Umar, Tariq (2020) Making future floating cities sustainable : a way forward. Proceedings of the Institution of Civil Engineers - Urban Design and Planning, 173(6), pp. 214-237. ISSN (print) 1755-0793


It is expected that by 2030, five billion of the earth's population will live in cities. This growth in urbanization results in significant challenges pertaining to environmental and social sustainability. Most of the cities are located near coastal areas and thus under the threat of sea rise. This article explores the floating sustainable cities with the key sustainable factors as an alternative to meet the future urbanization requirement. The purpose of this paper was to find the key sustainability factors and then explore the solutions to achieve them in the floating sustainable cities. A mixed research strategy using qualitative and quantitative approaches was adopted to achieve the aims of this research. The key sustainability factors were derived from the existing literature through a systematic review approach and then ranked using a questionnaire administrated among selected respondents. The top-ranked factors that include energy, water, food, waste, mobility, and habitat regeneration were considered and were further explored using a systematic review method. The review suggests that there are different arrangements and techniques available to meet the future sustainable floating cities requirement. The discussion reveals that the concept of floating cities is at its initial stage and has the potential for multidisciplinary research.
