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.

This paper evaluates the evolving role of Green Belt policy in England, arguing that both the designation and the land it protects are increasingly critical to addressing environmental, climate and public health challenges. It defines the extent and characteristics of Green Belt and other "countryside around towns" land, showing that these areas prevent urban sprawl, support nature recovery, provide public access to green space and sustain cultural landscapes, while highlighting mounting pressures including housing demand, weakened planning controls, losses in farming capacity and newly introduced "grey belt" policy reforms, and recommending measures such as reinstating strategic planning through Spatial Development Strategies, adopting a brownfield-first approach, prioritising environmental land management, and considering new Green Belt designations or expanded National Landscape protections.

A comparative hydrological study, based on extreme-value statistics, of the Caupicho ravine south of Quito, an urban-agricultural transition zone. The most significant flood events correspond to 50-100 year return periods, but historical records show that the Lucha de los Pobres Baja neighborhood experiences flooding roughly every five years, causing economic losses and undermining social resilience. Based on vulnerability mapping and scenario modeling, the study identifies earthen ponds reinforced with totora (Schoenoplectus californicus) as biomaterial as a key input for flood-risk management and territorial planning, proposing the delimitation of evacuation and rescue areas.

A documentary literature study examined urban agriculture in Gurupi, Tocantins, Brazil, where 288 productive units exist despite the municipal master plan and local legislation not explicitly addressing the practice, focusing on the need for municipal regulation. Drawing on federal, state, and municipal legislation, academic studies, territorial diagnostics, and empirical survey data from Primo et al. (2014), the study found that urban agriculture holds socio-environmental, food, and community relevance but faces a lack of technical assistance, legal insecurity, and scarce institutional support.

A paper examines 'healthfields'—former brownfields, land whose contamination history impedes redevelopment and which in the US are disproportionately concentrated in underserved communities of color linked to poor health outcomes—redeveloped through participatory approaches to provide health benefits such as recreational parks, community gardens, and health care centers. Noting that healthfields are difficult to realize because local governments often see them as low-return investments offering little tax-base benefit relative to operation and maintenance costs, the paper describes the history and outcomes of a university-community partnership redevelopment project that catalyzed additional development including attainable housing, evaluating its public health contribution using an established land-reuse model for safely cleaning up and reusing contaminated brownfields.

A community service (PkM) program in Gulon, RT 01/RW 19, Jebres sub-district, Surakarta, Indonesia, worked with residents facing limited yard space and low use of household space for food self-sufficiency, aiming to raise knowledge, attitudes and skills in fruit and ornamental plant urban farming. Methods comprised outreach sessions, hands-on planting training and participatory community mentoring. As a result, resident participation in yard use increased, with 17 participating households beginning to independently grow fruit and ornamental plants, and new planting habits formed that support household food resilience and environmental quality.

A 2026 community service program based at RPTRA Payung Tunas Teratai in Cipayung sub-district, Indonesia, sought to build resident capacity through technology-based urban farming. Key problems addressed were limited knowledge of modern agricultural technology, low urban farming literacy, and underuse of the RPTRA's function as an education center. Participatory training — including material delivery, hands-on hydroponic and aeroponic practice, group discussion and ongoing mentoring — improved participants' understanding and skills in urban farming techniques, with a harvest success rate exceeding 80% in the first cycle. The Edufarm area was put to use as a community learning center, and a small farmer group was formed to support the program's continuation.

This chapter examines how community-supported agriculture (CSA) empowers Black farmers through innovations and community partnerships in Appalachia and nearby regions of the United States (2026). It traces CSA's roots to Booker T. Whatley's 1960s clientele membership clubs, explaining how shares, upfront payments and risk-sharing stabilize farm income while improving local access to fresh food. Case studies include Swanson Family Farm's buyer's club near Atlanta, Southside Community Farm's BIPOC-centered urban model in Asheville, and Cleav's Family Market's traditional Kentucky CSA. The chapter also addresses persistent barriers — limited resources, systemic discrimination and land access — and highlights the support networks and policy impacts shaping CSA success for Black-led food equity efforts.

Arguing that existing "Water-Energy-Food" nexus thinking fails to capture the complexity of urban nature-based solutions such as urban gardens, this perspective paper proposes a "Food-Water-Soil (FWS) nexus" framework analyzed through the dual lens of ecosystem services (ES) and ecosystem disservices (EDS), which arise together with ES rather than as mere byproducts. It positions ES and EDS as the core mediating functions that define a system's potential and limits, and conceptualizes soil as a "living infrastructure" whose management-driven dynamic properties govern the trade-offs and synergies between food production and water dynamics.

A 2024 systematic survey of 217 urban farming households in Yogyakarta City, Indonesia, used Stata 19 for hypothesis testing and SPSS 27 for descriptive statistics, running a multiple linear regression of net urban farming income against 22 variables covering sociodemographics, farm structure, input management, biotic stress and institutional support (R2 = 0.7448). Eleven variables had a significant effect, with farm size the most favorable factor, followed by financial support, seed subsidies and technical aid; gender and family size also showed positive effects. Crop type correlated negatively with income, and biotic stress — particularly pest type and severity — substantially reduced income, while training and market access were not statistically significant.

A study in Makassar City, Indonesia, evaluated the multidimensional sustainability of urban agriculture (UA) through expert discussions and semi-structured interviews with 23 purposively selected stakeholders including academics, practitioners, urban planners, legislators and government officials. A Multidimensional Scaling (MDS) approach compared sustainability indices from two previous studies, supplemented by prospective and interdependence analyses to identify key leverage factors. Results showed the overall sustainability status of UA in Makassar during 2016-2020 remained "less sustainable," with a multidimensional sustainability index of 43.02%; the ecological (51.84%) and technological (65.09%) dimensions improved to moderately sustainable status, while the economic (46.15%), social (49.81%) and institutional (39.20%) dimensions showed declining sustainability performance. The study proposes three policy directions: strengthening UA planning and management systems, improving institutional coordination among stakeholders, and expanding UA's socio-economic and environmental functions.

In the Santhal Pargana region of Jharkhand, India (the districts of Dumka, Godda, Sahebganj, Pakur, Jamtara and Deoghar), community surveys, field walks and ethnobotanical interviews with Santhal and other tribal communities documented 54 species of wild edible and medicinal plants. Each species is recorded with local names in Santali and Hindi, plant parts used and field observation notes, and classified as wild food, medicinal, or both. The work was carried out under the Wild Food Forests Tribal in Jharkhand project, supported by The Pollination Project (USA), and states that the region's ethnobotanical diversity remains underrepresented in formal scientific literature.

The American public library, described as a "palace for the people," was established as a free, democratic haven for the public's literary and educational needs, and has since expanded its services beyond book access to include tool rentals, warming centers, postal services, and more. Building on the public library's identity as a democratic commons, this study proposes a physical expansion of the Boston Public Library into Copley Square. Drawing on the library's autonomous architectural language, the proposal extends its social and educational services through the lens of food systems, allowing patrons to take part in the production, processing, and output of urban agriculture.

This conceptual paper proposes a framework for using medicinal and aromatic plants in preschool education, arguing that their volatile compounds add olfactory stimulation to visual and tactile input and may support attention, emotional memory and environmental awareness given the link between the olfactory and limbic systems. It recommends selecting non-toxic, low-allergenic species for school gardens or mini plant areas, growing annual aromatic species from seed so children can observe life cycles, using observation, description and drawing activities, and controlling the duration and intensity of exposure. No empirical data are reported.

A Photovoice study in Addis Ababa, Ethiopia, had women of reproductive age photograph challenges to healthy diets for themselves and their children under five, then discussed the images in five focus groups (n=31 women) split by lower and higher socioeconomic status, analyzed with hybrid deductive-inductive thematic coding. Financial and physical barriers to accessing healthy food, time constraints and perceived poor food safety were major shared contributors to poor diets; lower-SES women also cited limited nutrition knowledge, inadequate family support and poor home food environments, while higher-SES women cited unhealthy food preferences combined with easy access to and aggressive promotion of unhealthy foods. Proposed solutions included government-level measures (job creation, nutrition education, affordable healthy food, household infrastructure investment, expanded childcare, restrictions on unhealthy-food promotion) and societal-level measures (gender equality, community-based loan schemes, and support for urban agriculture).

A book chapter addresses rising food and nutritional insecurity from rapid urbanization in Sub-Saharan Africa, South Asia and elsewhere, noting that 55% of the world population currently lives in cities, projected to reach 70% by 2050. It states that as much as 10-20% of food consumed could be grown within city limits, but that careful planning is needed to reduce risks from soil contamination, plastic pollution, and reuse of grey/black water and city-waste compost. It identifies rooftop gardens, multistory glass buildings, and soil-less methods such as aquaculture, hydroponics and aeroponics as modern forms of urban agriculture, and discusses barriers including land tenure and research priorities for scaling up.

A paper examines Wellington, the capital of Aotearoa New Zealand, and its Town Belt, a green belt paradigmatic of 19th-century planning ideals that has shaped the city's urban form. It argues that this enduring ring of public green space can mask significant gaps in equitable, everyday access to green space within the compact urban area it encircles, with steep terrain and peripheral location limiting everyday use for residents who are less affluent or mobile. It also notes that the city's colonial history has obscured Māori sites of significance, including historic streams — such as Waimapihi — that once flowed from the area now known as the Town Belt but have since been piped and diverted underground. The paper discusses the Town Belt's colonial legacies and Waimapihi to illustrate the limits of protection at the margins and of symbolic recognition within the core, and considers two emerging responses at public housing sites — an Indigenous-led community garden and the planned Frederick Street Park — as responses to the need to retrofit existing spaces in densifying centres and improve accessibility, quality and everyday use. It situates Wellington within debates on shifting from green belts to connected green and blue infrastructure networks, arguing that edge protection must be complemented by sustained, equitable and culturally informed investment integrating natural and built environments to support accessibility, resilience and quality of urban living.

A study examines factors influencing the sustainability of Gallus gallus domesticus (chicken) farming at Jago Karah Farm Community (JKF), one of the urban farming enterprises in Surabaya, Indonesia, which faces complex challenges including limited land and waste management issues, high feed costs and limited production capacity, members leaving the community, underused technology, and institutional aspects needing strengthening. Conducted in February-March 2025 using a saturated sample of all 30 farmer members of JKF, data were collected through field observations and questionnaire-based interviews and analyzed with multiple linear regression in SPSS. Results show that ecological, economic, social, technological and institutional factors simultaneously had a positive and significant effect on farm sustainability, with an explanatory contribution of 99.7%. Partially, the social factor had the greatest influence, followed by technology, institutions, economy and ecology.

A community service program in a residential area of Tasikmalaya, Indonesia, addressed accumulating household organic waste by training residents to convert kitchen waste into liquid organic fertilizer (LOF) at home. Thirty participants, housewives and environmental cadres, took part in situation analysis, socialization on the economic value of waste, technical training in LOF production, and assisted fermentation using an EM4 bioactivator, with knowledge and skills measured before and after. Participants' knowledge rose from 35% to 95%, technical skill from 10% to 85%, and awareness of waste's economic value from 20% to 90%, and participants reported being able to produce LOF independently to support small-scale urban farming on limited land.
