Abstract

Resumen: Este artículo tiene como objeto realizar una primera aproximación a la valoración económica delos costos ambientales del proyecto minero La Colosa en el municipio de Cajamarca – Tolima, mediante la aplicación de un estudio piloto (primera etapa) del Método de Valoración Contingente (MVC). A partir de la evaluación de impactos ambientales, de la cual los componentes de mayor relevancia, según su afectación, son el hídrico y el biótico (cobertura vegetal) se fundamenta el planteamiento del escenario hipotético. La encuesta para indagar sobre las preferencias de la población objetivo se realizó a una muestra piloto. Así, la primera etapa del MVC se desarrolla por medio de los modelos de regresión Probit y Logit, en donde la variable dependiente “Disposición a Aceptar el Pago (DAA)” se explica en los modelos ajustados a través de las variables independientes (pers_vivienda, bosq20 y ríos_mina). Para la muestra, el valor medio de DAA anual por hogar a pesos del año 2012 es de $5’577.464 durante la operación de la mina.
