Resumen
La capacidad adaptativa incide en la vulnerabilidad del sistema social y se define como la capacidad de respuesta del sistema ante una amenaza como puede ser las alteraciones en la oferta y entrega de servicios ecosistémicos (SE). El presente estudio construye un índice de capacidad adaptativa (CA) frente a la pérdida o deterioro de SE. Para la estimación de la CA se evaluaron 16 variables sintetizadas en seis categorías que previamente fueron validadas con un grupo de expertos en el tema. Las variables fueron evaluadas en diez tipos de perfiles de beneficiarios identificados en relación con los SE provisión de agua y control de erosión en la cuenca de los Ríos Grande y Chico ubicada al norte de Antioquia, Colombia. El índice se construye con ponderación obtenida en la consulta a expertos y por análisis de componentes principales (ACP) con el fin de analizar su robustez. Se obtienen dos índices por ACP y uno por ponderación de expertos. En los tres índices las variables eficiencia institucional, distribución de la información, tecnología e innovación y conocimiento ecológico local fueron los principales factores que determinaron la CA de los beneficiarios de SE. Palabras clave: Servicios ecosistémicos, capacidad adaptativa, beneficiarios, índice.
Abstract: Adaptive capacity is a factor that affects the vulnerability of the social system and is defined as the system's capacity to respond to a threat such as alterations in the supply and delivery of ecosystem services (ES). The present study builds an adaptive capacity index (AC) against the loss or deterioration of ES. For the estimation of the AC, 16 variables synthesized in six categories that were previously validated with a group of experts in the subject were evaluated. The variables were evaluated in ten types of beneficiary profiles identified in relation to the ES water supply and erosion control in the Ríos Grande and Chico basin located north of Antioquia, Colombia. The index is constructed with weighting obtained in the consultation of experts and by analysis of main components (ACP) in order to analyze its robustness. Two indices are obtained by ACP and one by expert weighting. In all three indexes, the variables institutional efficiency, information distribution, technology and innovation and local ecological knowledge were the main factors that determined the AC of the ES beneficiaries.
