In this paper, was estimated the Climate Water Deficiency (DEF) in time and space in monthly and seasonal aspect. It was found, at the essential increase of the values DEF from the last years with a negative sign, largely determined by the increase of the evaporability and the decrease of the atmospheric precipitations. Were elaborated the cartographic models that highlight the rainfall deficit at the topoclimatic level (for example the river Ialoveni and the village of Sociteni). The results obtained will be incorporated in the Development Strategies at local level.
