METHODOLOGICAL APPROACHES IN ASSESSING THE ECONOMIC PRESSURE ON FOREST RESOURCES. CASE STUDY: APUSENI MOUNTAINS

Abstract

Assessing the economic pressure on the forest fund is one of the greatest challenges for the scientific world due to the dynamics of the phenomenon and the difficulties in obtaining relevant data and in an optimal time. For this study, we wanted to analyze, compare and aggregate two sets of post-processed images from two different sources, such as CORINE Land Cover (with complementary datasets) and Global Forest Change, to get a more accurate and relevant result. For this we processed the post-processed images from both sources, then merged the information of the two sets of data by keeping the temporary resolution from Global Forest Change and taking quality information like the type of vegetation from CORINE Land Cover. The data set obtained was corrected and then processed. The results obtained have highlighted the limitations of each data source, temporal limitation and lack of information on forest type in the case of Global Forest Change and the methodological differences in data collection and lower temporal frequency within the CORINE Land Cover. Thus, in order to obtain more precise results on the dynamics of forestry in a region within the European Union using free / available online data sources, it is necessary to merge such data sets.
