Assessment of land resources potentials for orientation of agriculture land use in Ham Thuan Bac district, Binh Thuan province

Land resources potential assessment is a valuable method for orienting land use planning in the world as well as in Vietnam. This study aimed to (1) assess land suitability and (2) orient the effective use of agricultural land in the study area. Results indicated that Ham Thuan Bac had 107 land mapping units (LMUs) with 11 main landuse types (LUTs) such as rice, cassava, vegetables, dragon fruit, and other trees. Agricultural land with high (S1) and moderate suitability (S2) for most LUTs was small; however, marginal (S3) and not suitability (N) lands were quite large.
