Description
Abstract
Basins are one of the bio-geo-physical areas where the ecological processes that generate the ecosystem
services (ES) and contribute to human well-being (HWB) are more evident. They are also the physical scenario
where the nature-human interaction is more intense. The explicit relationships that link biodiversity,
ES and HWB, and the direct and indirect causes responsible for their degradation, have been rarely
explored. We used the Driver-Pressure-State-Impact-Response (DPSIR) framework to explore the relationships
between the river ecosystem and the Biobío Basin’s social system. We selected 65 basin and
regional-scale indicators to analyse the existing trends and associations among the different DPSIR components.
The trend analysis results showed major biodiversity loss and how the regulating services and
non-material goods of the HWB component deteriorated, while cultural services, direct and indirect pressures
and institutional responses increased. The relationships among the different DPSIR components
revealed biodiversity loss to be positively associated with cultural services, the material goods of the
HWB component and pressures. Indirect drivers were negatively associated with regulating and cultural
services, non-material goods and pressures. Institutional responses did not correlate with any DPSIR
component. However, these results do not reflect the complexity of the Biobío Basin’s socio-ecosystem.
We estimate that the DPSIR framework shows a corseted and reductionist vision of a greater complexity
than merely a unidirectional nature-human relationship.
