The issue of poverty …show more content…
In some ways, one of the reasons for the occurrence of migration is because of environmental changes in a country. As stated by Afifi in his article that the increase in sea level, droughts, increases in tropical hurricanes and frequency of heavy rains and flood is the threatening potential causes of migration (Afifi, 2010). This somehow demonstrates that it shapes the pattern of vulnerability especially those who lived in poor condition of environment and overpopulation country (Afifi, 2010). However, as pointed out by Kniveton (2008) in his article stated that the environmental change or any natural disaster such as Hurricane Katrina, only affected society if there are highly dependent on the environment and if human action worsen the environmental aspect of the disaster, hence migration takes place. Furthermore, it demonstrates that society experiences high vulnerability. In Alaska, it experiences a situation of decreasing in the thickness of sea ice, which affects the indigenous communities (Afifi, 2010). These communities are threatened due to environmental change such as accelerated rates of erosion and flooding. The government is striving to solve this issue, as conventional adaptation strategies of hazard preventions are no longer protecting the communities. Hence, relocate them are necessary. Another example would be in Hong Kong, there are trends of rural depopulation through migration to coastal urban centers in the 20th Century (Yim, 1993). A rapidly growing number of coastal mega cities could lead to certain circumstances such as overcrowding and vulnerable to varieties of weather-induces hazards including, typhoons, landslides and floods (Yim, 1993). The government faced a greater future concerns, as due to overcrowding, the level of vulnerability in the mega cities increases such as the issue of floods and landslides. This is because of increase in the
