(fwd) Paul Zinke, Professor Emeritus, Forestry and Resource Management, 231 Mulford Hall, University of California, Berkeley, CA 94720 spent years studying slash and burn agriculture. My recollection of his work that I heard in a presentation many years ago, is that slash and burn is an excellent system if the rotation is long enough... low populations. He has excellent quantitative data on soil erosion, methodology, etc. At 08:21 AM 12/25/96 -0800, you wrote: > > >---------- Forwarded message ---------- >Date: Wed, 25 Dec 1996 05:40:40 -1000 >From: Jay Hanson >To: sustag@beta.tricity.wsu.edu >Subject: Does anyone know of sustainable ag from antiquity? > >Are there any well-documentated, instinces of sustainable >agriculture from antiquity? > >If so, can someone give me a synopsis and references? > >Jay > > >[Does anyone have the volume/date for the Agronomy Journal issue with >a symposium on this a few years back?
