El valor del entorno rural en Aquitania (Colombia): aplicación de modelos espaciales hedónicos en el análisis de bienes raíces Resumen El presente estudio aborda el valor económico marginal de las comodidades ambientales, características estructurales, instalaciones vecinas y la accesibilidad de las propiedades en Aquitania, Colombia. Tomando como base 400 valores calculados de propiedades de terreno rural y 21 variables características de las instalaciones y comodidades del terreno, este estudio compara tres modelos: Mínimos Cuadrados Ordinarios (ols), Modelo de Rezago Espacial (slm) y Modelo de Error Espacial (sem). Los resultados muestran que tanto el slm como el sem superan al ols en la identificación de la importancia de los atributos de los bienes raíces. Los resultados muestran que los granjeros aprecian las comodidades del entorno sobre otros atributos, quedando implícito el mayor valor de la ganadería sobre la agricultura (cultivo de cebolla) en el uso del terreno. Estos modelos pueden ser de ayuda para sustentar decisiones respecto a la economía de los bienes raíces rurales. os agricultores gostam do conforto do entorno sobre outros atributos, ficando implícito o maior valor da produção de gado sobre a agricultura (cultivo de cebola) no uso do terreno. Estes modelos podem ser de ajuda para suportar decisões no que diz respeito da economia dos bens de raiz rurais.Palavras-chave: Les résultats montrent que tantôt l slm que le sem dépassent au ols dans l'identification de l'importance des attributs de biens immeubles. Les résultats montrent que les fermiers apprécient les commodités de l'entourage sur les autres attributs, de ce fait il est implicite que l'élevage a une plus grande valeur par rapport à l'agriculture (planter de l'oignon) dans l'usage du terrain. Ces modèles peuvent être d'aide pour soutenir les choix par rapport à l'économie de biens immeubles ruraux
Forest carbon sequestration is a mechanism to remove greenhouse gases. Trees, through the process of photosynthesis, absorb carbon dioxide -CO 2 from the atmosphere and store it as biomass. The objective of this study was to quantify and assess the financial viability of the generation of carbon credits in the Baturité Mountain, an area of 7,000 ha of tropical montane sub humid forest in Ceará state of Brazil. GHG reduction was estimated by nondestructive methods (based on forest inventory estimates). Economic criteria used to evaluate the project were the Net Present Value (NPV) and Internal Rate of Return (IRR). The results showed that, as a result of project activitiesin the Baturité MountainGHG emissions were reduced annually by 903,120 Tones of CO 2 . Based on prices and costs in 2013, forestry projects for carbon sequestrationarenon-viable if traded under the Clean Development Mechanism. The project is financially viable with returns under the New Zealand Emission Trading Scheme (IRR=28%) and in the Voluntary Carbon Standard (VCS, IRR=27%). This study provides methodological guidelines for economic evaluation of carbon capture projects. In the right environments and with the right financial incentives, keeping standing forests intact can provide benefits for the environment and higher economic benefits compared with other extractive uses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
