Indonesia says its giant sea wall will stop flooding. Is this climate adaptation or a costly folly?

"Indonesia plans to build a “giant sea wall”, more than 500 kilometres long, to
defend Java’s north coast from rising sea levels.

The proposal includes a large lagoon behind the colossal concrete wall, raising
significant questions about the feasibility and cost of such a giant project.

Indonesian civil society groups say the sea wall could prompt more sand mining,
degrade mangroves and affect livelihoods of fishing communities. There are
fears the project will worsen existing ecological destruction caused by
industrialisation. While desperate to avoid flooding, these groups don’t see a
wall as the solution.

Indonesia is significantly affected by climate change, often in the form of
severe and regular floods.

So, what is the best way to respond?"
