By the way, the article you list above is precisely the reason that migrants destroy their identity papers before they take off for the Canaries.

I hate to be flippant (translation I enjoy being flippant), but if European countries were interested in limiting migration, they would pay for censuses in African countries.  And offer development aid in exchange for creating a Europol database that contained this information.  

That way you could end the very serious problem with abuse of this article of international law, which in the end undermine the protection it creates for actual cases of denaturalization of citizens by regimes that violate human rights.
