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.

“…The North central coastal region of Vietnam stretches approximately 700 km of coastline, characterized by a relatively high population density with a poverty rate greater than 10% in 2020 [22]. It is among the most climate-vulnerable regions of Vietnam [23,24].…”

“…The central coastal communities are thus grouped into different household groups: fishing-based households, agricultural-based households, and aquacultural-based households. However, due to the land characteristics of white-sand dunes with poor fertility, the communities have been increasingly more reliant on aquaculture and fisheries for livelihoods [22,25], although this level of aquaculture and fisheries reliance depends on households' livelihood sources and capacity [22].…”

This study investigated the impacts of the COVID-19 pandemic on livelihoods of households with migration workers, who returned home to the central coastal region during the peak disease outbreak in Vietnam. Five hundred and twenty-nine households with returned migration workers aged eighteen and above in the coastal areas of Quảng Bình, Quảng Trị, and Thừa Thiên Huế provinces participated in this study. Results showed that the livelihoods of all studied households were highly vulnerable due to impacts of the COVID-19 pandemic, with almost 90% at moderate or high risk according to the vulnerability index. All livelihood assets were negatively affected, and financial, psychological, and social assets were the most affected, with Common Vulnerability Score System scores of 3.65, 3.39, and 3.17, respectively. Male, younger workers, or those with a lower education level and fewer social networks were found to be more vulnerable than others. This study suggests that young laborers could aim to attain a higher level of education and/or practical skills to be able to obtain stable employment with benefits such as social insurance if they desire to out-migrate. Further, social programs which allow for migration workers at the destination to meet each other may have positive impacts on their vulnerability.

“…Even though 2 jetties at the north and south banks of the estuary are built up since 2015, the sediment process at the channel of the estuary has been still happening. The deposition of sediment directly affects flood drainage and waterway navigation as well as causing disturbance in socio-economic development [2].…”

“…The coastal area is significantly influenced by the seasonal monsoon regime with large northeast waves from October to March and calm southeast waves from April to September each year. As a result, the morphology of the entrance to Thuan An estuary undergoes dynamic seasonal changes due to the distinct variations in the direction of wave-induced longshore sediment transport between the two monsoon seasons [2].…”

Thua Thien Hue province is significantly affected by conditions of climate change and sea level rise. Located in central Vietnam, the province experiences various climate-related challenges that have a strong impact on its environment and communities. Furthermore, the complexity of hydrodynamic regimes at main estuaries is reasonably challenge for the development of socio-economic, especially in water transportation. As a large estuary of Thua Thien Hue province, Thuan An play a special role in flood drainage and waterway navigation of Huong River. Therefore, understanding the hydrodynamic regime of Thuan An estuary is crucial due to the continuous alterations in its morphology during monsoon seasons. Sedimentation within the estuary creates obstacles for the river mouth entering channel, while erosion affects the northern and southern coasts. These changes have direct implications for flood drainage and waterway navigation. To gain insights into the hydrodynamic regime, this study focuses on further interpretation the hydrodynamic regimes in Thuan An inlet using Delft3D model combined with ArcGIS tools. By combining scientific modeling and practical implications, this study contributes to a better understanding the hydrodynamics of Thuan An estuary, ultimately facilitating sustainable development and management of this vital waterway system. Importantly, proposed structure for flood drainage and navigation stability in Thuan An estuary is considered with the elongation of 2 jetties. The proposed measure shows that the flood drainage is insignificantly affected and the water level at mostly locations in the river is not changed.
