This paper surveys the past half-century of water management experiments and experience in the Indus River basin in Pakistan as a way to identify principles for long-term water planning. The survey focuses on three variables: (1) spatial scales of water management; (2) geographic regions of water management; and (3) substantive water problems. These variables help assess changes during the post-colonial transition (1947-60); Indus basin development (1960-75); and management and environmental movements (1975-2000). Taken together, these periods point toward a model of Articulated Adaptive Management, which stresses planning for economic, political and environmental crises; dynamic changes in governance; multiple scales of water management; regional diversity and innovation; and broader scientific experimentation and monitoring of water management alternatives .
