This article examined the barriers and opportunities of the Climate Village Programme (ProKlim) in Aceh, Indonesia. Key stakeholder interviews (N=38) and policy content analysis in three villages within Banda Aceh city revealed hypothetical barriers to CCAM, including the absence of a sustained mechanism for effective flood adaptation, insufficient resources for supporting adaptive urban agriculture practices, lack of community participation, and inadequate integration of scientific and local knowledge into early warning systems. Despite ProKlim being an innovative program, challenges remained, as past disaster events were viewed as distant memories, hindering proactive risk reduction efforts by local authorities and residents.

This process evaluation assessed the reach, effectiveness, adoption, implementation, and maintenance of the New Brunswick School Food Pilot Project (NBSFPP) using the RE-AIM framework in eleven schools across New Brunswick, Canada. While school administrators reported positive impacts on program optimization, student leadership skills, food literacy, and eating behaviors, no significant effect was found on teachers’ perceptions of students’ diet or academic outcomes. Program sustainability was largely dependent on receiving funding.

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.

This study analyzed the financial and economic feasibility of urban farming projects and their role in women's empowerment in Cengkareng Barat and Duri Kosambi sub-districts, Jakarta. Using descriptive analysis, cost-benefit analysis, and the Likert scale, the research found that urban agriculture programs are financially and economically viable, showing positive Net Present Value and a Benefit-Cost Ratio greater than one. Socially, these programs contribute to women's empowerment through additional income, skill enhancement, self-confidence building, and community participation.

Proposes a method for assessing urban-agriculture potential at the residential-community scale, combining cluster analysis, 3D model reconstruction, multi-criteria decision-making and GIS. Low-density high-rise communities showed the strongest spatial suitability, while high-density low-rise communities scored highest on sustainable potential; overall ranking was low-density high-rise > high-density low-rise > large-footprint pitched-roof > old communities. Construction year was the key factor, with building density, gross floor area and roof slope shaping potential via sunlight, planting area and accessibility.

Devotha B. Mosha · East African Journal of Agriculture and Biotechnology · Tanzania

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.

A study of Tello Urban Village, Makassar City, Indonesia, conducted from July to September 2024, analysing the influence of social capital and women farmers' institutions on the development of urban farming. Using purposive sampling, the study involved 20 active members of women farmer groups, analysed with descriptive statistics and multiple linear regression. Results showed that social capital - characterised by information sharing, activity coordination, and collective decision-making - and women farmer institutions functioning as units of cooperation, learning, and production both played a significant role in supporting urban farming development. However, both factors were found to have only a moderate, not decisive, influence on urban farming's growth, indicating that additional external support such as government facilitation, resource access, technological innovation, and policy strengthening is still required.

Tao Shi, Ian MacLachlan · Urban Geography · China

A qualitative case study combining observation and interview data on an informal urban garden in Shenzhen, China. In contrast to formal urban horticulture practices in neighboring areas, grower-squatters were found to claim usufructuary rights through informal transactions, sustaining active urban horticulture for the past decade through non-confrontational land claims, social networks governed by tacit understandings, and self-motivated recycling of resources. Notably, these informal arrangements not only endured but consistently outperformed adjacent formal community gardens, which fell into neglect despite official sanction and investment. The authors argue that such informal practices can contribute to the development of sustainable, self-organizing urban gardens in megacities.

A study of the "Ceinture verte" (Green Belt) in Ouagadougou, Burkina Faso, as a nature-based response to climate adaptation. Established in 1976 and relaunched in 2018, the initiative combines forestry development with urban agriculture, aiming to contain urban sprawl, improve the local climate and strengthen the capital's resilience. The study combined a diachronic analysis of Landsat imagery from 1984-2024 with interviews of institutional actors, associative partners and direct beneficiaries. Results show significant contributions — expansion of dense vegetation in some areas, a perceived improvement in air quality, the creation of income-generating market-gardening activities, and the inclusion of vulnerable populations — but also reveal strong constraints: illegal occupations covering a significant share of the land, fragmented governance, limited access to water, security fragility, and still-limited involvement of local residents. The study discusses the feasibility of a trajectory to 2050 between an optimistic scenario conditional on structural reforms and a critical scenario underscoring current limits, and offers lessons transferable to urban adaptation policies in other Sahelian metropolises.

This paper examines Erbil, capital of the Kurdistan Region of Iraq, as a case of medium-sized-city urban transformation, using planning documentation, project descriptions and spatial development interpretation to ask whether green infrastructure elements such as Sami Abdulrahman Park and the Orbital Green Belt Project function only as environmental enhancement or also as instruments of spatial governance within Erbil's updated master-planning framework, which introduces growth boundaries, zoning reforms, density regulation and environmental overlays amid pressure on peri-urban agricultural land from two decades of demographic and spatial expansion.

A study in Medchal-Malkajgiri District, Telangana, India examined ICT utilization among urban farmers, the relationship between farmer profile characteristics and ICT use, farmers' attitudes toward ICT tools, and constraints on their use. It found smartphones, WhatsApp, YouTube and agricultural mobile applications were the commonly used information sources, with education, age, digital literacy, income and training exposure significantly influencing usage, while constraints including lack of technical knowledge, poor internet connectivity and inadequate training limited effective use of ICT tools.

Framed within studies of racial capitalism and neoliberal corporate food regimes, this article examines how residents of Pennsylvania's Monongahela (Mon) Valley experience and articulate food apartheid — a racialized system of food access — and how it intersects with deindustrialization, capital abandonment, and structural racism. Drawing on engagements across three Mon Valley municipalities, the findings reveal complex geographies of food apartheid intersecting with other markers of racial capitalism: inequitable transportation infrastructure, rising cost of living alongside declining quality of life, and ineffective political representation. Residents interpret these inequities as part of a broader racialized economic injustice favoring neighboring, predominantly white municipalities, compounded by distrust of local government perceived as perpetuating exclusionary policies rather than responding to community demands. In this context, participants envision community-driven solutions that extend beyond food system and urban agriculture initiatives.

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.

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.

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 examines the spatial equity and socio-spatial implications of urban agriculture by analysing the distribution of community gardens under Taipei's Garden City Program (TGCP) in relation to neighborhood-level income growth, using unsupervised machine learning (DBSCAN) combined with spatial statistics (Moran's I and LISA). It finds that garden service density is highly concentrated in central districts with significant service gaps in peripheral areas, while at the citywide scale no significant correlation is found between garden density and income growth -- consistent with the "just green enough" view that low-cost, small-scale, decentralized community gardens are less likely to trigger conventional green gentrification -- though several local areas do show potential spatial coupling between garden presence and income change, pointing to a need for policy attention to distributional equity.

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 qualitative literature study examined forms of environmental damage caused by industrial activity in Cikarang, Indonesia—where industrial sector growth has contributed significantly to the economy while also bringing serious environmental degradation—and assessed the role sustainable agriculture can play in environmental recovery. Analysis of national and international scientific literature found that sustainable agriculture, particularly urban agriculture and environmentally friendly farming around industrial areas, has strategic potential as part of green infrastructure, functioning not only as a food source but also contributing to pollutant absorption, rainwater management, temperature control in the area, and improved soil quality and biodiversity.

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 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.

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.
