People assume survival eating will be some paleolithic diet of tubers and animal protien . SInce yu come from a farming background I propose the following : A. find a native plant society or heirloom seed collector's group. B. throughout your home territory establish some wild gardens, planting enough for you and the various critters that assure you the food is good. A fellow by name of Johny Appleseed did this. Many native peoples have also encouraged certain food crops.
