Abstract

Karakit is located at the southern part of Banggi Island, in Kudat, Sabah. This area is important in providing marine resources and habitat for human, flora and fauna and also identified for being one of the richest area for coral reefs. The main objectives of this study are to compare coastal changes between 1970 and 2003, to classify coastal features of Karakit from aerial photo with satellite image and to identify unstable area of coastline in Karakit. SPOT 5 image with date acquisition 6th June 2003 with 10m resolution and aerial photo with date acquisition on 7th July 1970, obtained from Malaysia Centre for Remote Sensing (MACRES) and Department of Land and Survey respectively. Topographic map dated 1999 was also used as a reference for image classification. The coastline changes can be detected by using overlaying technique. Results indicate that erosion occurred in the western and southern part of Karakit over a period of 33 years, from 1970 to 2003. The rate of deposition was found in the western and southern part of Karakit, but the occurrence are less than the rate of erosion. Size of mangrove forest decreased in Karakit, where in 1970 the size of the mangrove area was 246.97 hectares but in 2003 it was 225.7 hectares. Total land cover of Karakit decreased, where in 1970 it was 737.24 hectares but in 2003 it decreased to 721.71 hectares. However, further investigation and ground truthing is needed to determine the accuracy of coastline changes in Karakit area. The outcome of this study provides useful information in coastal area management and hydrodynamics study for future researches in Banggi Island.
