Effective management for agricultural development depends strongly on
the regions' infrastructure and local community's culture and means We
stern world agriculture management, cannot simply be copied to the Afr
ican semitropic conditions. Developing effective management systems fo
r any specific local condition, demands a quantative in-depth understa
nding of the particular soil and climate restrictions in which crust f
ormation, surface seal and very high rain intensities are the dominant
factors. A computer-based approach to this problem has been proposed.
The approach adopted in Israel will be described in this paper, along
with an illustration of applications on various scales of time and sp
ace. Study of a Cameroon rain storm reveals a promising method which i
s based on the small basin concept, absorbing all the rainfall in situ
. The system is the Areal Basin, locally called, diguette. The main id
ea here is to divide the area into big basins, each of them practicall
y a small field. They are to be cultivated by the farmer, whatever mea
ns are available to him, that is, manual labor or animal traction.
