Reducing Economic Losses

From Floods and Droughts

by Curtis B. Barrett

NWS/IA

world water crisis
World Water Crisis
  • By 2010 over 50% of global runoff claimed
  • World population will increase to 10 billion by 2050
  • Water use competition is intensifying between Agriculture, domestic, industrial and energy
  • Transboundry competition for water threatens international stability (About 50% of all river basins are transboundry and involve 85% of worlds freshwater)
  • Polluted water, water shortages, and unsanitary conditions kill 12 million people per year
  • Economic losses from weather related disasters have reached a record high- $92billion in 1998.
why a water crisis
Why a Water Crisis ?

Population of the World continues to increase rapidly

Water Supply on the planet is limited

People encroach in floodplains and coastal areas

Extreme meteorological and hydrological events are

Occurring due to climate change

Water pollution contamination is escalating
