Forecasting Erosion Induced Landslide Risk Level in Cameron Highlands Towards Environmental Sustainability

Abstract

The Cameron Highlands are particularly susceptible to erosion because of their agricultural and urban expansion. Numerous existing and proposed development projects in the Cameron Highlands have contributed to this scenario which risks the environment. Thus, this study uses the USLE model with a GIS application to assess the risk of soil loss in Cameron Highlands. An earlier study by PLANMalaysia and the Department of Agriculture Malaysia, which documented varying land use and land cover, yielded different soil loss risk estimates in the Cameron Highlands. Town growth and development are reflected in land-use statistics from PLANMalaysia, whilst agricultural influence is reflected in land-use data from the Department of Agriculture. Based on the findings, REDAC USM's soil loss risk level estimated that 6.72 per cent of the Cameron Highlands have a 'HIGH' risk or higher. With the use of this new soil loss risk level developed by REDAC USM, farmers and local authorities may be able to regulate present land-use habits, reduce soil loss and erosion, and promote environmental sustainability in the Cameron Highlands.
