Earthquake and Tsunami in Japan 2011 on the first place with a total damage of about 230 billion dollars. Equal cost damage of natural disaster have different impacts on economies depending on their economic power (GDP)!

The frequency and the costs of natural disaster, which are linked to the climate change are constantly increasing (storms, extreme temperature, droughts, floods...) . The global loss reached 375 billion dollars in 2011, which equals about 0.5% of the global world product.

Over the 20 last years about 2/3 of the world population were exposed to natural disaster. Most of them are affected by floods and droughts. 1.3 million have been killed, whereas far most of them by earthquakes.

Most of the shown natural disaster happened on islands, near the sea and at tectonic borders.  Overall loss ranges from 8 - 125 billion USD. Damage partly insured. Earthquakes, Tsunamis and Hurricane have the biggest potential to destroy facilities.

Saving water is saving lives 

Figure 1: The most important spatial pattern (the first element of the principal components analysis; top) Severity Index of the Palmer drought (PDSI) monthly from 1900 to 2002. The PDSI is a major indicator of drought measures the cumulative deficit (relative to local average) moisture to the land surface, by integrating previous precipitation and estimates of increased moisture in the atmosphere (based on atmospheric temperatures) in an accounting system hydrologique.13 The bottom graph shows the evolution of the sign and intensity of this configuration since 1900.

As you can readily see from the following World Water Pollution Map, pollution continues to be a problem, especially in industrialized nations, where a lot of pollutants are finding their way into our river's and oceans.

the increased use of water is truly impressive, and the difference between consumption and Withdrawal will increase over time. The agricultural sector is the sector that consumes the most water today and probably in the future.

A child dies every 15 seconds from poor sanitation and water supply.

1 Billion People lack access to clean water and 2.3 Billion people are without basic sanitation.

Preventable water related diseases kill more than 5 Million People every year.

Freshwater use by continents is partly based on several socio-economic development factors, including population, physiographic, and climatic characteristics. Analysis indicates that:

- Annual global freshwater withdrawal has grown from 3,790 km3 (of which consumption accounted for 2,070 km3 or 61%) in 1995, to 4,430 km3 (of which consumption accounted for 2,304 km3 or 52%) in 2000 (Shiklomanov, 1999).
