I accidentally stumbled into a documentary film on Netflix which I am sure your readers would enjoy. It is titled Happy People: A Year in the Taiga. I'm not sure if it is available anywhere else.
The film critic web site RottenTomatoes.com gives this description:
With Happy People: A Year in the Taiga, Werner Herzog and Russian co-director Dmitry Vasyukov takes viewers on yet another unforgettable journey into remote and extreme natural landscapes. The acclaimed filmmaker presents this visually stunning documentary about indigenous people living in the heart of the Siberian Taiga. Deep in the wilderness, far away from civilization, 300 people inhabit the small village of Bakhtia at the river Yenisei. There are only two ways to reach this outpost: by helicopter or boat. There's no telephone, running water or medical aid, The locals, whose daily routines have barely changed over the last centuries, live according to their own values and cultural traditions. With insightful commentary written and narrated by Herzog, HAPPY PEOPLE: A YEAR IN THE TAIGA follows one of the Siberian trappers through all four seasons of the year to tell the story of a culture virtually untouched by modernity.
Filled with really interesting survival and self-reliant information (that is not the focus of the movie) but some of the ingenuity is really interesting. Well worth the watch. Thanks, - Jim E.
