jpnn.com, JAKARTA – Analysis results of the National Institute of Aeronautics and Space (LAPAN) show that the risk of flooding in South Kalimantan is increasing due to a significant narrowing of the forest area.
LAPAN stated that the contribution of forest shrinkage in the last 10 years had increased the risk of flooding in the South Kalimantan region.
Land cover data shows that from 2010 to 2020 there was a decrease in the forest area as a whole, reaching a total of 322 thousand hectares.
The narrowing consists of 13 thousand hectares of primary forest, 116 thousand ha of secondary forest, 146 thousand ha of rice fields, and 47 thousand ha of shrub respectively.
Meanwhile, the area of plantations in that area, according to data on changes in land cover, has an area of up to 219 thousand ha.
“Changes in land cover in the past 10 years can provide an overview of the possibility of flooding in the Barito watershed, so that it can be used as an input to support future flood disaster mitigation efforts,” said Head of LAPAN’s Center for Remote Sensing Utilization M Rokhis Khomaruddin.
In addition, the results of rainfall analysis based on Himawari-8 satellite data show that rain-producing cloud coverage occurs from 12 to 13 January 2021 and continues until 15 January 2021 in the South Kalimantan region.
“This rainfall is one of the causes of the floods that hit South Kalimantan Province on January 13, 2021,” said Rokhis.
