ollowing last month’s devastating flooding that killed 18 people, the Bali administration is intensifying efforts to prevent further disasters as the rainy season nears.
Governor I Wayan Koster said the provincial government is currently mapping flood-prone areas and conducting a land-use assessment along four major riverbanks across the island, namely the Ayung, Badung, Mati and Unda rivers.
“We will replant trees along the riverbanks and carry out rehabilitation efforts to improve water flow and reduce the risk of flooding. We will also take firm action against buildings that violate spatial planning regulations in these areas,” Koster said on Wednesday, as quoted by Kompas.com.
He added that local communities would also participate in the flood mitigation efforts by helping clean the rivers, prevent waste from entering waterways and planting trees in water catchment areas.
