<p>In hydrogeological and pedoclimatic conditions, specific to the Danube River, there is a danger of secondary salinization of soil excluded from the floods. The drought, with an increasing frequency, affects agricultural production in areas where the largest irrigation systems are found. These systems were built during 1960-1990, but they are dysfunctional and unused for 20 years.</p><p>The purpose of this study is to insure a model using GIS technologies, in order to reduce the negative effects of the drought and to propose redevelopment of irrigation. Such model is presented in a form of five thematic maps where the main morphometric parameters (hypsometry, slope, slope orientation), in quantitative terms, the types of soils and land use were analyzed for the entire surface of the villages Gostinu-Greaca-Arges, located in the Danube Floodplain. The GIS model provides important information for the investigated area and it is a useful tool for risk assessment and early-warning.</p><p>This study is based on observations from the maps interpretation of the studied area, but also from reports and studies published over the years.</p><p> </p><p>Keywords: The Danube River, drought, soil, irrigation.</p>

The knowledge of medicinal plants and honey plants has been one of the most important concerns of people since the beginning of their existence. The use of plants for therapeutic purposes has been transmitted over the millennia from generation to generation, and today we are witnessing a reconsideration of the traditional medicine, in the sense that research show that herbal medicines are products more biologically accessible to human metabolism than synthetic drugs which sometimes produce side effects. The lack of scientific knowledge to explain the therapeutic qualities of these plants has long made their healing power a "mystery." Due to the progress of science, the extraction of medicinal principles from the herbs and the synthesis of new drugs have emerged. Around the world there is a wide variety of Salvia spp. spontaneously growing plants; many of them have valuable medicinal properties while others are used for decorative purposes. The aim of the paper is to show how this ancient plant has conquered the world with its qualities.
