Human migration in the face of global climate change

On Thursday we (8A) got the opportunity to listen eagerly to a lecture by sociologist Dr. Raya Muttarak who works as the program director at the “International Institute for Applied Systems Analysis” (IIASA) in Vienna. The lecture which was conducted as part of the Styrian “Klimawissen Online” presentation series discussed one of Ms. Muttarak’s most recent research questions that addresses the link between human migration and global climate change. However, before connecting these two issues, one must take the main reasons for migration into account. In addition to economic motivations – such as the search for better professional perspectives – people also migrate for educational and family-related purposes. 
 
More severe causes for migration include local conflicts, the violation of human rights and natural disasters. The latter are an example for rapid onset events which pressure people to leave their home urgently because staying would involve certain dangers or the absence of safe shelter. Such sudden natural events (landslides, earthquakes, wildfires etc.) cannot be exactly predicted and thus cause so-called forced migration. On the contrary, slow onset events (sea level rise, inconvenient weather conditions etc.) follow a gradual evolvement and cannot be associated with one single point of time. They induce voluntary migration, but only after the population has already tried to adapt their lives to the changed circumstances. For instance, a farmer that lives in a region where climate change has caused less precipitation would always try to adjust his work at first by planting drought-resistant crops or by implementing an adequate irrigation system, before eventually deciding to migrate. The same applies to ski areas which often have to cope with a lack of natural snow as a result of climate change. Instead, they use artificial snow in order to prevent economic losses. To sum up, people tend to not leave their home until an adaption to the prevalent circumstances becomes impossible.
 
Anyway, the decision to migrate is in every case the product of several factors that influence one another. Therefore, measuring how many people migrate due to environmental reasons is a very complex process. Namely – when considering slow onset events – climate change is only an indirect motive. Nevertheless, one promising method is to compare climate and demographic data. That is basically what Dr. Muttarak’s work consists of and it already led her to the conclusion that certain migration movements are indeed linked to the effects of climate change.
 
Finally, we want to cordially thank our Geography and Economics teacher Ms. Wilding for organizing our participation at the lecture so spontaneously! Thanks to her efforts we were able to look beyond the obvious reasons of migration and once again realized the severity of climate change.
