Acknowledgements This research was carried out within the framework of the Uplands Program
(SFB 564), as funded by the Deutsche Forschungsgemeinschaft (DFG). We would like to thank
Dirk Euler for his advice on the use of statistics and Chackapong Chaiwong for his help in
understanding the soils present in the Chiang Mai basin. We should also thank Thomas Hilger
for his comments on an earlier version of this manuscript, Gary Morrison for reviewing and editing
the English content, and Peter Elstner for helping with the layout. We are also very grateful to the
villagers of Bor Krai, Huai Bong and Mae Sa Mai for their cooperation and support.
