The topic presented by Martin Kropff at the summer 1994 course at
Gainesville should not be cited relative to our course, because it will
not be published in that manner.  I suggest that you contact Martin
Kropff directly.  The topic was presented at a "Rice and Climate Change"
Symposium at IRRI in March 1994 and there is a proceedings of some type
resulting from that symposium.  Try "M.J. [log in to unmask]"  Good luck.
