T he world has been changing massively over the past few years with severe and possibly permanent alterations to our planet’s geological, biological and ecological systems (Council, 2011). Rapid urbanisation coupled with climate change caused by anthropogenic activities are expected to increase vulnerability to disasters causing uncertainty. The features of climate change in the scale, frequency, severity and unpredictability of extreme weather will continue to grow in the coming years, and at an accelerating pace. Human activities including immense population growth, sprawling development and megacities is another factor that cause threats to the environment thus leading to disasters. As shown in the EM-DAT International Disaster Database (Figure 1), the natural disaster trend worldwide increased three times between 2000 and 2009 compared with the number of disasters between 1980 and 1989 (accuweather.com). The Asia-Pacific region as shown in Figure 2 has been labelled as the world’s most disasterprone region, registering the largest number of people affected, as well as the largest number of people killed, by disasters between 2002 and 2011 (Un, 2013). Fortunately Malaysia, has not been directly affected by serious disasters such as earthquakes, hurricanes, typhoons, tornadoes, tsunamis and volcanic eruption because it is located outside the “Pacific Ring of Fire”. However, it still has to face the wrath of nature in the form of severe flooding. Floods are regular natural disasters in Malaysia that occur annually during the monsoon season. Since 1920, Malaysia has experienced no less than 15 major flood events. In December 2014, Malaysia was devastated by unprecedented flood events that affected large areas of the east coast. The flood was recorded as the worst flood in 30 years, which led to economic losses, failed crops and death. The Worst Malaysian Seasonal Rain in 50 Years Heavy seasonal rain and strong wi
