Indonesia | Announced Plans to Build a Massive Seawall to Combat Flooding Along the Northern Coast of Java

The Indonesian Government has announced plans to build a massive seawall to combat along the northern coast of Java, one of the Greater Sunda Islands located between Sumatra and Bali, a volcano - dotted island that’s at the geographic and economic centre of Indonesia, and home to more than half of its people. 

This megaproject aims to protect around 50 million residents living in coastal regions from the impacts of inundations caused by rising sea levels, an initiative confirmed by President Prabowo Subianto and reported by the national agency Antara.

The massive undertaking will be funded through a public - private partnership, with foreign investment expected to play a significant part and according to Indonesia’s National Development Planning Agency, the estimated cost stands at around US$80 billion.

The Indonesian  President said construction would begin soon, describing the scheme as part of a broader national strategy to enhance coastal resilience and ensure long - term protection from climate - related disasters.

The President during a plenary session of his cabinet said the operations include the development of  a 535 - kilometre- sea barrier to protect from a sea level rise of around five centimetres per year.

The development of this massive seawall will also play a key role in preserving about 60% of Indonesia’s industrial base, much of which is concentrated in northern Java,  as well as protecting the numerous rice fields that are vital to the nation’s food supply.
