Trans-boundary variations of urban drought vulnerability and its impact on water resource management in Singapore and Johor, Malaysia

This is a collaborative research between the Institute of Water Policy and Asst. Prof. Winston Chow from the Department of Geography (NUS). In this study, we (i.) quantified and identified drought episodes using the Palmer Drought Severity Index (PDSI) in the neighbouring regions of Singapore and Johor, Malaysia, and (ii.) qualitatively examined each region's drought impacts and consequent responses through archival research over the past fifty years. The data indicate that both frequencies and intensities of drought episodes in Singapore and Johor have increased over time, suggesting greater exposure to this hazard. However, there are notable variations in drought impacts in Singapore and Johor, and how each region addresses water resource management to drought with varying degrees of success. Despite the geographical proximity, significant variations in regional adaptive capacities suggest that different drought vulnerabilities exist. We discuss the efficacy of drought responses over different time scales, and suggest that a combination of demand- and supply-side policies, especially in the long-term, should be considered to reduce vulnerability to this hazard.
