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.

According to the report, by 2050 two-thirds of people in the world will be living in cities and will be mainly concentrated in three countries - India, China, and Nigeria. Asia, despite its relatively lower level of urbanization, is home to 54 percent of the world's urban population, followed by Europe and Africa with 13 percent each. The global rural population is now close to 3.4 billion and is expected to rise slightly and then decline to 3.1 billion by 2050.

Smaller towns with populations under 1 million (Tier 2 and 3 cities in India) people will see the biggest population explosions, according to this year's study.

Speaking at a United Nations news conference, he said:"Managing urban growth to insure that it is sustainable has become one of the most important development challenges of the current century".

Cairo, Mumbai, Beijing and Dhaka are all closing in on the 20-million inhabitant mark. In 1990 there were just 10 megacities, classed as places with populations of 10 million or more.

The News Agency of Nigeria (NAN) reports that DESA in earlier report said: "By 2050, the third most populous country will be Nigeria, which now ranks seventh, and which is poised to replace the U.S.".

Meanwhile, reported that the National Population Commission (NPC) had put Nigeria's current population at 198 million people with urban population growing at an average annual growth rate of about 6.5%.

Based on the report, Tokyo's population is predicted to begin declining by 2020, while the Indian capital of New Delhi will become the most populous city on the planet by 2028.

About 90% of the world's rural population live in Africa and Asia. However, some of the fastest-growing urban agglomerations are cities with fewer than 1 million inhabitants, many of them located in Asia and Africa. DESA stresses that sustainable urbanisation is essential to successful development.

"When urban growth is rapid, insuring access to housing, water, sanitation, electricity, public transport, education and health care for all is especially challenging", Wilmoth said at a United Nations news conference.

The report added that linkages between urban and rural areas would need to be strengthened, building on their existing economic, social and environmental ties.
