Earliest Mesopotamia Food Producers Used Irrigation

This paper will show that water management can be studied for Ancient Mesopotamia on the basis of primary written sources inscribed by the very administrators who ran the water management system. This transforms our understanding of how the system worked, making it possible to provide detailed insights into hydrological engineering of 5000 years ago.

Prominent among the latter are local differences in land or labor productivity, stemming from the availability of adequate irrigation water or phenomena like salinization. Finally, it has been suggested that animal husbandry also can be a force for economic differentiation, consistently generating a flow of both wealthy entrepreneurs and impoverished laborers into the ranks of the sedentary cultivators (Barth 1961). There are, in short, a number of potentially more productive links to explore between early Mesopotamian agriculture and the emergence of the state than that which is suggested by persistent obsessions with hydraulically-based despotism.

For farmers, the study demonstrates how early Sumerians used short canals and tidal flows to irrigate crops efficiently—without large-scale infrastructure. This ancient, low-tech, high-yield agriculture model can inspire sustainable farming ...

Irrigation brought water to fields faster than it could drain out. As salt-rich groundwater rose and surface water evaporated, mineral salts built up in the soils. Farmers switched to more salt-tolerant grains like barley, but the harder they farmed, the less they harvested.

If this problem was really caused by the high salt content of the soil and their irrigation system brought a rising amount of salt-carrying water to the surface, then the ancient Mesopotamians seem to have developed techniques that ameliorated this issue: control of the quantity of water discharged into the field, soil leaching to remove salt, and the practice of leaving land to lie fallow. It is not certain that the salinisation of land in southern Mesopotamia actually did lead to a fall in output and crisis in the long-term, but it did constitute a constant year-to-year problem.
