Concepts of legitimacy within the context of adaptive water management strategies

This paper argues that to prevent or lessen the impact of episodic water stress within modern political economies, harnessing and tailoring emerging modes of legitimacy will play a crucial role in formulating pragmatic, solution-focused policy. In setting out a case for this position, we analyse the role which existing and novel modes of legitimacy play in shaping the boundaries and opportunity spaces for policy tool development. Central to the arguments outlined is a rethinking of the concept and practise of ‘legitimacy’ to include informal relationships between actors and amongst institutions. Legitimacy's re-evaluation is pertinent as existing demand management elements of Integrated Water Resource Management (IWRM) become increasingly ineffectual in the face of escalating water stress. This paper's focus is on the interface between IWRM and socio-political values associated with potable water. This leads us to concentrate almost exclusively on public water supply issues within developed countries. It is argued that adaptive water management techniques will play a key role in policy development; but only if strategies recognise the need to engage with the diverse range of legitimacy models which typify late-industrial societies. The paper reviews theories of state action, civic participation and sovereignty to explore, through the use of case studies, what types of legitimacy models, and what types of policy to enact these models, could be used to support strategies to alleviate water stress.
