Land-use problem and controling for sustainable coastal development in South Bali

Land-use development in the coastline areas due to tourism activities leads to indications of the spatial significant discrepancy because it is not in line with the spatial planning and does not pay attention to aspects of disaster mitigation. Therefore, it is essential to maintain the coastline area that used as protection and public space. Although several previous studies have been conducted, there are still many spatial violations. This study analyses the level of land-use suitability in the coastline area and formulates strategies for land-use control following the spatial plan. The study employs Geographic Information System (GIS) by overlaying the land use map in 2022 with the regional spatial plan of Gianyar Regency. Here, the data analysis used a matrix of the Internal Factor Evaluation (IFE), the External Factor Evaluation matrix (EFE) and the Internal External Matrix (IE). The results show that 171,427.62 m² (92.08%) of the existing coastal land use is in conformity with the spatial plan. Meanwhile, there is 14,750.09 m² (7.92%) of the total study area that is not conforming with the spatial plan. Strategies that can be carried out in efforts to control land-use are intensifying the socialization and supervision of land-use control, preparing detailed the spatial plans, implementing incentive and disincentive programs to relevant stakeholders, and strengthened in enforcing regional regulations regarding the spatial plan of the Gianyar Regency.
