CITY IN AN EDIBLE GARDEN: FEASIBILITY OF LARGE-SCALE IMPLEMENTATION OF URBAN FARMING ON HDB ROOFTOPS

Abstract

Burgeoning population and rapid urbanization, coupled with the growing uncertainty arising from climate change, have contributed to pressing challenges facing cities today, for example, food security and increasing carbon footprint due to food imports. In seeking an innovative solution to address these issues in Singapore, this study proposes the large-scale implementation of rooftop farming across existing HDB buildings to reduce reliance on imports and improve self-sufficiency. In doing so, this paper will examine the i) technical and ii) social feasibility of rooftop farming. While the former explores the technical and practical considerations for rooftop farming to be successfully effected in residential areas, including understanding and addressing the practical concerns of affected residents, the main focus of the paper seeks to determine the social feasibility or public receptivity towards rooftop farming. This would be measured by HDB residents' support, willingness to participate, and interest in rooftop farming. Findings suggest that respondents were receptive towards the concept of having urban farming implemented on HDB rooftops. 91.1% indicated support for rooftop farming, with a smaller, but still significant 65.1% who were willing to participate if it were implemented. 78.3% were moderately and very interested in rooftop farming, with 42.1% being very interested in the concept. Despite some operational concerns about safety and the likelihood of mosquito breeding and pests, a high 83.4% of respondents thought it feasible. Many remarked that it is especially appropriate for land-scarce Singapore, and is an innovative idea that should be carried out.
