Impact on Source and destination regions

Overcrowding of people due to rural-urban migration has put pressure on the existing social and physical infrastructure in the urban areas. This ultimately leads to unplanned growth of urban settlement and formation of slums and shanty colonies.

Movement of people from ‘low-carbon’ to ‘high-carbon’ parts of the world will cause an absolute increase in GHG emissions if migrants from ‘low-carbon’ areas increase consumption of carbon-intensive products once they have migrated. For example aviation industry which is highly carbon-intensive is bound to grow with migration.

Apart from this, due to over-exploitation of natural resources, cities are facing the acute problem of depletion of ground water , disposal of sewage and management of solid wastes.
