How did irrigation affect the growth of cities?

Irrigation significantly contributed to the growth of cities by enhancing agricultural productivity, allowing for the cultivation of larger areas and more reliable crop yields. This surplus in food production supported larger populations, enabling urban centers to develop as people migrated from rural areas seeking work and resources. Additionally, the establishment of irrigation systems often required organized labor and governance, further fostering social structures and economic activities that facilitated urbanization. Overall, irrigation was a key factor in transforming small settlements into thriving cities.
