This - as most of this thread - reads like some well-crafted well put-together propaganda coming straight from some Paul R. Ehrlich type talking head of a person. Even if I would trust the data you provided, there is still the monoculture vs polycultlure in relation to fertilizer usage, job market, food security, microclimate aspects - each of which would require a separate thread. There is a whole socioeconomic ecosystem build around local farming, most post-communist countries had world-class agri systems in place before it was taken apart after 1989 (with local fertilizer production due to local beef production).
