The requirements of the Water Framework Directive (WFD) 2000/60 for the full water cost recovery have brought reactions and difficulties to their implementation, especially for irrigation water. We propose a systematic and objective methodology for the estimation of the cost of irrigation water. The application is made in a degraded Greek watershed, considering surface and groundwater resources. The main novelties of this study are: (i) the attempt to combine different approaches for the estimation of the ‘resource cost’ of irrigation water, and (ii) the investigation of the potential interaction between resource and environmental cost in order to avoid the overestimation of the full cost of water. The analysis shows that both resource and environmental costs can be high in degraded areas, and water policy is likely to affect these costs. Therefore, further analysis is needed on possible water pricing policies for recovering the full cost of irrigation water.

轻松可靠地估算灌溉水总成本的方法框架

2000/60号水框架指令（WFD）对全部水费回收的要求给实施这些方法带来了反应和困难，特别是对于灌溉用水。我们提出了一种系统和客观的方法来估算灌溉用水的成本。考虑到地表和地下水资源，该应用程序是在退化的希腊流域中进行的。这项研究的主要新颖之处在于：（i）尝试结合不同的方法来估算灌溉水的“资源成本”，以及（ii）对资源和环境成本之间潜在的相互作用进行调查，以免高估了水的全部成本。分析表明，退化地区的资源成本和环境成本都可能很高，水政策可能会影响这些成本。
