ElderlyHealthWelfareHow well do we know green gentrification? A systematic review of the methods
2022Jessica Quinton, Lorien Nesbitt, Daniel Sax · Progress in Human Geography · Global
A systematic review of the methods used in green gentrification research — the claim that adding vegetation such as parks, street trees and gardens raises property values and displaces existing residents. It finds that studies are heavily concentrated on U.S. cases, that early qualitative work has been giving way to quantitative analysis, that almost no attention has been paid to which characteristics of greening (scale, type, location) matter, that demand-side mechanisms remain poorly understood, and that displacement itself — the central concern of the literature — has not been well documented.
PolicyCommunityNo statistical evidence that honey bees competitively reduced wild bee abundance in the Munich Botanic Garden—a comment on Renner et al. (2021)
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.
PollinatorsBiodiversityHow Much Food Can We Grow in Urban Areas? Food Production and Crop Yields of Urban Agriculture: A Meta-Analysis
2022Florian Thomas Payen, Daniel L. Evans, Natalia Falagán, Charlotte A. Hardman, Sofia Kourmpetli, Lingxuan Liu, Rachel Marshall, Bethan R. Mead, Jessica A. C. Davies · Earth's Future · Global
A global meta-analysis extracting 2,062 observations from 200 studies reporting urban crop yields, compared across crops, urban spaces (allotments, rooftops, indoor systems) and growing systems. Urban yields were on par with or greater than global average conventional yields, with the largest gap for cucumbers and gherkins (17 kg m⁻² cycle⁻¹ versus 3.8 kg m⁻² cycle⁻¹ conventional). The authors flag significant limits: observations cluster in Europe (n=516), North America (n=398) and East Asia (n=361), with the seven most-studied countries supplying roughly two-thirds of the data and sub-Saharan Africa only 223 observations; many observations come from researcher-run field experiments with controlled inputs, which is likely to inflate yields relative to ordinary citizen plots; and the literature concentrates on leafy greens and tomatoes while fruit is barely studied.
EconomicsPolicyEcosystem services of urban agriculture and prospects for scaling up production: A study of Detroit
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.

2022Rachael Walshe, Lisa Law · Landscape Research · Australia
This study explored how university masterplans in Australian universities express the benefits of campus community gardens as green community spaces and how they might better aid universities in achieving strategic missions, using a multiple case-study methodology. By comparing dominant themes in community garden literature with the visions of campus masterplans, the research aimed to understand how community gardens might be better positioned as tools for place and community building. The results provided a finer-grained understanding of green infrastructure in campus master planning for a post-COVID-19 moment.
CommunityPolicyHealthPlanning for green infrastructure using multiple urban ecosystem service models and multicriteria analysis
2022Karen Lourdes, Perrine Hamel, Chris Gibbins, Ruzana Sanusi, Badrul Azhar, Alex M. Lechner · Landscape and Urban Planning · Malaysia
This study characterized the spatial distribution of multiple urban ecosystem services (UES) in a rapidly urbanizing catchment in Greater Kuala Lumpur, Malaysia, and developed a systematic approach to integrate UES into green infrastructure (GI) planning. Using InVEST models to spatially quantify and map six UES (heat mitigation, runoff retention, sediment retention, scenic quality, urban recreation, and agricultural production), the assessment revealed that densely built areas generally had low UES provision. A multicriteria analysis identified locations for five GI strategies: conservation of headwaters, reforestation for biodiversity, development and conservation of urban parks, and greening of built infrastructure.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.

2022Yujia Zhang, Jordan P. Smith, Daoqin Tong, B. L. Turner · Landscape and Urban Planning · United States (Phoenix)
A model was developed to optimize the co-benefits of food desert and urban heat mitigation through community garden planning, applied to over 5,000 vacant parcels in the Phoenix metro-area, USA. The study found that the optimal number and locations of community gardens needed for different mitigation goals can vary significantly. The existing 76 community gardens were mostly clustered around urban cores, leaving two-thirds of the metro-area underserved, but spatially optimized siting could double the co-benefits gained and cover more high-need neighborhoods.

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.

2022Imen Bendjemila, Salah Chaouche · DOAJ (DOAJ: Directory of Open Access Journals) · Algeria
Urban sprawl in N'Gaous, Algeria, expanded its land area by over ten times (from 33.7 to 379.7 hectares) and its population by over six times (from 4,887 to 33,515 persons) over 60 years. This rapid growth creates significant issues, particularly for peri-urban orchards, which are the primary economic activity. The study used an analytical approach with Geographic Information Systems to assess the agronomic potential of soils and quantify agricultural land consumed by construction, aiming to achieve an optimal agri-urban balance rather than merely avoiding urban expansion.
