My story has changed a bit in regards to organic agriculture as a global solution. I am sharing my ideas with people every day. I am thinking of it as the good news. My, now zen-buddhist-philosopher father was a preacher when I was young and I can remember him talking about giving people 'the good news' - maybe it is in the blood.
Anyway, sitting at the IFAOM Booth at the COP15 (H-017F) I have been approached by many people who want to hear about yields and argue about the merits of a high input conventional system for the necessary yield increase for a growing world population.
My response, thus far, has been to report the fact that the world is already producing more than enough food to feed everyone - the problem is giving access to that food to the people who need it. Another argument has been to point out that the yield potentials of high input systems is based on the additions of resource inefficient and biologically hazardous chemicals. The pesticides and herbicides remove the potential for the farmer to harvest nutritionally important non-crop food sources. This is a big problem in a world where 1 in 3 people is a farmer and most of these farmers are marginalized people on degraded land and a tradition of gathering food in nature as well as from cropping systems.
After a short chat with Australian Water Lilly farmer and IFOAM World Board member Andre Leu I have learned that the yield potential in organic systems in no lower than in conventional. Having a quick cruise around the web and a read of his 2005 work on the subject I can see that he has strong scientific support for his arguments.
