Researchers sampled 145 items — 88 raw vegetables, 27 water and 30 soil samples — from rooftop and surface gardens in urban Dhaka North and Dhaka South City Corporations and peri-urban Gazipur City Corporation, Bangladesh, testing for Escherichia coli by culture, biochemical tests and malB-gene PCR. Overall prevalence was 58.62% (95% CI 50.48–66.31): 80.0% in Dhaka South, 44.70% in Dhaka North and 76.7% in Gazipur. In Dhaka, surface gardens were more contaminated (70.83%) than rooftop gardens (46.57%), while in Gazipur rooftop gardens were worse (93.33% vs 60.0%). Of 54 randomly selected isolates, 100% were resistant to ampicillin, with resistance to ciprofloxacin (25.92%), tetracycline (14.81%) and imipenem (9.25%); 14.81% were multidrug resistant and 81.48% carried blaTEM. Home-grown urban vegetables are not automatically hygienically safe.

A cross-sectional survey conducted from December 2022 to June 2023 at three randomly selected sites in the Kathmandu Valley, Nepal (Kathmandu, Lalitpur and Bhaktapur), comparing 115 residents who practise urban agriculture with 115 who do not (n=230), using the SF-12 health survey, the Perceived Stress Scale and the Satisfaction with Life Scale. Participants engaged in urban agriculture reported significantly lower perceived stress and significantly higher life satisfaction. However, the two groups differed significantly in gender, ethnicity, occupation, marital status, education and home ownership (p<0.05), and the cross-sectional design cannot separate an effect of gardening from selection into gardening by better-off residents.

This systematic review synthesizes peer-reviewed literature on various forms of green infrastructure and their mechanisms for mitigating Urban Heat Island (UHI) effects, and the function of urban green spaces (UGS) in reducing the impact of UHI. Important mechanisms, including shade, evapotranspiration, albedo change, and ventilation, were investigated in connection with urban parks, green roofs, street trees, vertical greenery systems, and community gardens. The findings show that green areas, including parks, green roofs, and street trees, can lower air and surface temperatures by as much as 5 °C. However, the efficiency of cooling varies depending on plant density and spatial distribution.

A transdisciplinary research project investigated reusing treated kitchen wastewater for irrigating edible vegetable production in households. The project developed a prototype with an engineered biological filter to reuse dishwasher wastewater for growing vegetables and ornamental plants for domestic use. This approach aims to reduce water and fertilizer consumption, enabling the production of healthy, safe, and local food.

This study assessed whether mixed residential-agricultural land use can sustain urban agriculture and if residential landowners in rapidly urbanizing Ghanaian cities are willing to allocate plot space to agriculture. Researchers surveyed 280 landowners across four peri-urban settlements in Kumasi and used geospatial data to estimate available residential space. Nearly four out of five landowners were willing to cede their backyards for micro-farming, with geospatial estimates identifying 75.65 hectares of available residential area across the settlements, equivalent to approximately 0.03 ha per plot (about 23% of an average 0.13 ha plot). These findings suggest the potential of backyard micro-farming as a strategy for sustaining urban agriculture.

This research investigated the correlation between KWT (women farmer groups) participation and the sustainability of the KRL Katulampa waste management program, which incorporates urban farming using processed waste. A census of all KWT Berkah members was conducted using questionnaires and in-depth interviews. The study found a correlation between KWT community participation and the program's sustainability, but noted that urban farming needs to be complemented by other activities to ensure significant economic benefits beyond social advantages.

A year-round eddy covariance and soil chamber measurement in an urban allotment garden in southern Finland showed it functioned as a net CO₂ source (0.69 kg m⁻² yr⁻¹) despite 77% vegetation cover. High respiratory emissions (4.7 kg m⁻² yr⁻¹) exceeded photosynthetic uptake (4.0 kg m⁻² yr⁻¹), likely due to elevated soil organic carbon (13.4 ± 8.7%) and high soil C:N ratio from management amendments. These findings challenge assumptions about urban gardens as inherent carbon sinks and suggest carbon-smart management practices are needed.

A community service program at PKBM Cahaya Rejeki involved 20 students in hands-on workshops to build vertical gardens using recycled materials. The program aimed to improve urban youth's understanding of vertical agriculture in non-formal settings. A Wilcoxon Matched-Pairs Signed-Rank Test showed a statistically significant increase in students' agricultural knowledge, supported by field observations of increased enthusiasm and confidence.

This descriptive review study examined whether urban agriculture aligns with SDG 12 (Responsible Consumption and Production) of Agenda 2030 and generates social benefits for producers, analyzing articles published from 2019 to 2022 from Scielo, Scopus, and Web of Science databases. The results showed that urban agriculture aligns with SDG 12, generating ten main social benefits, including improved quality of life, social inclusion, food security, and promotion of mental and physical health.

Chua Siu Ting, Hazreena Hussein · Journal of Surveying Construction & Property · Malaysia (Port Dickson)

This study explored residents' perceptions of social spaces in Port Dickson, Malaysia, during the COVID-19 pandemic, using a mixed-method approach combining photographic documentation and a questionnaire survey. The majority of respondents experienced significant stress during the pandemic due to anxiety, job loss, and livelihood challenges, emphasizing the importance of effective space allocation and varied options within residential neighborhoods. These findings imply that strategically designed social spaces and zoning practices are key to developing self-sufficient communities in residential areas.

This article discusses urban agriculture, noting that the decline of grocery stores in inner cities and projected vulnerabilities in megacities outside the global West suggest distinct moral imperatives. It contrasts urban agriculture with rural resilience and sustainable intensification, highlighting its focus on consumption and present needs. The article describes two urban agriculture archetypes: one embracing high-tech solutions and another emphasizing local solidarities and urban-based control over the food system.

This study evaluated the potential of rooftop and wall-based urban agriculture to enhance food security in Gasabo District, Kigali, Rwanda. It used GIS and remote sensing to map suitable spaces and assessed 400 household heads using the Household Food Insecurity Access Scale (HFIAS). Findings showed that 41.5% of households experienced moderate to severe food insecurity, and approximately 32% of rooftops and walls were structurally appropriate for urban agriculture. While 57.8% of households expressed willingness to adopt rooftop or wall gardening, 67.4% cited structural and financial constraints.

This systematic literature review analyzed 58 empirical studies on nature-based instruction (NBI) in science education from 2021-2025, focusing on formal and school-linked learning settings. Most studies used qualitative or mixed-methods designs, with outcomes primarily in affective and cognitive domains. Recurring challenges included limited causal designs, short follow-up periods, and inconsistent implementation reporting.

This chapter examines agroecology as a sustainable production paradigm for the horticultural sector, facing challenges like climate change and resource depletion. It reviews the conceptual foundations of agroecology, its application to horticulture, and advances in agroecological practices. Case studies, such as peri-urban horticulture in Argentina, illustrate its promise, but note that a full transition remains incomplete.

This research defines urban voids as idle, unused, or partly used urban lands that public agencies fail to utilize to their maximum capacity. It proposes that these urban voids can serve as valuable resources in sustainable planning by creating green infrastructure, fostering civic engagement, and enhancing biodiversity. Converting these spaces into parks or community gardens can encourage social interaction and improve urban living quality.
