International Water Event Database

events database

The International Water Events Database is a searchable database documenting over 6400 historical international water relations from 1948 to 2008. Events in the database concern water as a scarce or consumable resource or as a quantity to be managed.  The Events are sourced from various news articles and are coded according to country interactions.

 The database contains information on the basins and countries involved, date occurred, issue area, Water Event Intensity Scale rating, and a detailed summary of the event.  The Events Database is available in two formats:

The events are scored with the Water Event Intensity Scale Rating, which was developed as part of the Basins at Risk Project. For more information about the methodology of the database, see the Basins at Risk project page.
