Aimed at creating urban green space and food production through urban farming — framed as an innovative strategy for food security amid rapid urbanization — this Indonesian initiative built urban greening through collaboration among community groups, the PKK women's welfare movement, and village (kelurahan) government officials. It was carried out as a five-stage, one-year mentoring program (socialization, trial, implementation, evaluation, and harvest festival) starting in April 2018. The urban farming program, which involved community members, particularly women, was found to improve quality of life by providing access to quality vegetables in the city center and creating a greener environment. The program is described as providing real benefits to the community, the village government, academics, and higher-education institutions, and as needing to be expanded to other regions with active involvement of women to broaden its impact.

This study evaluates willingness to pay (WTP) for urban ecosystem services — particularly cultural and provisioning services delivered by urban agriculture (UA) — in rapidly urbanizing Indonesian cities, using a Contingent Valuation Method (CVM) structured survey and logistic regression to identify socioeconomic predictors of WTP, supplemented by a review of comparative case-study literature to contextualize the findings. The results show strong public support for UA, with higher WTP associated with cultural ecosystem services tied to heritage, aesthetics, and community identity. Key predictors of WTP were income, education, environmental concern, and prior exposure to UA, with regional differences reflecting cultural and policy context. The study notes methodological limitations of CVM in capturing intangible values and advocates mixed-methods approaches incorporating ethnographic and participatory tools.

Set against challenges to social equity, ecological balance, and global food availability from population growth and rapid urbanization, this review paper surveys existing literature linking urban agriculture to multiple Sustainable Development Goals — including poverty eradication, ending hunger, health and well-being, gender equality, economic growth and employment, inclusive urban development, sustainable consumption and production, climate action, land ecosystems, and global partnerships — and discusses policy implications for India. It compiles prior findings associating urban agriculture with locally grown food supply, resource optimization and emissions reduction through urban forestry, rooftop gardens and vertical farming, reduced food miles, and education, skill-building and community participation opportunities including for women and youth. The paper presents no original empirical data of its own.

A study of the "vegetable alley" system—cultivating food crops, ornamentals, and medicinal plants in narrow residential pathways—in Yogyakarta City, Indonesia (2025) surveyed 80 respondents selected by simple random sampling, using descriptive analysis and Spearman rank correlation. Vegetable alley management in Yogyakarta was rated "good" across planning, organizing, mobilizing, and controlling activities. Farming experience, the role of extension workers, the role of group leaders, member participation, and knowledge were significantly correlated with management quality, while education level showed no significant relationship. The study states that vegetable alley implementation contributes to climate change mitigation by increasing green cover, enhancing carbon sequestration, and reducing the carbon footprint from food transportation.

A theoretical essay on hunger in Brazil (2025) applies the Public Policy Cycle Model to the persistent, structural problem of hunger in Brazilian politics, noting that hunger is not unique to Brazil — about two billion people worldwide experience moderate or severe food insecurity — while all Brazilian regions show nutritional deficits tied to inadequate or insufficient food intake. In this context, it frames urban and peri-urban agriculture (AUP) as a social and public-policy tool for promoting food and nutrition security, examining the agenda-setting and formulation stages of AUP policy through discussions from Brazil's National Conferences on Food and Nutrition Security. Noting the 2024 establishment of Brazil's National Urban and Peri-urban Agriculture Policy and its ties to the UN Sustainable Development Goals, the essay concludes that much remains to be done to strengthen AUP as public policy and consolidate its social, economic, and environmental impact, particularly to make it effective for promoting food and nutrition security.

A study in Bahir Dar, Ethiopia examined the integration of urban agriculture (UA) and green infrastructure (GI) through surveys and interviews with 99 stakeholders, supplemented by participatory observation. The main barriers to integration, based on multiple-response data, were a lack of supportive policies and regulatory frameworks (87%), limited awareness (57%), and space constraints (51%). Multicriteria decision analysis ranked integrated practices as the most effective strategy (score 16.81), followed by edible tree planting at garden centers (16.18), small gardens (13.83), and fence-edge greening (11.46). Structural equation modeling identified thermal regulation and access to fresh food as critical factors for planning sustainable urban systems.

This study examines the integration of environmental priorities into participatory budgeting (PB) processes in selected European cities in Poland, Spain, and Portugal, using a qualitative case-study approach supported by literature review and document analysis. Case studies from Warsaw and Gdańsk (Poland), Barcelona and Valencia (Spain), and Lisbon and Porto (Portugal) were analyzed, drawing on academic sources, municipal budget reports, and environmental planning documents to examine how PB in each city has funded projects addressing green infrastructure, waste management, energy efficiency, sustainable transport, and climate adaptation. The study finds that participatory budgeting in these cities has funded projects including community gardens, green roofs, riverbank restoration, and bicycle infrastructure.

Community activities in which citizens create needed activities in their own region span fields such as welfare, care, urban agriculture, autonomy, and environment, alongside activities organized by groups such as women and youth. This study focuses on the culture, arts, and media field within these community activities, investigating and analyzing cases to build "cultural communities" that activate citizens' cultural engagement and enhance sustainability, categorizing the cases and organizing the characteristics of each type, and proposing specific strategies. It categorizes cultural communities into three types — network-centered, subject-centered, and regional-asset-centered — and proposes measures for revitalization and sustainability: activating networks through weak ties, expanding participants and strengthening solidarity through multi-membership, and diversifying the use of and participation in regional cultural and artistic assets.

This study models spatial and temporal crop rotations on Amsterdam's rooftops using planting-structure optimization for crop rotation planning, to assess how much of the city's dietary demand for specific crop groups could be met by productive green roofs. Using average productive green roof crop yields and climatic variability from 2003-2021, it estimates Amsterdam's potential productive green roofs could achieve urban food self-sufficiency of 52% for selected crops (41-54% accounting for climatic and spatial variability), rising to 71% (50-71%) when the planting structure is optimized. Lettuce-broccoli occupies the largest productive green roof area, at roughly 100 hectares, and six vegetable types were found to match well with Amsterdam's dietary requirements.

This paper examines the multiple urban imaginaries produced through five types of urban agriculture (UA) in Bangkok, Thailand, drawing on a co-production-of-urban-imaginaries lens to analyze how the material and immaterial dimensions of UA — through practices, knowledge production, networking and values — contribute to reimagining the future of a livable city. It identifies compatibilities and tensions among UA network imaginaries for a livable city and how these shape urban design and planning, arguing that addressing these tensions to advance equality and justice requires more ambitious, multilayered UA policy achieved through deepened participatory and critical anticipatory governance.

This study qualitatively explored stakeholders' perspectives on urban agriculture (UA) toward sustainable urban development in Malaysia, using semi-structured interviews grounded in stakeholder theory. It drew on 15 stakeholders selected from different authority levels -- the Department of Agriculture Malaysia and PLANMalaysia at the federal level, the Department of Agriculture Perak at the state level, Subang Jaya City Council at the local level, private property managers, and academicians -- who were top management, practitioners, and officers with relevant background in urban agriculture, urban planning, and real estate. The findings produced a framework of action plans centred on social, economic, environmental, policy, and technological-innovation dimensions, intended to guide policymakers and urban planners in developing action plans for advancing UA toward sustainable urban development.

Jan Grossarth · Discover Cities · Global

This paper critically examines the dominance of quantification—certification scores, KPIs, life-cycle assessment—in sustainability practice for cities and buildings (including urban agriculture), arguing that data-driven metrics strip out the emotional and narrative meaning of sustainability. The authors label the shift from a culturally rich orientation to a purely technical, quantitative practice a "tragedy of sustainability," and argue that narrative-focused interviews and real-life storytelling in architecture and urban planning should not just accompany KPIs and ratings but be prioritized over them. The paper is a conceptual argument, not an empirical study with data or case findings.

A study of the rate and direction of spatial expansion of Robe Town, Ethiopia, into surrounding rural kebeles, and its effect on the tenure security of peri-urban landholders. It combined socioeconomic data from 202 sampled household heads with spatial data from Landsat images taken in 1987, 2002, and 2020. The town grew annually by 18.6% (1984–1994), 11.3% (1994–2007), and 9.3% (2007–2020), with its total area rising from 5.1 km² in 1984 to 80.2 km², a 40.9% overall increase. Over the 33-year period, built-up area expanded fastest southward, reaching 9.91 km from the town's mean center, and grew from 4.38 km² in 1987 to 27.9 km² in 2020; about 10.2 km² of farmland was converted to built-up land between 1987 and 2020. In peri-urban areas of Robe town, 48.9% of landowners lost around half of their farmland, leaving peri-urban landowners feeling insecure about their tenure due to fear of eviction and expropriation at minimal compensation.

A mixed-methods, cross-sectional descriptive study of urban agriculture in Gulele sub-city, Addis Ababa, Ethiopia, examining perceptions, opportunities, and challenges. It combined a survey of employees and farmers, in-depth interviews with farmers, key informants, and experts, and a focus group discussion with civil service employees. The study identified scarcity of urban farmland, scarcity of water for irrigating vegetables, and constraints on various agricultural inputs as core problems, alongside market accessibility issues for selling produce and limited transportation availability, even as vegetable consumption and demand among urban dwellers were rising and government policy treated urban agriculture as a current priority. It also found a negative social attitude among urban dwellers toward urban agriculture, who regard it as old-fashioned work and view urban farmers as backward and uneducated. The study concludes that the Addis Ababa City Administration's urban agriculture development sector needs to work with research institutions to address pest and insect problems and to improve vegetable yield per unit of land.

A study of urban agriculture in Kinshasa, Democratic Republic of Congo—a sector described as vital for food security and employment amid rapid urbanization, food insecurity, and unemployment, where farms face significant challenges including land pressure, restricted access to credit, and lack of institutional support. The study aimed to (i) examine the motivations of agri-entrepreneurs, (ii) assess their impact on farm viability, and (iii) identify the economic and non-economic factors influencing business sustainability, using a qualitative and quantitative survey combining 20 semi-structured interviews across three peripheral zones (via snowball sampling) with documentary analysis. Three categories of entrepreneurs were identified: civil servants farming as a supplementary activity, private-sector employees investing in farming, and traders farming to secure their survival. Non-pecuniary motivations such as social engagement and passion strengthened resilience, but land insecurity, a financing deficit, and lack of training were identified as the major obstacles farms face; observed adaptive strategies included diversification and informal partnerships. The study concludes by calling for integrated strategies to secure land tenure, facilitate access to credit, and professionalize the sector while integrating peri-urban agriculture into urban planning processes.

A chapter examining the implementation of nature-based solutions (NBS) in the Zagreb Living Lab, in the post-industrial area of Sesvete, Croatia, as part of the EU proGIreg project. Key initiatives include the "City Gardens" project, offering citizens free plots for sustainable urban gardening, and a therapeutic garden designed for individuals with disabilities, alongside integration of green technologies including a modular urban farm combining aquaponics with green roofs and walls. Despite challenges from the COVID-19 pandemic and earthquakes, the chapter states these initiatives demonstrated the potential of NBS to enhance urban regeneration, social inclusion, and environmental sustainability, emphasizing co-design processes involving local stakeholders and citizens that successfully fostered community engagement and acceptance of NBS. It discusses challenges and opportunities in operationalizing NBS within urban planning and policy and reflects on the potential for scaling these solutions and their role in shaping Sesvete's future development.

A cross-sectional survey using multistage sampling across 15 neighborhoods (mitaa) in eight wards of Dodoma City, Tanzania, examined types, spatial distribution and gender dynamics of urban agriculture among 300 urban farmers in squatter and non-squatter settlements, using structured questionnaires, focus groups, key informant interviews and field observation. Crop-only farming was the most common of the observed typologies (crop-only, mixed, and livestock-only), with homestead farming linked to more informal cultivation on floodplains and government land in violation of land-use policy. Men dominated farming decision-making overall, though a trend toward joint and female-headed farming emerged among female-headed households, and squatter and non-squatter areas differed in tenure security, rule enforcement and infrastructure access.

This study used a System Dynamics model to simulate five 10-year policy scenarios for an informal settlement in a developing country, addressing settlement consolidation and women's access to formal employment: business-as-usual, time-quality, women's formal employment, circularity (including organic waste management with urban gardens and urban agriculture), and a comprehensive scenario combining all interventions. Individual solutions alone did not fully capture potential synergies, whereas the comprehensive scenario reduced by 47.5% the time needed to improve women's formal employability, a result linked to the settlement consolidation process.

Edwin Javier Ortega Zúñiga · Ediciones Comunicación Científica eBooks · Colombia

A study of Palmira, Colombia — a city with a long tradition as the country's agricultural capital — finds that it nonetheless faces significant food insecurity. Prior research reviewed in the study attributes this to an aging rural population and young people's declining interest in farming (which has shrunk the available labor force and limited adoption of new technology), gender inequality that restricts women's access to agricultural resources and decisions, climate change impacts such as droughts and floods on production, and accelerated urbanization that has reduced cropland and fragmented the agricultural landscape. As a potential response, the study describes a pilot project at four sites in the city that installed small-space vegetable production systems, which it reports functioned as a viable source of fresh food in dense urban settings. The authors call for a multidisciplinary approach combining social, economic and environmental factors to address food insecurity in Palmira.
