Ecological grazing and regenerative farming

Over-grazing prevents roots from growing deep which in turn prevents the soil from holding water from sparse rainfall, leading to drought. The side-by-side comparison of both kinds of farmland (3:08) in this video is eye-opening. 

(4:30) Some people get confused when we talk about the new ecological grazing.It was actually developed by an ecologist, a guy called Allan Savory in as it was then Rhodesia, watching those giant animal herds in the millions migrating. And you'd think that such huge numbers, disturbing and eating would degrade a grassland but he found the opposite. It was the healthiest grassland you'd ever find.

Natural sequence farming (6:40) involves holding streams back and admitting a slow steady stream of water through "leaky weirs" that then provide a constant level of hydration instead of sporadic heavy rains that erode the streambed. More about Natural Sequence farming at
