Abstract

Climate variability in decades requires detailed research aspect basin in order to take account of climate change attested, both in making various decisions applicative and at proper adaptation to these changes. Previous research results obtained in this section indicates that territory most vulnerable to climate change is largely located within the Danube basin within the territory of the Republic of Moldova. Therefore, the purpose of the proposed research in this paper was to record some changes in the current period and which are forecasts on thermal regime and precipitation in the scale time 2016-2035.

Abstract

Although it is considered that the socio-economic impact over the last decades on surface water quality is significant, the role of changing regional climate that is manifested by the intensification of desertification process is crucial. In this context, it is important to know the current trends of change in total runoff of surface of surface waters in the context of increase of desertification degree of the regional climate attested in recent years

Abstract

Current changes of the environment represent the major threats to the sustainable development and are one of the biggest problems, with negative consequences on the national economy. The accelerated pace of these changes is shareholder and by the manifestation of extreme events, which in recent years become more intense and frequent. The drought events frequent manifestation over the Republic of Moldova territory, in the context of climate change, requires a scientific monitoring adjusted.

The dry period’s manifestation is greatly conditioned by increasing daytime temperatures (above 25°C) and the lower relative humidity (below 30%). At present, on the background of climate change, there is an increase of dry days. Over the Republic of Moldova territory, their occurrence during growth and development of crops particularly damaging role in obtaining low yields. Meanwhile, prolonged dry periods, may possibly cause fires, at the same time can determine lands’ irrigation and surface water quality.

In this context, there is a need to estimate the evaporation’s spatial and temporal variability, the number of dry days and their correlation to Dry Periods Index (Izu), the index developed at regional level.
