Usando imágenes satelitales de alta resolución, este artículo evalúa si la delimitación de las áreas protegidas que convergen en inmediaciones de la Sierra Nevada de Santa Marta han prevenido la deforestación, la presencia de asentamientos poblacionales y la infraestructura vial. Las características de las tres áreas de protección (Línea Negra, Resguardos Indígenas y Parques Nacionales Naturales) y la protección ocasionada por el traslape entre estas, son una oportunidad única para evaluar el efecto marginal de las mismas. Con el fin de identificar efectos causales se utilizan regresiones discontinuas, las cuales permiten comparar pixeles a lado y lado de cada una de las fronteras de las áreas protegidas. Los principales resultados muestran que mientras que la Línea Negra no tiene ningún efecto, los Resguardos Indígenas y los Parques Nacionales Naturales han reducido significativamente la deforestación y los asentamientos poblacionales. ****** ABSTRACT: Using high resolution satellite images, this paper assesses whether protected areas surrounding the Sierra Nevada de Santa Marta have reduced deforestation, population settlements and roads. The characteristics of the three existing types of protection (Ancestral Indigenous Area Línea Negra, Indigenous Reserves and National Parks), and the protection levels resulting from their overlapping provide a unique opportunity to evaluate their marginal effects. To this purpose, we use regression discontinuity methods, which allow comparing pixels on both sides of the protected areas’ borders. Our main results indicate that while the Línea Negra limit has no detectable effects, Indigenous Reserves and National Parks have effectively prevented deforestation and population settlements.
