THE STRUCTURE ANALYSIS OF POPULATION BY AGE GROUPS IN THE RURAL AREAS OF BUCOVINA

The structure analysis of population by age groups in the rural area of Bucovina desires to create a recent image of the rural population by age groups in the region of Bucovina , provided that after the year 2000 have occurred socio – economic changes with repercussions on the demographic component. The structure analysis by age group will be based on the share of population indicators on the major age groups, the share of population by age and quinquennial gender illustrated by age pyramid, the index of demographic aging and age-dependency ratio. This study is definitely needed in forecasting future regional development objectives and measures

Quantitative analysis of Soil loss in the Plateau administrative territorial units of Suceava county

Beginning with the statement that the economic activities of the main sector occupy a majority share in Suceava Plateau, this study aims to highlight the negative impact that the use of the land has on soil. The determination of soil loss from the said area will be accomplished through a GIS analysis using the USLE model (Universal Soil Loss Equation), where, in addition to the land utilization will be taken into consideration a number of other factors regarding the climatic, soil and topographic particularities.  The result of this type of modeling permits an inventory of the soil loss values and the identification of areas where the admitted quality of soil loss is exceeded, therefore, being lost the main nutrient elements of the soil, decreasing fertility. The utility of the USLE model application is found in determining the crops alternation structures or in determining the soil protection measures. Moreover USLE model is an effective tool in defining a territory’s dysfunctions connected to the soil’s degradation, screening an eloquent image of the existing situation regarding the environmental quality in developing the land setup plan

LANDSLIDE SUSCEPTIBILITY IN THE RURAL AREA OF BUCOVINA

The territorial support of the Bucovina region is characterized by its complexity, this characteristic deriving primarily from the fact that it meets in its boundaries different properties, the western part being a mountainous region and the eastern one of plateau. Sketching an actual image of the existing dysfunctions of the region from a natural perspective requires an analysis of the susceptibility of landslides, this being one of the most common problems when it comes to the quality of the natural support of a geographic complex. The predisposed areas to this type of hazard will be outlined into a cartographic support according the semi-quantitative method governed in Romania by G.D. no 447/2003 which establish the elaboration and the content of natural hazards at landslides. In order to achieve this objective, it has been used G.I.S. technique both for the construction of vector and raster necessary data bases and for statistical analysis of the final results. Last but not least through the mentioned technique it can be identify the risk caused in the territory by landslides. One of the benefits of this study is the forecasting of regional development projects in rural areas from Bucovina

An Innovative Approach to Assess the Ecotoxicological Risks of Soil Exposed to Solid Waste

The adoption of sustainable waste management strategies is a challenge faced by most European countries, mainly due to the need to generate less waste and replace landfills with new methods of waste treatment, associated with increases in the separate collection of waste and recycling rates. This paper highlights the significance of environmental legislation regarding waste removal to protect ecosystems. The aim was to predict ecological responses to heavy metals in soil exposed to hazardous waste and to identify environmental hazards in landfills, small illegal waste dumps, and litter, in addition to identifying if heavy metal accumulation in the investigated soil samples showed a single or cumulative risk. This is an innovative method to predict the ecological risk generated by hazardous waste landfills. The assessment of ecological risks was based on the evaluation of a heavy metal soil contamination factor, pollution index of soil loadings, a geo-accumulation index for heavy metals, and potential ecological risk. The current study is also the first to attempt to identify the dimension of risk based on the type of waste deposit (landfill, small illegal waste dump, and litter) and to identify potential patterns. The geological index corresponding to cadmium Igeo(Cd) showed heavy contamination in the soil samples from the landfill and moderate contamination for those from the illegal waste dumps. These findings indicate that soil contamination is influenced by contamination time, anthropogenic processes, and a history of industrial activity, and not only by waste composition and storage. The present study shows that cadmium might be considered a latent fingerprint for waste disposal, which is correlated to the industrialization level and rehabilitation procedures
