Abstract

According to reports, the global sea level is projected to rise by 0.7 m to 1.2 m in the next two centuries, even if efforts are made to reduce greenhouse gas emissions to net zero in the second half of the century. For coastal cities, the implications of sea level rise on coastal zones, particularly those which are densely populated, could be drastic. Sea level rise threatens cities from Shanghai to London and entire countries such as the low-lying Maldives and Kiribati. Furthermore, as climate change could lead to more intense and frequent extreme rainfall events, cities are increasingly vulnerable to flooding. As coastal cities, both Rotterdam and Singapore will need to adopt measures to concurrently address both sea level rise and inland flooding. To achieve this, cities need to take an urban systems approach. Both Singapore and Rotterdam share strong relationships with water–it has been an integral part of planning and building both cities. The Dutch have built Rotterdam in anticipation of too much water, as 26% of the country lies below sea level and 60% is vulnerable to flooding.2 Singapore, on the other hand, has been built in consideration of having too little water. Since its independence, the country has faced challenges in providing an adequate and reliable water supply for its rapidly expanding population due to polluted waterways and insufficient volumes in water catchments. With the advent of climate change, however, Singapore has also been preparing for a future with more frequent and extreme storm events.
