Adaptation measures on the demand side include monitoring  and regulating demand, for example, water restrictions, water pricing, water saving and efficiency measures, and land management and cover change . Prolonged water restrictions and prioritising sectoral supply could result in economic losses  . Economic instruments, such as water pricing, can be effective when combined with incentives for water saving and efficiency . Water saving and efficiency measures, such as leakage repair, education and improved irrigation, could limit conflicts across sectors but necessitate technological advances and changes in practice together with a willingness to cooperate . Increased irrigation efficiency has reduced water scarcity, particularly in SEU , and occur at farm level in WCE and NEU  but come with increasing path dependency on supply and trade-offs which may not be sustainable in the long term  .
