Bali needs twice as much water as it has underground
At Bali Climate Week on 11 September, a representative of the Bali Net Zero Emissions Coalition gave the numbers: Bali needs 4.06 billion cubic metres of water a year, but only 2.07 billion is available as groundwater. More than 90% goes to farming, fisheries and plantations.
For Denpasar and Badung the main risks are urban flooding and tidal inundation on the coast. For Buleleng, north Karangasem and Klungkung it is drought and coastal erosion. Projections show parts of the coast could be under more than two metres of water by 2045.
What it means for buyers: when choosing a plot, ask where the house gets its water — a well or the mains — and whether the site floods in the rainy season. For homes right on the shore, check how far they are from the tide line.
