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 over-estimation 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.

The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.
