a In order to simplify the data, the hilly lowlands have been incorporated in the lowland data
fields since they first started cultivation (Table 3.6). The analysis of these land use
changes, which spanned a time period of 30 years, reveals that in only 35 percent
of all fields some adaptation had taken place. These changes most often entailed the
integration of trees into a field that did not contain trees before. The conversion of
a field with trees into a field without trees has been relatively rare. Trees have been
introduced rather than removed from the farming landscape. Table 3.6 shows
remarkable dissimilarities between upland and lowland areas. Tree introduction is
more pronounced in upland areas, while in the flat and often most fertile lowlands
the emphasis clearly lays on seasonal cropping.
