I don't think buying food and stocking is a good idea if that's what you mean, the best way around this is to live below your means and add some other cash flows.
That's right. We have little experience in storing food and we don't have an appropriate equipment, so it is very likely that a big part of the food we want to preserve will go bad. The best strategy, in my opinion, is trying to find the places where we can buy cheaper food, and, of course, where we can earn some additional money.
For those of us in developing nations storing food, especially refrigerators wouldn't be possible because of epileptic power supply. Apart from perishable goods, we in Africa have a very big advantage. Africa, especially my country has the capacity to produce most of what we consume. And our lands are very fertile and the weather favorable that one can easily grow crops without many agricultural skills.
In this hard time, it is very important to avoid waste. Hence every family must ensure they only prepare food that would be consumed without much waste. Like in my house, in order to avoid waste I have domestic animals like poultry birds that feed from food remnants and we also use their droppings as manure for our small garden. When they are matured we use them as our source of eggs and meat.
