Ala Ghiri's primary export was Arak, however, the date trees needed to produce more arak are just now being replanted. So it'll be a few years before they become a major exporter. Other than that, Ala Ghiri was simply a waystation for trade with the Near East. Considering the land route is still under Garlean control, that business is dead.
Ala Ghana is the primary producer of stone, brick, quarrying, etc. While you've helped restimulate the quarrying there, they have very few workers currently and very little in the way of shelter to offer them (there's a quest where you're helping an old lady repair her dilapidated house). Their main use for that stone will be helping rebuild Ala Mhigo, which benefits Ul'dah little.
Which leaves the Saltery. There's not a lot to go on here. No quest helpers. Most of this relies on your knowledge of salt as a historical trade commodity and Lolorito's love of fine dining. A sightseeing vista mentions a duct which filtered salt from the water to make it potable (until Garlemald's magitek system made it obsolete), and there's a few item and fishing descriptions which talks about salt use and trade. On top of that, it's the only option not in a hamlet so more room for expansion, there are empty homes in disrepair in the area.
But really, the easiest way to guess the Saltery was by eliminating the first two options.
