The earth’s population could top nine billion by 2050, leading to an ‘unrecognisable’ world as people compete for scarcer resources a U.S. science conference heard yesterday.

The American Association for the Advancement of Science (AAAS) heard how the world’s population‘s will increase rapidly in poorer countries resulting in the need to produce the same amount of food in a 40 year period as had been produced in the previous 8,000 years.

Population growth is expected to be highest in African and South Asian states, while incomes are also expected to rise in these countries by up to four times.

Demand: Huge increases in the populations of African and South Asian countries will result in the need to produce the
same amount of food in the next 40 years as in the previous 8,000.

This will lead to further strain as research has shown that people earning higher wages consume more food.

“More people, more money, more consumption, but the same planet,’  Jason Clay of the World Wildlife Fund told the AFP news agency.

‘By 2050 we will not have a planet left that is recognisable,’
