Against the backdrop of China's evolving urban community governance—from the danwei (work unit) system under the planned economy, through the neighborhood committee system of market reform, to the current community-based governance model—which has eroded kinship-based ties and left communities more fragmented with declining residents' sense of belonging, this research examines how green space development, including community gardens and urban agriculture programs, can build social cohesion and resident wellbeing while facing persistent challenges around sustainable funding models, quantifiable outcomes, and equitable access across socioeconomic groups. The methodology combines CiteSpace visual mapping analysis with inductive and deductive review methods in a three-stage process that analyzes countries with the largest research output and tracks changes in key research topics over time.

Sumit Vij, Vishal Narain · Wiley Interdisciplinary Reviews Water · Global

This review addresses a knowledge gap on how peri-urban residents in Asia and Africa adapt to the impacts of urbanization and climate change on water security. As rural-urban boundaries rapidly blur in the global South, peri-urban spaces are characterized by weakening access to water resources, depleting common property institutions and poor civic engagement, and the review presents the persistent marginalization of peri-urban residents from a water security perspective, while also showing that they do develop adaptation measures. Existing literature is found to focus primarily on (1) increased vulnerability of peri-urban agriculture and allied sectors, (2) barriers and enablers to water-security-related adaptation planning, and (3) justice in peri-urban areas, and the review calls for further study of emerging cooperation and collective action that could reduce conflicts between peri-urban and urban inhabitants and improve water security.

Abdul-Salam Ibrahim, Marney E. Isaac, Thembela Kepe · Land Use Policy · Ghana

Focusing on Ghana, where floods driven by urbanization and climate change are destabilizing urban systems in which land tenure is integral, this study drew on political ecology and land-tenure-security frameworks to examine how floods affect the land tenure security of flood victims. Based on semi-structured interviews with flood victims and planning officials, it found that flood-induced rezoning and new planning schemes, tenant insecurity, relocation, loss of land documents, and threats to urban agriculture all affect flood victims' land tenure security; possessing land documents was found to be important for tenure security but not an absolute condition for victims' perceived security. Post-flood land-use planning for flood risk management was found to have dual potential — it can enhance tenure security and bolster community resilience, but when carried out in an exclusionary way that overlooks the urban poor, it can instead perpetuate inequality and tenure insecurity. The study recommends tenure-responsive land-use planning that embeds contextual, procedural, and distributive equity principles into planning responses to urban floods.

A qualitative, exploratory study of environmental education in Mato Grosso, Brazil combined literature review, document analysis and study of practices in municipal and state schools. Practices such as school gardens, recycling workshops, selective waste collection and digital tools were found effective for instilling socio-environmental values when integrated into the curriculum with community participation. The study also reports that insufficient teacher training, infrastructure limitations and project discontinuity still undermine the effectiveness of these actions.

Mouza Mohammed Eissa, Mohamad Zahir Zainudin, Norun Najjah Ahmat · International Journal of Social Science Research · United Arab Emirates

A qualitative study conducted semi-structured interviews with 35 stakeholders — home farmers, commercial producers, policymakers and agritech developers — in the United Arab Emirates, examined against the National Food Security Strategy 2051. It found 70% of home farmers engage in urban agriculture to reduce import dependency, but are constrained by high water costs (cited by 70%) and limited technical training (55%). Commercial farms widely use hydroponics (88%) and vertical farming (62%), though energy-water trade-offs limit scalability. Stakeholders emphasized AI-driven tools for water-use optimization (75%) and blockchain for traceability (45%); the most desired digital-platform features were real-time soil and weather data (90%), centralized subsidy access (80%) and market linkages (65%), though fragmented data systems currently limit their effectiveness. Policy implementation gaps persist, with 60% of farmers unaware of subsidy programs and minimal integration across agricultural initiatives; the study recommends expanding solar-powered irrigation subsidies, improving training and extension services, and developing a unified digital platform connecting farmers, policymakers and agritech stakeholders.

An article reports on a community activity strengthening local food security through sustainable, integrated urban farming in Rowosari Village, Tembalang District, Indonesia. It combines hydroponic cultivation with catfish aquaculture in limited spaces such as home yards, rooftops and vertical surfaces, and integrates waste management and plant nutrition. The activity involved lectures and discussions plus hands-on training on vertical hydroponic installations and catfish pond cultivation in the village, followed by monitoring and evaluation.

Anthony Steven, Iriani Atrika, Doris Febriyanti, Siti Zubaidah · Government & Resilience · Indonesia (Palembang)

This case study examines collaborative governance between local authorities and community stakeholders in Palembang, Indonesia, a low-lying delta city on the Musi River facing recurrent flooding, food insecurity and disrupted supply chains driven by urban expansion, poor drainage infrastructure and climate-related rainfall variability. It analyzes local policy responses, community-led initiatives such as floating vegetable gardens, and urban farming on flood-resilient land, finding that while municipal disaster agencies provide early warning and evacuation support, food access and distribution during floods are primarily sustained by grassroots networks and community-organized food banks.

This normative-juridical legal study examines the North Labuhanbatu Regency Government's authority over plasma (community garden) development, a legal obligation for plantation companies renewing their Right to Cultivate, in the context of a land dispute with PTPN IV Regional 1 in South Merbau. It finds that the regency government, through its Agriculture Office, has not imposed administrative sanctions on the plantation company that failed to develop plasma gardens for the South Merbau community, and concludes the government appears to have failed to exercise its authority to secure community welfare.

Kelsey Ryan-Simkins · Local Environment · United States (Ohio)

This study used multilevel negative binomial regression to examine the relationship between urban agriculture site locations and sociodemographic and neighbourhood environmental characteristics at the census tract level in Ohio, USA. Findings challenge the idea that urban agriculture is placed in areas with low food access, raising questions about the food-access rhetoric used to promote urban agriculture, a movement critiqued for often being led by upper-class, urban elites, and contribute to debates about the roles of race and gentrification in urban agriculture.

Stefano Follesa, Leila Farahbakhsh, Xinxin Song · DOAJ (DOAJ: Directory of Open Access Journals) · Global

A paper examines urban agriculture as a process capable of promoting environmental sustainability, social inclusion and the circular economy, proposing ways to use and develop it. Through an interdisciplinary approach based on "demand maps," it presents an implementation model aligning users' needs with design solutions. Critical analysis of case studies identifies benefits including reducing urban heat islands, supporting biodiversity, enhancing food security, fostering social cohesion, and aiding the development of vulnerable communities. The guidelines presented aim to encourage the use of demand maps in urban decision-making processes to support participatory, inclusive and sustainable strategies.

Valentine Opanga · Urban Political Ecology · Kenya

A study examines how green urbanism is imagined, politicised and contested in two informal settlements in Nairobi, Kenya, Korogocho and Pumwani-Majengo, using a mixed-methods approach combining Feminist Urban Political Ecology, Postcolonial Urbanism and Travelling Models, drawing on 45 semi-structured interviews, six focus group discussions and a review of policy documents. It shows that international greening agendas are selectively interpreted, reworked or resisted rather than adopted as a unified global sustainability narrative. Findings reveal that state-led greening initiatives, even when aligned with global frameworks, can reinforce spatial inequality, displace low-income residents and obscure colonial-era land injustices. At the same time, grassroots actors engage in context-specific greening practices such as urban farming and dumpsite reclamation driven by survival and care, representing forms of environmental agency that challenge dominant models.

A survey of 330 peri-urban farm households in Hyderabad, India, using multi-stage sampling and a Double Hurdle Model to analyze the decision to diversify farm activities and the intensity of that diversification. Results show the initial decision to diversify is strongly shaped by socio-environmental factors — proximity to urban areas, sole reliance on farming for income, household size and risk attitudes — while diversification intensity is largely determined by farm-specific resource conditions such as soil fertility and farmers' subjective assessment of production and market uncertainty. The study concludes that peri-urban farms in India are moving toward diversification, but at low intensity, particularly among small and semi-medium landholdings.

Beth Haney · The Nurse Practitioner · United States

A policy-advocacy article by a US nurse practitioner (NP) arguing that NPs, positioned at the intersection of healthcare and community well-being, can lead food-system reform to expand access to healthy food and reduce pesticide and herbicide use. Citing CDC data that over 40% of American adults have obesity and that diet-related disease is among the leading causes of preventable death, the article lists policy goals including expanding SNAP and WIC to add incentives for fresh-produce purchases, supporting farming communities producing quality, pathogen-free, organic food, and backing urban agriculture, farmers' markets and farm-to-school programs.

A 2025 study in the Journal of Sustainable Development Law and Policy used Onaiza, a low-rise mixed-use residential neighbourhood on Qatar's western coast representative of suburban Doha, as a case study to examine how urban agriculture could be integrated into land use policy as a climate-change mitigation strategy in Doha Municipality. Drawing on a literature review, examination of successful case studies, and expert interviews, it identified challenges and potential for permitting urban agriculture as a land use, then produced a design proposal amending land use policy through urban planning simulations, subsidies and other incentives. It starts from the premise that food systems, food security and urban agriculture are not yet well positioned within Qatar's existing land use policy, despite the country's vulnerability to food imports and to climate change.

This chapter examines urban gardening in Christchurch, New Zealand, since the 2010 and 2011 Canterbury earthquakes through the lens of resilience — disaster resilience, community resilience, food resilience, and the broader notion of urban resilience. After discussing post-earthquake urban gardening projects in Christchurch, it shows that notions of food resilience are contextually interwoven with the region's earthquake disaster history. It finds, however, that recent initiatives show discussions of food resilience have broadened to become inclusive of a range of environmental, socio-economic, and cultural challenges, with Christchurch's urban gardens becoming part of a wider resilience narrative responding to more diverse crisis scenarios. The chapter argues that this broadening of discussion and focus creates new opportunities — including new funding avenues, research, and strategic investment — for urban gardening.

This scoping review maps the existing literature on food access in American Indian and Alaska Native (AI/AN) communities in the United States onto the Social Ecological Model (SEM). A systematic search of PubMed, CINAHL, SocIndex, Academic Search Premier, ERIC and Google Scholar covered publications from 1988 to 2023, followed by deductive content analysis through the SEM lens using qualitative software; 14 articles met the inclusion criteria. Interventions most frequently targeted the "intrapersonal" and "community" SEM levels, while the "institutional" and "public policy" levels were least targeted, with intervention formats including support for community and school gardens, seed provision, traditional foods at school, family and community events, and meal provision. The review found that valuable research has been conducted on AI/AN food access interventions, many spanning multiple SEM levels, and it points to the importance of leveraging strengths such as culturally aligned programs and traditional foods, calling for further collaboration between AI/AN communities and researchers to develop more informed, multi-level interventions.

Endalkachew Getu, Bereket Ayenew, Kanchan Singh, Mitiku Adisu Worku · Frontiers in Climate · Ethiopia

A random-sample survey of 364 urban farmers in Addis Ababa, Ethiopia, grounded in protection motivation theory (PMT), used structural equation modeling (SEM) to analyze relationships among nine constructs. Selecting new crop varieties, water management practices, adjusting sowing dates and planting drought-resistant crops were identified as the main adaptation practices. Perception of climate change indicators, perceived effects, incentives, subjective norms, adaptation efficacy and self-efficacy positively and significantly influenced farmers' intention to adapt, whereas farmers exposed to maladaptive behaviors showed lower intention to adapt. The survey recommended strengthening local institutions, farmer training, climate information dissemination such as early warning systems, access to extension services, and access to finance.

Robert C. Brears · Cambridge University Press eBooks · Global

This book chapter outlines best practices and strategies for cities transitioning toward becoming circular and liveable. It covers applying circular economy principles across urban sectors including waste management, energy efficiency, transportation and urban agriculture, using a 5R approach — reduce, reuse, recycle, restore and recover. It presents strategies such as energy-efficient financing for building retrofits, grant programmes for water reuse, and e-waste collection and disposal systems, and discusses public participation and stakeholder collaboration through a Quadruple Helix model involving academia, industry, government and civil society. Case studies from Amsterdam, Paris and Copenhagen illustrate circular business models and governance frameworks, and the chapter sets out a roadmap centered on education, policy innovation and community engagement.

Using a triangulation method combining a Delphi survey with a case study, researchers identified life-cycle cost (LCC) components and phases for smart urban farming (SUF) practices in Malaysia. Iterative semi-structured interviews and Delphi rounds built expert consensus on which SUF practices matter for LCC assessment, producing a structured framework for classifying these cost components.

Yu Huan, Steffen Nijhuis, Nico Tillie · Journal of Cleaner Production · Europe

Using Rotterdam as a case study, researchers combined machine-learning suitability modeling (XGBoost with SHAP), deep-learning land-use simulation, and monetary ecosystem-service valuation to compare three scenarios for 2030 and 2050: business-as-usual, suitability-based autonomous transformation, and a suitability-based landscape-approach transformation. Suitability-guided scenarios outperformed business-as-usual, with the landscape-approach scenario producing the most stable multi-decadal outcomes for regulating and cultural services, but provisioning services could plateau or decline when ecological protection constraints limited intensive production.

Grace O’Connor, Kimberley Reis, Georgette Leah Burns, Cheryl Desha, Ingrid Burkett · Journal of Rural Studies · Australia

Researchers investigated the lived experiences of 24 small-scale farmers across 16 ecologically sustainable farms in South-East Queensland and the Northern Rivers region of New South Wales, Australia, examining how their experiences shaped participation in societal transitions to sustainable food systems and contributions to social-ecological resilience. Participants' narratives largely aligned with the "new peasantry" movement, and the paper uses a lens of collective autonomy to discuss how shared responsibility between individuals, communities, organizations, and governments could be reperceived through collective paradigm shifts, community-supported agriculture, and universal basic income.
