Abstract
El Antropoceno, caracterizado por cambios ambientales globales, como el cambio de uso y coberturas de suelo o el cambio climático, contribuye a la pérdida de biodiversidad. El concepto de servicios ecosistémicos permite comprender más en profundidad la relación humano-naturaleza, por ende, su cuantificación y mapeo es imprescindible para desarrollar estrategias de gestión y conservación de la biodiversidad a distintas escalas, de la mano de herramientas que posibiliten evaluaciones multicriterio. Actualmente, Chile carece de líneas base oficiales en materias de valoración ciudadana de servicios ecosistémicos. Al mismo tiempo, el valle central del Maule está dominado por paisajes antrópicos y degradados. En consecuencia, el objetivo del estudio fue identificar sitios de alta provisión de servicios ecosistémicos en la provincia de Linares. Los métodos consistieron en actualizar sus coberturas al 2023, mapear la capacidad de provisión de 10 servicios ecosistémicos, generar una encuesta de percepción de la relación bienestar humano - naturaleza para ponderar los servicios, y finalmente, priorizarlos espacialmente con y sin ponderar. Los resultados mostraron que la regulación de caudal y de calidad de agua son los servicios ecosistémicos más esenciales para el bienestar de las personas y que los sitios de alta provisión de servicios ecosistémicos se ubican principalmente en la zona precordillerana del área de estudio. Se concluyó que el estudio representa una contribución directa a la sustentabilidad del territorio, destacando que los bosques nativos y los cuerpos de agua merecen especial consideración en políticas públicas para garantizar la provisión continua de múltiples servicios ecosistémicos en el largo plazo.
The Anthropocene, characterized by global environmental changes such as land use and land cover change or climate change, contributes to biodiversity loss. The concept of ecosystem services allows for a deeper understanding of the human-nature relationship; therefore, its quantification and mapping are essential for developing management and conservation strategies for biodiversity at different scales, alongside tools that enable multicriteria assessments. Currently, Chile lacks official baseline data on citizen valuation of ecosystem services. At the same time, the central valley of Maule is dominated by anthropogenic and degraded landscapes. Consequently, the study aimed to identify sites of high provision of ecosystem services in the Linares province. The methods consisted of updating land cover to 2023, mapping the provisioning capacity of 10 ecosystem services, generating a survey on human-nature well-being perception to weigh the services, and finally, spatially prioritizing them with and without weighting. The results showed that flow regulation and water quality regulation are the most essential ecosystem services for human well-being, and that sites with high provision of ecosystem services are mainly located in the pre-Andean zone of the study area. It was concluded that the study represents a direct contribution to the sustainability of the territory, emphasizing that native forests and water bodies deserve special consideration in public policies to ensure the continuous provision of multiple ecosystem services in the long term.
