Margarethe Karpe, Jeremías Lachman, Lili Wang, L.F.M. Marcelis, E. Heuvelink · Sustainable Production and Consumption · Global

A Delphi survey with 108 experts explored urban agriculture's potential contributions to Sustainable Development Goals (SDGs) under a scenario of 30% urban food self-sufficiency. Experts identified SDG 7.2 (renewable energies) as a key challenge due to high energy use, and agreed that none of the evaluated SDG targets for urban agriculture will be met by 2030. They also noted a lack of regulations and public policies for innovative agricultural systems.

This research, conducted in San Juan, Puerto Rico in July 2019, investigates how women experienced the impacts of Hurricane Maria on their urban farms (huertos urbanos). Findings show that while many women enjoy urban farming and it provides fresh produce, almost all women farmers experienced a decline in volunteer participation a few years after the farms' establishment and even more so after Hurricane Maria. Despite this, many women described the urban farms as very important for community food cultivation and gathering.

Katherine Klink · Urban Climate · United States

This study examined whether an urban farm in St. Paul, Minnesota, USA, could mitigate urban heat, using six years of hourly temperature measurements. Mean monthly temperatures at the farm did not differ significantly from nearby tree-covered green spaces. However, mean monthly minimum temperatures at the farm in July and August were approximately 1 °C cooler than the broader urbanized area, with no significant differences in maximum temperatures. These findings suggest the urban farm can potentially reduce the nocturnal urban heat island effect without worsening the daytime effect.

This descriptive qualitative study analyzed external factors affecting the Rumah Anggur Ardo nursery business in Medan, Indonesia, using PESTEL and Porter's Five Forces frameworks. Findings indicate a relatively favorable competitive environment, with urban farming as a hobby presenting a main opportunity. However, significant challenges include high rainfall damaging seedlings and the absence of material support from the government.

Yanxin Liu, Victoria Chanse, Fabricio Chicca · Land · New Zealand (Wellington)

This study evaluated the role of urban agriculture (UA) in enhancing post-disaster food security in Wellington, New Zealand, a region highly prone to earthquakes. It calculated vegetable self-sufficiency by mapping potential productive land, estimating vegetable yields, and assessing post-disaster food demands across multiple scenarios. Potential productive land accounted for 0.3% to 1.5% of the total area, primarily distributed in the eastern part of the city. Results indicate that Wellington's vegetable self-sufficient rates through UA range from 3% to 75%, with higher rates for displaced and vulnerable populations. Realizing this potential will require stronger policy support and integration with urban planning and disaster preparedness.

Babatunde S. Adedotun, Martin Binde Gasu, Ismail A. Oyerinde, Dele Sunday Ogundahunsi, Oluwatoyin David ADEDOTUN · The Journal of Agriculture and Development · Global

This research conducted an extensive literature review on the correlation between urban agriculture and the quality of life of urban residents, synthesizing 20 peer-reviewed scholarly papers published between 2010 and 2022 from databases like Scopus. Urban agriculture was shown to offer economic benefits, community engagement, health improvements, environmental benefits, and cultural connections, but also presented negative externalities such as resource exploitation, contamination, and ecosystem disruption.

Ulrike Pröbstl‐Haider, Magdalena Feilhammer, Alice Wanner · Cities · Austria

This paper analyzed opportunities and barriers for implementing nature-based solutions (NBS) in Austrian cities. A survey of 1055 urban residents investigated conditions under which NBS reduce particulate matter, NO2, and air temperature. Results highlighted the relevance of design types like green corridors and community gardens, and the importance of direct and time payments, indicating that a €45 payment with a 10-minute walking distance to home was acceptable if high environmental benefits were achieved.

Peng Gao, Shuochen Xiao, Fara Diva Mustapa · Climate Risk Management · Global

This comprehensive review synthesized research on urban and peri-urban agriculture (UPA) globally, specifically within the context of its advantages, challenges, and climate change mitigation and adaptation efforts, including technological innovations and policy frameworks. The review demonstrated UPA’s ability to advance social interactions, improve urban microclimates, mitigate the urban heat island phenomenon, and provide essential ecosystem services. However, UPA is limited by scarce land resources and soil contamination, along with water management challenges and regulatory frameworks.

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.

Upinder Kaur, M. Kaur, Aparna Kumari, Deepika Shukla, Rajan Datt, Mehar Chand · Frontiers in Sustainable Cities · Global

This paper proposes a deep learning model, UrbanAgri, integrating ResNet101 and the Sparrow Search Optimization (SSO) algorithm, to identify plant stress in urban agriculture environments. Trained on a heterogeneous dataset of urban crop images, the model achieved an F1-score of 98.9 and ROC-AUC of 0.989, outperforming traditional approaches. This framework aims to reduce crop waste and promote sustainable urban agriculture by accurately detecting biotic and abiotic stress factors.

Henry Mensah · City and Environment Interactions · Ghana (Kumasi)

This study investigated adaptation practices and challenges among 85 urban farmers across three locations in Kumasi, Ghana. Farmers employed strategies like planting local crop varieties, expanding farms, and relocating. However, these strategies are hindered by institutional and technological limitations, financial constraints, lack of climate information, and delays in extension support, indicating significant governance challenges.

This study assessed the sustainability of environmental management practices among peri-urban rice farmers in Ilorin, Nigeria, using a sustainability index. It found that many practices were less sustainable, with 69.51% of farmers relying on chemical sprays and 69.85% using chemical fertilizers. The overall Environmental Management Practices Sustainability Index (EMPSI) for all farmers was 0.492, placing them in the moderately sustainable category.

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.
