Lauren Roche Posted over 2 years ago How attached are you to your deeply held beliefs? If solutions to global problems challenge your worldview, how do you react? Tom, you are not alone in this thought. I must say that my thoughts are not unbiased as a beef producer on a holistically managed property. But what I take away from Allan Savoury's talk is that there is not enough land on this earth to feed the world on plant based food. There is a lot of land in a lot of countries that is not suitable for producing crops. Whilst we could let all the land return to national parks, Allan's research shows that the land will turn to desert, even if it is locked up. Great tracks of desert, just as mountain ranges do, effect were the rain falls and in what quantities. Crops need rain at the right time to yield and they cannot be sustained in isolation of the surrounding landscape. In regards to the amount of water livestock production requires, livestock production can utilise water in different ways to cropping and the vast majority of landscapes don't receive the rainfall in the right quantities at the right time to produce a viable crop. Whereas, by holistically managing the landscape you can get that water to remain within the landscape and it can be used to water stock all year round. Also it worth remembering that he is talking about ticking two very large boxes - rehabilitating land AND feeding people.
