Abstract
In recent years, urban agriculture has been asserting its relevance as part of a vibrant and diverse food system due to its small scale, its focus on nutrition, its contribution to food security, its employment opportunities, and its role in community building and social mobility. Urban agriculture may also be a tool to re-appropriate a range of abandoned or unused irregular spaces within the city, including flowerbeds, roundabouts, terraces, balconies and rooftops. Consistently, all spaces that present a lack of identity may be converted to urban agriculture areas and, more specifically, to urban horticulture as a way to strengthen resilience and sustainability. The goal of this paper is to analyse current practices in the requalification of vacant areas as urban gardens with the aim of building communities and improving landscapes and life quality. To do so, the city of Bologna (Italy) was used as a case study. Four types of vacant areas were identified as places for implementing urban gardens: flowerbeds along streets and squares, balconies and rooftops, abandoned buildings and abandoned neighbourhoods. Six case studies representing this variety of vacant areas were identified and evaluated by collecting primary data (i.e., field work, participant observations and interviews) and performing a SWOT analysis. For most cases, urban horticulture improved the image and quality of the areas as well as bringing numerous social benefits in terms of life quality, food access and social interaction among participants. Strong differences in some aspects were found between top-down and bottom-up initiatives, being the later preferable for the engagement of citizens. Policy-making might focus on participatory and transparent planning, long-term actions, food safety and economic development.

Due to an increased global population, in urban areas which hold 54% of the world’s inhabitants [1], cities are growing and changing rapidly and without concerted planning
We identify the typologies of vacant areas present in the city of Bologna that have a potential to be requalified as horticulture areas
We analyse case studies that exemplify the different uses of vacant areas for urban horticulture
Summary
Due to an increased global population, in urban areas which hold 54% of the world’s inhabitants [1], cities are growing and changing rapidly and without concerted planning. Consequences of this growth can be observed in the so-called urban sprawl, one of the main forms of urban development, characterized by a dispersed, disordered and low-density growth of peri-urban city areas [2]. In New York, local programs are provided with access to land, other resources and technical assistance [11]. Under these circumstances, the public requalification of the urban spaces may constitute the most feasible and rewarding option [16,17]
