Rookie question: Are there parts of the world that don't have IFR service
such as Africa and Siberia etc? If so, what does one do if you must fly
and
IFR conditions prevail?

Depends. It's not out of the question that, absent radio navaids or ATC
control, one might just use a GPS. In the US, it's legal to fly IFR in
Class G airspace without the benefit of a flight plan or ATC clearance.
Presumably in even more remote areas, that's allowed as well (assuming no
other impediments to aviation, of course). Even a handheld GPS would
provide accurate enough information for an IFR flight 95% of the time or
better, assuming proper preflight planning.

One could also accomplish the flight the way they did in the old days: basic
instruments and dead reckoning. Of course, in the old days those instrument
flights weren't successful nearly as often as they are today. But I suppose
if you MUST fly, that wouldn't be so much of a concern.

I'm having a hard time imagining a situation in which one MUST fly. But it
seems to me that in such situations, one wouldn't worry too much about the
legalities, and might not worry that much about the safety aspect either.
