Vegetative conservation for landslide mitigation in bungaya sub-district, gowa regency, south sulawesi province

Abstract

Landslides disaster that occurred in Indonesia has caused environmental damage and claimed many lives. Bungaya has a high risk of landslide threat and includes areas affected by severe landslides, so landslide mitigation needs to do. Landslide mitigation is an effort to reduce the risk of landslides, which can be applied by doing soil conservation. This study aims to find out the spatial pattern of vegetative conservation to prevent landslides in Bungaya. Slope morphology and slope gradient variables used to determine the potential area of landslide, obtained from BIG in 2018 and processed by the SMORPH Method. Data of vegetative conservation variables obtained by observation and interview. Analysis that used is an overlay technique on landslide potential areas, land use, and location of landslides. The highest potential of the landslide, clustered in the southern part of Bungaya, and moderate to low potential is randomly scattered. The highest potential is in Rannaloe and the lowest in Bissoloro. In Bungaya, several types of soil conservation techniques have been carried out using the vegetative method, namely crop rotation of paddies and secondary crops. Besides, agroforestry techniques are also carried out, namely yard garden and talun-garden by planting annual crops and seasonal crops.
