Food production is one of the most essential concerns of any society. Without direct availability and ease of consumption, without the consistent flow of agricultural goods, every nation existing today (except the most primitive) would immediately find its infrastructure crumbling and its people in a furious panic. It’s strange to me, then, that long term independent food planning is the one concern that many Americans seem to take most for granted. Firearms and ammo, camping gear and bug-out-bags, MRE’s, beans, and rice; these are the easiest part of your survival foundation. The hard part is not storage of goods, but devising a solid and practical plan for sustainability in the long term. This starts with the capacity to support your own agriculture regardless of how long the grid is down, even if it is down indefinitely.
Understandably, there will be some people who do not have enough land to implement many of these strategies. They should still know the fundamentals and be ready to apply them at a retreat location or within a community should the opportunity arise.
