The Agroecological Resource Area maps were developed
to provide biophysically
units at a scale of 1:2 million w^hich can be used to study agriculture, land use

and conservation.
These Agroecological Resource Areas (ARAs) represent areas of generally similar agricultural
potential, and are based on ecoclimatic zonation, landform and soil characteristics (Figure 1).
The
ARAs have
served as a convenient planning unit upon which to develop data for use in

common linking factor, or key, between all
the
data files is the combined ARA number and province designation. ARA numbers are
unique wdthin provinces. The addition of the province code makes the key unique country-wide.
There is also a linkage, through the soil series code, to the Soil Names File and Soil Layer File,
