If possible, base yourself and family in a more rural area that has clean and clear access to clean water that does not rely on too much maintenance to keep it flowing. Food rationing from the start, prioritize consuming fresh and sooner-to-spoil food items, try not cooking for individuals anymore but collective meals for efficiency of calories delivered. Be prepared for electricity to get knocked out and modern powered amenities to be inaccessible such as refrigerators if you don’t have access to means of generating electricity cheaply (such as solar panels). If possible, gardening can help ease the burden on food supplies if the conflict continued over a significant period of time. If possible, always boil water that is intended for consumption. If you still have access to fresh goods, try to engage in converting it into preserved goods, drying meats fruits vegetables, making fruit jams or pickled vegetables in sealed jars that have been boiled, also having a supply of salt and other cooking additives.
