The various ecosystem services related to water form a complex structure that impacts on human well-being so it is necessary to know the relationships between their attributes to support decision making for water security. Our work investigates individual preferences for water ecosystem service attributes in the Tilacancha River Microbasin, in northern Peru, using two methods of a different nature. In that context, prioritization results using Choice Experiments and Analytic Hierarchy Process are compared for their abilities to represent purchase preferences and theoretical preferences, respectively. Both methods reveal that in a context of abundant water resources, the public has a higher preference for the attributes Quality Maintenance and Water Regulation, over Sediment Control and Water Yield, which were less valued. The differences allowed us to identify possible applications of the results useful for water security management. Additionally, we conclude that it is possible to combine the results of both methods to support decision making, and we highlight the specific cases in which it is appropriate to use the methods individually. |
