I came across those videos before and noticed the main speaker has been giving talks for many years claiming he has transformed the fertility and productivity of multiple cattle farms in the course of research, by simply increasing cattle density and intensity. Alas if there were truth to the idea, Allan Savory would not need to promote it - he could own or have franchised thousands of farms by now.
The purported enhanced stocking strategy would catch like wildfire if it were real and could at least be well documented after years of research, but there are no studies of any substance for it. There is no difficulty in implementing it - just keep more cattle than before, allow it to herd, move the herd around and presto your output increases and costs reduce - climate and environment get fixed and we all eat steak. This is not an exaggeration of the case made in the videos.
I think the theme detracts from the image of practical sustainable farming techniques, which are very real, continue to develop and have to compete in the current economy.
I absolutely agree with you regarding regenerative agriculture and moving towards a plant based diet. We have to do that so we can stop destroying the soil and can actually produce food with adequate nutrition.
With regards to intensive grazing it appears that some farms do do it and there have been some studies that suggest it does work. For instance this study (of which I've only read the abstract) seems to support the technique - http://www.publish.csiro.au/sr/SR07220
There are quite a few more studies and supporting material on this site http://www.regenerateland.com I won't pretend to have read them all but from the few abstracts that I have read it seems to be based in science.
As a vegan I don't want to see more animals being killed and eaten, however if farmers are going to keep farming then they should do it this way (and using silvopasture we need multiple approaches!). However if ensuring the survival of the planet involves using animals to do some work then I'm definitely open to it.
Something which may be of additional interest to you are Forest Gardens which seem to be pretty good at optimising a whole system https://www.agroforestry.co.uk/about-agroforestry/forest-gar.... The book "Creating a Forest Garden" by Martin Crawford is definitely worth checking out if only for the wealth of information regarding types of plants and their use.
The doubts about the technique seems warranted. On the other hand there is a simple reason why it might be true : if large herds destroyed the herbs on which these herds depend on, they would die off. So from an evolutionary point of view, it makes a lot of sense for large herds to fertilize soil. They NEED grass to thrive.
There are few simple rules to count on. The stability of grasslands depends on circumstances, usually including a range of herbivores to prevent forestation. Mega-fauna, like mammoths used to contribute to grove and prairie creation by eating trees, before humans dominated.
I wrote this to dereke in another comment, I think it is relevant to understanding the present situation:
>
Two hundred years ago about 60% of the earth surface was covered in mature and native forest. The figure is less than 30% today. Most of the worlds fertile crops are grown on deforested land, on the soil which native forests developed through ecological diversity and lack of erosion. Most of the grasslands which are used for grazing, don't have the soil quality to support demanding crops.
