Climate change and the impacts of anthropogenic activity on climate in Europe is documented in many scientific publications but the investigations about climate impact and particularly urban climate are relatively few for Bulgaria. The present paper investigates the variability of seasonal and annual air temperature in Sofia city and surrounding areas (towns Bankya and Bozhurishte) for the period 1961-2015 based on the linear regression method. In order to investigate the urban heat island (UHI) intensity, the air temperature difference between the city and its surroundings is calculated. The study shows increase of air temperature difference between the city and suburban territories during the recent years. The linkages between the observed variability of air temperature difference and atmospheric circulation and urbanization are investigated.
The purpose of the present study is to present the demographic characteristics of the urban settlements situated in the mountainous disadvantaged area of the South-West Development Region, Oltenia. Following our analysis, several aspects have been asserted: the numerical evolution of the population and identifying categories of urban settlements as resulting from the demographic dynamics, the natural and territorial movement of the population, the demographic behaviour expressed by demographic potential and marriage stability, the indicators pointing out gender, age, ethnical and confessional structure of the population.
The main goal of the work is to analyze the dynamics of migration in the Resita city and its area of influence. The need for this study is relevant in the context of the current development of the case study area, marked by economic changes that have brought about effects in the demographic, social and cultural fields as well. The case study selected is a geographic area with a relatively large spatial extension, where the historical and political factors visibly marked socio-cultural aspects of human habitation. Resita’s industrial past left marks on the current economic landscape because of the fact that, although the industrial nature has remained dominant, nevertheless, influenced by economic reorganization, it has required an apparent downsizing, from the point of view of both production and workforce. The economic and social evolution of the Resita city influences also the rural space located in its area of influence. This situation was reflected in a decline of the migration of workforce drawn by Resita from the surrounding area.
The purpose of the present study is to correlate the ethnical structure of the population with toponyms designating human settlements. For that purpose, we have analysed the ethnical distribution of the population declaring its ethnical appurtenance at the national census in 2011, we have identified the names of human settlements that hint at ethnical groups’ presence and then correlated the names of those settlements with their national demographic structure.
From the point of view of the connection between the present percent of ethnical groups at the level of communes and the territorial distribution of oiconyms having ethnical connotation, we have identified a high correlation in the case of Romanians, only in part for Hungarians and no connection at all regarding Greeks, Polish, Macedonian, Jew or Turkish people; this result could only be related to a high mobility of the population, other that the majority one, added to substantial changes in the national structure of the population in the course of time.
Abstract: The analysed geographic region knew an uninterrupted autochthon dwelling, starting with the Neolithic era and until nowadays. The numeric evolution of the rural population from this region, beginning with the 19th century, was similar to that from the national level. After a continuous ascendant evolution until 1956, when it was reached the maximum value (155,992 dwellers), the numeric dynamic of the population followed a descendant curve. The analysis of the demographic indicators (1977-2006) evidences the next situation: decreasing birth rate, increasing mortality rate and migration, the installation of a slow but continuous process of demographic aging, higher share of the feminine gender population, the growing demographic and economic dependence ratio, the lowering of the population’s activity rate.
Abstract: Le but de cet article est de présenter certains éléments de l’habitat insalubre au Maroc à la fin du XX-ème siècle. Pour cerner l’habitat insalubre au Maroc dans toute sa complexité, une approche approffondie de sa problématique, de son contenu et des aspects qu’il revêt dans les différents tissus urbains s’avère indispensable; j’analyse ensuite les mécanismes de formation et de développement de ce type d’habitat; enfin, j’évalue les principales formes d’intervention publique (collectivités locales et opérateurs publics spécialisés) dans ce domaine.
