    Economic assessment of the environmental services of PNA Cerro Mohinora, Guadalupe y Calvo, Chihuahua by García García, Samuel A., Alanís Rodríguez, Eduardo, Aguirre Calderón, Óscar A., Yerena Yamallel, José I., CUÉLLAR-RODRÍGUEZ, Luis G., Alejandro Collantes Chávez, Alejandro, Rascón Solano, Joel

    Published 2023
    “…The objective was to determine the willingness to pay (WTP) by the visitors through the Contingent Valuation Method (CVM) in order to conserve the environmental services (SA) provided by the area and to know their perception of the current state of the Hill. 210 surveys were carried out to simulate a hypothetical market, where they asked what is the maximum amount they would be willing to pay to preserve and/or improve the SA of the PNA. The main results show that 90.48% of the visitors gave a positive WTP, 48.57% of the visitors are local and 55.24% have a university degree. 60.48% of the visitors do ecotourism on the Hill. …”
