Upgrading Nomad settlemenst

It isn't, because they're not on the list of factions able to convert. Furthermore, there are some non-convertible camps in Africa.

You can make them able to, by adding them to the list in the building at the bottom of the EBD (search for building convert_to_city - make sure you edit with Notepad++ and not with Windows Notepad). But this will only take effect on a new campaign, it won't work for an existing saved game.
