What is food security? Well, if you ask "what's for dinner?", and what you mean is "should we eat spaghetti or rice?"; "lamb or fish?"; "potatoes: baked or mashed?", then you have food security. But if "what's for dinner?" means "where will we find our next meal?", that's food insecurity.
When teaching farmers about food security in their household, we ask them to imagine they are planning a journey. What would they need to bring? Enough food or money to last them the entire length of the stay. Well, its the same when you are staying at home. You need to plan for each day, month, year so that you have enough food to get you through. You need enough for everyday life, and for emergencies. You need seeds to plant and replenish reserves before they are depleted.
Farmers at Chifuchambewa came in large numbers to discuss food security and pick up some new tools to help them plan for the future. This community produces enough to be food secure, but the food is not available at the right time. This can all change in just a single season if farmers reserve food for lean months.
