Apparently these games (there were more than just the Sahel one) weren't originally Danish. I've found a website of a German company producing these games:

However, they still appear to be using them at schools - believe it or not. And if I read their price list correctly, they charge €50.00 per game. OMG Well, they're probably only meant to be bought by teachers for a whole bunch of students. But still...
So they're not abandonware and can't be uploaded here, I'm afraid. I suppose your best bet would be to have a nice chat with your old geography teacher and ask him whether you might get a copy.
