Soluciones Basadas en la Naturaleza (NbS) para la Mitigación del Riesgo de Movimientos en masa: Estrategias de Implementación en la vía Catacocha-Playas

Abstract

Abstract:The Catacocha-Playas road section is an important corridor in the province of Loja; however, it presents a high susceptibility to mass movements that generate human losses, closure of strategic routes, and recurring environmental damage. The study addresses this problem with the objective of proposing mitigation strategies for the Catacocha-Playas road through the design of Nature-based Solutions (NbS). The methodology employed a mixed-methods approach with a descriptive-applied scope and a non-experimental design, developed in three phases: first, identification of critical zones through GIS analysis, integrating data on slopes, land use, and the surveying of 47 georeferenced points in the field using the GeoTraker application; second, a systematic review of international and national NbS experiences focused on roads; and third, the formulation of a sector-specific technical proposal. Bioengineering measures were proposed, such as revegetation with native species and green drainage systems. It is concluded that the implementation of these strategies is technically and environmentally viable, offering a resilient alternative to traditional gray infrastructure to reduce geodynamic risk.
