WARS have been fought for it, in the third world families walk miles everyday for it, we cannot survive without it. It is that most vital substance for life, water.

As the world faces an ever-increasing demand for an ever-decreasing supply, Zaragoza has chosen water as the theme when it hosts the next International Exhibition in 2008.

The subject is quite an appropriate one for a city in the second driest part of Spain, where the newspapers are filled daily with reports of the sequía (drought) and show pictures of ancient villages once flooded to make reservoirs being eerily uncovered again as water levels plummet.

ZARAGOZA, city of history

The reason for Zaragoza’s location is not difficult to find. The enormous River Ebro is the lifeblood of Aragón and, rather ironically, has the highest volume or caudal of the rivers in Spain while passing through one of the driest parts of the country.
