International migration has become one of the major trends that shape the highly urbanizing societies of East Asia, in its larger sense including Southeast Asia. Groups are drawn towards the newly established cities in China, South Korea and in Southeast Asian countries. Environmental change, on the other hand, has also been one of the signifying elements of the global change agenda. Though, correlation between migration and environmental change is already a usual suspect for the disastrous impacts and the rising insecurity issues relevant with international migration, the cause-and-effect relationship is yet to be analyzed with a rather multidisciplinary perspective.
Hence, this study looks at multiple dimensions, for example receiving-sending country negotiations, provisions of urban services and natural disasters of this causal relationship between migration and environmental change by arguing that the initial reason for the movement of people might be any sort of environmental change but this movement leads to further securitization of environmental change with emerging environmental problems in host countries. A multidisciplinary approach by communicating international relations with integrated environmental studies is taken in order to bring out a workable solution and lessons for the newly emerging 21st century international environmental relations both in Europe and East Asia.
