Borders have been conceptualized in two main ways. The “static border” is the fixed line on a map that separates one country from another. Post 1989, the concept of the “disappearing border” came into fashion, the notion that borders and their influence onhuman mobility would become increasingly irrelevant. In this video, AYELET SHACHAR argues that though contemporary borders are not static, they have certainly not disappeared. Proposinga model of the “shifting border”and analyzing the ways in which countries like the U.S., Canada and Australia have effectively moved their territorial borders in order to control human mobility, Shachar argues that if borders are dynamic, then human rights should be equally agile. Highlighting the dramatic effects that the“shifting border” can have for those seeking asylum, Shachar’s work pinpoints the central importance that debates around immigration have for contemporary conceptions of citizenship and national sovereignty.
