And in light of recent catastrophic weather events as Hurricane Katrina, it is even all too apparent. What we colloquially call natural disasters—events that wreak great social and economic cost—are today often predictable, suggesting their impacts on society may be preventable.
Flooding from extreme weather events illustrates this point. Between 1965 and 2000, nearly half of all presidential disaster declarations involved floods. A preponderance of these occurred in a minute fraction of the nation's watersheds and counties (Figure 1). We cannot yet prevent extreme weather events from occurring. But most of what ultimately happens on the land can be affected by what we do before and after the event.
