Didn't watch past the first 30 seconds ("perfect storm" did it for me)
but I see there is yet another media story saying how Sub-Saharan Africa
will be desert by the end of the century and it's all our fault.
Curious how the the authors and journalists don't seem to know that much
of the Sahara was green and fertile a thousand years ago, with quite
substantial human settlements. Until the climate changed, well before
the industrial revolution.
It's interesting to see that house sparrows are making a significant
come-back, if my garden is anything to go by, after virtually
disappearing over the past 30 years.
First of all, the whole thing is just a thinly disguised advert for
Savory's own rotational grazing system.
Second, do read the Wikipedia entry for him -
Researchers of the United States Department of Agriculture concluded
"these results refute prior claims that animal trampling associated with
high stocking rates or grazing pressures in rotational grazing systems
enhance soil properties and promote hydrological function".
Similarly, a survey article that examined rotational grazing systems,
including Savory's system, found "few, if any, consistent benefits over
continuous grazing."  These confirm earlier evidence, where a
researcher  compared short duration grazing (SDG) and Savory Grazing
Method (SGM) in southern Africa and found no evidence of range
improvement, a slight economic improvement of a seven-unit intensive
system with more animals but with individual weight loss. He found no
evidence for soil improvement but the increased trampling had led to

I'd have thought the grassland was grassland because grass is the plant t
hat best tolerates being grazed to the ground whilst being stomped and crap
ped on by ruminants. I'd bet there were other dominant plant species there
before the nomads passed through with their goats, killing and burning ever
ything but the grass.
The few bits of the UK that I've seen that had been untouched by humans a
nd grazing herds had reverted to nearly impenetrable jungle, unless trees h
ad shaded out the ground cover. Much of the rough hill land was covered wit
h forests and has turned to wet deserts when the tress were felled, now cap
able of supporting a few sheep per acre in summer.
My back garden for one. OK untouched by humans for about 40 years. It
was dark impenetrable thorn scrub under which NOTHING grew except mushrooms.
I cut all but a couple of trees down, and now its a wildflower meadow

These have now matured so the canopy prevents much undergrowth and you
can walk easily. There are some hardwoods but not as many as the
literature promises. Open rides are choked with Nettle and Bramble.
