Erosion affects 215.82 kilometres of Bali coastline, data shows

Kuta — Bali provincial data presented on October 12, 2026, showed that erosion affects 215.82 kilometres of the island’s 633.35-kilometre coastline, with 130.30 kilometres receiving coastal protection and 85.53 kilometres still untreated.

Why it matters: The figures indicate that 85.53 kilometres of Bali coastline remained without protection, while erosion at Kuta was damaging public infrastructure and areas used by local traders.

The figures were reported by Bali Post, citing the Bali provincial Public Works, Spatial Planning, Housing and Settlement Areas Agency. The report said erosion at Kuta Beach in Badung had become more concerning in 2026 amid extreme weather and strong waves.

The shoreline at Kuta was retreating by an estimated 1.9 metres per year, according to the report. Erosion had damaged public infrastructure including pedestrian paths, coastal retaining walls and areas used by local traders, JPNN Bali reported.

A separate Bali Post report on the October 11 inspection of Kuta Beach said national and local officials were reviewing coastal-erosion measures. It reported that the central government had spent Rp1.2 trillion between 2007 and 2025 to address about 130 kilometres of Bali coastline.

The same report said further work on the remaining 85 kilometres would require an estimated Rp4 trillion. It also reported a proposal for joint research with Indonesia’s National Research and Innovation Agency to monitor climate dynamics, sea-level rise and changing wave patterns.
