Abstract

In 2005, a hurricane named Katrina hit the states of Louisiana and Mississippi in the US, destroying properties and flooding areas. Many people left the region and still have not returned. While some of these people may eventually return, some may not, becoming “migrants.” Assuming this phenomenon will occur, is it unique? What is the role of the environment in migration? Can there be violent conflict between such migrants and residents in areas absorbing migrants? We evaluate these questions in the cases of Hurricane Katrina, the US Dust Bowl in the 1930s, and Bangladesh since the 1950s, demonstrating that environmental change can trigger large out-migration, which can cause violent conflict in areas receiving migrants. These findings have important policy implications. Climate change is expected to degrade the environment considerably in this century. Minimizing climate change-induced migration and violent conflict in receiving areas requires an engineered economic slowdown in the developed countries, and population stabilization and economic growth in the developing countries financed by the developed countries.

Notes

  1. Wars and genocides can also cause many people to move at once.

  2. For example, implications from the cases I present may not apply to cases of migration caused by industrial accidents or development projects, such as the Chernobyl nuclear accident, which permanently displaced 231,000 people (UNDP 2002), and the Three Gorges Dam project, which permanently displaced 1.4 million people by 2007 (BBC News, 26 January, 2007) and may displace 2 million by 2009 (IRN 2003).

  3. See also Homer-Dixon (1999), Barashi (1991), and Boyce (1990).

  4. About 1–2 million of these people moved due to the 1971 war (Homer-Dixon 1999).

  5. Additional casualty data were recorded as follows: 3,000 before 1983, Swain (1996); in 1983, 3,000–5,000, Suhrke (1997); in the early 1980s, 4,000–5,000, Hassan (1991).

  6. For other total loss estimates see NOAA (2006), $125 billion; McQuaid (2006), $150 billion; and Burton and Hicks (2005), $156 billion.

  7. Assessments of total areas vulnerable to innundation are not available for all countries. For Canada, for example, studies focus only on select regions (IPCC 2001a).

  8. Deported aliens include those arrested upon entry or on US soil, and (before 2004) criminals.
