This study analyzes criminal liability in cases where electrified cables, installed to protect crops from wild animals in community gardens, resulted in fatalities in the Aceh region of Indonesia. Using a normative legal research approach, the study of death cases in Bireuen and Aceh Timur showed that the installation of electrical cables leading to loss of life was caused by the perpetrator's negligence in adhering to safety standards, fulfilling elements of criminal negligence under Indonesian criminal law. The resolution pattern for these cases follows the litigation route.

The Nairobi River riparian reserve in Kenya has undergone immense land use and land cover changes over the past 20 years due to urban development. A survey of 650 respondents revealed that urban agricultural activities dominated the upper segment at 69%, commercial ventures constituted 79% of the middle segment, and residential usage comprised 89% in the lower segment. These activities caused significant degradation from crop cultivation of river slopes, pollution infiltration, and loss of biodiversity, indicating a severe depletion of the riparian space's functions.

This narration observes a community garden as a space of social diversity, functioning as a "cosmopolitan canopy" where people from different backgrounds interact. While a cosmopolitan spirit exists, the garden is not neutral; its permeable boundaries and internal segregation indicate it is permeated by power dynamics and control.

Sara Mahdizadeh, Yun Gao · Local Environment · United Kingdom

This qualitative study, based on 16 semi-structured interviews, examined motivations and barriers to participation in community gardens in Huddersfield, UK. Key motivations included social interaction, mental well-being, and skill development. Reported barriers were declining volunteer numbers, physical workload, limited institutional support, and accessibility challenges.

Emmanuel Ndhlovu · Discover Sustainability · South Africa

This article critically analyzed food system policies and actions in four South African cities, drawing from grey and academic documents. It found that the government is failing to achieve food security, with approximately 58 million people facing food insecurity in 2023. The study concludes that transforming South African food systems requires coherent policies, shortened supply chains, integration of food into urban planning, and increased support for farmers, among other actions.

Suzana Márcia Souza dos Santos, Clecia Simone Gonçalves Rosa Pacheco · Editora Científica Digital eBooks · Brazil

This study analyzed the experience of the Vila Galvão Women Workers' Benevolent Association in Casa Nova, Bahia, Brazil, which produces organic vegetables in urban and peri-urban contexts. The study aimed to characterize the productive, commercial, and sociocultural aspects related to organic vegetable production and commercialization, identifying main marketing channels and understanding difficulties faced by producers. It concluded that organic production, combined with collective organization and the strengthening of the solidarity economy, represents a viable alternative for a more just, sustainable, and female-led rural development model.

This narrative review explored how urban expansion at the rural-urban fringe drives the loss of productive agricultural land, biodiversity, and ecosystem services. The review examined how these competing interests can be negotiated spatially, emphasizing the role of multifunctional green infrastructure to integrate both food production and ecological function across the urban-rural continuum.

Letícia Englete de Mello, Dirlane de Fátima do Carmo, Daiane Cecchin, Leonardo da Silva Hamacher, Marcel Carvalho Abreu, R. M. Anjos, Mariana Vezzone · Revista de Gestão Social e Ambiental · Brazil (Rio de Janeiro)

This study investigated the profile of 159 urban and peri-urban agricultural producers across 29 municipalities in Rio de Janeiro State, Brazil, using quantitative interviews and statistical analysis. Producers were predominantly men over 50 with limited education, cultivating small plots with organic methods but receiving little technical support. Key challenges identified were a lack of assistance and resources, and urban agriculture's potential is hindered by the absence of effective public policies.

This study examines the urban dimension of agricultural heritage, specifically urban orchards, in cities where agrarian activity is deeply intertwined with their origin and evolution. Using Nerja, Málaga, Spain, as a case study, the research highlights that accelerated urban transformation in recent decades has led to a rupture, undermining agrarian logic by abandoning historical growth practices. The study emphasizes the fundamental role of agrarian activity in built environments and advocates for the protection of urban orchards.

Belma Soto-Fernández, Lurys Bourdett-Stanziola · Asian Journal of Agricultural and Horticultural Research · Latin America

A documentary review on the importance of urban gardening in Latin America revealed that urban gardening, when approached through the lens of agrobiodiversity, has become a key strategy for safe food production and environmental sustainability. However, it was found that several Latin American countries lack clear and established laws to regulate this activity. Preliminary evidence of rotavirus was detected in fresh vegetables from an urban garden in Panama, indicating that urban gardens can become infection foci capable of causing diseases of public health and veterinary importance.

Gideon Baffoe, Philip Antwi‐Agyei · City and Environment Interactions · Ghana (Accra)

This mixed-methods study analyzed the role of urban agriculture (UA) in climate resilience in Accra, Ghana, from the perspective of policymakers. While UA contributes to food security, water use efficiency, and ecological protection, its integration into policy frameworks was found to be limited due to challenges such as weak institutional coordination, competing economic priorities, and governance inefficiencies.

Fuchaka Waswa, Duncan Gichabe, Ruth Kahuthıa-Gathu · Journal of the Kenya National Commission for UNESCO · Kenya (Ruiru)

This study investigated land use changes in Ruiru Sub-County, Kenya, from 1988 to 2024 using GIS. By 2024, agricultural land had decreased by 45.62%, while urban land use increased by 509%, and bare/rocky areas rose by 133% due to abandoned stone mining. The decline in agricultural land leads to reduced industrial crop areas and a shift to leafy vegetables, with an expected increase in agro-chemical use in intensive peri-urban farming.

This study examined agricultural land use change in Lagos Metropolis, Nigeria, between 1984 and 2024 using Landsat satellite images and spectral indices. Findings indicated that farmlands in the study area declined by 13.03% between 1984 and 2013, and by 21.79% between 2013 and 2024. Between 1984 and 2013, 89.48% of farmlands were converted to other land uses, and between 2013 and 2024, 73.51% were converted. Normalized Difference Vegetation Index (NDVI) results also indicated a deterioration in the environmental condition of urban farmlands.

Moses Wanyakha, Nancy Grudens‐Schuck · International Journal of Agriculture Extension and Social Development · United States

This qualitative study reviewed data from 32 counties in Iowa over five years to assess stakeholder participation in Master Gardener community garden donation programs. The analysis found that while these programs engage many stakeholders, the involvement of food pantry patrons in the planning process was low. This low patron involvement limits the programs' ability to effectively serve the community and achieve sustainability and efficacy in providing fresh produce.

Jelena Salmi, Anna Krzywoszynska · Environmental Science & Policy · Finland

A discourse analysis of 103 governance and grey literature documents in Finland examined the politics of soil biodiversity indicators. The study found that eDNA is the preferred scientific basis for soil biodiversity governance in Finland due to alignment between scientific and policy groups. However, land workers' organizations criticize eDNA methods, arguing they risk obscuring local specificity and creating environmental and social injustice, potentially alienating land management groups.

A qualitative descriptive study investigated stakeholder synergy in urban farming programs in Surabaya, Indonesia. Data was collected through interviews, documentation, and observation involving the DKPP, agricultural extension officers, farmer groups, and the local community. Strong commitment, competence, awareness, and continuity were identified as driving factors for successful implementation, but challenges include declining active farmer groups and limited facilities.

Rueda, Ximena · Socio-Environmental Systems Modeling · Africa

A 2025 comparative analysis examines agricultural, economic, and biodiversity policy across Cameroon, Kenya, and Colombia in the context of agricultural expansion, using discourse analysis of policy documents via the Nature Futures Framework and Life Frames Framework, an evaluation of budgets allocated to major agricultural and biodiversity policies, and stakeholder interviews. It finds a shared struggle across all three countries to harmonize agricultural development with biodiversity conservation despite differing institutional capacities, historical pathways, and sociocultural contexts, with agriculture continuing to dominate policy agendas and resource allocation even as recognition of biodiversity's importance grows. Nature is framed primarily in instrumental terms, most strongly so in Colombia's utilitarian "Nature for Society" orientation, with intrinsic and relational values rooted in Indigenous cosmologies weakly reflected in implementation; funding for biodiversity-related ministries remains minimal relative to agriculture in all three countries — Kenya's environmental budget rarely exceeds 0.3% of national expenditure, with Cameroon showing similar disparities and Colombia's allocations continuing to favor agricultural expansion — and institutional fragmentation further undermines this governance.

Mwangi Kamau, Wanjiku Otieno · International Journal of Veterinary Sciences and Animal Husbandry · Kenya

This study characterized the physicochemical quality of untreated wastewater from three small-scale slaughterhouses on the outskirts of Nairobi, Kenya, and measured its effect on soil microbiology at 0, 50, and 200 meters from the discharge point during both wet and dry seasons. Wastewater biochemical oxygen demand (BOD5) ranged from 1,840 to 2,620 mg/L and chemical oxygen demand (COD) from 3,410 to 4,870 mg/L, exceeding Kenyan discharge standards by 6- to 10-fold. Total bacterial counts in soil at the discharge point were 2.7 times higher than at 200 m (p<0.001), and total coliform counts were 4.1 times higher (p<0.001). The Shannon-Wiener diversity index rose significantly with distance from the discharge point (1.42±0.14 at 0 m vs. 2.34±0.18 at 200 m; p<0.001), indicating that wastewater irrigation selects for a less diverse, coliform-dominated soil microbial community. Seasonal variation was significant for BOD5 and coliform loading but not for the diversity index.

Shuang Gan, Wanglin Yan · Applied Geography · Japan

A multi-scale analytical framework examined changing relationships between urban expansion and farmland protection during the transition from population growth to decline, applied to the Odawara region of Japan. Since population decline began in 2010, conflicts between urban expansion and farmland protection have remained concentrated along the urban-agricultural fringe, with farmland loss and fragmentation continuing despite reduced development pressure, and population change was found to indirectly cause paddy field loss via built-up land expansion with a five-year lag. The main driver of farmland loss has shifted from urban development to agriculture-related loss driven by labor shortages and low farming efficiency, and agricultural promotion areas moderately retain paddy fields but offer only limited protection against fragmentation.
