The following video is the keynote address by Indian activist Vendana Shiva at the 2015 Soil Not Oil conference in Richmond California. Her primary theme is the destructive effect of industrial agriculture on soil, human health, water balance, climate, ecological diversity, economic inequality and world peace (as the driver of continual resource wars).
She maintains industrial agriculture is an extremely inefficient method of food production – requiring ten calories of oil for every calorie of food produced. Factory farming is only economically viable because of heavy government subsidies of oil production and the synthetic nitrogen fertilizer manufactured from natural gas. If Food Inc were required to pay the full cost of industrial farming (including the toxic effects of the chemicals they use), it would be many times more expensive than organic farming.
She maintains real purpose of industrial farming is to increase GDP by producing more commodities, when it should be to maintain soil and human health.
Prior to the industrial age, farming was as much about soil regeneration as food production. The talk particularly emphasizes the importance of “carbonizing” soil with organic matter. It cites studies showing that a two ton per hectare increase in organic matter removes ten gigatons of CO2 from the atmosphere. This also makes the soil drought resistant by improving its capacity to store water.
