I was born in the farm but I do not have formal training on how to survive in the wilderness. While many Filipino are now lecturing about mountaineering skills, all of them focus more on hiking skills and tools needed while hiking.
The big difference in wilderness survival training is that when you go to forest unprepared. Yes you do not have a sleeping tent with you, no knife you can use to cut branches to make shelter, and yes no prepared food to eat as well cooking equipment to prepare. Furthermore, no communication with the outside world.
That is the big difference with mountaineering, they are always prepared based on their need. Here is video from American TV company featuring Travis Johnson a SERE expert and survival instructor teaching city girls the basic of wilderness survival skills.
As mentioned, the 3 most important knowledge in the wilderness is shelter, fire, and water. If you want to learn more about wilderness survival, visit the site about survival school and learn more from SERE expert– Travis Johnson.
