摘要：The EU Water Framework Directive (WFD) copes with several problems related to the costs of water services, the protection of water and its efficient management. This paper focuses on some inconsistencies that may arise between the objectives of protecting the resource and of covering the costs of water services, and between the goal of full recovery of the costs and the efficiency in the use of water. This paper proposes a scheme for payment of irrigation water that does not ask farmers to pay for some of the inefficiencies arising in the water distribution service. These inefficiencies can be generated in the systems managed by Water Users Associations as a result of underutilization of the facilities. This payment scheme also provides an element that varies depending on the levels of water use. Thus, it encourages farmers to assess the effect of their production decisions on the costs of water distribution. The analysis applies this scheme to the case of an Italian Water User Association. This has been done taking into account the operational costs of the irrigation supply by means of an estimated translog cost function which is articulated according to the technological characteristics of the water distribution system.
