The diversification of beech genotypes on the territory of the Republic of Moldova could be a so-lution to avoid the risks caused by climate change. The objective of this research was to determine the viability of beech seeds collected from four areas of the Ivano-Frankivsk region (Ukraine) and their modi-fication under the influence of various abiotic factors. The analyzed seeds possessed high viability (77.89 – 96.63%), which under the influence of supra optimal temperature +40°C decreased 1.3-1.4 times de-pending on the applied dose. Seeds exposed to heat treatment used reserve substances for radicle growth 1.4 – 1.6 times more than the control.

Abstract The viticulture, a traditional branch of the national economy, is closely related to climatic conditions because the Republic of Moldova territory represents the northern border of its territorial location. Therefore the knowledge of regional particularities of grapevine productivity formation in dependence of current agro-climatic conditions is of particular interest. Along with accelerated climate change in last decades over the Republic of Moldova territory, we find that are essential changes concerning agro-meteorological conditions, at the same time comprehensive researches that would reflect the actual impact of climate change on grapevine are limited. There are known researches, but in the context of changes that occur at regional level it is necessary to supplement permanently the database in order to elaborate an appropriate estimation of current climate conditions. The above reported facts show the importance of parameters influencing the grapevine productivity time and space study in Republic of Moldova.

Abstract The accelerating pace of climate change is associated to weather-climate related risks manifestations, which in recent years are becoming more intensive and more frequent. Unfortunately, we find that far at regional level there are no a basic scientific information which could highlight their specific spatio-temporal manifestation. In this context, criteria for several weather-related risks identification were quantified, the main ones being material damages, the number of casualties and victims and not the least - and the period they occur. The identified weather and climate related risks may be subject to a complex spatiotemporal analysis, having as a research tool - Geographic Information Systems.

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 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.

The parasitic angiosperm Orobanche cumana is present in the main sunflower-producing countries around the world. In recent years, more aggressive races of broomrape have evolved and the parasite has rapidly spread to new areas. A similar trend has been observed in the Republic of Moldova. At the beginning of 1950s, broomrape was detected in Moldova, especially in the southern areas. Currently, all the known races of Orobanche are present in the country and the parasite has expanded considerably on new areas in the center and north. Based on these results and the data reported by other authors, related to influence of climate change on the phytosanitary situation, we studied the interdependence between the climate and the distribution of Orobanche cumana Wallr. over different parts of the Republic of Moldova. Prevalence of broomrape infection mainly in the southern and central part of the Republic of Moldova and its sporadic presence in the northern part can be influenced, not only by short rotations, type of sunflower hybrids grown and soil parameters, but also by the weather conditions such as higher temperatures and lower humidity in the south and center. Based on multiannual data and trends observed in recent years, characterized by an increase in temperature and decrease of relative humidity, we conclude that climate change will create favorable conditions for infecting sunflower plants in all the areas where sunflowers are grown, including the expansion of broomrape to the north of Moldova.

Abstract In the Republic of Moldova, regardless the limited area, regional climate change represents one of the major threats for sustainable development and is one of the biggest environmental problems, with negative consequences for the national economy. Displacement function analysis of the climate rules distribution which is characterizing mean annual temperature at different times in the Republic of Moldova shows that the last decade of the twentieth century (1989-1999) was the warmest decade of the century. At the same time, the first decade (2000-2012) of XXI century is the warmest decade of instrumental observations series (1887-2013). Measurement of the extreme values modification in the Moldova’s climate evolution indicates that absolute maximum of temperatures and deficit (excess) of precipitation have a regular manifestation on the last period (2000-2012).
