In this paper, within the framework of morphostructural features, relationship between relief and geological structure in the river basin of Solina (north-eastern Bosnia and Herzegovina) is analyzed. Main goal of this study is to investigate causal relationship between complex geological characteristics of the terrain and genesis, morphological evolution and differentiation of three relief units in the river basin of Solina. Relief of river basin of Solina is predominantly non-conformal, tectonically predisposed; its structure is dominated by Cretaceous - Paleogene clastites. In this paper are applied modern geomorphological-geological methods, field work, analysis of topographic and geological maps, as well as satellite images of the studied area. Presentation of data has been realized in the Geographic Information System, and the geospatial data were geo-visualized on two thematic maps.

The war during the period 1992-1995 has caused massive forced migrations of the population in Bosnia and Herzegovina and in this period about 1.2 million people fled beyond the borders of Bosnia and Herzegovina while about 1 million were displaced inside the country. After the Dayton Peace Agreement, there started the process of return of refugees and displaced persons in Bosnia and Herzegovina. However, even after more than 20 years since the signing of the Agreement a significant number of refugees and displaced persons has not returned to their pre-war places of residence. This paper explores the number and the change in the status of the internally displaced Bosniaks of Srebrenica Municipality in the period 2005-2015, those who were residing in Tuzla Canton of the Federation of Bosnia and Herzegovina. According to the Federal Ministry of Refugees and Displaced Persons in Tuzla Canton, in 2005, the status of internally displaced persons had 2016 households with a total of 5549 members, and by 2015 this status has kept 1099 households with a total of 2867 members. The aim of this paper is to point out to some more significant factors that led to a reduction in the number of Bosniaks from the area of Srebrenica municipality who had the status of internally displaced persons in Tuzla Canton.

In the second half of the 20th century, demographic changes of the Tesanj municipality developed in accordance with the complex socioeconomic circumstances in this area. In the period from 1953 to 1991 the population of Tesanj municipality increased by the average annual population growth rate of 1.5%. The biggest impact on demographic trends had the positive and relatively high rates of natural increase. The natural population change of Tesanj municipality in this period was the result of the effect of biological, socioeconomic, psychological and other factors. In this period fertility significantly influenced the rates of natural increase of municipal population. The gradual decline process of the fertility rates, which has started in the 1960s and still lasts, reflected on the natural population change and population growth rates of Tesanj population. Additional decrease of the fertility and birth rates, as well as moderate increase of mortality rate was observed. This occurred due to the decrease of the total population, as well as the adverse socioeconomic circumstances after 1995, which resulted in low natural growth rates.
