Abstract
La comuna de Santa Bárbara, en la región del Biobío y adyacente a la cordillera de los Andes, presenta como principales actividades económicas el sector silvoagropecuario y el turismo. Sin embargo, las diversas transformaciones del territorio, impulsadas por la falta de protección y expansión productiva, han afectado negativamente a la conectividad y fragmentación en los ecosistemas terrestres. Esto ha provocado una significativa pérdida de la biodiversidad y servicios ecosistémicos (SE), esenciales para la subsistencia de los habitantes. Además de las presiones antrópicas, el cambio climático ha intensificado los impactos en la comuna, lo que subraya la necesidad de desarrollar estrategias que gestionen y protejan su biodiversidad. En este contexto, la infraestructura ecológica (IE), se posiciona como una herramienta clave para mitigar el cambio climático, ya permite la protección y mejora los ecosistemas que desempeñan un papel crucial en la regulación del clima, la adaptación frente a eventos climáticos extremos, y el mantenimiento de la biodiversidad, asegurando la sostenibilidad de los recursos naturales para las generaciones futuras. El presente estudio se centró en identificar la IE actual de la comuna de Santa Bárbara. Para el diseño de esta IE, se aplicaron metodologías implementadas en los proyectos de “Planificación ecológica de la región del Maule” y “diseño de una infraestructura ecológica para la región del Biobío”, utilizando un enfoque de planificación sistemática para la conservación (PSC). Los resultados mostraron que el 21% de la superficie de la comuna, corresponden a elementos de la IE, como áreas núcleos y subsidiaras, es decir, zonas de áreas de alto y medio valor ecológico que son capaces de ofrecer una mayor cantidad de SE, y poseen un mayor valor para la conservación de la biodiversidad. Finalmente, el diseño de IE actual de la comuna de Santa Bárbara, es una primera aproximación, basada en los datos disponibles, para generar una hoja de ruta para la toma de decisiones y gestión territorial.
The commune of Santa Bárbara, located in the Biobío region and adjacent to the Andes Mountains, has silvoagricultural activities and tourism as its main economic sectors. However, the various land transformations driven by a lack of protection and productive expansion have negatively affected connectivity and fragmentation in terrestrial ecosystems. This has resulted in a significant loss of biodiversity and ecosystem services (ES), which are essential for the subsistence of the inhabitants. In addition to anthropogenic pressures, climate change has intensified the impacts on the commune, highlighting the need for strategies to manage and protect its biodiversity. In this context, ecological infrastructure (EI) is positioned as a key tool for mitigating climate change, as it enables the protection and enhancement of ecosystems that play a crucial role in climate regulation, adaptation to extreme weather events, and biodiversity maintenance, ensuring the sustainability of natural resources for future generations. This study focused on identifying the current EI of the commune of Santa Bárbara. For the design of this EI, methodologies implemented in the projects "Ecological Planning of the Maule Region" and "Design of an Ecological Infrastructure for the Biobío Region" were applied, using a systematic conservation planning (SCP) approach. The results showed that 21% of the commune's surface corresponds to EI elements, such as core and subsidiary areas, meaning zones of high and medium ecological value that can provide a greater amount of ES and have a higher value for biodiversity conservation. Finally, the current EI design for the commune of Santa Bárbara represents a preliminary approach, based on the available data, to generate a roadmap for decision-making and territorial management.
