Where can I find a map of the Indigenous Communas in Ecuador?
I'm looking to buy land in Ecuador. One of the most common words of caution that I read (both on this site and elsewhere) is a common scam where a foreigner buys some land in Ecuador, but then they realize that it's actually owned by an indigenous tribe (Communa) who didn't authorize the sale collectively, so the sale is invalid. Money is lost. You get nothing.
I want a map of all such lands, so that I can make sure to avoid a purchase if I end up looking into a property that's inside its bounds.
