Small‐scale silvopasture: Addressing urban and peri‐urban livestock challenges in the United States with agroforestry practices
2022Ashley Conway, Christine Nieman · Urban Agriculture & Regional Food Systems · United States
This literature review identifies three key barriers to keeping livestock in US urban and peri-urban agriculture—animal feed resources, water quality and nutrient cycling, and use of heavy-metal-contaminated sites—and argues that agroforestry (silvopasture) practices can help address them. The authors propose two theoretical silvopasture systems, one for urban and one for peri-urban settings, and call for future whole-system research.
Organic cycleBiodiversityBiological Control Services from Parasitic Hymenoptera in Urban Agriculture
2022Joshua Earl Arnold · Insects · United States (California)
Over two growing seasons, this study sampled brassica crops at urban agriculture sites spanning a gradient of surrounding landscape imperviousness, size, and management to assess parasitic Hymenoptera abundance, richness, and parasitism of the cabbage aphid. On-farm agroecological practices—mulch coverage, floral richness, and crop-plant richness—and larger on-farm noncrop area increased parasitoid abundance, and greater crop-plant richness raised aphid parasitism, supporting the enemies hypothesis in urban agroecosystems.
BiodiversityWith sustainable use of local inputs, urban agriculture delivers community benefits beyond food
2022María Teresa Gómez-Villarino, Teresa Briz · California Agriculture · United States (Berkeley)
This study examined urban gardens in Berkeley, California, and Madrid, Spain, to observe how agroecological principles—efficient, sustainable use of local resources and inputs—are practiced. It reports that gardens using good ecological practices provide a wide range of ecosystem services, including cultural services such as places to socialize, and can serve as model urban agricultural centers contributing to the UN Sustainable Development Goals.

2022Lawrence D. Harder, Ronald M. Miksha · Oecologia · Germany (Munich)
A re-analysis of the observations behind Renner et al. (2021), which had concluded that an increase in managed honey bee hives between 2019 and 2020 intensified competition with non-Apis bees in the Munich Botanic Garden, Germany. The comment shows that the change in hive numbers did not statistically alter honey bee visitation to 29 plant species either within or between years, so the shift in the proportion of non-Apis bees among visitors is better explained as a response to reduced overall floral resource availability in 2020. The claim that urban beekeeping suppresses native pollinators is therefore supported by some observational studies and contested by re-analyses that find the statistical basis insufficient.

2022Joshua Newell, Alec Foster, Mariel Borgman, Sara Meerow · Cities · United States (Detroit)
A study in Detroit's Lower Eastside (~15 sq. miles) examined the spatial extent, characteristics, and residents' perceptions of urban gardens using spatial analysis and interviews. Gardens covered less than 1% of vacant land and were often ephemeral. Primary obstacles to scaling up urban agriculture in Detroit include uncertainty over land tenure, environmental pollutants, potential ecosystem disservices, and a lack of government support and capital investment.

2022Fa Likitswat, Alisa Sahavacharin · Journal of Architectural/Planning Research and Studies (JARS) · Thailand (Bangkok)
This research analyzed landscape transformations, specifically agricultural landscape structures and functions, in eight selected sites in the urban fringe of Bangkok from 1952 to 2018. The study found that the significant loss of agricultural landscape in Bangkok's peri-urban areas resulted in the loss of seasonal water retention areas, productive landscapes, and urban wildlife habitats. It concludes there is a research gap regarding the lack of policies and practices to promote ecosystem services linked to preserving peri-urban agriculture in Bangkok.

2022Joan Casanelles‐Abella, Simone Fontana, Bertrand Fournier, David Frey, Marco Moretti · Ecological Applications · Switzerland (Zurich)
This study in 23 urban gardens in Zurich, Switzerland, examined feeding niche partitioning between wild bees and honeybees. Researchers found that feeding niche partitioning increased with wild bee species richness and in sites with lower landscape-scale resource availability, which also had lower honeybee abundances. However, beekeeping intensity at local and landscape scales did not directly influence community feeding niche partitioning or wild bee species richness, suggesting direct competition for resources was not a main driver for the wild bee community.

2022Alan Dorin, Tim Taylor, Adrian G. Dyer · PLOS Sustainability and Transformation · Global
This study used an agent-based model to explore the impact of insect flower constancy, heterospecific pollen transfer, and crop patch size on pollination in urban farms. It found that highly constant pollinators were most effective in the smallest patches, while less constant insects performed better in intermediate-sized areas. The model identified an optimal "Goldilocks zone" for pollination around 11m x 11m, suggesting that collaborative management to increase single-crop patch size could improve pollination in community farms.

2022Amelie M. Vanderstock, Cecilia Grandi-Nagashiro, Gaku Kudo, Tanya Latty, Shoko Nakamura, Thomas E. White, Masashi Soga · Journal of Insect Conservation · Japan
An online survey was conducted with 443 adults in Japan to investigate the association between nature and gardening experiences, demographics, species identification knowledge, and biophilia (liking) and biophobia (dislike, fear, and disgust) towards invertebrates. Frequent gardeners were found to be more likely to express biophilia and perceive invertebrates as beneficial, and generally less likely to express biophobia. The results suggest that gardening can serve as a pathway to foster appreciation for invertebrate biodiversity in urban settings.
