Sustainable Agriculture
June 5, 1997
Dear Colleagues,
Although the urgent need for a sustainable agriculture is well documented,
criteria (and indicators) for sustainability have not been well
established.
Since sustainability is defined a posteriori, THE QUESTION IS how can we
know that an agricultural system (for instance no-tillage agriculture with
numerous positive/negative points) is sustainable?
I would appreciate it very much if you could participate in this discussion!
Many thanks in advance,
Cyrus
