James;
This is an old story but still interesting: Lost tribe bypassed by history [1].
My [Cambodian] wife, who is in her thirties, still has some of these jungle/farming skills. Her younger brothers and sisters who have lived in Phnom Penh [2] do not. Most young people only know about Karaoke and mobile phones. Many of the under 15’s think the Khmer Rouge is something their parents made up.
See:
Lost tribe leaves the jungle for brave new world of mobiles [3].
Help runs out for the lost tribe of Cambodia [4]
I don’t think most people want to copy their example. But their story does illustrate that long term survival is possible for people with skills even if they have little resources. Regards, – F.D.
