The drought is a natural phenomenon, but the human presence is causing huge socio-economic losses in the state of Rio Grande do Sul, mainly in the agricultural sector. The main objective of this work is the spatialization of the occurrence of drought in the Rio Grande do Sul, in the period 1981-2011, using the Kriging method. As from the Kriging three maps divided for decades and one map of the summation of the 31 years considered were generated, besides a map drawn up using the municipal division. It was found that the higher occurrence of drought is concentrated in the southwestern portion of the state, visible both in the spatialization of the municipal division as the zoning performed through Kriging. Considering the spatialization obtained through of the Kriging for the whole period it is observed the reduction of the areas of high occurrence of drought in west of the state and of the areas of low occurrence in the eastern portion of the state. With this, we expect to contribute in planning and investment, aiming to reducing economic losses, especially in the agricultural sector in the state.
