Leveraging recent developments, I believe we can build small-scale farms that are low-labor and low-water-usage that grow enough chickens, fish, and vegetables (not sure about grains) to feed many families. Small scale meaning less than 1 acre and low labor meaning it does not take over your life. A gentleman’s farm that actually feeds a community.
This can bring us healthier food and lifestyle as well as a sense of food security. Serving as a model and example for others in case of a food shock, some bottom-up research and development could help society in the case of need.
I wrote an essay about my researching the subject.
