A United Nations estimate foresees that India’s capital city Delhi is likely to turn into the most populous city in the world by 2028 and that India will add the largest number of urban residents by 2050.

At present, Tokyo is the world’s largest city with population of 37 million and India’s New Delhi reeling behind with 29 million residents, closely followed by Shanghai with 26 million. Other global megacities with population above and around 20 million includes Cairo, Mumbai, Beijing and Dhaka. The United Nations’ 2018 Revision of World Urbanisation Prospects report predicts that by 2020, Tokyo’s population will start declining and will get down to about 36.8 million; whereas Delhi’s population will keep increasing to reach about 37.2 million to surpass Tokyo’s population by 2028 to become world’s most populous city.

Since decades, population in India hasn’t not increased in India and is inches close to becoming the most populated countries in the world – beating China. So it is not just about Delhi alone. As per the 2018 Revision of World Urbanisation Prospects rolled out by the United Nations, 68 percent of the global population will be living in urban areas by 2050 instead of 55 percent at present. But here’s the catch – this bolster in urban population is likely to be concentrated in few countries like India, China and Nigeria.  These countries will have a rise of 35 per cent in the world’s urban population between 2018 and 2050.

The UN report also suggests that by 2030, there will be 43 megacities in the world with a population of more than 10 million and most of them will be dwelling in developing regions. While having huge population has its own benefits, but there are more challenges with population exploitation.  Meeting the needs including basic facilities like housing, clean water, food, electricity, transportation, education, health care and employment becomes tougher. Solution? Avoiding population exploitation for a balanced world with space for us to live in.
