Global warming, environmental security and its geo-economic dimensions case study: Caspian Sea level changes on the balance of transit channels
2020
Global warming and climate change are considered as important environmental problems. Environmental security is more pronounced with regard to the Caspian Sea. Due to the geopolitical and geo-economic dimensions on the one hand, and its unique characteristics on the other, this large lake is considerably fragile against environmental challenges. In fact, the innate isolation of the Caspian Sea makes its conditions with regard to global warming unique. Using a descriptive-analytical method and library and valid article references, this study seeks to answer the question: “what are the effects of global warming on environmental security and what challenges does it pose to the Caspian Sea from the geo-economic point of view?” And Also maps and charts related to the research topic were collected and plotted in the GIS. In the next step, using a descriptive-analytical method based on geopolitical perspectives, especially environmental geopolitical studies and internet searches, we analyze the spatial effects of this universal phenomenon in the context of environmental geopolitical systems. The findings indicate that global warming will pose a large spectrum of challenges and problems to the Caspian Sea from the destruction of its ecosystems to the complete transformation of its nature. This research has studied global warming and its effects on the sea level changes of the Caspian Sea and particularly the level of water in the transit channels of the Caspian Sea from the geo-economic point of view. The results show that fluctuations in the water level of the Caspian Sea, in addition to environmental challenges, narrow the balance of its transit channels and threaten the geo-economics and environmental security of the Caspian Sea.
