| Abstract | The population of Central Highland Vietnam steadily increased in the last decades and amount of agricultural land is scarce. Consequently, agriculture increasingly shifts towards steep sloping land of the sub-humid mountains. Maintaining productivity and creating technological options for development are therefore the most important issues to agricultural research. The objective of this research conducted in Da Nhim watershed; evaluate physical land suitability for agriculture production applying parametric method in GIS environment. Potential contributions of different conservation strategies to improve the present temperate agricultural production are also analyzed. The first step was to analyze the soil conditions, located in Da Nhim watershed. Highland soils demonstrated much variation concerning their morphological structure. The evaluation of land in term of the suitability classes was based on FAO guideline for land evaluation and quantitative analysis for land characteristics. The selection of theme layers for this study include soil group, soil texture, soil depth, slope percentage, soil fertility, mean temperature and armual rainfall or water requirement in growing period. Soil texture, slope and other soil characteristic are based on the soil map, which was established by Sub-Niapp Institute of Agriculture Planning and Projection. Spatial and attribute data were digitized and encoded in GIS database to create thematic layer. Land suitability classes are identified by matching the requirement of the land use against the characteristics or qualities of the land. Similarly, socio-infrastructure suitability map has overlaid with accessibility map (network, river, irrigation system and population density map). Agricultural environment has considered as one important factor for comprising the land and land use. The final land suitability map was based on both physical and socioeconomic suitability and proposes the land use options for sustainable agricultural production. Greater efforts should be made to develop conservation strategies in accordance with the needs of the local people and to achieve stabilization of sub-humid highland agroecosystems. For a better land use planning towards sustainable agriculture, highland soils should be further investigated and classified on a regional and local scale. Only with detailed information of the target area, adequate land use practices and selection of the right crop for the right location are possible |
