Post peak oil, three unconventional localized mediums of energy and/or logistics might be: coal (trains and electricity), camels (dryland or highland logistics, and dairy), and conduits (liquid, gas and electrical, Haber-Bosch process, etc). For unconventional localized food security, consider tubers (sweet potatos, yams, artichokes etc.) and taproots (carrots, beets, radishes), in addition to neglected cereal varieties and dairy products.
