ABSTRACT

 

The objectives of the study  is to indicate and analyze the key factors that impact on the desertification in Huay Sai Royal Development Study Center, Thailand  in order to assess the desertification risk of the site. The key factors, that impact on the desertification in the Center, comprise the climatic factor (Aridity Index), soil factor which are soil texture and soil fertility and land use factor. The study results revealed that the Aridity Index affects on the desertification risk at low level to non severe while the soil texture affects on the desertification risk in at high level. In addition, the soil fertility at  the site is at medium level to low level which influences on the desertification risk of the site at medium level to very high level. Moreover, the land use investigation shows that land use in Huay Sai Royal Development Study Center can be classified as five types e.g. community, deteriorated forest, forest which is deciduous forest, bare land and water body. Therefore, the land use factor of the site influences on the desertification risk at medium level to very high level. However, the water body was considered as the area that do not affect the desertification.
