YouTube. There are a lot of survivalists channels with plethora of information about building shelters, starting fires, finding wild edibles, cooking and even trapping. I'm not a survivalist, but as someone who lives in Colorado and plays in the Rockies almost every week knowing how to survive becomes pretty essential. Watching videos and trying things out on my outings is how i got started. Another fun thing you can do while you're out alone is bring a wild edibles identification guide of some sort for your area. Keeps you occupied and informs you about some pretty neat stuff growing around your camp.

The kids and I binge-watched Primitive Technology [1][2], which is an Aussie guy who goes out to his land somewhere and does everything from scratch: building various shelters, fires, pottery, charcoal. It's brilliant. (And I wrote all this before noticing a sister comment mentioned it too.)

Man vs Wild with Bear Grylls is also a favourite of my kids, although it does get a bit repetitive after a few episodes. Good to have on in the background while you're doing something else, and you can just look up if something interesting happens.

For navigation skills, find your local orienteering or rogaining club and do some events.

That's probably the best way. It may be multimedia but YouTube is still pretty much book learning. That said, lack of people doesn't need to imply difficult circumstances. Camping out by yourself for a week doesn't need to imply living off the land, etc.

There are plenty of resources on youtube, i found Primitive Technology channel quite enjoyable to watch.

as others said, youtube is great.

but take a look at permies.com and if you're interested, you can get into the permaculture movement. you can take advantage of an immense collection of knowledge.

these are some of the most resourceful people I know.
