All marketing channels are highly influenced by the availability
of roads and transport facilities. In the history of the country's
development, the opening of a new road always induced an increase
of marketed production. When there is no access to a road,
transport is limited to headloads which is an extremely expensive
type of transportation. Profits, after transportation costs
have been deducted, shrink to zero after a few miles so that
the existence of a road is crucial for a traditional farmer
to be able to engage in marketed production. As all peasants
need cash for taxes, clothing, etc., the existence of roads
determine, to a considerable degree, the settlement pattern.
The opening of a road causes an increase in the population
density of the surrounding area.
Because of the limited number of roads, the producer does
not have the possibility of choosing a market place, as there
is only one in the vicinity. This, as well as the lack of
price information, causes a low degree of market mobility.
Markets for agricultural inputs play a minor role for the
time being. Concessions and commercial farmers have their
