Abstract
BackgroundThis paper has reviewed the international research on the terms “climate change” and “human migration” from 1999 to 2019. To this end, a bibliometric and a cluster analysis by fractional accounting have been carried out using two of the most important databases: Web of Science (WoS) and Scopus. The research found and studied 140 documents from WoS Core Collection and 193 from Scopus.ResultsThe results show a continual increase in the number of articles published and citations received during the whole period studied. The U.S., U.K., Germany and China have been shown to be the most productive countries and there is a predominance of North American organizations supporting and fostering research on these topics.ConclusionsThe main contribution of this article is the analysis of new tendencies. The trend shows a transition from concepts such as vulnerability, climate change, land degradation, refugees and security to others such as concepts such as international migration, climate justice, sustainability, human rights and disaster risk reduction. Future research in this field should address the comparison of results from research focused on human beings to a focus on other living beings.
Highlights
Throughout the history of the planet, climate has undergone major changes which can be clearly verified in the geological record
Fang and Liu [18] entitled “Relationship between climatic-change and the nomadic southward migrations in eastern Asia during historical times” in which the basis for historical research on climate change-induced migratory movements are set from the analysis of nomadic migrations in South Mongolia and East Asia
The most striking data is found in 2007 in Scopus: with only articles registered, the total number of citations rises to 400. This is due to Reuveny’s work entitled Climate change-induced migration and violent conflict (371 citations) in which the conflicts that arise with the arrival of climate migrants in new territories are addressed
Summary
Throughout the history of the planet, climate has undergone major changes which can be clearly verified in the geological record. At present there is broad scientific consensus [14], practically universal, that our current model of production and energy consumption is responsible for the planet-wide climatic alteration, unprecedented in the history of mankind. While it is currently having a serious impact on both the environment and the world economy, everything indicates that it will be exacerbated in the future. This paper has reviewed the international research on the terms “climate change” and “human migration” from 1999 to 2019 To this end, a bibliometric and a cluster analysis by fractional accounting have been carried out using two of the most important databases: Web of Science (WoS) and Scopus.
