Alex I began answering but it disappeared – old age and computers mix about as well as oil and water ! Trying again.
I am not sure I understand your question. “Is there a way to use vegetation that equals the power of soil building that your method has?”
If you mean by this is there a way of using plants and technology instead of animals – i.e. planting trees, shrubs, grass and or laying lots of dead plant litter on the ground (none of which can be done without the use of energy and technology in some form) – then no, I am not aware of any method that comes close to what people can do using livestock properly managed to reverse desertification. Remember reversing desertification alone is not adequate – it needs to be done in a socially, economically and environmentally sound manner both short and long term.
Such methods (using labour, money and technology to restore plant growth) work well producing more food more reliably at lower cost, etc. where humidity is reasonably distributed as in the green zones or regions of the world I drew attention to in my TED talk. Regions where desertification is not occurring. However over most of the world with seasonal humidity where the large masses of herbivores developed with the soils and vegetation, and where desertification is occurring, I have not seen it equal what can be done mimicking nature with animals. I have seen, and of course heard of, projects in such areas showing very impressive results planting various species and laying litter with or without terracing or water harvesting measures. However analyzing such projects holistically, as we can now do using the holistic framework, always brings a fuller picture to light – and of course raises the question why did the plants need to be planted, the terraces need to be made, the water need to be harvested or the litter be laid with mankind’s help now but not in the past? In other words throws up the fact that symptoms are being addressed at high cost (money, energy and labour) and not the cause of desertification.
And these sorts of measures (using technology to restore plant life) inevitably consume much manpower, and /or fossil fuel and money in an addictive manner requiring constant attention and re-investment of such resources (because only symptoms are being addressed). Almost all of this people can avoid using animals addressing the cause, using solar energy and having no unintended consequences such as constant reinvestment of resources. There is also the matter of scale. If we are to reverse man-made desertification leading to most of today’s droughts, floods, poverty, social breakdown, violence, war and climate change we have to be realistic about scale – we simply have billions of acres to deal with and fast.
