Over the last few years, researchers and policy makers are showing their interest in measuring the impact of climate change on migration and human displacement. It is projected that by the next 40 years, around one billion of the world population may move from their own place that has been affected by climate change (Laczko & Aghazarm, 2009). Already it is evident that some parts of the world have become less inhabitable than other parts due to climate change and its effects, such as desertification, pollution, natural disasters or decline of agricultural productions.
