    ESTIMATING RECENT FOREST LOSSES IN BOSNIA AND HERZEGOVINA BY USING THE COPERNICUS AND CORINE LAND COVER DATABASES
    (Croatian Forestry Society, 2021) DRAŠKOVIĆ, Branislav; GUTALJ, Marko; STJEPANOVIĆ, Stefan; MILETIĆ, Boban
    The analysis of data from the first two decades of the 21st century shows that the area under forests in Bosnia and Herzegovina is gradually decreasing. In order to gain a detailed insight into this process, the paper will analyse the forest databases of the European satellite monitoring program Copernicus. This program, among other things, monitors the condition of forests in 39 European countries by using the High Resolution Layer (HRL). The HRL Forests database consists of 3 types of (status) products, and additional change products. The status products are available for the reference years 2012, 2015, and 2018. The status layers provide information on the Dominant Leaf Type and the Tree Cover Density at pixel level for the reference year 2018 in 10 m resolution. The Forest Type layer largely follows the Food and Agriculture Organization (FAO) forest definition. Also, the paper will use the data on forests from the CORINE Land Cover project for 2000, 2006, 2012 and 2018. The time-series includes a land change layer, highlighting changes in land cover and land use. The CLC Changes database will be analysed separately for three periods: 2000-2006, 2006-2012 and 2012-2018, due to more accurate data on forest losses. The results of the research show that forests in Bosnia and Herzegovina were reduced by 2.95%, in the period 2012-2018, where 2.55% of them were coniferous. Forests are primarily endangered by the process of conversion to transitional forest / shrub and fires.

    STRUCTURE OF AGRICULTURAL LAND LOSSES IN BOSNIA AND HERZEGOVINA
    (2021) DRAŠKOVIĆ, Branislav; BERJAN, Siniša; MILIĆ, Vesna; GOVEDARICA, Branka; RADOSAVAC, Adriana
    As the world's population grows, so does the pressure on agricultural land. Consequently, there is less and less agricultural land. Bosnia and Herzegovina is one of the countries whose population is decreasing from year to year, partly owing to negative natural increase and partly owing to the migrations of young people to developed western countries. However, despite the depopulation trend, there has been a significant decline in agricultural land in the first two decades of the twenty-first century. The reasons should be sought in various socio-economic processes that crucially affect spatial development. In order to understand the changes that are happening in the field, the paper analyzes the structure of agricultural land losses in B&H based on the database of the European project CORINE Land Cover. In relation to the five main land cover categories (artificial surfaces, agricultural areas, forests and semi-natural areas, wetlands and water bodies), the data show that in the period from 2000 to 2018 artificial areas increased spatial coverage, forests and semi-natural areas as well, while agricultural land decreased. The aim of the research is to identify the spatially largest changes of agricultural land subclasses into other types of land cover, in order to determine the causes and areas with the most intense pressure. This is essential given the fact that agricultural land is becoming an increasingly important natural resource over time. Based on the recent demographic and socio-economic trends, it is to be expected that the trend of decreasing agricultural land will continue in the future, but with a reduced intensity
