    East Sarajevo (Bosnia and Herzegovina) twenty years later –changes in land use
    (University of Novi Sad, 2016) Drašković, Branislav; Drešković, Nusret; Mirić, Ranko
    The city of East Sarajevo is a newborn city, formed twenty years ago, after the war in Bosnia and Herzegovina, in the area of the former southern and eastern Sarajevo municipalities. Changes that occurred in this area were not only administrative-political.Thepopulation moved from one area to another place, and changed in number and structure, which has resulted in significant changes in land use and land cover types. The aim of the paper is to analyze the types of land cover in the area of East Sarajevo using methods based on remote sensing, in order to find out the degree of these spatial changes in the period from 2000-2012, and also to define spatial development trends. Within the European project of remote research of land cover types and forms of land use, namedCORINE Land Cover (CLC),spacious facilities were identified from middle and large scale spatial resolution, with 5 first-level classes, 15 subclasses, and 44 subclasses of the third level of cover. Analyzing the area of East Sarajevo there are identified 3 of the first-class level, 10 second-class, and 16 third-class level types. Geodataare related to three observation periods: 2000, 2006, and 2012, comparing the situation at the beginning of the period with the situation after 12 years.

    HORIZONTAL AND VERTICAL SPATIAL DISTRIBUTION AND LOSS OF GRASSLAND IN BOSNIA AND HERZEGOVINA
    (Geographical Institute "Jovan Cvijić" of the Serbian Academy of Sciences and Arts (SASA), 2022) Drašković, Branislav; Petronić, Slađana; Gutalj, Marko; Marić, Nataša
    Two databases related to grassland in Bosnia and Herzegovina (B&H) have been used in this research—the Copernicus Grassland (GRA) and CORINE Land Cover (CLC). The data have been processed by using GIS tools, and the spatial distribution of grass vegetation in relation to three biogeographical and four elevation zones has been determined. By using the Copernicus Water and Wetness (WaW) database, an insight into the coverage of grass vegetation in wetlands has been obtained. In addition, the analysis of changes in databases determined the total amount and location of the largest grassland losses. Based on GRA database, B&H is one of the richest countries, with 22.4% of its territory covered by grassland. According to the CLC database, pastures occupy 6.3% and natural grasslands 5.6% of the territory of B&H. However, grassland is exposed to various anthropogenic and natural processes that affect its distribution, quality, functions, etc. The CLC database has been processed by extracting the grasslands (pastures and natural grasslands) and calculating their spatial coverage and changes which happened during the three six-year periods from 2000 to 2018. The trend of decreasing pasture areas and increasing natural grasslands has been noticed. The pastures are most endangered by the processes of conversion to other types of agricultural land, while natural grassland increased spatial coverage during the period 2012–2018 mostly due to the revitalization and grazing of burned areas in the region of Herzegovina. Grasslands have been particularly targeted for afforestation and cropland conversion at present

    LAND COVER TYPES AND CHANGES IN LAND USE IN REPUBLIC OF SRPSKA (BOSNIA AND HERZEGOVINA) OVER THE PERIOD 2000–2018
    (Geographical Institute "Jovan Cvijić" of the Serbian Academy of Sciences and Arts (SASA), 2020) Drašković, Branislav; Ponosov, Aleksandr; Zhernakova, Natalija; Gutalj, Marko; Miletić, Boban
    Republic of Srpska (RS) covers an area of 24,666 km2 or about 48.5% of Bosnia and Herzegovina’s territory. Spatial and environmental changes accelerated due to dynamic historical period upon the RS formation and the following development period. The extent of these changes can be determined by comparing satellite images obtained from different acquisition periods. By processing images, with the support of geographic information systems, it is possible to create a database that aims to analyze spatial processes in a specific area in order to determine quantitative and qualitative parameters. In this way, the trends of spatial development (e.g. excessive logging, land cover damage, water pollution, etc.) and potentially vulnerable components of the environment can be monitored. The data for Bosnia and Herzegovina were collected from CORINE Land Cover (CLC) database for 39 European countries. The CLC is a project launched by the European Environment Agency (EEA) more than thirty years ago with the aim of collecting, coordinating and ensuring the consistency of information on natural resources and the environment. The goal of the paper is to identify land cover types and determine environment changes in the territory of Republic of Srpska over the period 2000– 2018 as a consequence of the land use conversion.

    Urban Expansion of the Largest Cities in Bosnia and Herzegovina over the Period 2000-2018
    (2021) Drašković, Branislav
    The paper analyses the databases Urban Atlas (UA), Imperviousness, and CORINE Land Cover (CLC) for the largest cities in Bosnia and Herzegovina (B&H). The UA database contains information for five functional urban zones with more than 100,000 inhabitants: Sarajevo, Banja Luka, Tuzla, Mostar, and Zenica. The Imperviousness database is related to the subclasses of the urban atlas because the impermeability percentage has been used for a more detailed classification within the discontinuous urban area. The CLC database provides insight into the intensity of expansion of these cities during three six-year periods: 2000-2006, 2006-2012, and 2012-2018. The research has been used to analyse the expansion of urban zones, the structure, and form of cities, and the impact of urban expansion on the surrounding area. The results of the research show that, despite the negative demographic trends, there is a trend of urban expansion in B&H, mainly overthe agricultural land. According to the CLC database in the period 2000-2018, artificial areas increased in spatial coverage from 1.35% to 1.7%, and urban fabric from 0.99% to 1.27%. The Imperviousness database shows that in 2018sealed areas covered 1.59% and built-up areas 0.8% of the territory of B&H. The 2013 census showed that the number of inhabitants in all five functional urban areas decreased compared to 1991, but despite that fact, the expansion of urban zones continues with a weaker or stronger intensity.So far, there has been no research on urban development based on the high-resolution layers UA and Imperviousness database in B&H, so that such research is the most significant contribution of this article
