Indonesia's coastal erosion crisis triggers $80bn seawall bet

Is this necessary? Will this work?

"Indonesian President Prabowo Subianto is reviving an ambitious, long-stalled plan to build a 500-kilometer seawall to try to protect communities from accelerating coastal erosion in the economic powerhouse that is Java, the world's most populous island. A September 2025 presidential regulation designated what was dubbed the "Giant Seawall" a national strategic project at an estimated cost of $80 billion. If the undertaking can surmount engineering, financial and political issues, Indonesia will have built the world's longest seawall."
