Wow your garden and homestead has come a long way! Love that idea of having food swaps. I never thought of having an organized one like that before. We often trade amongst our neighbors when we have excess but I see that could be a valuable way to do it if there is a collapse and food is not available through the regular chains. We have a lot of gardeners and food producers in our neighborhood.
What a shame that the Europeans caused such destruction to your country and definitely it is time to adopt indigenous food cultivation, whether it can reverse it or not remains to be seen but it is certainly is a healthier way of food cultivation for both the people and the earth.
