This increase is from groundwater extraction which raises the salt levels and subsides the land. Plus other effects like dams changing flows. It's been a issue since before the 70's. It's a good example of how amazing the world is getting, the internet allows salt resistant plants be developed and deployed where they are needed and the results fed back. A lot of this is not new, just the networking bit and it makes a big difference.
