summaryLong: Irrigation is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures worldwide. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation.
lede: Around 9000 BCE, Mesopotamian societies developed the first large-scale irrigation systems, channeling water from the Tigris and Euphrates rivers to transform arid land into productive farmland. This engineering feat allowed populations to grow reliable food surpluses in a region with unpredictable rainfall, fundamentally reshaping how humans could settle and organize themselves.

impactStatement: The irrigation systems of early Mesopotamia represented humanity's first major attempt to engineer the environment at scale. By controlling water flow, Mesopotamian societies unlocked agricultural surplus, which enabled permanent settlements, population growth, craft specialization, and eventually the emergence of cities and centralized governance—the foundations of civilization itself.
