This study investigated the impact of agricultural type transformation on agricultural ecosystem services and human well-being in two villages in the Xi'an metropolitan area, China, using household surveys. From 2000 to 2017, Majia Village, focused on grain cultivation, saw its ecosystem service value decrease by 17.13%, while Huojian Village, focused on vegetable cultivation, experienced a 141.08% increase. Human well-being was 89% higher in Huojian Village, indicating that a shift from traditional grain cultivation to modern urban agriculture can enhance well-being, with agricultural net income being the most significant factor.

In Medan, Indonesia, a verticulture urban farming training program was implemented in Lorong Sidodadi, a densely populated area with limited green space (5.6% of the city). The program targeted non-productive housewives and involved five stages: preparation, socialization, training, mentoring, and evaluation. Participants reported positive responses, aesthetic, thermal, psychological, health, and economic benefits, and reduced vegetable purchases. However, the activity faced issues with rat pests and children's activities.

A hydroponic experiment in Indonesia tested the effect of plant growth regulators on water spinach (kangkung, Ipomoea aquatica) yield. Treatments included a control (AB-Mix), IAA (indole acetic acid) at 0.5 ppm, BAP (benzyl adenine purine) at 0.5 and 1.0 ppm, and combined IAA/BAP at 0.5/1.0 ppm, measuring leaf number, plant height, antioxidant content and water content. Morphological growth was most optimal under 0.5 ppm IAA, while 1.0 ppm BAP produced the shortest average plant height, fewest leaves and shortest root length. Chlorophyll testing showed 0.5 ppm IAA had the highest total chlorophyll content, averaging 9.55 μg/ml, and the authors conclude 0.5 ppm IAA had the most positive effect among the treatments tested.

A study of three family-owned peri-urban aquaculture operations downstream of Bangkok, Thailand — spanning extensive, semi-intensive and intensive practices — used micropollutant analysis, genetic markers and 16S rRNA amplicon sequencing to assess water quality against aquaculture standards. Canals draining Bangkok did not meet quality standards and were sources of faecal coliforms, Bacteroides, Prevotella, human E. coli, tetracycline-resistance genes and nitrogen entering the ponds, causing algae blooms. The aquacultures in turn discharged salinity and the herbicide diuron into the canals; diuron was detected in shrimp, though not at a level of concern to human health. The extensive aquaculture attenuated an estimated 20 population equivalents of nitrogen pollution and trillions of faecal coliform inputs per year.

The study tested a barrier strategy used by urban farmers in Indianapolis—layering wood chips between contaminated or low-quality background soil and healthy growing media—for protecting urban growing beds. Despite a limited sample, barriers appeared effective at separating contaminated soils from growing beds, and farming with barriers or in non-contaminated soil improved soil nutrients and physical characteristics, though phosphorus was very high in many beds, posing a potential risk to waterways.

A 12-month case-cohort study of 187 households in four communities of Ahmedabad, India, purposively selected by irrigation water type (groundwater, surface water, wastewater), with bimonthly self-reported health diaries and most-probable-number measurement of Escherichia coli in water. Mean E. coli concentrations per 100 mL were 3.04×10^4 (groundwater), 9.28×10^5 (surface water) and 4.02×10^9 (wastewater) — all exceeding international irrigation water standards. Diarrhoea incidence was 7.92 episodes per 1000 person-weeks in the groundwater area versus 13.1 (wastewater) and 13.4 (surface water), with a positive correlation between irrigation water quality and diarrhoea. Wastewater reuse is often promoted as a water-scarcity fix for urban agriculture; this study shows it carries a health cost borne by the farming households themselves.

This article examines the motivations and practices of organic terrace gardeners (OTGians) in Bengaluru, India, who grow food in private spaces. While OTGians successfully create a vibrant community driven by food safety and environmental concerns, their efforts are limited to the middle class due to class-specific concerns and production practices. The study highlights that urban gardening in this context remains an intervention primarily for the middle class.

A cohort study investigated the contribution of wastewater irrigation to in-household water contamination among urban farming households in Ahmedabad, India, within the context of WASH (Water, Sanitation, Hygiene). Drinking water samples from 204 households were collected four times over 12 months, and E. coli was quantified. Significant positive differences in water quality between point-of-source and point-of-use samples were identified in 78% of households. During the monsoon, the peak of contamination, only 6% of households had access to safe drinking water at the point-of-use. Wastewater irrigation showed an adverse effect on in-household water contamination, with an effect size larger than the mitigation effect of access to sanitation or personal hygiene.

A case study in peri-urban agricultural lands near Patranala, Bhopal, India, investigated the impact of over 50 years of untreated sewage water irrigation on soil properties. Findings showed higher concentrations of heavy metals in surface soils of sewage-irrigated fields, posing a major concern. Conversely, soil microbial population, enzymatic activities, and organic carbon content were also higher, indicating enhanced carbon sequestration.

Sandra Kurfürst · · Vietnam (Hanoi)

This chapter explores the production sites of vegetables perceived as clean and safe by Vietnamese consumers, specifically urban gardens in Hanoi and rural areas. It identifies a semantic shift in gardens from aesthetics to utility due to food anxiety and examines access to and social control over public and sacred spaces used for gardening. Urbanites also rely on personal rural-urban food supply networks for food safety, with the rural signifying safe foods based on its image as a place of intimate social relations and nature.

Against a background of high helminth-infection prevalence in Indonesia — which led the government to issue a 2017 ministerial regulation on preventing soil-transmitted helminths (STH) — this study investigated the potential presence of helminth eggs capable of causing STH infection in two urban agricultural areas in the northern and southern parts of Bandung City. Samples of inlet and plantation-area water, soil, and harvested water spinach from both areas were analyzed for helminth eggs using a modified Bailinger method, and egg counts of 1–119 eggs/L were found across the water, soil, and vegetable samples. The results confirmed that irrigation water in both areas was contaminated with feces, with average fecal coliform counts exceeding the allowable value for irrigation water under Indonesia's Grade 4 water-quality criteria; variation in egg counts was attributed to environmental conditions such as temperature, humidity, and soil type. Helminth-egg levels in the irrigation water and land samples exceeded the values recommended by the WHO's 2006 guidelines for safe use of wastewater in agriculture, which the study links to an increased risk of helminth infection among consumers, agricultural workers, and residents near the farmland.
