Abstract:Globally, the latest technological developments have driven the boundaries of environmental research to a richer and broader expansion than ever before. The rapid growth of industries has an important impact on the environment, causing several transformations that affect all stages of life on Earth. Nature’s ecosystems, air quality, climate changes by their complexity and importance on human life, have been studied through special remote sensing techniques and analysis, becoming a necessity for the new era highest research. Following their unique ecosystem, The Făgăraș Mountains, situated in The Southern Carpathians, Romania, was approached in this study by change detection techniques trying to emphasize the great impact of deforestations and of climate changes in the area. The natural reservations were devastated on a large scale, proven by numerical analysis which accurately demonstrated great transformations that may be irreversible for several species, already driven to extinction. Only by geographical information systems, from which we obtain accurate results, we could monitor these transformations and find suitable solutions in the future.


Key-Words:old-growth forest, deforestation, ecosystems, change detection, remote sensing
