agriculture in South East Asia is that upland rice is cultivated as
the main crop. However, it is possible to categorize swidden
agriculture in the region into several types, according to the
different combinations of swidden crops.
1. The upland rice dominant type (one year cultivation)
In tropical and subtropical monsoon forest regions in continental
South East Asia (including the Indo-Chinese Peninsula
and southern Yunan, in China) upland rice is widely cultivated
as a main swidden crop for a year, and then the land is fallowed
for several years. Typical examples are the swidden systems of
the Lamet and the Hill Lua'. The tradition of mixed cropping
is demonstrated in the swidden fields of this type, and small
volumes of various types of millet and beans are cultivated as
well as upland rice. Many oral traditions are preserved in the
region. From these it is suggested that in former times millets
were grown much more than at present. From this it is possible
to assume that this kind of the swidden cultivation had been
a "millet dominant" type. The system of the Chins, of northwestern
Burma, is a typical example of the millet-dominant
cultivation type, as millets and beans are still major crops.
Upland rice is superior in quality, not only as a crop but
also as food. Therefore it was probably selected from among
many kinds of millet and increased drastically in importance.
As a result, a later transition in continental South East Asia from},
