Food and fresh water
Desalination is cheap enough for human consumption. It can be too expensive to grow food but food can be imported.
I would actually love to see Saudi Arabia take the lead on food engineering. They might lack fresh water, but they have immense amounts of land and sun to play with.
The only alternative I can see is a mass reforestation project.
Properly scaled up, this type of community reforestation effort could work.
