2025Kyla D. Schulte, Caleb J. Wilson, Anna Tawril, Mary A. Jamieson · Ecosphere · United States (Michigan)
A three-year study across 10 strawberry farms along a rural-urban gradient in Michigan, USA, characterized bee abundance, diversity, and community composition. The study found that urbanization, measured as impervious surface cover, had no consistent effect on overall bee abundance and diversity. While urbanization differentially influenced specific taxa (Halictini positively in year one, Ceratinini negatively in year three), the overall impact was limited, with wild bees, especially native species, being important pollinators in urban agriculture.

2024Margaretha Häggström, Mårten Häggström · The Trumpeter · Sweden
This four-year exploratory study in a clearcut in western Sweden investigated the feasibility of cultivating crops in a nutrient-poor, shadowless environment to support biodiversity. The study found that while it was possible to grow potatoes, peas, and some summer flowers without special efforts, it was difficult to grow other vegetables and root vegetables. The project suggests that planting activities in clearcuts may impact people's sense of human-nature identity and respect for the natural environment.

2023Andrés G. Rolhauser, J. Scott MacIvor, Adriano N. Roberto, Selena Ahmed, Marney E. Isaac · Ecological Solutions and Evidence · Global
This paper addresses the limited understanding of conditions under which stress-tolerant "nurse" plants can facilitate stress-intolerant "protégé" species on extensive green roofs for urban agriculture. It proposes a framework and linear model, integrating trait–environment theory and facilitation ecology, to make testable predictions on protégé species performance along stress gradients. The framework aims to help researchers assess the feasibility of nurse–protégé interactions under various environmental conditions.

2023Pavlo Ardanov, Annette Piorr, Alexandra Doernberg, Sonja Brodt, Jennifer B. Lauruol, Iryna Kazakova, Valentyna Movchan, Lucas A. Garibaldi · Agroecology and Sustainable Food Systems · Global
This study assessed information from multiple sources to design diversified cropping systems with vegetables and spice crops for cold temperate climates, integrating trait and observational data from databases, farmer surveys, and literature reviews. While farmers achieved medium to good levels of their main goals, they failed to reach desired multifunctionality with their polycultures. None of the individual data sources provided a comprehensive dataset, but combining them increased crop combination options while also increasing planning and management complexity.

2021Hayley Q McGough · DigitalCommons - CalPoly (California State Polytechnic University) · Global
This paper investigates why plant façades on buildings frequently die, preventing them from fully realizing benefits like urban heat island reduction and improved air quality. Through interviews with landscape architects, it examines factors for maintaining plant façades and assesses if new approaches, such as earlier integration of landscape architects or biocurtains, can address the high mortality rates. The study highlights that these plant façades often fail, leading to waste and unfulfilled potential.

2020Catalina Cruz-Piedrahita, Caroline Howe, Audrey de Nazelle · Global Transitions · Global
This scoping review analyzed 138 papers to develop a conceptual framework on the impacts of urban horticulture (UH) on public health in the Global North. While UH is proposed as a tool for health improvement, the review notes a lack of systematic information on its benefits, barriers, costs, and risks in these regions. The framework visualizes relationships between UH and public health, providing evidence for both positive and negative connections regarding mental health, physical activity, diet, and socialization.

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.

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.

2010Kevin C. Matteson, Gail Langellotto · Insect Conservation and Diversity · United States (New York City)
The ability of adding 70 plants of seven native wildflower species over two years to augment beneficial insect richness, including bees, butterflies, and predatory wasps, was assessed in New York City community gardens. Bayesian analyses failed to find a strong influence of the native plant additions on beneficial insect richness, even after correcting for prior floral abundance. Butterflies and megachilid bees were found to heavily utilize introduced ornamental and crop flowers in these gardens, even when native flowers were present.

2003Charles Rowley · eScholarship (California Digital Library) · United States (California)
This paper compared the successes and failures of two urban creek restoration programs in California: Temescal Creek (initiated nearly 30 years ago) and White Oak Creek (completed about four years ago). Based on the author's success criteria, the more recent White Oak Creek program achieved significant success, while the earlier Temescal Creek restoration did not reach generally acceptable success levels. This difference is attributed to changes in management and scientific practice over 30 years, including substantial changes in the legal basis for restoration, improved monitoring requirements, and the critical role of properly engineered low flow distribution structures.
