“…The steepness and length of a slope are critical factors that control surface runoff and erosion (Bryan & Poesen, 1989 ). The results of various experiments and observations in the field also proved that the slope degree steepness is one of the major factors leading to soil erosion (Holy, 1980 ). The higher degree of steepness will increase the surface runoff speed.…”

Soil is a fundamental resource with its value vital to the world’s ecosystem. Due to the fact that soil is one of the bases of all terrestrial life, humans cannot survive without it. However, soil erosion has jeopardized soil sustainability and affected the environmental quality, leaving a bad impact if these issues were not tackled at an earlier phase. Many research has been done to predict soil erosion susceptibility areas using different methods. This research aims to classify the contributing factors of soil erosion according to the risk and generate a soil erosion risk prediction map in Cameron Highlands. Thus, this research focuses on a knowledge-driven method that uses Analytical Hierarchy Process (AHP) technique to achieve the objectives. This technique consists of weighing the factors adopted by comparing pairs of factors that control erosion in this area through experts' opinions. 15 factors have been chosen to build the prediction map. Result shows that rainfall erosivity is the main factor contributing to soil erosion in Cameron Highlands which is 0.110, followed by land use (0.095), slope steepness (0.089), soil texture (0.079), NDVI (0.079), TWI (0.072), slope length (0.065), slope aspect (0.064), slope altitude (0.062), SPI (0.061), lithology (0.060), slope curvature (0.054), drainage density (0.049), distance to road (0.029) and distance to stream (0.025). The west part of the study area was exposed to a high risk of soil erosion. This research will give the decision-makers, policymakers and planners insight into minimizing the soil erosion problem and suggest better precautions and solutions to overcome this severe environmental problem in the more advanced phase.

“…Depending on its severity, erosion can be categorized as a natural or accelerated process (Holy, 1980 ). Favis-Mortlock ( 2002 ) stated that the natural soil erosion process has occurred since the first soil development, which happened approximately 450 million years ago.…”

“…Em escala global, a erosão eólica não é um problema tão sério quanto a erosão hídrica (Holy, 1980;WRI, 1992;WRI, 1993), mas é um processo que afeta muitas regiões áridas e semi-áridas. Assim como a erosão hídric� a eólica envolve a remoção de partículas pelo movimento de um fluido.…”
