A comprehensive look at the relationship between water and violence, and how we can move from conflict to cooperation and peace, by one of the world’s leading water expertsThe first major water war erupted around 2500 BCE, when the Sumerian city-states of Lagash and Umma fought for a century over irrigation canals from the Tigris River. A few thousand years later, both Athenians and then Spartans were accused of poisoning the water supply of their enemies, in pursuit of victory. From the ancient Sumerian, Babylonian, and Assyrian empires to the present day, access to and control over freshwater has been entwined with human conflict, violence, and war.
