Abstract

The increaseness of development and agricultural activities will become a very
significant contributor towards landslide and soil loss. The aim of this study is to analyse
the landslide prediction and rate of soil loss as related to landuse changes in Perlis. The
study area; Perlis is covered with 77.4% agriculture, 18% of forest, 3.2% urbanization
and 1.5% water bodies in 1999. However, during the year 2015; the agriculture area
and forest decrease to 62% and 15% respectively. Meanwhile, urbanization increase to
19.5% and water bodies 2.03%. These two results fi-om image classification were then
simulated using LandslideSim to evaluate potential area of landslide. Based on the
evaluation indicates that no area in Perlis potential of landslide. However, the rate of
soil loss in Perlis increase fi-om year 1999 to 2015. Where the higher rate of soil loss in
Perlis in 1999 is 3.86% and increase to 4.76% in 2015. These show that landuse changes
had gave a big impacts towards rate of soil loss. This statement is showed in correlation
analysis between forest, agriculture, urbanization and water bodies with rate of soil loss.
Forest and agriculture area have a strong negative correlation with soil loss which show
high correlation value ( R 2 = 0.9905 (forest with rate of soil loss) and R^=0.9778
(agriculture with rate of soil loss). Meanwhile, urbanization and water bodies area have
a strong positive correlation with soil loss which show high correlation value (R^=
0.9973 (urbanization with rate of soil loss and R^=0.9619 (water bodies with rate of soil
loss). These result indicates that changes of land use especially when vegetation area
decrease and urbanization area increase are linear with the soil loss in Perlis.
