Marco sistemático para perfilar peligros en senderos peatonales de montaña en paisajes protegidos multifuncionales

Résumé fourni par la source

Introduction: Hiking is an accessible form of outdoor recreation, but growing trail use increases exposure to environmental and infrastructure hazards in protected landscapes with overlapping recreational and traditional uses. Objective: This study developed and applied a systematic framework for profiling hazards on mountain pedestrian trails. Methodology: A systematic observational cross-sectional assessment covered 14 official short-route trails in the Peneda-Gerês region, northern Portugal. Three independent assessors recorded observable hazards, which an independent expert panel reviewed. Hazards were classified and rated for probability and consequence to obtain a semi-quantitative risk value. Results: Among 160 hazards, material hazards predominated (84.4%), particularly motorized-vehicle conflicts and signage deficiencies. Geomorphological hazards were less frequent (13.8%) but had higher risk values than material hazards (8.59 vs. 3.91; p < 0.001). Water-related features accounted for all hazards with catastrophic potential. Accumulated risk increased with trail length, elevation gain, and duration; trail configuration showed no significant differences. Discussion: The findings revealed frequent modifiable operational hazards alongside less frequent natural hazards with greater potential severity. Conclusions: The framework supports transferable prioritization of inspection, communication, maintenance, and targeted mitigation in protected mountain landscapes.
