This study focused on providing practical information to assess the current status of soil quality and land degradation in Quang Ninh province, Vietnam to provide more evidence on land degradation status and factors affecting land degradation in this area. The soil samples were collected and analyzed in 2020 and compared to the available data of soil analysis data collected at the Department of Natural Resources and Environment of Quang Ninh Province in 2010. The percentage of degraded land ranges from 51.70 to 90.36%. Forest land is the type with the highest percentage of degraded land with 90.36% of total forestry land area; Unused hilly land ranks second with degraded land at 87.15%; the percentage of degraded land in agriculture production land stays at 80.59%. The types of land degradation such as Condensation, Acidification, and Salinization only take place on a small area of land in the province. The cause of land degradation in Quang Ninh comes from both natural and anthropogenic causes. The main reasons can be mentioned as the terrain has a steep slope; the climate is hot and rainy; the climate change situation is complicated; and inappropriate agricultural practices. To solve the above situation, it is necessary to have solutions and integrated strategies for the rational exploitation and use of land resources. Especially environmentally friendly agricultural farming methods that are highly adaptive to climate change such as organic agriculture, circular agriculture, and sustainable agriculture.
