Disaster mitigation-based land suitability for settlements using Multi-Criteria Evaluation (MCE) method in The Northern Part of South Barito Regency

Abstract

Settlements are indispensable to humans as a place of residence and for other activities. Moreover, there is an increase in land requirements for settlement construction due to the high population. The development of cities and settlements in the context of SDGs needs consideration to mitigate, adapt to climate change, and resist disasters. Therefore, this study aims to identify, analyze, and describe disaster mitigation-based land suitability and availability for settlements in the Northern Part of South Barito Regency. The method used was Multi-Criteria Evaluation (MCE), while the inclusion criteria are slope, soil type, rocks, drainage, soil texture, elevation, land use, and distance to the rivers. Each criterion was weighted using an AHP, while scoring and map overlaying were carried out using a GIS to determine the class of land suitability. The flood hazard map was used to obtain the area of free flooding. The results showed that actual land suitability for the most extensive settlements is in the S2 (Moderately Suitable) class. Meanwhile, the land that is used without flood hazards is approximately 18.9% of the Northern Part of South Barito Regency landmass. This analysis is used as consideration by policymakers to develop spatial planning in South Barito Regency.
