This literature review examines the role of urban agriculture as an ecosystem services provider in mitigating urban environmental deterioration. It states that urban agriculture adds various functions across different landscape scales and can provide numerous benefits when managed correctly. The review method compiled literature on urban agriculture and ecosystem services across provisioning, regulating, and cultural service categories. Results describe urban agriculture as taking diverse forms, from private gardens to community plots, addressing limited public funding and promoting greening initiatives; it is described as contributing to biodiversity conservation and to regulating the urban microclimate, including reduced urban heat island effects, wind protection, and pollutant absorption. It is also described as adding aesthetic value to urban spaces, promoting cultural integration, and functioning as a multifaceted strategy for sustainable urban development addressing food security, resilience, and well-being. Amid challenges including threats to urban biodiversity and the need for proper green-space management, the review frames urban agriculture as a holistic approach contributing to cities' visual, cultural, and environmental fabric.

A review synthesizing existing research on how far green roofs can support urban biodiversity, framed by their design and modes of use. It finds green roofs can provide habitat for soil organisms and pollinators as well as plants, but that the effect depends strongly on design such as substrate depth and vegetation diversity, and recommends integrating soil communities into construction guidelines and increasing heterogeneity at roof and landscape scales.

A systematic review of 162 peer-reviewed papers (1978–2022) organizing the role of allotments and community gardens into six themes (community, health, economics, pollution, urban planning, sustainable environment). Ecologically, it concludes that gardens create habitat mosaics that act as refugia for urban biodiversity and that urban agriculture enriches plant diversity, helping conserve native and agricultural biodiversity — and calls for planning and policy frameworks that treat gardens as part of urban green infrastructure alongside greenspace restoration and heat-island mitigation.

This 2023 global systematic literature review examined peri-urban agriculture (PUA) as an ecosystem service, focusing on urbanization pressures and governance. The review found that PUA is crucial for urban areas in terms of food supply, ecology, biodiversity preservation, disaster mitigation, and recreation. However, massive urban expansion is a primary cause of PUA loss, and sociocultural biases have led to institutional constraints on peri-urban management within existing political and regulatory frameworks.

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.

This article aimed to map authors discussing environmental aesthetics in urban agriculture research, inspired by Porteous's work. Using a bibliographic survey and visual representations, the study found no publications intersecting urban agriculture and environmental aesthetics. Research on urban agriculture and landscape was notably greater than on urban agriculture and aesthetics, and studies applying aesthetic theory to urban agriculture were very limited, especially in high-tech contexts like vertical farms.

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.

This study assessed bee visits to experimental blueberry and cherry orchards in an urban landscape to understand how air temperature affects the pollination contribution of honey bees and wild bees. Bumble bees and honey bees were the most important floral visitors, followed by Anthophora plumipes. Honey bees' potential contribution to pollination services decreased with air temperature changes, but this was offset by the niche complementarity of bumble bees.

This study investigated the effect of growing space on maize productivity using the three sisters cultivation system (corn, beans, pumpkins) in grow bags. A completely randomized design with three treatments (75 L, 100 L, and 200 L grow bags) and six replications was used. The highest corn productivity was observed in the 200 L grow bag (318.40 g/cob), but it was not significantly different from the 100 L grow bag (316.20 g/cob). The study concluded that the 100 L grow bag was the optimal growing space for containerized corn using this technique.

This overview identified eight ecosystem services generally attributed to urban agriculture, including food production, microclimate regulation, stormwater retention, and social-cultural values. However, the study found that quantitative evidence for many of these ecosystem services, especially intangible ones, is scarce. It suggests that while urban agriculture could be integral to green infrastructure, further consideration is needed for types, technology, management, and potential tradeoffs.
