Contemporary geographies of exclusion II: lessons from Iowa

Processes of exclusion both presuppose and reinforce boundaries. Yet the realities of globalization mean that such political and cultural boundaries are regularly and increasingly transgressed. Cross-border traffic is simultaneously encouraged and feared; migrants who are welcomed because of their labor are often shunned because of their difference. Because of the tensions generated by the inevitable co-mingling in everyday space between insiders and outsiders, the politics of immigration regulation are unusually fraught in the contemporary period. For this reason, the line between foreign relations and domestic politics is increasingly blurred. As states become more robust in their boundary enforcement practices, the political plight of migrants becomes more perilous. The recent literature on exclusion understandably emphasizes the politics and practices of immigration policing, with broader lessons that I use this review to elucidate.
