In modern times, we have come to believe wealth springs from our financial systems, our technological advances, our well organized societies, our intelligence. But take the carbon rich topsoil out from under our feet and our food chain collapses, most likely to the point where our population, wealth, our technological development, our societal order all collapse with it. In certain regions of the world where topsoil is vanishing, this collapse is apparent, a driver of migration, poverty and social instablity.
In more developed regions, as soil and thus food quality have declined, human health and productivity have been undermined.
Regenerative small scale farming, with a focus on integrated rotational grazing and no-till cropping, is a relatively simple solution that can rapidly restore soil organic carbon and fertility.10 Biochar can play an important role in regenerative agriculture. If we are going to preserve our soils, a signficant portion of the large scale, industrialized farming we currently practice must be abandoned. As with fossil fuels, we ultimately don't have a choice. Either we can plan ahead and start modifying our agricultural practices now, or risk that we undermine our capacity to provide sufficient food for ourselves.
