Research has clearly shown (and continues to do so) that as a result of changing global climatic patterns countries are becoming increasingly vulnerable to devastating damage to the infrastructure – for example through floods associated with hurricanes of increasing frequency and rise in sea water and ground water level. The Inter governmental Panel on Climate Change (IPCC) has stated that the frequencies of heavy precipitation, as well as rainfall from tropical cyclones, are likely to continue to increase in this century (Pachauri, 2012). As projected by the IPCC, rising sea levels is virtually certain (>99% probability of occurrence) to continue, and increases in intense precipitate events are highly likely (>90% probability of occurrence) to become more frequent in widespread areas of the world, and as a consequence, along coastal areas and low-lying river areas flooding will be expected to occur more frequently.
