Economic and Environmental Valuation

Resumen La investigacion se realizo en el Parque Universitario Francisco Vivar Castro (PUFVC), propiedad de la Universidad Nacional de Loja, ubicado en el canton y provincia de Loja; con el objetivo de valorar ecologica y economicamente sus bienes y servicios ambientales. Para la valoracion ecologica, se consideraron: caudales, espesor de hojarasca, diversidad floristica y faunistica, propiedades fisicas y quimicas del suelo, funciones ecologicas asignando una calificacion de excelente, bueno y malo considerando el estado actual y atributos de cada funcion. Para la valoracion economica total, se considero el valor de uso directo, usando el precio en el mercado de madera, semillas, plantas ornamentales y medicinales; y los valores de uso indirecto, opcion y existencia, mediante la valoracion contingente aplicando 100 encuestas a visitantes los fines de semana. La valoracion ecologica indica que el caudal para Leon Huayco es 5,14 l/s y Los Nogales 2,16 l/s; el espesor de hojarasca de 9,1 cm; la diversidad floristica de 137 especies; 80 especies de aves, 9 especies de mamiferos y 5 de reptiles; el suelo es franco arcilloso, pH extremadamente acido, materia organica varia de media a alta, nitrogeno es mediano, fosforo y potasio bajos. Se identificaron ocho funciones ecologicas. La valoracion economica total es de $ 641 259,50; y los aportes son: valor directo $ 626 359,5, valor indirecto $ 700, valor de opcion $ 1720 y valor de existencia $ 12 480. La valoracion ecologica-economica permitio tener una vision integral sobre el valor e importancia de los recursos naturales y genero argumentos que sustentan el manejo del Parque Universitario Francisco Vivar Castro. Palabras claves: valoracion economica, valoracion ecologica, valor de uso directo, valor uso indirecto, valor de existencia, valor de opcion. Abstract The research was conducted in the Francisco Vivar Castro University Park (PUFVC), owned by the National University of Loja, located in the canton and province of Loja; with the objective of valuing their environmental goods and services ecologically and economically. For ecological assessment, we considered: flow, leaf litter thickness, floristic and faunal diversity, physical and chemical properties of the soil, ecological functions assigning an excellent, good and bad rating considering the current status and attributes of each function. For the total economic assessment, the value of direct use was considered, using the market price of wood, seeds, ornamental and medicinal plants; and the values of indirect use, option and existence, through the contingent valuation by applying 100 surveys to visitors on weekends. The ecological assessment indicates that flow for Leon Huayco is 5.14 l/s and Los Nogales 2.16 l/s; the leaf litter thickness is 9.1 cm; the floristic diversity with 137 species; 80 species of birds, 9 species of mammals and 5 of reptiles; the soil is clayey loam, extremely acid pH, organic matter varies from medium to high, nitrogen is medium, phosphorus and potassium low. Eight ecological functions were identified. The total economic valuation is $ 641 259.50; and the contributions are: direct value $ 626 359.5, indirect value $ 700, option value $ 1720 and existence value $ 12 480. The ecological-economic valuation allowed to have an integral vision on the value and importance of the natural resources and generated arguments that support the management of the Francisco Vivar Castro University Park. Keywords: economic valuation, ecological valuation, direct use value, indirect use value, existence value, option value.
