Combating sea level rise using sea walls – is this the best & only option?

“We’re coming up with these hard engineering solutions to fight nature. Artificial headlands, seawalls … they are Band-Aid solutions. The most cautious thing to do would be to maintain proper buffer zones.”

Why people still prefer seawalls:

Rissik is sanguine about the concentration of infrastructure around Australia’s coast. “From a pathway from the beach, a local economy grows and, once that is established, it anchors people to that area and change is very difficult.”

Rissik says: “People forget and they build there again.”

Seawalls and other hard engineering methods can be very effective in stopping natural coastal processes – erosion as well as deposit. This resulting in stable coastlines, allowing people to stay and build communities. 

However, how sustainable is this with sea levels rising yearly? There comes a tie where the safer option is to retreat further inland and to establish a buffer zone between water and settlement.
