With increasing urbanization and environmental degradation, urban landscapes are increasingly expected to provide a wide range of ecosystem services typically associated with rural areas, including biodiversity conservation and food production. Because residential landscapes constitute the largest single urban land use, domestic gardens have emerged as a topic of research interest and planning concern. The ecosystem services (or disservices) these landscapes provide, however, have not been rigorously measured, nor have tradeoffs between the services they provide been assessed. In this study, semi-structured interviews were conducted with 59 African American, Chinese-origin or Mexican-origin households with on-lot or vacant lot food gardens in Chicago. Crop plants and cultivated ornamental plants on the lot were inventoried and mapped at the species level. A total of 123 edible plant taxa from 25 families and 288 ornamental plant species from 85 families were identified, for a combined total of 387 species from 90 families. Cumulatively, the gardens of African American households were relatively rich in ornamental plant species and families, while those of Chinese-origin households had a depauperate flora. Crop plant richness was more even across sample types. Shade trees and a developed shrub layer were absent from most gardens, possibly representing a tradeoff in ecosystem services in favor of food production. The richness of the aggregate 2.1 ha of residential property inventoried in this study was comparable with or exceeded that of a 34 ha prairie remnant west of Chicago. However, only 35 (9.6%) of the inventoried species were native to the Chicago area.

In the United States, interest in urban farms and community gardens is flourishing, yet the urban home food garden (UHFG) and its contributions to urban systems have been overlooked and understudied. To begin to address this gap, we are conducting a mixed methods study of African American, Chinese-origin and Mexican-origin households with home gardens in Chicago, IL. Study methods include in-depth interviews, participant observation, ethnobotanical surveys and analysis of the chemical and physical properties of garden soils. As of this writing, findings indicate that home gardening has an array of beneficial effects, contributing to household food budgets and community food systems, the reproduction of cultural identity and urban biodiversity. The majority of informants in the study were internal or international migrants. For these individuals, gardening, culture-specific food plant assemblages and the foodways they support represent a continuation of cultural practices and traditional agroecological knowledge associated with their place of origin. The gardens of some migrant households also harbor urban agrobiodiversity with roots in the Global South. At the same time, gardens may have less salubrious effects on urban systems and populations. A lack of knowledge of safe gardening practices may expose vulnerable populations to environmental hazards such as soil contaminants. Gardeners in this study reported using synthetic chemical fertilizers and pesticides, sometimes indiscriminately, and the repeated application of synthetic fertilizers and compostmay contribute to the nutrient loading of urban stormwater runoff. These effects may be moderated by the relatively low bulk density and high porosity of garden soils due to tillage and the application of organic matter, which can be expected to enhance stormwater infiltration. While the UHFG’s potential contributions to urban systems are significant, outreach and research are needed to help gardeners grow food safely and sustainably in ways that contribute to overall ecosystem health.

In the United States, interest in urban agriculture has grown dramatically. While community gardens have sprouted across the landscape, home food gardens—arguably an ever-present, more durable form of urban agriculture—have been overlooked, understudied, and unsupported by government agencies, non-governmental organizations, and academics. In part a response to the invisibility of home gardens, this paper is a manifesto for their study in the Global North. It seeks to develop a multiscalar and multidisciplinary research framework that acknowledges the garden’s social and ecological or material dimensions. Given the lack of existing research, we draw on the more extensive literature on home gardens in the South and community gardens in the North to develop a set of hypotheses about the social-ecological effects of urban home food gardens in the North. These gardens, we hypothesize, contribute to food security, community development, cultural reproduction, and resilience at multiple scales; conserve agrobiodiversity; and support urban biodiversity. They may also have negative ecological effects, such as stormwater nutrient loading. Because of the entanglement of the social and the ecological or material in the garden, we review three theoretical perspectives— social ecological systems theory, actor-network theory, and assemblage theory—that have been or could be applied to the multi-scalar and multidisciplinary study of the garden. We also review sampling and analytic methods for conducting home garden research. The paper concludes with a discussion of opportunities to extend the research agenda beyond descriptive analysis, the primary focus of garden research to date.

Always a part of city life, urban agriculture has recently attracted increased attention from diverse groups in the United States, which promote it as a strategy for stimulating economic development, increasing food security and access, and combatting obesity and diabetes, among other goals. Developing effective policies and programs at the city or neighborhood level demands as a first step the accurate mapping of existing urban agriculture sites. Mapping efforts in major U.S. cities have been limited in their focus and methodology. Focusing on public sites of food production, such as community gardens, they have overlooked the actual and potential contribution of private spaces, including home food gardens, to local food systems. This paper describes a case study of urban agriculture in Chicago which used the manual analysis of high-resolution aerial images in Google Earth in conjunction with ArcGIS to identify and map public and private spaces of food production. The resulting spatial dataset demonstrates that urban agriculture is an extensive land use type with wide variations in the distribution of sites across the city. Only 13% of sites reported to be community gardening projects by nongovernment organizations and government agencies were determined, through image analysis, to be sites of food production. The production area of home gardens identified by the study is almost threefold that of community gardens. Study results suggest opportunities may exist for scaling up existing production networks—including home food gardens—and enhancing community food sovereignty by leveraging local knowledges of urban
