US$80 billion plan to build a giant sea wall to save coastal areas of Java has come under fire from experts, who say the project is fiscally unviable and may become a political and environmental liability.

The megaproject, which would consume nearly half of the country’s annual state budget, may be economically sound in theory but is financially unworkable without massive government backing, according to Mamay Sukaesih, infrastructure analyst at state-owned lender Bank Mandiri.

"The giant sea wall could yield long-term returns, but not in the direct, high-cashflow way of toll roads or ports. Profits would likely come from rising land value in reclaimed or newly developed zones,” Mamay told The Jakarta Post on Monday.

“But the state must shoulder the initial development cost and build out supporting sectors before private capital is willing to follow.”

The coastal defense structure, under a plan revived last year by President Prabowo Subianto, would stretch 500 kilometers along Java’s northern coast after 15 or 20 years. The initial idea was to safeguard Jakarta, one of the world’s fastest-sinking cities, but the plan has since expanded to cover flood-prone coastal areas from Banten to East Java.

Prabowo described the sea wall as “Indonesia’s vital infrastructure project” that will be overseen by a new special authority, with construction expected to start this year.
