Chapter 4: Climate change induced displacement and international law

Mariya Gromilova and Nicola Jägers


Already in 1990, the Intergovernmental Panel on Climate Change (IPCC) predicted that one of the greatest impacts of climate change will be on human migration. Although it is complicated to estimate the precise number of those likely to be displaced as a result of global warming, according to the UN this number ranges between 50 million and 350 million by 2050. he current situations in Bangladesh and in a number of small island States in the Pacific region are among the most striking examples of what we can expect from climate change in the near future. Bangladesh, due to its geographical and spatial location is already among the most environ- mentally vulnerable regions, with around 20 percent of the land one meter or less above the sea-level. According to the 2007 UN Fourth Assessment Report of the IPCC, a one meter rise of sea-level will cost Bangladesh up to 17 percent of its land, and will displace at least 35 million people by 2050. The risk for small islands is even more dramatic, as according to the prognoses, such islands as Tuvalu and Maldives will be wiped of the face of the earth by the mid-century.
