How A Changing Coastline Impacted Ancient Mesopotamia

Описание: Ancient Sumer was made up of a network of city-states connected culturally and economically. Well-irrigated agricultural land likely lead to a food surplus creating an environment where the population could increase and society could become more complex. However, the flood cycles of the Euphrates and Tigris river systems do not match the agricultural calendar. So, without massive irrigation systems, which we know came about much later in Sumer's evolution, just how did the early city-states being to flourish? A new study looks at the affects of tidal waters from the Persian Gulf and suggests these flowing into the river valleys offered a solution to the flood cycle problem. This solution did not last, which is why irrigation systems eventually became essential to life on the Mesopotamian Plain.
