TWO out of every three people will live in cities by 2050, giving rise to the creation of megacities predominantly in China, India and Nigeria, according to a United Nations report released Wednesday. The report by the UN's population division goes on to say that while the global rural population will steadily increase and reach its apogee in a few years, the trend will decline by 2050.

Shanghai will continue to be the world's third-biggest urban area with a population of 33 million in 2030 and Dhaka will be fourth with a population of 28 million, followed by Cairo with 26 million, according to the data. Urbanization will lead to a decline in Russia's rural population from 36.8 million to 22.1 million.

India, China and Nigeria are expected to account for 35% of this projected growth in urban population from 2018 to 2050. It said that after surging past Tokyo in 2028, the population of Delhi urban agglomeration would grow to 39 million by 2030 from 29 million now. Tokyo, with 37 million people, is now the most populated city, followed by New Delhi with 29 million, Shanghai with 26 million and Mexico City and Sao Paulo, each with around 22 million dwellers.

"Economic contraction and natural disasters have also contributed to population losses in some cities", the report said.

A few cities in Japan and the Republic of Korea (for example, Nagasaki and Busan) have experienced population decline between 2000 and 2018.

The report also estimates that by 2030, the world could have 43 so-called megacities (up from 31 today, according to reports) - those with more than 10 million inhabitants - majority in developing countries.

"The increasing concentration of people in cities provides a way of more economically providing services", he said. Currently, India's 1.3 billion population is split with just under 900 million living in rural areas and around 460 million in its cities.

Megacities are set to dominate in India and China as world urban population increases.

Megacities are those with more than 10 million inhabitants and the reports says a lot of them would be in developing countries.

"Many countries will face challenges in meeting the needs of their growing urban populations, including for housing, transportation, energy systems and other infrastructure, as well as for employment and basic services such as education and healthcare". Integrated policies to improve the lives of both urban and rural dwellers are needed, while strengthening the linkages between urban and rural areas, building on their existing economic, social and environmental ties.
