For current and forecasted global ag production, see http://www.fao.org/documents/card/en/c/ca8861en http://www.fao.org/documents/card/en/c/ca8861en OECD-FAO Agricultural Outlook 2020-2029 https://www.fas.usda.gov/data/world-agricultural-production https://www.fas.usda.gov/data/world-agricultural-production Reading Gizmodo for ag is like reading AgWeb for the latest zero-day. It might be fine (the Gizmodo content on this year’s wheat crop mirrors the USDA reports cited above) but there are other sources for which it is their full time job.
