Land-use Conservation Assessment and Its Influence on Rainfall Erosivity Distribution

Cameron Highlands in Malaysia is about 1,000 metres above sea level with
high rainfall intensity characteristics which about 2500-3000mm annually. Massive
agricultural activities had took place on the highlands along with rapid urbanisation
process over the years. Unfortunately, those have caused soil erosion problem on
Cameron Highlands and has become eminent threat by washing away natural topsoil
over the area. There are two factors governing soil erosion which are natural and
anthropogenic. In this research, natural factor by means of rainfall or precipitation will
be considered. Rainfall intensity governs the rainfall erosivity, which by definition is
the kinetic force causing soil detachments and being washed away.
