I agree, decentralization of food production is critical to sustainable and reliable food production. Some places even have community compost centers where people bring their scraps and can get compost for their gardens. A shift in growing crops more adapted to the local climate reality is also an important shift. A lot of places grow staple crops brought by colonizers centuries ago, which are ill suited to the local soil and require additional resources to grow, whereas less known types of grain and fruit/veg could be grown to produce higher yields with less effort and be more hardy in the area's temp/precipitation/soil. Initial costs of setting up local food growth might seem exorbitant, but would bring a lot of long-term cost reduction for people. Added bonus to this is reducing pollution caused by worldwide shipments of produce, and improving food taste as things grown nearby don't need to be harvested early and ripened in route, refrigerated, treated for pests. Another thing that would be beneficial, and this is the idealist in me speaking, is giving people the empowerment to control their own food supply, boosting communities, giving people the means to have more autonomy over their basic needs so they're not reliant on a global market currently dealing with a variety of issues, mitigating the risk that food imported will be scarce or too expensive for families to feed their members.
