measurement and the recognition by them that this was useful information. Because
of this, many of the farmers who had not been able to provide estimates on yields
of various indicator crops were able to do so in the subsequent round of measure-
ments, while those who had been unwilling to provide income-related information
were willing to do so. With further measurements, it would be possible to assess the
impact of these on the accuracy of the measurements. In addition, other methods of
collecting data on the indicators should be explored to minimize the cost and the
interviewer biases inherent in the methods used in this study.
The possibility of an overall reduction in the technical biophysical efficiency
of most LUUs between the first and the second measurements is indicated by the
