Zusammenfassung: | Geopark is a park area that is included in a conservation area, which has elements of geodiversity, biodiversity, and cultural diversity. It has aspects in education as knowledge earth science and tourism. One of the geoparks on the Java island that concern the government is the Ciletuh Geopark. Besides the potential, the Ciletuh Geopark landscape also has threats such as floods and droughts that can disrupt its ecological function. Therefore, it is necessary to conduct a study related to the wetness status of the Ciletuh Geopark to minimize the impact of floods and droughts. One way is by using the Normalized Different Wetness Index (NDWI). This study aimed to analyze the level of wetness of the Ciletuh Geopark with the Normalized Different Wetness Index method obtained from Landsat images. The results show that compared to 2001, the area with moderate wetness and high wetness decreased almost 50% in 2015, and the non-water body increased twice. On the other hand, the wetness condition did not significantly change between 2015 and 2021. The decreasing the wetness condition suspected by drought due to global climate change. |
