Note générale :	Agroclimatological parameters such as the annual rainfall, the start and end of the rains, the length of the rainy season and evaporation, are closely related to latitudinal position. These relationships are quantitative expessed en terms of regression equations, which are usuel to examine the causes and asess the severity of the 1972 drought in the drier zones of northern Nigeria and neighbouring countries of Niger and chad. A northern limit of arable farming based on the minimum requirements for the cultivation of millit is established along lat. 14.7°N.
