#4. The next open source frontier is the farm

Michael Tiemann brings us a story about the plight of what big agriculture is doing to farm lands, and to our food. What can open source can do about it? Tiemann first explains that, "industrial agriculture evolved around the assumption that total uniformity was the key to efficiency." But, "what if large-scale processes could tolerate medium-scale diversity, restoring the benefits of ecological diversity to improve farm health?" One open source answer that has come about so far is FarmBot, a universal agricultural tool based on 3D printing technologies that can make crops economically feasible that were not feasible before, automating tasks that are too labor-intensive for humans to do. But on a small scale, allowing for diversity where large-scale farming cannot.

Georg tells us, and we're hoping the city of Munich is listening, that the newest release of Kolab 3.3 alleviates these issues and is the fix everyone is looking for.
