Central Java Coastal Flooding Causes Trillions in Economic Losses

Coastal flooding along Central Java's North Coast (Pantura) has inflicted economic damage estimated in the trillions of rupiah, according to the Regional Development Planning Agency (Bappeda) of Central Java Province.

Head of Bappeda, Yusmanto, explained that the primary drivers of this severe inundation are land subsidence and rising sea levels. He noted that land subsidence in the Semarang coastal area averages 12 centimeters per year, while in Demak and Pekalongan, it can reach up to 16 centimeters annually. This phenomenon is visibly altering the coastline, with satellite imagery showing the sea encroaching on land over the years.

So if we look at the North Coast, from Brebes to Rembang, originally all are affected. But the worst are those points starting from Tegal, Pekalongan, then Semarang, Demak.

The impact is widespread, affecting the entire Pantura stretch from Brebes to Rembang. However, Yusmanto highlighted that areas like Tegal, Pekalongan, Semarang, and Demak are experiencing the most severe effects. The flooding not only causes damage to infrastructure but also leads to significant economic losses through ecosystem degradation and the disruption of local livelihoods.

So if we look at Google, there is a history on the North Coast, as it is pulled from year to year, the longer it gets, the less (land there is), then the sea advances.

While Bappeda has not yet quantified the exact area of coastal land submerged or lost to the sea, Yusmanto emphasized the substantial economic toll. The valuation includes losses from ecosystem damage, loss of livelihoods, and other associated costs, all contributing to the trillions of rupiah in damages.

The article also touches upon the immediate traffic disruptions caused by the flooding. On Friday, March 27, 2026, during the post-Lebaran travel period (H+5), the Pantura highway between Semarang and Demak in Sayung, Demak Regency, was submerged. This led to traffic congestion extending up to four kilometers as travelers heading to western parts of Central Java, Jakarta, West Java, and Yogyakarta faced slow-moving conditions.

The value is trillions of rupiah. So from ecosystem damage, loss of livelihood, loss of other things, the valuation is there, it can be calculated.
