The study was conducted in ethnic minority and mountainous communes of Thua Thien Hue (A Luoi and Nam Dong), where fragmented terrain is prone to flash floods, landslides, and droughts. The population depends on agriculture and forestry but is highly affected by climate change. Using a research-based approach, the study assesses hazard, exposure, sensitivity, and adaptive capacity to determine vulnerability and risk levels. Very high vulnerability covers 6.82% of the area, mainly in A Luoi (74.03%), 2.85 times higher than Nam Dong. High vulnerability accounts for 21.43%, with A Luoi (82.48%) exceeding Nam Dong (17.52%) by 4.71 times. Very high-risk areas make up 4.69%, with Nam Dong (56.35%) surpassing A Luoi (43.65%) by 1.29 times. High-risk areas (13%) are concentrated in A Luoi, 2.58 times higher than Nam Dong. To reduce impacts, key measures include forest conservation, infrastructure upgrades, disaster warnings, and sustainable livelihoods.

This article aims to provide a scientific basis for solutions to use soil cover for sustainable agricultural and rational forestry development. We used traditional methods such as survey and data collection; soil profile comparison method; vegetation indicator for soil degradation; determining the physical and chemical limiting factors of the soil; combined with the application of Geographic Information Systems (GIS) technology and the multi-criteria method (MCE) to conduct a soil degradation assessment for the Thua Thien Hue province, Vietnam. In this study, nine indicators affecting the current soil degradation were selected and then the single-dimensional maps were superimposed to form the current soil degradation map for the study area at a scale of 1/10,000. The study results show that: lightly degraded soil accounts for 48.81% of the total natural area of the study area; medium degradation accounts for 22.07%; and severe degradation accounts for 19.66%. The study results show that most of the soil in the study area is at a moderate to severe level of degradation and shows the need for synchronous implementation of reasonable solutions to prevent degradation and use soil sustainably in the Thua Thien Hue province, Vietnam.
