Acta Horticulturae 1356. Proceedings of the International Symposium on Urban Horticulture for Sustainable Food Security (UrbanFood2022)
In recent years, urban horticulture (UH) has been increasingly deemed as a sustainable practice that addresses various urban challenges. Research and implementation of UH around the globe have demonstrated that it can fulfill multiple functions and produce a range of market- and non-market-goods and services that may have positive impacts on the urban setting in all three sustainability dimensions (social, economic and environmental). One major social advantage lies in improving food security for either individuals or entire communities. Food security (as defined by the FAO) is based on four pillars: availability (quantity and quality), accessibility, utilization, and stability. Building resilience for food security is particularly relevant in times of crisis (such as in the face of the Covid-19 pandemic). The real impact of UH in supporting sustainable food security will depend on the scale on which it can be applied in cities of the future. In this symposium, our aim was to bring urban food production and food provision into the focus of investigation. Contributions deal with different types of UH (community-oriented projects, commercial farms, gardening, etc.) in intra-urban contexts but also within the broader city-region food system (e.g., peri-urban horticulture). The papers compiled in this book, address the multidimensional benefits and risks of UH on different sustainability dimensions (environmental, economic, social) as well as related challenges and innovations at the production, market, education and policy level. The two final sessions of this symposium were shared with the II International Symposium on Greener Cities: Improving Ecosystem Services in a Climate-Changing World (GreenCities2022) and focus more specifically on the role that UH and green urban infrastructures can play on human health and well-being.
