Indonesia Pitches Giant Sea Wall as Economic Transformation Project

RRI.CO.ID, Jakarta — Indonesia is reframing its planned Giant Sea Wall as the centerpiece of a broader economic transformation strategy rather than simply a massive flood barrier. Coordinating Minister for Infrastructure and Regional Development Agus Harimurti Yudhoyono argued the project is intended to reshape development along Java's vulnerable northern coast.

Speaking at the “National Policy Dialogue on Sea Level Rise” event in Jakarta, on Monday, July 13, 2026, Coordinating Minister AHY said the project should not be viewed as conventional coastal protection. He claimed the government sees this as a long-term national development initiative integrating infrastructure, urban planning, logistics and economic growth.

"It's not just another project, but a grand vision that embodies economic transformation, social transformation and sustainable national development," Agus said in a keynote speech at a national dialogue on sea-level rise.

Indonesia has promoted the Giant Sea Wall as a key response to rising sea levels and land subsidence along Java's north coast, home to much of the country's manufacturing and logistics activity.

The Minister continued by saying that the government wanted to shift public perception away from seeing the project as merely a giant seawall. Instead, the project aims to combine coastal protection with industrial development, clean water supply, public housing, transportation, groundwater management and the revitalization of fishing communities.

The minister also sought to counter concerns that the project would displace traditional coastal communities. "The spirit behind this project is to save coastal communities from what is essentially an existential threat, not to push them aside,” he said.

Agus said President Prabowo Subianto has designated the Giant Sea Wall as the top priority under his infrastructure, housing and disaster resilience agenda. The project is expected to stretch about 575 kilometers along Java's northern coastline with an expected budget of US$ 80 billion that spans 15 to 20 years.
