Walory dekoracyjne i zdrowotność Tithonia rotundifolia (Mill.) S.F. Blake w nasadzeniach miejskich
2018Marek Kopacki, Krystyna Rysiak, Mariusz Szmaraga · Annales Horticulturae · Poland (Lublin)
This 2014 study near Lublin, Poland, evaluated the decorative qualities and health of Tithonia rotundifolia in urban plantings, including a botanical garden and allotment gardens. Observations at the end of the vegetation period revealed disease symptoms, and mycological analysis of dead plant parts identified isolates of fungi from eleven genera. Dominant and dangerous pathogenic genera, Alternaria alternata and Botrytis cinerea, were found to affect T. rotundifolia.
Environmental trade-offsCommunityBiodiversityAgroecología urbana: diseño de granjas urbanas ricas en biodiversidad, productivas y resilientes
2018Miguel A. Altieri, Clara I. Nicholls · Agro Sur · Global
Although urban agriculture (UA) is estimated to provide 15-20% of global food, its significant contribution to city food self-sufficiency is questionable due to low yields in most existing urban farms. Agroecology can enhance UA's productive potential by offering key principles for designing diversified, productive, and resilient urban farms. This paper describes principles and practices for increasing soil quality and enhancing plant health.

2017Jennifer Wilhelm, Richard G. Smith · Renewable Agriculture and Food Systems · Global
This 2017 global review analyzed 320 peer-reviewed papers on urban and peri-urban agriculture (UPA) published between 2000 and 2014, focusing on UPA's impact on ecosystem services (ES) and land sparing potential. The review found that while UPA research is growing, few studies (n=15) place UPA in the context of ES, and no studies explicitly quantify its land sparing potential. Additionally, few studies (n=19) quantify UPA's production potential, indicating a significant data gap.

2017Michael Kennedy · OpenSIUC (Southern Illinois University Carbondale) · Global
Community gardens can serve as important local greenspaces to address environmental degradation and educate individuals about the importance of food and the environment. However, certain barriers need to be overcome and addressed before community gardens are successfully implemented. Participation and interaction within community gardens may provide a pathway to long-term commitment to sustainability, encouraging individuals to adopt more environmentally supportive behaviors and a deeper commitment to environmentalism.

2017Jennifer Wilhelm · University of New Hampshire Scholars Repository (University of New Hampshire at Manchester) · United States (New Hampshire)
This dissertation addresses agricultural extensification from several angles. Chapter 1's literature review showed an increase in research on urban and peri-urban agriculture (UPA) and ecosystem services, but highlighted a need for quantifying ecosystem services and functions to clarify ecological tradeoffs. Subsequent chapters focused on a mixed-methods study in New Hampshire, surveying approximately 600 residents (494 general population, 103 food system stakeholders) on their perception of forestland conversion to agriculture.

2017Monika Egerer, Alessandro Ossola, Brenda B. Lin · BioScience · United States (California central coast)
This study conceptualizes community garden soils within the novel ecosystem framework, arguing that gardeners cultivate novel agroecosystems from their garden beds' soil. On the California central coast, community garden soils may not be influenced by land-use legacies associated with geographic location. Instead, intensive soil reworking by gardeners can wash out legacy signals and decadal chronological trends, leading to soil homogenization that reduces biophysical ties to the underlying earth.

2016J. Scott MacIvor, Laurence Packer · PLoS ONE · Global
This study modeled the occupancy probability of six solitary bee species using nest boxes set along an urbanization gradient over three consecutive years. Native M. pugnata showed decreased occupancy with increasing building footprint, and a similar but not significant pattern was found for native O. pumila. Conversely, introduced M. rotundata and M. centuncularis, along with native M. campanulae, exhibited increased occupancy with rising urbanization.

2016Ana Cristina Torres, Anne Caroline Prévot, Sophie Nadot · Letras Verdes Revista Latinoamericana de Estudios Socioambientales · France (Paris)
A study of 9 Parisian community gardens revealed the limitations of the dominant approach in conservation sciences and urban planning, which seeks to halt environmental deterioration by establishing an ethical basis of attitudes deemed appropriate for conserving a particular nature, by limiting human-nature interaction. Considering citizen subjectivities, the study offers perspectives to nourish conservation sciences and rethink cities.
Governance failureCommunityBiodiversityPolicyEcosystem services and tradeoffs in the home food gardens of African American, Chinese-origin and Mexican-origin households in Chicago, IL
2016John Taylor, Sarah Taylor Lovell, Sam E. Wortman, M.K. Chan · Renewable Agriculture and Food Systems · United States (Chicago)
In Chicago, semi-structured interviews and plant inventories were conducted with 59 African American, Chinese-origin, and Mexican-origin households regarding ecosystem services and tradeoffs in their home food gardens. A total of 387 plant species were identified; gardens of African American households were rich in ornamental species, while those of Chinese-origin households had a depauperate flora. Shade trees and a developed shrub layer were absent from most gardens, suggesting a tradeoff in ecosystem services favoring food production. Only 9.6% of the inventoried species were native to the Chicago area.

2015Kyung-chan Min, Jee-young Kim, yong-hoon Son · Institutional Repositories DataBase (IRDB) · South Korea
A study in Gwanak-gu, Seoul, South Korea, investigated 45 spontaneous agricultural lands, primarily around Mt. Gwanak, which often present risks like disaster, pollution, and landscape degradation. Using GIS, satellite images, field surveys, and interviews, the study classified these lands into six types. Three types were well-managed, while three types were in poor condition, indicating governance challenges. The research discusses the causes of these conditions and explores the potential for these lands to become community open spaces.

2015Guy M. Robinson, Zhiling Liu · AIMS environmental science · Australia
This paper examines the contradictions between greening and "ungreening" in Adelaide, South Australia, focusing on the city's Park Lands and urban sprawl. It argues that urban sprawl, including recent development on prime farmland, has been antithetical to biodiversity maintenance and greening principles, reducing sustainability capacity. The paper identifies problems such as conflict between biodiversity and protecting residents in bushfire risk areas, stemming from a relaxed attitude towards low-density expansion.

2014Amanda E. Nelson, Andrew A. Forbes · PLoS ONE · Global
This study sampled two plant-herbivore-parasitoid systems across 250 sites in a 360 km2 urban/agricultural landscape to investigate the impact of human development on trophic interactions. It found that herbivorous insect densities were decoupled from host tree densities in urban landcover types at several spatial scales. Furthermore, a parasitoid species was absent from all urban/suburban landcover in one system, even where its herbivore host was common, indicating that human land use patterns limit specialist insect distributions due to dispersal constraints.

2013Yves Cabannes, Isabel María Raposo · City · Europe
This paper conducted a comparative analysis of peri-urban agriculture in Lisbon and London to assess its contribution to migrant social inclusion and urban biodiversity. The study found that social inclusion patterns are city-specific; for example, Cape Verdean urban farming communities in Lisbon strengthen community bonds but do not necessarily lead to better integration into wider Portuguese society. Migrant urban farmers contribute to broadening biodiversity, primarily in Lisbon and to a lesser extent in London.
