D. Renault: Service Oriented Management and Multiple Uses of Water in Modernizing Large Irrigation Systems

20 large irrigation systems (average system size is 171.000 ha) mainly in Asia are scrutinized for multiple uses, functions and purposes. Most of them have been investigated by FAO as part of its program on irrigation modernization. The concept of Service Oriented Management (SOM) is central in the latest developed approach, called MASSCOTE [Mapping Systems and Services for Canal Operation Techniques]. This SOM approach on irrigation systems paves the way to identifying multiple uses and functions of water services within the gross command area of these systems. Analysis shows that only two systems out of 20 can be classified strictly as single use, all the other systems, are dealing, with varying degree, with multiple water uses, multiple functions, and/or externalities within their command area and therefore can be qualified as medium or high Multiple Uses of Water Services (MUS) system. Not many irrigation systems are designed/developed for providing service for multiple water uses, or are integrating MUS in absolute terms, but not many systems rank high in service oriented management either. However many systems (7) are already following practices related to MUS, only 6 systems have low MUS integration. It is found that the higher the degree of MUS the higher the integration of SOM in the management. High SOM level goes always with high integration of any other use when practiced in the command area. For some low SOM systems integration of MUSF in the management is still made at a similar low level as the one practice for crop water services. [authors abstract]
