Factors affecting agricultural land degradation in Bo Trach district, Quang Binh province

Abstract

We interviewed 30 agricultural officials and 80 households on land degradation. Descriptive statistics, correlation analysis, exploratory factor analysis, and regression analysis were performed on the SPSS software. Bo Trach district has 83,094 hectares of degraded land, accounting for 10.39% of the natural area, with four types of degradation: drought, salinization, erosion, and soil fertility degradation. Drought is the most severe type (40.22%), followed by erosion, salinization, and soil fertility degradation, with a share of 29.35, 36.96, and 29.35%, respectively. Five primary factors affecting agricultural land degradation in the district include (i) Land use process; (ii) Cultivation activities; ( iii) Topography; (iv) Irrigation system; (v) Climate change. The results form a practical basis for local authorities to provide orientations in rational land use and sustainable protection of land resources.
