I would like to extend my expose to cover also dry pulses and groundnuts which make up, together with cereals, the greater part of grains stored at farm and village level.

To begin with, we should make a distinction between, on the one hand, countries with a rather good road network and more or less workable grain marketing institutions, where farm storage has much decreased and in some cases nearly vanished, and on the other hand, countries where the isolation of producers and absence of good marketing institutions have helped to conserve the traditional storage methods on the farm, and occasionally, in the villages. As examples of the first type of countries, I would indicate Kenya and Zambia and of the second type, Chad and a large part of the Sudan.
