This ethnographic research, based on two months of fieldwork in Beijing and Shanghai, investigated alternative food networks in China, including organic farms, farmers' markets, and garden plot rentals. The study argues that these networks exhibit complex and contradictory characteristics, not neatly aligning with either alternative or conventional food systems. The practice of alternativeness is presented as a pragmatic response to food safety uncertainty and declining social trust, rather than an escape from capitalism or a purely transformative agenda.

Jae-Youl Lee · 대한지리학회지 · South Korea (Seoul)

This article examines the concept of 'community' in Seoul's community garden program, comparing how ordinary citizens and civil society activists interpret and practice it. Empirical findings suggest a contestation over community, with ordinary citizens prioritizing place-based experiences and activists viewing community gardens as a governmental technology. A gap between ordinary practical achievements and civic activism poses a potential danger to urban community policy.

Masdjidin Siregar · Jurnal Agro Ekonomi · Indonesia (Jakarta)

This paper describes intensive peri-urban leafy vegetable agriculture in Jakarta, which utilizes idle land and provides employment and income for rural migrants. However, the prospect of this agriculture is unclear because it uses non-agricultural land that will eventually be developed. The study concludes that government assistance in credit, extension, and research is needed, and alternative lands for cultivators must be found.

A study of the pink hibiscus mealybug (Maconellicoccus hirsutus), documented as a growing urban pest in the agricultural fields of Vadodara, India. Regular visits to agricultural fields and community gardens over two years (April 2013-April 2015) tracked the pest's morphology, biology, distribution, and relation to biotic and abiotic factors, along with damage type and extent on different host plants. Major infestation occurred on Annona squamosa, followed by significant infestation on Hibiscus rosa-sinensis and Gossypium hirsutum (cotton), with adult females and nymphs as the main infesting stages and damage peaking in the winter months of November to February. The study also documented a mealybug-ant mutualistic association and noted that the prevailing use of chemical pesticides in the city is a probable reason for the growing mealybug population.

Mercury is a highly toxic and hazardous heavy metal, and bacteria able to live in mercury-contaminated habitats — mercury-resistant bacteria, including Azotobacter — are known to exist. This study aimed to obtain superior Azotobacter isolates resistant to mercuric chloride (HgCl2) from land at the ITS (Institut Teknologi Sepuluh Nopember) Eco Urban Farming site — land where mercury contamination was present — and to determine mercury reductase enzyme activity as a bioreductant converting Hg2+ to Hg0. Isolation used selective Azotobacter agar media, resistance was tested by a slant-agar streak method containing HgCl2, and mercury reductase activity was analyzed using the MRA method and spectrophotometry at 340 nm. Ten HgCl2-resistant Azotobacter isolates were obtained; isolates A5 and A9 tolerated 10 mg/L HgCl2 with optimal growth and relatively high mercury reductase activity, showing a reduction capacity of ≥3 mg/L and a reduction efficiency above 70% at an HgCl2 concentration of 5 mg/L.

Arti Bhatia, Shivdhar Singh, Amit Kumar · Water Environment Research · India (Delhi)

A study in Delhi, India, investigated heavy metal contamination (cadmium, lead, zinc, copper) in irrigation water, soil, and vegetables from four peri-urban and one wholesale site. Most samples from peri-urban areas exceeded safe limits for lead and cadmium. Vegetables from the wholesale market showed only higher lead concentrations. Among peri-urban vegetables, only okra exceeded the safe limit for cadmium, while several wholesale vegetables (potato, coriander, chilies, pea, carrot) exceeded the limit for lead regarding health risk.

宋志军, 刘黎明 · Acta Scientiarum Naturalium Universitatis Sunyatseni · China

Chinese urban agriculture has developed against a backdrop of multifunctionality, urbanization, industrialization, and non-agriculturalization. Since the reform and opening-up, the development of non-agricultural functions has complemented and advanced the broad modernization of urban agriculture, while simultaneously inhibiting, delaying, and destroying narrow modernization. This has led to a "reverse modernization" phenomenon in the spatial pattern of urban agriculture, characterized by changes spatially "opposite" to narrow agricultural modernization. China's current urban agriculture exhibits an overall spatial state of "reverse modernization" with various agricultural forms interspersed.

Jingjing Zhang, Jingshuang Liu, Rui Yu, Qiang Liu, Yang Wang · Human and Ecological Risk Assessment An International Journal · China (Jilin City)

This study analyzed 50 surface soil samples from urban vegetable fields in Jilin City, China, for thirteen organochlorine pesticides (OCPs). Based on soil quality standards, DDTs and chlordanes were categorized as light pollution, while HCHs showed no pollution for most samples. The study concluded that despite the presence of various OCPs residues, the soils are still safe and suitable for agricultural production.

Qing Guo · · China (Dalian)

This paper, based on the China urban agriculture development report 2013 and a SWOT analysis, studied the development of urban modern agriculture in Dalian. The study found that the agricultural industrial structure, shopping basket program, agricultural management system, land circulation, and agricultural information technology have restricted the development of Dalian's urban modern agriculture.

Kyung-chan Min, Jee-young Kim, yong-hoon Son · Institutional Repositories DataBase (IRDB) · South Korea

A study in Gwanak-gu, Seoul, South Korea, investigated 45 spontaneous agricultural lands, primarily around Mt. Gwanak, which often present risks like disaster, pollution, and landscape degradation. Using GIS, satellite images, field surveys, and interviews, the study classified these lands into six types. Three types were well-managed, while three types were in poor condition, indicating governance challenges. The research discusses the causes of these conditions and explores the potential for these lands to become community open spaces.

Gunwon Lee, Yunnam Jeong, Seongkyun Ji, Seiyong Kim · Journal of the Korea Academia-Industrial cooperation Society · South Korea

This study aimed to improve Biotope Area Ratio (BAR) systems to address the increasing demand for urban agriculture, particularly in residential complexes where architectural and urban planning responses are lacking. It found that existing BAR systems are limited for crop cultivation because they only consider vegetation. The research proposes expanding BAR systems to include plant growth capacity factors, such as daylight, planting interval, area, and soil depth, to better accommodate urban agriculture demands.

Zulfadhli Nasution · · Indonesia (Jakarta, Bandung, Bogor)

This study investigated the relationship between urban farming communities and food sovereignty in Jakarta, Bandung, and Bogor, Indonesia. The findings suggest that the discourse of food sovereignty has not been exposed to urban farming communities. This is attributed to urban farming having different historical roots and social and political characteristics compared to the food sovereignty movement.

Jin Hee Kim, Jin I. Yun · Korean Journal of Agricultural and Forest Meteorology · South Korea (Seoul)

This study evaluated daily temperatures for June-September from 2041-2070 in Seoul, projected by the RCP8.5 climate scenario, to understand climate departure implications for urban agriculture. Analysis of climate extremes and their effects on hot pepper growth revealed that while mean temperatures might depart after 2040, extreme events like heat waves and tropical nights already exceed past variability. Applying scenario data to hot pepper cultivation showed that planting and harvest dates are expected to deviate, and the maximum cultivation duration has already deviated from past variability.

This comparative study of urban agriculture in Mumbai, India, and New York City, USA, utilized in-depth interviews with urban farmers and secondary research. The research revealed that farms and gardens in lower-income areas in both cities had access to significantly fewer resources than their counterparts in wealthier areas. Additionally, both movements struggled to form networks across socioeconomic divides.

徐晶, 吴聪 · 中国土地 · China (Wuhan)

This paper analyzes the practice and problems of "multi-plan integration" in Wuhu Street, Huangpi District, Wuhan City, a rapidly urbanizing area dominated by modern urban agriculture. Wuhu Street faces issues such as the disorderly sprawl of construction land and low land use efficiency. The study proposes targeted policy recommendations based on these findings.

Zulfadhli Nasution · · Indonesia (Jakarta)

A case study in Jakarta, Bandung, and Bogor, Indonesia, examined the engagement between urban farming communities and food sovereignty. Findings indicate that the food sovereignty discourse has not significantly exposed urban farming communities due to differing historical backgrounds and social/political views between urban farming and rural peasantry-based movements. The study suggests prerequisites for strengthening food sovereignty among urban food advocates, including building consumer consciousness and urban-rural solidarity.

Yang Feng-x · · China

A field investigation with detailed records examined the safety of park green spaces in major parks and community gardens in Shenzhen and Hong Kong, China. Measured against a "people-oriented" guiding principle and a "select the auspicious, avoid the inauspicious" principle, the study identifies several safety hazards and unreasonable plant arrangements present in these park green spaces as irrational, and proposes methods and countermeasures to address them.
