L'eau dans le monde : la nécessité, le plaisir et les risques

Water can have various meanings: a scarse ressource, an abundant social good, an element lost by pollution and wasting, a commercial product, a source of danger. In order to better get the resource under control, its location and variability have to be studied. The strategies for exploiting the resource can then be drawn up. The water management must not be dissociated from the risk management.
