This development ultimately led to the unification of much of Mesopotamia under the rule of Sargon, the first monarch of the Akkadian

But the man-made infrastructure took advantage of some of the potential of this space (large rivers and broad, flat plains) to counter these issues and make lower Mesopotamia one of the most productive agricultural areas in the ancient world. In the north, the uncertainties of production were greater, as a result of the fluctuation of the climate year by year. There were, as a result, many systems of agricultural land, reflecting the diversity of ancient Mesopotamian agriculture. The natural context of ancient Mesopotamia was little different from modern conditions in this region,
