Since the Internal Displacement Monitoring Centre (IDMC), a non-governmental organisation based in Geneva, started collating data on persons displaced by disasters in 2018, this set of the population has been increasing. By the end of that year, some 1.6 million people displaced by disasters were still in camps or places away from their homes. The World Migration Report 2020, published by the International Organisation for Migration (IOM) of the UN, had established the role of natural disasters in migration, saying: “Many more people are newly displaced by disasters in any given year, compared with those newly displaced by conflict and violence, and more countries are affected by disaster displacement.”

According to its latest version entitled The World Migration Report 2022, in 2020, 30.7 million new displacements were triggered by disasters in 145 countries and territories. The total internal displacement due to disasters, conflicts and violence has increased in comparison to 2019. The report quoted the regular data collation by the IDMC. The latest figure on new displacement covers those who have been displaced due to sudden-onset disasters and within the respective country.

However, according to IDMC, data was still not complete in case of displacement due to slow-onset disasters and inter-country displacement. In fact, most of the new displacements are due to climate–related events. Status of global internal displacement (2020) is given in the table published here: The World Bank’s Ground swell Report of 2021 estimates that by 2050, 216 million people will face internal migration within their country, with the majority of these migrations happening in sub-Saharan Africa. Countries like India, Bang – ladesh and China along with numerous countries from the Southeast Asian regions will also be impacted by the rising sea levels.
