Water Security as a Public Good

One of thee clearest lessons is thee requantion of water infrastructure as a public trust and a foundational element of governance. Thee construction and construcance of canals, dams, continuirs, and aqueducts required coordinated labor, centralizazed planning, andd legal frameworks. These projects were note optional civic works but essential state functions that underpinned food decuity and social stability.
