Malaysia likes other Asian countries has experienced rapid urbanization due to economic development, industrialization, massive migrations as well as natural population growth. This expansion particularly the unplanned has impacted negatively on farming activities and creates huge pressure arable agriculture areas. Thus, identification of potential sites for future urban development should become important issues in ensuring sustainable development. Therefore, the aim of this paper is to use GIS based multi criteria evaluation technique to identify potential areas for urban development at Balik Pulau, Penang. The study quantified spatial and temporal dynamics of land use/cover changes and identified potential areas for future development. The results indicated that large proportions of agriculture areas had been converted to built-up areas.. Urban areas increased from 1793.2 ha in 1992 to 3235.4 ha in 2002 and became 3987.8 ha in 2010. On the other hand agricultural land decreased from 6171.3ha (53.8%) in 1992 to 3883 ha (35. %) in 2010. The study, then, produced map showing potential sites for future urban development. The findings also indicated built-up areas would continue to encroach into flat available agricultural land which will be diminished if no restriction imposed. Thus, the information obtained from this study is useful for planners and decision makers in controlling agriculture areas and guiding new development properly.
