Table 3. Adaptation in the context of an integrated water resources management (IWRM) system. IWRM component Implications for institutional adaptation Implications for water management Physical integration Increased sunk costs Increased information costs Inability to decouple the physical system   Sectoral integration Increased bargaining costs for adaptation Higher number of adversarial players in negotiations Increased information needs Inability to include new players in process Difficulty in reaching consensus Restricted ability to change system operation   Institutional integration High monitoring costs Increased coordination costs Restricted ability to change system operation
