Our paper focuses on studying the development and implementation of a comprehensive environmental safety assessment and mitigation strategy for countries of origin and destination of environmental migration. Environmental migration represents one of the key threats to the security of regions and countries and is linked to their sustainable development (or lack thereof). Moreover, it is also connected to many important social, economic as well as demographic outcomes. Global warming caused by human activities is already having a major impact on the planet and is likely to render parts of the world uninhabitable, leading to migration, displacement, and planned resettlement. The goal of the paper is also to assess the impact of future migration due to the global warming and climate change. The results of the paper demonstrate that climate impacts can trigger migration and change population distribution within the next few decades. It is also clear that migration caused by the environmental factors (such as droughts, floods, higher temperature sand more extreme weather events) would inevitably lead to the geopolitical changes with long-range impacts and effects.
