AJSTD 36(2) cover


Land Suitability; Housing; Pesisir Selatan Regency


The increasing number of residents has an impact on the increasing need for living space. The diverse environmental conditions of the land cause impossibility for developing housing in every location. Therefore, spatial analysis is needed to determine land suitability for housing development to avoid environmental problems. The aims of this study were determining the projected land needs for housing and doing suitable area mapping for housing through spatial analysis using 5 physical parameters (slope, disaster vulnerability, river and beach border, and protected areas). The results show that the land needed for housing in Pesisir Selatan increase every year. By 2020, it is predicted that the land allocation for housing would be 15.6 km2 – 51.15 km2. Based on the spatial analysis, the area which had high suitability (S1) for housing was 21.657%, the moderate suitability (S2) was 18.616%, low suitability (S3) was 6.782% and not suitable (N1) was 52.944%. It is predicted that in 2020, the government has to use the low suitability area although it has a more significant risk. Therefore, it is necessary to pay attention to the mitigation aspect and housing technique manipulation in steep slope area.
