Hi Dieter,
Check out http://www.fao.org/docrep/005/y4137e/y4137e00.htm
Organic agriculture, environment and food security (FAO 2002).

And more recently:
Right to Food: “Agroecology outperforms large-scale industrial farming for 
global food security,” says UN expert
http://www.ohchr.org/en/NewsEvents/Pages/DisplayNews.aspx?NewsID=10178

That should give you some pointers. You could also google "Miguel Altieri" 
with
appropriate keywords. He is one of the foremost academics in agroecology and 
has
looked at these issues as far as I remember from doing a course with him 
several
years ago.


Best,
Ute
