1 Lecture 6: Surface water and flooding 2 One billion people – one sixth of the global population, the majority of them among the world's poorest inhabitants – are estimated to live today in the potential path of a 100- year flood and, unless preventative efforts are stepped up worldwide, that number could double or more in two generations. Floods presently impact an estimated 520+ million people per year worldwide, resulting in estimates of up to 25,000 annual deaths, extensive homelessness, disaster-induced disease, crop and livestock damage and other serious harm. UN says unsustainable land use and other human actions aggravate the situation. The greatest potential flood hazard is in Asia. Every year for the past two decades, more than 400 million people on average have been directly exposed to a flood. Between 1987 and 1997, 44% of all flood disasters worldwide affected Asia, claiming 228,000 lives (roughly 93% of all flood-related deaths worldwide). Economic losses in the region in that decade totaled US $136 billion. Lecture 6: Surface water and flooding 3 Lecture 6: Surface water and flooding More than just water damage!
