For Roche, the term drought has two meanings: " ... a climatologic one: period or year during which precipitation is considerably below the mean" and " '" a hydrological one: period or year during which the runoff is considerably below the mean:' He notes that "drought manifests itself over time (dry period) whereas aridity is a spatial phenomenon (an arid region):' 28 1 .

The degree of reflectivity of the soil, and its variation may be measured with the aid of remote sensing. There is a general consent on the relationship between erosion of soils, their degradation and an increase in the albedo. Charney (1975) advanced a theory of the aggravation of drought in the Sahel from an increase in the albedo of the soil surface as a result of degradation caused by rural activities which lead to a larger portion of the incident radiation becoming compensated by a greater subsidence of the air in contrast to the convective mechanisms leading to precipitation.
