Adherents of the back-to-the-land movement inspired by Helen and Scott Nearing, sporadically popular in the United States in the 1930s and 1970s (exemplified by The Mother Earth News magazine), share many of the same interests in self-sufficiency and preparedness. Back-to-the-landers differ from most survivalists in that they have a greater interest in ecology and counterculture. Despite these differences, The Mother Earth News was widely read by survivalists as well as back-to-the-landers during that magazine's early years, and there was some overlap between the two movements.
The kind of gear you need – It’s easy to get obsessed with survival gear and start accumulating every new product that comes on the market. If you have money to burn and engage in a variety of backcountry activities this might be a sound strategy. Most people however decide pretty early on what type of outdoor activity floats their particular boat and as such any survival gear should have some sort of relationship to that activity. Everyone, for instance, should have an emergency whistle with them but not everyone will need an extreme sleeping bag. Everyone will need first aid items but not everyone will need to carry croval shovel or a tactical watch or field watch. If you’re a mountaineer you’ll probably want that shovel, especially if you’re climbing in the winter. If you’re going on a day hike and aren’t bringing food that requires preparation there’s no need for a mess kit and so on.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
