Building flood resistance in Indonesia: new approaches being implemented (video)
People and vehicles stranded in floodwaters, inundated business premises, interrupted connectivity, and access to other services cut off. Does this need to be the new normal in the era of climate change in Indonesia’s growing cities? We don’t think so.
