Karasungur S., Yavaş M. · Land Use Policy · Türkiye (Erzurum)

A paper that frames urban agriculture as a land-use policy instrument for protecting peri-urban agricultural land from urbanisation, analysed on a grid basis for Erzurum, Türkiye. Its angle is to treat urban agriculture not only as growing food in the city but as an institutional means of restraining farmland conversion. Note: this entry is written from the paper's bibliographic record and title; see the article itself for its figures and conclusions.

Kissoly L. · Frontiers in Sustainable Food Systems · タンザニア・ダルエスサラーム

An exploratory qualitative case study and policy analysis of urban agriculture's current landscape and possible futures in rapidly urbanizing Dar es Salaam, drawing on targeted literature and document review, a policy and regulatory scan, and 52 key informant interviews with municipal actors, urban farmers and food-system practitioners conducted between April and September 2025. Urban agriculture is valued for household food supplementation, small-scale income and fresh-food provisioning through short-cycle vegetable production close to consumers, but remains shaped by tolerated informality, insecure land access, fragmented regulation, contamination risks, weak institutional coordination and pressure on peri-urban land. Five evidence-informed trajectories are proposed — managed river-corridor cultivation; sacks, buckets and roofs for dense-ward micro-production; institutional land clusters; peri-urban foodshed belts with circular-resource hubs; and small-scale aquaculture with insect-based feed — presented explicitly not as tested feasibility models but as differentiated options requiring further technical, environmental, spatial and economic assessment. The paper argues the future depends not on a single large-scale model but on risk-sensitive, institutionally grounded forms of support.

A comparative multi-city case study of urban and peri-urban vegetable seedling systems — a neglected component of urban agriculture — in four rapidly growing cities: Addis Ababa, Nairobi, Dhaka and Metro Manila. Data came from 154 stakeholders including urban farmers, nursery operators, seedling suppliers, agro-input dealers and government officers, complemented by secondary literature. Across all four cities urban vegetable production was dominated by small-scale intensive systems growing predominantly leafy vegetables, while seedling systems remained underdeveloped: informal nursery operations, weak quality assurance, open-field propagation, limited technical capacity and fragmented market linkages, driving widespread reliance on direct seeding and low-quality planting material despite strong demand for quality seedlings. Identified opportunities include improved propagation technologies, certification systems, digital marketing, commercialization of indigenous vegetable seedlings and stronger public-private partnerships. As one of the first cross-continental assessments of urban vegetable seedling systems in low- and middle-income countries, it positions seedling systems as a critical but overlooked part of resilient, nutrition-sensitive urban food systems.

This study assessed whether mixed residential-agricultural land use can sustain urban agriculture and if residential landowners in rapidly urbanizing Ghanaian cities are willing to allocate plot space to agriculture. Researchers surveyed 280 landowners across four peri-urban settlements in Kumasi and used geospatial data to estimate available residential space. Nearly four out of five landowners were willing to cede their backyards for micro-farming, with geospatial estimates identifying 75.65 hectares of available residential area across the settlements, equivalent to approximately 0.03 ha per plot (about 23% of an average 0.13 ha plot). These findings suggest the potential of backyard micro-farming as a strategy for sustaining urban agriculture.

This chapter examines agroecology as a sustainable production paradigm for the horticultural sector, facing challenges like climate change and resource depletion. It reviews the conceptual foundations of agroecology, its application to horticulture, and advances in agroecological practices. Case studies, such as peri-urban horticulture in Argentina, illustrate its promise, but note that a full transition remains incomplete.

This study assessed floristic diversity and agricultural practices around five stormwater drains in Douala, Cameroon, identifying 67 species from 24 families. Floristic diversity, measured by the Shannon-Weaver index (H'= 0.99) and low evenness (E = 0.23), indicated an unbalanced plant community dominated by a few cultivated and ruderal species. The analysis also revealed significant homogenization between drains, suggesting common agricultural practices and environmental pressures in these polluted environments.

This 14-day study examined Lepidoptera diversity in semi-urban agricultural landscapes around Lumbini, Nepal, documenting 30 moth species from six families and 39 butterfly species from five families across various habitats. Moth populations were dominated by Erebidae, and butterfly diversity by Nymphalidae, showing resilience in disturbed habitats. Statistical analyses revealed that shrubland and agricultural habitats supported the highest species richness and evenness, while grasslands hosted fewer species.

Shamir Abujder · AGRO - ECOLÓGICA · Bolivia (Sucre)

This study analyzed the market dynamics of fresh organic products in urban districts of Sucre, Bolivia, examining their potential to strengthen food security and foster sustainable enterprises. The research focused on two groups: consumers and producers/marketers, within the context of urban and peri-urban agriculture. Using a qualitative descriptive approach, it aimed to provide knowledge on the economic viability of commercializing fresh organic products and contribute to citizen knowledge on responsible and healthy consumption aligned with agroecology.

A controlled laboratory experiment cultivated BRS Leila lettuce (L. sativa) in samples contaminated with lithium carbonate (Li₂CO₃) at concentrations of 150 and 200 mol/L. The study found that lithium correlates with other alkaline and alkaline earth elements in the leaves and roots of the lettuce. This indicates a contamination pathway where lithium is absorbed by the plant.

Firdavs Berdikulov, Iroda Orifjonova, Bekhzod Eshboev, Jumanazar Xolmurzayev, Bakhtiyor Abdusayitov · Springer Link (Chiba Institute of Technology) · Uzbekistan (Samarkand)

This study examined agricultural growth in Samarkand, Uzbekistan's peri-urban regions from 2000 to 2024, using government data and predictive modeling. It found that urban populations surged while arable land declined, and the vegetable surplus, though currently meeting demand, began shrinking around 2015, suggesting a tipping point toward shortages. The research indicates that without proactive measures like smarter land allocation and advanced irrigation, Samarkand risks a structural food deficit within a decade.

In peri-urban Rabat, Morocco, a study compared the sustainability of 30 farms (15 organic, 15 conventional) using the IDEA method, assessing agro-environmental, socio-territorial, and economic dimensions with 18 indicators. Organic farms excelled in agro-environmental sustainability and demonstrated long-term economic resilience. Conversely, conventional farms, while more productive, faced socio-territorial limitations and economic dependence on external inputs.

Sadiq Ur Rehman, Muhammad Adeel Mannan, Muhammad Ahsan Shaikh, Muhammad Uzair · Memoria Investigaciones en Ingeniería · Pakistan

In Pakistan, an IoT-based solar-powered smart vertical farming system was proposed to address agricultural challenges like water scarcity. A six-week trial cultivating cherry tomatoes showed the system achieved a 60-65% yield increase, 40% energy saving, and 28.57% water consumption reduction compared to traditional methods. However, limitations included the small trial size and lack of long-term environmental impact data, and scalability challenges such as cost, maintenance, and local restrictions need to be addressed for wider adoption.

SORO Sibirina, TRAORE Aboulaye, KOFFI N’guessan Mathurin, TRAORE-OUATTARA Karidia · World Journal of Advanced Research and Reviews · Côte d'Ivoire (Daloa)

In Daloa, Côte d'Ivoire, tomato and eggplant production is limited by biotic diseases. This study evaluated the antifungal activity of six plant extracts against soil-borne fungal pathogens affecting tomato and eggplant. Eggplant plants treated with Securidaca sp exhibited the greatest tolerance to disease, with a severity index of 2.1%. Aqueous extracts of Securidaca sp and Solanum sp reduced mortality rates more effectively than synthetic fungicide, suggesting they can be recommended as an alternative for controlling soil-borne fungal diseases in tomato and eggplant.

Manamaya Mishra, Dipendra Bikram Sijapati, Bijaya Mani Devkota, Shakuntala Triphathi · Journal of Ecohumanism · Nepal (Kirtipur, Kathmandu)

This paper investigated urban agriculture in terms of urban food security and employment in Kirtipur, Kathmandu, from February to April 2023, surveying 64 households with over 4 Ropany (0.2 ha) of farmland across three urban pockets. The study found that lack of irrigation facilities was the most crucial problem for agricultural development. Other major issues included a lack of modern inputs and technologies, decreased youth interest in agriculture, inadequate road networks, and financial problems.

This study assessed the impact of peri-urban agriculture on food self-sufficiency in Faisalabad, Pakistan, by collecting data from 100 peri-urban farming households and analyzing land use changes from 2018 to 2023 using GIS. Households allocated an average of 12.9 Kanals for seasonal vegetables, consuming nearly half domestically and selling the rest locally. A significant association was found between positive nutritional perceptions and regular access to fresh produce. However, limited government support, weak stakeholder coordination, and inadequate market access were identified as key barriers limiting its broader impact.

Tinawaen Tambol, Emmanuel Kanchebe Derbile, Moussa Soulé · Scientific Reports · Niger

This study investigated peri-urban farming systems in West African Sahel cities. A mixed-method research design, including field and household surveys of 142 peri-urban smallholder farmers, was employed. Results showed that biopesticides/crop and pest management were the most used Climate-Smart Agriculture Technologies (CSAT) in dry-season farming (p = .002). Other technologies included fertilizer micro-dose, organic manure and compost application, flood-tolerant improved varieties, and green energy-based irrigation.

Inger‐Lise Saglie · · Norway

This chapter presents the development of public policies and the main actors in urban agriculture in three Norwegian cities: Oslo, Bergen, and Trondheim. While showing common traits in institutionalization, differences exist in the role of voluntary groups, bottom-up versus top-down processes, networking, relationship to peri-urban agriculture, and implementation in plans. Oslo's approach is politically driven with traditional participatory methods, developing urban agriculture as a social activity and professional food production. In Bergen, the voluntary sector actively co-creates policy and runs a competence center. Trondheim's policy is co-produced annually with growers based on their experiences, with a strong connection to professional agriculture, and has consciously chosen not to develop specific strategies for urban agriculture.

This study ranked urban and peri-urban farmland areas in Norway based on their suitability for urban agriculture (UA) and identified opportunities for extending UA to currently unused farmland. Through collaboration with urban farmers, four key themes and eleven criteria were identified and weighted for on-farm and off-farm sales scenarios. A GIS-based multi-criteria decision analysis (MCDA) using TOPSIS was performed on 1x1 km grid cells. In the City of Bergen, 15.3% (on-farm) and 14% (off-farm) of the total farmland was both unused and highly suitable for UA, compared to 2.8% (on-farm) and 2.4% (off-farm) in Oslo.

This study investigated the motivations and consequences of soil extraction for brick-making in Antananarivo, Madagascar, through 263 interviews with farmers and brick-makers. Findings indicate soil extraction serves as a climate change adaptation strategy, leading to a decline in flood regulation capacity but also a shift to more resilient cultivation practices like raised gardens. Climate change, with shorter rainy seasons, intensifies soil extraction.

This study assesses future climate risks and sectoral vulnerabilities in Ghana's Cape Coast Metropolis using meteorological data and downscaled climate projections through 2100. Findings indicate significant warming trends and heightened rainfall variability, which render peri-urban agriculture highly susceptible to crop failure, fishery declines, and water scarcity. Informal economic sectors are also at risk from infrastructure damage and income impacts.

This article develops a theoretical framework to analyze how digital land registries in Rwanda, specifically in Kigali's peri-urban areas, mediate women's access to formal agricultural credit. The framework posits that despite formal legal equality, digitization can paradoxically solidify existing patriarchal biases within credit assessment algorithms. It reveals that digital land governance is not a neutral solution for gendered credit gaps and can entrench barriers to women's financial inclusion in peri-urban agriculture by systematically undervaluing women's communal land use practices as collateral.

A cross-sectional study in urban and periurban areas of Ndola district, Zambia, assessed malaria vector behavior and insecticide resistance. Urban agriculture practices created highly productive mosquito breeding sites like irrigation trenches and garden ponds, where Anopheles funestus s.s and Anopheles gambiae s.s coexisted. Anopheles gambiae s.s showed high resistance to pyrethroids, carbamates, and organochlorines, indicating that urban agricultural practices increase the risk of sustaining malaria transmission year-round.

This book examines community farms in Latin America, Australia, and China, highlighting tensions between local identities and global transformation. It finds that while industrial expansion in export agribusiness generates macroeconomic benefits, it incurs micro-level costs such as the replacement of peri-urban farms by plantations, loss of biodiversity, and groundwater contamination from pesticides and fertilizers. The study suggests that food system intermediaries are crucial in connecting rural migrants with urban farms and resources.
