In this talk, Allan Savory invites us to a journey of reeducation and discovery on how to fight desertification and reverse climate change.
“Desertification is a fancy word for land that is turning to desert, and this happens only when we create too much bare ground. There’s no other cause. And I intend to focus on most of the world’s land that is turning to desert. (…)
But I have for you a very simple message that offers more hope than you can imagine. We have environments where humidity is guaranteed throughout the year. On those, it is almost impossible to create vast areas of bare ground. No matter what you do, nature covers it up so quickly. And we have environments where we have months of humidity followed by months of dryness, and that is where desertification is occurring.
Now you’re told over and over, repeatedly, that desertification is only occurring in arid and semi-arid areas of the world, and that tall grasslands like this one in high rainfall are of no consequence. But if you do not look at grasslands but look down into them, you find that most of the soil in that grassland that you’ve just seen is bare and covered with a crust of algae, leading to increased runoff and evaporation.That is the cancer of desertification that we do not recognise till its terminal form.
What we had failed to understand was that these seasonal humidity environments of the world, the soil and the vegetation developed with very large numbers of grazing animals, and that these grazing animals developed with ferocious pack-hunting predators. Now, the main defense against pack-hunting predators is to get into herds, and the larger the herd, the safer the individuals. Now, large herds dung and urinate all over their own food, and they have to keep moving, and it was that movement that prevented the overgrazing of plants, while the periodic trampling ensured good cover of the soil, as we see where a herd has passed.
… if we do what I am showing you here, we can take enough carbon out of the atmosphere and safely store it in the grassland soils for thousands of years, and if we just do that on about half the world’s grasslands that I’ve shown you, we can take us back to pre-industrial levels, while feeding people. I can think of almost nothing that offers more hope for our planet, for your children, and their children, and all of humanity.
“As is a tale, so is life: not how long it is, but how good it is, is what matters.
I wish you all very good lives.”
