Impactul activităților umane asupra stării peisajelor geografice din bazinul hidografic Cogâlnic în anii 2004-2014

The high degree of land use in the Republic of Moldova as a whole, and the Cogâlnic river basin in particular, imposes the need to assess the quality of the environment and the characteristics of the anthropogenic pressure on the landscapes in temporal and spatial dynamics and to identifying an adequate of measure system for the purpose to maintain/restore the optimal structure and functioning of landscape systems. Based from the Land Cadastre on data, statistical data of population censuses, bibliographic and cartographic sources, a system, was appraised a system of indicators(of naturalness, of artificialization of landscapes, environmental changes) and quantified human pressure on the environment through agriculture and anthropogenic pressure on forest landscapes from the Cogâlnic catchment area. The values of the indices and the human pressure on the landscapes were processed using GIS techniques and elaborated cartographic models.

Analiza modului de utilizare a terenurilor în Regiunea de Dezvoltare Nord a Republicii Moldova

Analiza factorilor determinanți ai evoluției speranței de viață la naștere în România (1990-2018)

Analysis of the determinants of life expectancy at birth evolution in Romania (1990-2018).

From the stagnation that characterized the last part of the communist period, in the first phase, the deterioration of living conditions, transposed in the decline of this indicator, especially in the rural environment and for the male gender. Starting with 2000, however, there is a continuous recovery, an expression of the improvement of the standard of living but also of some behavioral changes. In this context we can legitimately ask ourselves what were the determining factors of this evolution and to what extent each one intervened. The identification in the specialized literature of a number of 8 factors and the creation of a related database allowed, through linear regression and multiple regression, to establish a possible answer. The evolution of life expectancy at birth in territorial profile and its correlation with the distribution of the main causes of death were analyzed. It was observed the persistence of regional disparities but also the change of the weight of some explanatory factors. These developments can be accounted for by the unequal adaptation to the new context imposed by the transition to the market economy, especially benefiting the cities with a strong medical infrastructure.
