atellite images have revealed that the Nusantara Capital City (IKN) in East Kalimantan has very little, if any, water resources to support activities in the future capital, a scientist said recently.
Laras Toersilawati, a senior expert at the Climate and Atmosphere Research Center of the National Research and Innovation Agency (BRIN), said that based on a study, the presence of high water (HW) was only 0.51 percent while vegetation water (VW) was 20.41 percent and non-water (NW) was 79.08 percent.
“Our research intended to predict the availability of water at IKN and its surrounding areas,” she told an online discussion on Thursday.
“So, we did not look only at the IKN but also at its buffer areas, such as Balikpapan and Samarinda.”
Laras said a high-water area of 0.51 percent was very negligible.
“While water is retained in the vegetation, the water could be lost if the vegetation is changed into built area,” she added.
She said that the study used images from the Sentinel 2A satellite from 2022 which were directly analyzed from Google Earth. The remote sensing method used multiband image data to predict changes in the availability of water in land surface and vegetation.
