As climatic risk or risk associated complex, drought is characterized mainly by the absence of rainfall, increased sun exposure, soil and air temperature, increased  evapotranspiration process, helping reduce air and soil moisture and, therefore, to reduce the pool of productive moisture in the root system of the plant, which causes wilting crops to reduce agricultural production and even to affect the total harvest, if not taken necessary measures to combat water scarcity in irrigation. In this way, the phenomena of drought and climate hazards are drought trigger environmental hazards that affect both agricultural production and the whole geographical environment, including public health. This paper aims mainly to know both the climatic features of the drought but its implications in agriculture Dobroudja. It also is intended as a warning to a careful monitoring of crops as well as for finding the best means of defense against the risk of atmospheric phenomena. In preparing this study were analyzed weather data from the period 1965-2005 the main weather stations Dobroudja (Constanta, Mangalia, Hârsova, Cernavoda, Adamclisi, Medgidia, Sulina, Chilia Corugea, Horia, Jurilovca, Gorgova, Tulcea, Mahmudia). In this study it was examined for the first time in the territory of Dobroudja, the distribution of indicators (standardized abnormal index, standardized precipitation index), highlighting areas within the risk and the action may be taken to prevent being of real help for farmers Dobroudja.
