Received: 8 February 2019 Accepted: 19 February 2019 The Analytic Multicriteria Valuation Method (AMUVAM) was designed to value environmental assets. This method and its software allow one to incorporate all the experts’ decisions in a global evaluation matrix and assign a degree of importance (weight) to the criteria. This multicriteria decision aid methodology has traditionally been based on the Analytic Hierarchy Process (AHP) and the Discounted Cash Flow. However, it can be substituted by the Analytic Network Process (ANP). Although it involves a higher complexity, it considers all the current relationships between the different alternatives and criteria so it should be more accurate. Therefore, the aim of the present work is to value the ecosystem services of an environmental area by using both methods and compare the results. A real application has been presented; therefore, this work has been applied to the valuation of the Albufera Natural Park in València (Spain). This area is considered one of the most important Mediterranean wetlands of the Mediterranean countries. Having obtained the results, the method can be carried out using either of the two processes when the aim of the assessment is to get the Total Economic Value. In this case, the AHP can be used as a less time-consuming and cheaper method. However, if the goal is to value the ecosystem services, there are significant differences between both methods. Some of the services are overvalued or underestimated when the AHP has been used.
