“…Although the random sampling approach is acknowledged as a prevalent practice for the elicitation of stated preferences for the WTP, the biases derived from the assessment in a random ordering reorient the selection of the target groups (Xenarios and Bithas 2008). It has been repeatedly noticed that the limited knowledge of a random sample of respondents has caused sound ecological services, fancy eco-activities and sentimental loading for future generations to be overvalued.…”

To achieve a good ecological status as proposed by the European Water Framework Directive (WFD; 2000/60/ EEC) large investments from urban wastewater authorities are required. The Directive anticipates that cost-effective plans and their economic benefits will offset the high costs required for wastewater upgrading projects. However, urban waste water authorities claim that cost-effective measures are already in place and that little improvement can be made. Current valuation studies have focused either on ecological elements or economic aspects without offering persuading evidence on the cost versus benefits of upgrading projects. To this aim, the current study developed an ecological-economic valuation framework for the comparative assessment of the ecologically sustainable levels in receiving waters and the associated economic effects. The central Wastewater Treatment Plant in Athens (Greece) and the small treatment plant in Vils (Austria) are used as representative case studies.

“…Rejman (2007) critically analyses the efficacy the WFD for the improvement of groundwater. Xenarios and Bithas (2009) discuss the constraints that the good ecological status objective imposes on wastewater authorities. Hanley et al (2006) and more recently Martin-Ortega and Berbel (2010) discuss some of the problems regarding the assessment of the non-market environmental benefits of the WFD.…”

The aim of this paper is to contribute to the still scarce literature on CostEffectiveness Analysis (CEA) in the context of the EU Water Framework Directive (WFD) in water scarce areas illustrated through a case study in Southern Spain. CEA is the preferred method to select policy measures to achieve the good ecological status of water bodies as prescribed by the WFD. It generates a ranking of the measures, according to the ratio between the equivalent annual cost and the reduction of impacts, to select the measures to be included in the Program of Measures (PoM). Here, the water-saving measures discussed in the public participation process for the elaboration of the PoM for the Guadalquivir River Basin are analysed using CEA. A methodological approach, including uncertainty for cost and efficiency of measures is proposed. A comparison between pressure and impact analysis of the effectiveness of measures shows that, in the context of the WFD, CEA should be based on the impact of the measures rather than on the pressure reduction, as the latter can lead to a misleading ranking of the water-saving measures.

The European Water Framework Directive (WFD) requires the good ecological status of surface water bodies, which implies the improvement of both their physicochemical condition, as well as their flow and continuity. The WFD prescribes the assessment of environmental and resource costs and benefits associated with implementing these improvements. The recent literature focuses almost exclusively on the assessment of the economic values related to quality aspects. However, in much of southern Europe, fulfilling the WFD goals will greatly depend on maintaining sufficient water flow, as well. This study aims to fill this gap by assessing the non-market value of allocating enough water to the environment to ensure environmental services are sustained when water is scarce. The non-market value of guaranteeing water supply for secondary household uses is also estimated. Using the Guadalquivir River Basin in Spain as a case study, a choice experiment is applied with scenarios characterized by varying water flow levels and accompanying environmental impacts, and a different frequency of household water restrictions. The results show that the population derives significant benefits not only from the direct use of water, but that also holds non-use values related to the ecological status, although the latter has a considerably lower impact on consumer surplus. Additionally, we conclude that the costs of implementing the water saving measures currently included in the Program of Measures seem to be proportionate to its benefits in this case. © 2011 Springer Science+Business Media B.V
