Abstract:
The sharply contrasting ways in which community irrigation schemes in New Zealand were developed and managed before and after 1990 illustrate the operation of decentralised vis-à-vis centralised (planning) industry governance systems. While the evidence is not easily quantifiable what evidence there is suggests that the shift to a decentralised system that took place about 1990 coincides with improved irrigation efficiency. NZ irrigation thus provides an example of the global move away from centrally planned systems and illustrates the important elements of well functioning decentralised systems. Today farmer owned companies - rather than State owned - are responsible and accountable for scheme development and management. In combination with the RMA - which enables a decentralised approach to resource use - this has facilitated innovation in scheme design more efficient management and better water use. It has also revealed more precisely the value of water in irrigation.
