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.

A. C. Egun · Journal of Agricultural Sciences · Global

This paper examined the competencies needed by Agricultural Science teachers in urban areas for effective institutional preparation. Teachers identified 24 competencies for urban agriculture teaching but expressed deficiency in 19 competencies (79.17%). The curricular implication is to include basic Humanities subjects like Geography, Economics, and Commerce in Agricultural Science teacher programs and to effectively implement field trips to strengthen the relationship between theory and practice.

Megan Sheridan · University of Minnesota Digital Conservancy (University of Minnesota) · United States (Minneapolis)

This project aimed to facilitate the creation of a commercial urban farm in the Seward neighborhood of Minneapolis. Goals included developing a business plan for an economically viable urban farm. The project found that economic viability without foundation grants is challenging, and site control is key.

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.

Eva Collins, Kate Kearins · Academy of Management Learning and Education · New Zealand (Auckland)

A sustainability instructor took a graduate class to an eco-village near Auckland, New Zealand, where students observed off-grid homes and community gardens. While New Zealand students were inspired by the alternative lifestyle, two international students from China and Tajikistan expressed that this lifestyle was how they lived at home and they did not wish to live that way, preferring the New Zealand lifestyle. This indicates a limited appeal of the eco-village model to some international students.

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.

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.

Pay Drechsel, Liqa Raschid-Sally, Robert Clement Abaidoo · · Ghana (Accra)

Urbanization in West Africa has led to most domestic wastewater contaminating surface water sources. In Accra, Ghana, vegetables on urban markets are highly contaminated, with about 200,000 urban dwellers consuming street food containing raw vegetables from these sources daily. This research explores on-farm risk mitigation options, finding potential to significantly reduce helminth egg counts and bacterial contamination through improved washing practices.

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.

XU Hua-me · Technoeconomics & Management Research · China

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.

Abegunde A. A, Emmanuel Olufemi Omisore, O. F. Oluodo, D O Olaleye · African Journal of Agricultural Research · Nigeria (Lagos)

A study in the Eti-Osa local government area of Lagos, Nigeria, investigated the socio-spatial effects of urban horticultural gardens. Of 75 identified gardens, 63 managers were interviewed, revealing that 79.4% of gardens were profit-oriented. Gardens had inadequate setbacks (mean 1.45 m) from roads, leading to off-street parking and traffic congestion. Only 20% of horticulturists aimed to improve urban aesthetics, indicating a need for urban planners to educate them to prioritize urban aesthetics over economic gain.

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.

Justin Stoler, John R. Weeks, Arthur Getis, Allan G. Hill · American Journal of Tropical Medicine and Hygiene · Ghana (Accra)

A 2003 study in Accra, Ghana, surveyed 3,164 women to examine the relationship between self-reported malaria and proximity to urban agriculture (UA). The odds of self-reported malaria were significantly higher for women living within 1 km of UA compared to those living near an irrigation source, with the association disappearing beyond this distance. Malaria prevalence was often elevated in communities within 1 km of UA, even with more favorable socioeconomic characteristics.

Eveline Klinkenberg, Philip J. McCall, Michael D. Wilson, Felix P. Amerasinghe, Martin J. Donnelly · Malaria Journal · Ghana

This study investigated the impact of urban agriculture on malaria transmission risk in Accra, Ghana, through larval and adult mosquito surveys. It found that Anopheles spp. and Culex quinquefasciatus outdoor biting rates were three and four times higher, respectively, in areas around agricultural sites compared to areas far from agriculture. The annual Entomological Inoculation Rate (EIR) was also higher in agricultural areas (19.2) than non-agricultural areas (6.6), suggesting that urban agricultural areas may increase malaria transmission risk by providing resting sites for adult mosquitoes.

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.

Anselm A. Enete, Anthonia Ifeyinwa Achike · Outlook on Agriculture · Nigeria (Ohafia)

A study comparing rural and urban farmers in Ohafia, southeast Nigeria, found that while urban farmers used significantly more purchased inputs than rural farmers, their output was significantly lower. This was attributed to urban farmers being poor and undercapitalized, preventing them from using adequate purchased inputs to maintain soil nutrients. The findings suggest that for urban agriculture to address urban food insecurity, the urban poor require sufficient financial empowerment.

Friedhelm Streiffeler, Elsamawal Khalil Makki, Ali Ayoub · Econstor (Econstor) · Sudan (Khartoum)

This research in Greater Khartoum, Sudan, investigated urban and peri-urban agriculture as a livelihood strategy for internally displaced persons. While urban agriculture significantly reduces absolute poverty, its implementation faces many problems due to natural, economic, and social differences in the new environment, resulting in a low degree of agricultural development. Migrants with smaller fields and lower agricultural development showed a greater desire to return to their homeland, and social integration also influenced the decision to stay or return.

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.

M. B. David · African Affairs · Kenya

This study on urban agriculture in the Kenyan town of Nakuru illustrates health and environmental problems associated with keeping livestock in urban areas, the small size of plots cultivated, and the dependence of urban households on rural sources of food. These findings were observed in the context of economic hardships occasioned by structural adjustment programmes since the 1980s.

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.

Barbara Matthys, Penelope Vounatsou, Giovanna Raso, Andres B. Tschannen, EMMANUEL GBEDE BECKET, Laura Gosoniu, Guéladio Cissé, Marcel Tanner, ELIÉZER K. N’GORAN, Jürg Utzinger · American Journal of Tropical Medicine and Hygiene · Côte d'Ivoire

This study investigated malaria risk factors in urban farming communities in a medium-sized town in Côte d'Ivoire, conducting two cross-sectional surveys among 112 households across six agricultural zones. The overall prevalence of Plasmodium falciparum was 32.1%. Findings indicate that specific crop systems and agricultural practices may increase the risk of malaria in urban settings of tropical Africa.

Fabrício de Araújo Pedron, Ricardo Simão Diniz Dalmolin, Antônio Carlos de Azevedo, Márcio Ramos Botelho, Alessandro Samuel‐Rosa · Ciência Rural · Brazil (Santa Maria)

This study analyzed the spatial and temporal dynamics of land occupation in urban areas of Santa Maria, RS, Brazil, and determined land use conflicts using data from 1975 to 2002. Urban land use increased from 9% in 1975 to 33% in 2002. Land use conflicts increased from 19% in 1975 to 37% in 1995, then decreased to 33% in 2002. The main problems of improper land use are related to the fragility of geological material and soil resources for use in construction and urban agriculture.

Lily Kiminami, Akira Kiminami · Studies in Regional Science · Japan

Urban agriculture in Japan faces problems such as farmland reduction, farmer aging, expansion of abandoned cultivated land, and environmental pollution from livestock waste or agricultural chemicals. Urban agriculture can contribute to improving urban quality of life by supplying agricultural goods, creating landscapes, ensuring land conservation, and providing environmental benefits like biodiversity conservation. However, these issues pose challenges to the economic viability of urban agriculture.

Fabrício de Araújo Pedron, Ricardo Simão Diniz Dalmolin, Antônio Carlos de Azevedo, Everton Luís Poelking, Pablo Miguel · Ciência Rural · Brazil (Santa Maria)

This study conducted an environmental diagnosis in urban areas of Santa Maria, Brazil, using the Urban Land Use Potential Assessment System (SAPUT) to identify land use conflicts. Remote sensing and geoprocessing techniques were employed. The identified problems of improper land use are related to the fragility of geological material and soil resources, with up to 33% of the area being used beyond its potential due to inadequate use for construction and urban agriculture.
