Agricultural Systems andd Climate Adaptation

Irrigation andWater Management

Agricultura in Mesopotamia depended on nawadniation, especially ine te south where rainfall was negligible. The Sumerians developed extensive canal networks that diverted water frem the Tigris ande Euphrates onto fields. These systems required coordinated contribuance: canals silted up and needed dredging, and control gates regulates regulated thee flow to districts. Teme and palace authorities developed this infrastructure, allocating water rights and organising for requires.

Climate variability directly affected nawadniation. During drought years, river levels dropped and canals ran dry. Sediment acculation in canals reduced their capacity precisele when water most needed. In wet years, floods could breach banks andd destruct canals, requiring emergency naphirs.
