In Dar es Salaam, Tanzania, the utilization of faecal sludge derived compost (FSDC) by urban farmers remains limited due to farmers' prejudice and hesitance. This study investigated factors influencing FSDC acceptance through a cross-sectional survey of 76 urban farmers. Results indicated that garden location in communal areas, income generation as the primary farming purpose, and accessibility of soil inputs were significantly associated with FSDC acceptance. Farmers' awareness and experience also played important roles.

This systematic qualitative literature review, following the PRISMA 2020 protocol, analyzed 20 documents to understand how recent academic production articulates education, work, and sustainability within Youth and Adult Education (EJA), focusing on school gardens. The literature recognizes gardens as a social technology that integrates ecological knowledge, cooperative practices, autonomy-building, and income generation, especially in socioeconomically vulnerable contexts. Gardens are concluded to be a powerful pedagogical device for EJA, contributing to critical environmental education, popular economy, and emancipatory practices.

An online survey of 250 urban residents across various regions of Malaysia investigated factors influencing the adoption of hydroponic farming. Findings indicate that attitude, hydroponic compatibility, and perceived trust significantly influence adoption intentions, and intention strongly influences actual adoption. However, performance expectancy, effort expectancy, and social influence did not significantly impact adoption intentions.

This study evaluated vertical farming (VF) through the resource nexus (RN) lens, emphasizing the interdependencies among energy, water, land, and materials. While VF offers advantages such as space efficiency, water conservation, and climate resilience, it was found to entail high energy demands, material dependencies, and economic feasibility challenges. An overview of these synergies and constraints helps identify mitigation strategies like circular water systems and hybrid renewable energy solutions.

A study in Malaysia assessed the perceived restorativeness of tropical urban green spaces (UGSs) using 120 environmental stimuli and 87 participants. Nature and mixed urban-nature scenes were generally rated as more restorative than urban scenes. In the visual-only modality, mixed urban-nature scenes were perceived as more restorative than nature scenes, but no significant differences were found in audio-only and bimodal modalities.

This special issue presents an innovative framework for sustainable land use, leveraging synergies between plants, soils, and societies to address global environmental crises and food insecurity. It notes that human activities, including land clearing for agriculture, rapid urban sprawl, and heavy use of chemical inputs, have pushed biogeochemical cycles of carbon, nitrogen, and phosphorus beyond their safe operating limits. The collection of papers collectively emphasizes the need for a fundamental shift in managing plant, soil, microbes, and human systems as interdependent components.

This study quantified emissions and toxicological consequences of a large-scale tire fire in an urban ecosystem by analyzing soil samples from the fireground and surrounding urban allotment gardens for zinc and 16 polycyclic aromatic hydrocarbons (PAHs). Soil at the fire site showed severe contamination with PAHs (Σ PAHs: 148.9 mg/kg), and the cumulative Incremental Lifetime Cancer Risk (ILCR) for children reached 9.7 × 10−4, exceeding the regulatory benchmark. Elevated risk levels persisted at distal residential sites, indicating long-term environmental contamination and persistent terrestrial health hazards.

This study provides an eco-critical analysis of Eleanor Catton’s novel "Birnam Wood," exploring the entanglement of environmental activism, capitalist expansion, and identity formation. While the novel depicts conflicts between activist collectivism and corporate techno-capitalism through guerrilla gardening and land commodification, the study argues that its allegorical structure and reliance on familiar ideological binaries may constrain its capacity to generate radically new ecological insight. The research ultimately raises questions about the limits of literary representation in envisioning transformative environmental futures.

Tracks how DDT, a legacy contaminant, restructures the soil microbiome of an urban garden in Istanbul across a 15-day microcosm experiment. Rather than broad diversity loss, Shannon diversity rose steadily as sensitive taxa were suppressed; Rhodococcus, Kribbella and Nitrospira increased while Pedomicrobium and Lysobacter declined. Inferred functions shifted away from aromatic amino-acid and fatty-acid metabolism and towards degradation of chlorinated aromatics, redox homeostasis and stress response — a successional move to a stress-resilient, potentially degradative community.

A study of Tanzania combining a systematic literature review with a comparative analysis of rural and urban food-production systems, examining how patriarchal land tenure, unpaid care work, and insecure urban farming arrangements restrict women's participation in higher-value agricultural production. The findings show that technical support alone is insufficient unless paired with structural reforms strengthening women's land rights, labour-saving technologies, and changes to unequal gender norms. Based on this, the study proposes a Gender-Transformative Approach linking legal reform, institutional support, technological innovation, and community-level change.

This systematic review, pre-registered with PROSPERO (CRD420251250712) and conducted following PRISMA guidelines, synthesized global evidence on the effects of horticulture-based interventions (HBIs) on student well-being. It searched PubMed, Web of Science, MEDLINE, EMBASE, and APA PsycInfo from inception to June 30, 2025, and included 15 studies (more than 2,000 students aged 5-18) from South Korea (8), Taiwan (3), Mainland China (1), Hong Kong (1), Italy (1), and the United States (1). Results showed HBIs have the potential to enhance emotional/psychological well-being (e.g., stress reduction, mood improvement), social well-being (e.g., peer relations, social skills), cognitive and educational benefits (e.g., attention, academic attitudes), and physical and overall health benefits (e.g., physical activity, quality of life). The review states that future randomized controlled trials with diverse populations are needed to address limitations such as small sample sizes and geographic bias.

A conceptual paper on territorial food governance argues that territorial food networks function as governance structures rather than mere exchange channels, sustained day to day by women's labor, knowledge transmission and coordination — work typically classified as informal or subsistence-based and denied political recognition. It contends these networks are structurally low-carbon because of their socio-productive organization rather than any explicit climate strategy, and frames women's role as collective, local governance leadership rather than individual participation.

This conceptual paper proposes the Urban Agriculture Digital Twin (UA-DT), a four-layer cyber-physical framework combining IoT sensing, cloud infrastructure and hybrid mechanistic/AI models for real-time monitoring and city-scale food-system simulation, with logical feasibility demonstrated through an illustrative software simulation (Eclipse Ditto, Azure IoT, Python) for a community rooftop garden. The paper cites benchmark ranges — 20–40% water savings, 15–25% fertilizer reduction, up to 30% post-harvest loss reduction, and 3–7 day early-warning lead time — as literature-derived projections that a fully validated UA-DT deployment would be expected to approach, explicitly noting these are not empirical findings of this study.

A book chapter reviewing Singapore's changing urban agriculture landscape and recent progress toward its "30-by-30" goal of 30% food self-sufficiency by 2030, discussing land constraints, high production costs, and resource limitations. It examines building-integrated agriculture (BIA)—using rooftops, façades and balconies for food production—as a potential way to raise self-sufficiency through simulation, but concludes that practical issues including regulatory concerns and infrastructure limitations must be addressed before BIA can be implemented at scale.

A synthesis paper on the largely unexplored role of domestic gardens in influencing local air quality. While gardens are widely recognized for cultural and health benefits, particularly mental well-being and everyday contact with nature, the paper states few studies have examined air quality dynamics within residential garden settings. It notes that general urban green infrastructure research suggests vegetation structure, plant traits, and spatial configuration shape pollutant capture, but these findings have not been tested in domestic gardens, where microclimates and spatial constraints differ markedly. Evidence from food-growing gardens and allotments further suggests edible crops cultivated near roads may accumulate airborne pollutants, particularly metals, underscoring the need for research on exposure pathways and allotment locations. The paper identifies a significant gap in current green infrastructure and air-pollution research: the lack of empirical evidence on how domestic gardens function as socio-ecological systems with implications for air-quality regulation.

This study analyses research trends at the intersection of nature-based solutions (NbS), food systems and the SDGs using a multi-method approach combining a systematic literature review, betweenness centrality analysis and fuzzy logic. It identifies growing interest in climate change and urban agriculture and expanding European-led international collaboration, and names five major trends -- land-water-food nexus, urban farming and green infrastructure, governance and policy, community readiness and indigenous knowledge, and soil health and regenerative techniques -- finding the governance/policy trend has the highest betweenness centrality for bridging SDGs and the community-readiness trend shows the strongest convergence of social, urban and ecological goals.

This study developed a machine learning-based leaf-disease detection system to help rooftop gardeners and small-scale growers, aiming to address plant-disease spread and delayed diagnosis that leads many gardeners to abandon increasingly popular rooftop gardening in space-limited urban areas. Using image segmentation as a preprocessing step followed by a classification model, and trained and tested on leaf images from five commonly cultivated species -- guava, jamun, lemon, mango and pomegranate -- the system achieved an overall accuracy of 1.00, with lemon and mango disease classification reaching accuracies of 0.995 and 0.991 respectively and F1-scores exceeding 0.88.
