana Portela do Rego Monteiro, Maria do Socorro Lira Monteiro · RePEc: Research Papers in Economics · Brazil

A study of 43 urban gardens in Teresina, Piauí state, Brazil, analyzed via primary data collection and field research whether the gardens function as a means of generating work and income and improving socioeconomic conditions without degrading the environment. Most gardeners were women over 45 with incomplete elementary education, earning up to one minimum wage, originally from the state's interior, who had worked in agriculture before joining the gardens and worked them as a family. Most had not participated in training since entering the program, used their own resources for production, concentrated 70.08% of output on cilantro, chives and lettuce, and sold produce mainly on-site; soil amendment relied mostly on manure with limited chemical fertilizer, and only 36.81% of gardeners used pesticides. The study concludes that low remuneration, stemming from limited crop diversity, poor organization and lack of financing, led some family members to seek alternative income.

Soren T. Anderson, Sarah E. West · Regional Science and Urban Economics 36(6): 773-789 · United States (Minneapolis-St. Paul)

A hedonic analysis of home transactions in the Minneapolis-St. Paul metro area finds that the value of proximity to open space is higher in dense neighborhoods, those near the central business district, high-income, high-crime, or with many children. Warns that applying the metro-wide average value to a specific neighborhood can substantially overestimate or underestimate what open space is worth there.

Nkawkaw Afriyie, Kofi Adziri, Yaw Asare, Amoako Gyamfi · Zenodo (CERN European Organization for Nuclear Research) · Ghana

A thematic analysis synthesized existing studies on community gardening impact measurement in Accra, Ghana, focusing on methodologies. While varied methods were reported, a notable theme emerged regarding the mixed results and challenges in accurately gauging the impact of community gardening on urban food security indicators, such as vegetable consumption rates among participants. This review underscores the importance of empirical data for understanding the effectiveness of urban agricultural interventions, but highlights methodological inconsistencies.

Levon T. Esters, Blannie E. Bowen · Journal of Agricultural Education · Global

This study investigated factors influencing career choices among graduates of an urban agricultural education program. While former students identified parents and friends as influential, and cited various reasons for their career paths, a discriminant analysis model could not distinguish between those who chose agricultural careers and those who did not after completing the secondary agricultural program.

Sun Guo-xing · Tianjin Agricultural Sciences · China (Tianjin)

This article analyzes the mutual impacts of urban agriculture and urbanization in Tianjin, China, and suggests ways for urban-rural integrated coordinated development. It discusses key strategic problems for further development based on the current situation of urban agriculture and urbanization. The article reports on strategy and general development trends for urban agriculture and urbanization.

Alice J. Hovorka · Annals of the Association of American Geographers · Africa

This study empirically examines the effects of gender on commercial urban agriculture in Greater Gaborone, Botswana, using a conceptual framework bridging sociospatial and human-environment geography. It found that gender clearly shapes both the quantity and type of foodstuffs produced for the urban market, with men and women farmers entering production and participating in this economic sector on unequal terms defined by socioeconomic status, location, and environmental interaction. The study argues that gender relations of power, as produced through sociospatial and human-environment relations, remain an unequal structuring force in the sector that must be accounted for if urban agriculture is to support food security and economic growth.

Troy D. Glover · Leisure Sciences · Global

This 2004 global narrative inquiry explored a community garden as a social context for social capital among gardeners. The study found that social capital can be both a benefit and a cost, depending on an individual's position within the social network. This suggests a potential for inequitable or corrupt application of social capital within community garden groups.

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.

Jianguo Dai · Journal of Shenzhen Polytechnic · China (Shenzhen)

Urban agriculture in Shenzhen faces problems including decreasing farmland, inadequate skilled farmers, poor disaster resistance, immature insurance, increasing contamination of water, soil, air, and agricultural products, and poor modern enterprise management. Strategies proposed for sustainable development include specific laws, pollution protection, education, research, technology application, industrial technology application, leisure agriculture development, and diversification.

Ching‐Fu Chen, 黃琮聖, 閻淑慧, 蕭玉華, 蔡郁芬 · · Taiwan

This study surveyed 180 participants from five city farms in Taichung, Taiwan, between March and April 2004, to assess service quality, satisfaction, and intentions. While perceived service qualities were generally good, overall satisfaction was rated as "slightly satisfied," and renewal and recommendation intentions were rated as "slightly agreed," indicating significant room for improvement. Service content and management had significant effects on overall satisfaction, management on renewal, and service content on recommendation.

Clare Rishbeth · Journal of Urban Design · United Kingdom (London)

This paper investigates how urban greenspace can be designed and managed to reflect ethnic diversity and how this is perceived by users, using two case studies of community gardens in London. It found some differences in the response to the gardens by people from different ethnic backgrounds. The use of obvious symbolism was not necessarily a primary means of encouraging users from a wide range of ethnic backgrounds, though appreciated for educational and design strengths. Concern is expressed about aspects of the physical and psychological containment of ethnic groups in fixed places and identities leading to the perpetuation of stereotypes.

Kenny Lynch · · Indonesia (Jakarta)

This piece reviews the literature on urban agriculture (UA), noting that Bryceson (1993) provides documentary evidence from as early as 1939 of UA's importance during and after the Second World War, and that the UN University's Food Energy Nexus research programme in the mid-1980s prompted researchers to examine agricultural cultivation within city boundaries more seriously. Since then, a significant body of literature has developed around a central debate over whether urban agriculture is beneficial, summarized by Lynch (2002). This summary is described as having two problems: it assumes urban agriculture is a homogenous activity with universally similar impacts, and it is largely viewed from the perspective of a city's population, so urban agriculture tends to be seen as beneficial for food, employment and the environment with little consideration of its impacts on the rural-urban food supply. This led Lynch, Binns and Olofin (2001) to argue that urban agriculture should instead be considered part of the broader urban food supply system.

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.

James M. Wolf, M S van Wijk, X Cheng, Yuanhao Hu, C.A. van Diepen, A.W. Jongbloed, H van Keulen, C H Lu, R.P. Roetter · Environment and Urbanization · China (Beijing)

This paper reviews agricultural production trends in Beijing Municipality and their impact on water quality. Rapid urbanization and agricultural intensification have led to concerns regarding water resource quantity and quality. The agricultural sector, while supplying food, is a major water user and has contributed to significant water supply-demand gaps and high levels of water pollution, particularly from intensive crop, vegetable, and livestock production.

This 2003 research brief investigated the experiences of Community Supported Agriculture (CSA) growers on the central coast of California. The study examined their motivations, economic viability, challenges, and issues related to equal access to their products. The research brief indicates that challenges and issues of equal access are present in CSA projects.

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)

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.

N. Bertrand, Nicole Rousier · HAL (Le Centre pour la Communication Scientifique Directe) · France (Grenoble)

In the Grenoble urban region, agriculture holds relatively minor economic importance despite the region's strong technological development. However, the region's 2000 master plan assigned an essential role to farming. Peri-urban agriculture is a key issue in planning policies, engaging local officials, planners, and farming community representatives, but its economic weight remains low.

G. B. Luilo, Othman C. Othman · Journal de Physique IV (Proceedings) · Tanzania (Dar es Salaam)

This study measured heavy metal levels (cadmium, manganese, lead, and zinc) in Cynodon grasses near roads in Dar es Salaam City, Tanzania. Mean levels of lead and zinc varied exponentially with distance from the road up to 15m and correlated with average daily traffic, suggesting vehicular sources. For public health reasons, it is recommended that pasture grasses in road vicinities not be used for foraging dairy cattle and goats.

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.

You Shao · · China (Chongqing)

This paper examines the development of urban agricultural industrialization in the metropolitan periphery, using Chongqing, China, as an example. 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.

Yansui Liu · · China

China's agricultural structure adjustment from 1997 to 2000 focused on comprehensive adjustments of quality, varieties, industrial, and regional structures. While distinctive agriculture increased by 3.1% during this period, the effects of the adjustment varied significantly due to regional comparative advantages. Notably, foodstuff crop seeding areas dropped by 3.97% and foodstuff yield by 6.47% nationally, with visible drops in 22 provinces, leading to a warning that loosening vigilance on food security necessarily leads to a significant drop in China's food security.
