Sri Lanka is one of the South Asian countries which is negatively affected by the climate change. This includes natural disasters such as flood, earth slips, cyclones and droughts etc. These unexpected and unforeseen disasters not only dislocate the people from their dwellings but also make a significant negative impact on their livelihood.

The continuous experiences of these tragic situations due to the climate change compels the affected people to migrate locally and overseas for their safety and economics benefits. This situation has resulted in a very high level of population density in the urban areas especially in the Western Province of Sri Lanka.
