Answer 2

Answer:

The aim of the present study was to determine the factors that effected the beginning of the Anthropogenic Era (human age) in Turkey and formation of biomes. Destruction of vegetation, soil erosion and land degradation are the most important factors in the formation of anthropogenic biomes in Turkey. For this reason, first of all, a literature review about land degradation, which has been going on for past 300 years in Turkey, and about its causes was made. Changes that have occurred over the last 70 years were studied with the help of aerial photos and satellite images. In addition, studies we have conducted in the last 35 years have contributed substantially to the determination of the extent of the destruction of vegetation and land degradation in Turkey. As a result of research based on literature reviews and fieldwork, the impact of humans on the natural habitat were identified, and the current situation was studied. The findings about the current situation that emerged due to human impact were then transferred to an electronic environment, and a map of anthropogenic biomes was produced with the help of ArcGIS Desktop software. Based on the results obtained, one can say that the natural habitat has considerably changed over the last 200 years; vegetation has been damaged, and land degradation has become faster because of human activities. These results indicate that 97% of natural biomes have become anthropogenic biomes, and this change has become more obvious during 20h century in Turkey. The results also show that the change has been more influential after 1950.
