Valoración Económica de los Servicios Ecosistémicos del PNN Tayrona Mediante los Métodos de Valoración Contingente y Costos de Viaje Como Aproximación al Valor Económico Total

Abstract

This research aims to determine the ecosystem services provided by the National Natural Park Tayrona and thus, to construct an economic valuation for the same, through the application of two complementary methods that value both regulatory services, of supply and support. For the contingent valuation, a multiple linear regression was used, estimating the DAP (Availability to Pay) at COP 26099.005 per person, complemented by a logistic regression to improve the accuracy of the data. In the Cost of Travel method, a Poisson regression was used to obtain the necessary coefficients and in this way to assess the direct use of PNN Tayrona, yielding a value of 1,632,572,895,737 COP. The development of this project derives from the identification of the problems presented by the PNN Tayrona due to the great influx of visitors which impacts on the different ecosystems present by the misuse of this one. Based on this, secondary information was analyzed to identify ecosystem services, after which a first visit was made in May 2016, a survey was applied to gather information, and through those results a tool was generated to collect the necessary data In the field, which is the starting point for the design of the definitive tool for the collection of information, to generate a reliable database in order to make the statistical and econometric analysis necessary to propose an economic value of the ecosystem services that Provides the PNN Tayrona. The intention of this project is to contribute in the economic evaluation of the natural resources present in Colombia, since of a correct analysis are also emanating environmental, social and sustainable policies.
