T
he government is preparing to study the feasibility of a plan to build a giant seawall along Java’s northern coast, which has the backing of president-elect Prabowo Subianto.
Coordinating Economic Minister Airlangga Hartarto said the seawall project was crucial for the country in facing climate change, particularly tidal flooding and land subsidence in the northern coastal areas of Java.
"We are preparing the study, and we will continue this," Airlangga said on Tuesday, as quoted by Antara.

The government has estimated that Jakarta could face economic losses of over Rp 2.1 trillion each year due to coastal flooding and if left unattended, this figure could swell to Rp 10 trillion annually over the next 10 years.
The giant Java seawall is to be developed in three phases, with the first involving the construction of coastal and river embankments as well as a system of pumps and dikes to create polders in the city’s coastal areas.
The second phase involves building a sea dike along Jakarta’s western coastline for completion by 2030, while the third and final phase involves building an eastern coastal dike by 2040.
