La trama de la naturaleza en el paisaje urbano
2021Soraya Nór · Revista Latino-americana de Ambiente Construído & Sustentabilidade · Global
This article reflects on the urban landscape, focusing on its environmental dimension, to understand how to better integrate natural and social elements in urban spaces. The study proposes the green and blue infrastructure and urban agriculture as planning and territorial management practices, based on a broad notion of landscape, to favor an expansion of nature's presence in city living spaces. These proposals analyze their environmental and socio-cultural aspects.
CommunityBiodiversityPolicyIntraspecific variability of floral and ornamental plants of Onagraceae family and mechanisms of their variety formation
2021E. V. Koroleva, A. F. Petrov, Yu. V. Chudinova · Bulletin of NSAU (Novosibirsk State Agrarian University) · Russia (Novosibirsk)
This review focuses on the intraspecific variability of ornamental plants of the genus Clarkia (Onagraceae) and the clarification of the systematic status of Godetia species introduced into Novosibirsk. Experimental data from genetic and cytological analyses over the last 100 years are presented, showing morphological, karyological characteristics, and genetic variability in various species of the Godetia section. The article concludes that a comprehensive study of environmental conditions' influence on genetic features, ornamental qualities, and flowering biology is necessary for selecting suitable forms and introducing them into urban gardening for Western Siberia's climatic conditions.
DIYBiodiversityUrban–rural linkageA "plan bee" for cities: Pollinator diversity and plant-pollinator interactions in urban green spaces
2020Daniels B., Jedamski J., Ottermanns R., Ross-Nickoll M. · PLOS ONE, 15(7):e0235492 · Europe
A study of pollinator diversity and plant-pollinator interactions in urban green spaces in Germany. Urban community gardens hosted significantly higher pollinator abundance than other park types, comparable to rural reference sites, showing that near-natural design and management, floral diversity, and even small green patches can make cities pollinator habitat.

PolicyBiodiversityUrban areas as hotspots for bees and pollination but not a panacea for all insects
2020Theodorou P., Radzevičiūtė R., Lentendu G., Kahnt B., Husemann M., Bleidorn C., Settele J., Schweiger O., Grosse I., Wubet T., Murray T.E., Paxton R.J. · Nature Communications, 11:576 · Germany
A replicated experiment contrasting Central European cities with neighbouring rural sites, finding cities have lower overall insect richness (e.g. flies, butterflies) but higher bee species richness, flower-visitation rates and pollination than the countryside. It shows urban floral resources support bees while cautioning that not all insects benefit, informing the design of pollinator conservation in urban green spaces and gardens.

2020Carmen M. Ugarte, John R. Taylor · Urban Agriculture & Regional Food Systems · United States (Chicago)
This study evaluated chemical and biological soil-health indicators at 21 urban-to-periurban sites in Chicago (home gardens, community gardens, institutional farms, and private urban farms). It measured soil fertility, nematode trophic composition and food-web indices, and concentrations of lead, arsenic, and zinc; nematode communities differed by management scale and were likely influenced by soil organic matter and pH. Lead, arsenic, and zinc were below levels of concern, and soil fertility was significantly increased by management, particularly in community gardens and urban farms.
CompostBiodiversityCommunityAnalysis of the Soil Microbiome of a Los Angeles Urban Farm
2020Savanah St. Clair, Maryam Saraylou, Daila Melendez, Norman Senn, Serina Reitz, Destini Kananipour, Angelo Alvarez · Applied and Environmental Soil Science · United States (Los Angeles)
This research characterized the arable soils at Los Angeles Pierce College to address health and food-security challenges, using soil physical/chemical measurements, microbial cultivation, and 16S rDNA sequencing on a citizen-science platform. It found plant-growth-promoting, antibiotic-producing and bioremediating bacteria—including abundant Streptomyces, Bacillus and Methylobacteria—across fields with distinct microclimates, and tests indicated that plant-based oils could control antibiotic-resistant bacteria more effectively than common antibiotics. The authors say the results can guide future trials and product development by identifying target soil microorganisms and the most viable fields.

2020Manuela Alves da Cunha, Lidice Almeida Arlego Paraguassú, José Geraldo de Aquino Assis, Arthur Benjamin de Paula Carvalho Silva, Ryzia de Cassia Vieira Cardoso · Journal of Ethnobiology and Ethnomedicine · Brazil (Salvador)
A city-wide mapping of active food gardens in Salvador, Bahia, Brazil, followed by site visits and interviews with gardeners. Only 18 active food gardens could be located in the whole municipality; 17 took part (8 communal, 9 private). Gardeners averaged 55.76 years old and were 52.9% male overall, but women made up 87.5% of communal-garden gardeners and had higher education levels. For 52.9% of respondents the garden was their main source of income; 82.4% ate the produce, 70.6% also sold it and 47.1% donated. Fifty-nine neglected and underutilized species (NUS) were recorded, with 76.5% of respondents reporting they eat 19 of them. The gardens supply affordable food and food diversity without government support — but the very small absolute number of active gardens in a city of this size is equally part of the finding.

2020Maha Deeb, Peter M. Groffman, Manuel Blouin, Sara Perl Egendorf, Alan Vergnes, Viacheslav Vasenev, Donna L. Cao, Daniel C. I. Walsh, Tatiana Morin, Geoffroy Séré · SOIL · Global
This review examines the use of Constructed Technosols (CTs), mixtures of organic and mineral waste, for green infrastructure (GI) in urban spaces. While CTs have high potential to provide multiple soil functions and contribute to urban greening, urban soils are often physically, chemically, or biologically unsuitable for GI features. The analysis suggests that the composition and structure of CTs should be adapted to available wastes and by-products, as well as future land use and environmental conditions, highlighting the need for careful design to overcome existing limitations.

2020Monika Egerer · · Global
This chapter discusses how climate-related factors and climate change may affect the biodiversity of plants and animals in urban agroecosystems, and the ecosystem functions and services they provide. It notes that little research in urban agroecology explicitly investigates the impacts of local weather patterns or regional climate cycles on biodiversity, ecosystem functions, or service delivery. The chapter aims to bridge agricultural and urban literature to enhance understanding of social-ecological processes in urban agroecosystems during the climate change era.

2020Mohammad Hasan Chowdhury, Md. Fahim Sharker Eashat, Chinmoy Sarkar, Nafisa Habib Purba, Mohammad Asadul Habib, Plabon Sarkar, Lincon Chandra Shill · International Multidisciplinary Research Journal · Bangladesh (Dhaka)
Rooftop gardening for vegetable production has gained momentum in Dhaka City, Bangladesh, offering alternative spaces for urban agriculture and contributing to agricultural sustainability. While rooftop agriculture can improve ecosystem services, biodiversity, and food security, its widespread implementation is currently limited by multiple challenges. Green roofs are considered a supplement to other urban food production sources, not a total solution for food security.

2020Tao Li, Jiequn Fan, Qian ZhenGuan, Guohui Yuan, Dandan Meng, Shuiliang Guo, Weiguang Lv · Weed Science · China
A 5-year experiment (2015-2019) in China compared weed occurrence in a corn–earthworm coculture (CE) system and a corn monoculture (CM). The CE system significantly decreased weed diversity, dominance index, total weed density, and biomass, while increasing the weed evenness index. The 5-year mean number of weed species per plot was 8.4 in CE versus 10.7 in CM, and total weed density and biomass in CE decreased by 59.2% and 66.6% respectively compared to CM.
