 The water-conflict chronology is an open-source online database that tracks water-related conflicts from around the world. It contains over 1,300 entries, dating back to 2,400 BCE, and provides insights into the nature, location, and social and political characteristics of these conflicts. Recent years have seen a sharp increase in water-related violence, particularly in the Middle East, Southern Asia, and the Sahel regions. Additionally, there has been an increasing targeting of civilian water systems during civil and regional armed conflicts. This article was authored by Peter H. Gleek and Morgan Shimabuku.
