“Regenerative Agriculture” describes farming and grazing practices that, among other benefits, reverse climate change by rebuilding soil organic matter and restoring degraded soil biodiversity – resulting in both carbon drawdown and improving the water cycle. It involves, incorporating permaculture and organic farming practices, including conservation tillage, cover crops, crop rotation, composting, mobile animal shelters and pasture cropping, to increase food production, farmers’ income and especially, topsoil.
Only 60 years of farming left if soil degradation continues. About a third of the world’s soil has already been degraded and causes of soil destruction include chemical-heavy farming techniques and deforestation. Generating three centimeters of top soil takes about a 1,000 years.
The loss of the world’s fertile soil and biodiversity, along with the loss of indigenous seeds and knowledge, pose a mortal threat to our future survival. Without protecting and regenerating the soil on our 4 billion acres of cultivated farmland, 8 billion acres of pastureland, and 10 billion acres of forest land, it will be impossible to feed the world. Allan Savory gave a TED talk on fighting desertification and reversing climate change in 2013.
