permaculture

[Dieter Brand <diebrand@yahoo.com>]

Hi, 

I remember reading that Egyptian farming a few thousand years ago produced a 
higher yield per acre than industrial farming in the US today.

My files and data resources are in a complete mess and I can’t find that 
reference again.  I now need it because I’m involved in a general discussion 
forum about the need for sustainable farming.  These people are completely 
ignorant about farming and firmly believe that industrial farming is the most 
efficient farming method in existence.  They won’t believe anything I say 
unless I come up with some good references.

Can somebody help me out with some easy to understand references or 
scientific studies showing example of traditional farming that did achieve a 
higher yield than industrial farming.

Thanks, 
Dieter
