The world has never witnessed such a great influx of population from rural areas to cities that it did in the last decade, and it is still ongoing. Cities are already over-populated, polluted and cramped with an overwhelming number of people. Only decentralisation and mandatory relocation can reverse the scenario.
To begin with, only 20 per cent of the world population lived in cities at the beginning of the 20th century while this has already escalated to over 80%. This over-population in cities increases the crime rate, contributes to environmental pollutions, declines the living standard of citizens, creates cut-throat competitions and makes living cost higher. The traffic congestion is a direct result of it that kills thousand of man-hours each day. Besides, the housing problem in cities is getting worse day by day. According to a recent study, the lifestyle of cities is declining faster with the dramatic increase of its population.
To stop people from moving to metropolitan areas, the government has to adopt an effective decentralisation policy. If enough civil facilities and employment opportunities are created in the rural and suburban areas, a few people would move to cities. People primarily migrate to big cities to have better careers and earning prospects. To reverse it, the government has to start big projects to empower the rural people and forcibly move many factories and facilities to nearby countrysides. Education, treatment and entertainment facilities in cities attract many rural people and the only way to stop this influx of people is to add those facilities to the countrysides as well.
In conclusion, cities become less habitable with the inflow of mass people who come to have a better life but eventually face more problems. Decentralisation could be a very effective solution to invert this concerning trend.
