“whereas the size of cities in India and Africa is driven primarily by population growth. “Rising incomes translate into rising demand for bigger homes and more land for urban development”
I am glad to see that incomes in Africa are rising given that the emphasis on bio-fuels is causing African children to die of starvation by the thousand …
Mankind is using less that 20% of the land area on this planet – http://en.wikipedia.org/wiki/Land_use_statistics_by_country
Seems like yet another scare mongering attempt. I am old enough to remember when research grants were given for looking at ways to make life better for everyone.

David Schofield says:
London [quite a pleasant sprawling city] is 160 sq miles with a population of 8,000,000
Mongolia is 604,000 sq miles
You can get 3775 Londons in Mongolia x 8000000 pop = 30 200,000,000 or over 30 billion.
In fact the whole world [7 billion] could live in 875 Londons requiring 140,000 sq miles which is around half the size of Texas and leave the rest of the world completely empty.
If you replaced London with a denser packed city it would be much higher.
Again these people talk utter tosh.
PS I’ve just woken up and this took me 3 minutes so any arithmetical corrections welcome, but you get the principle.
“I am glad to see that incomes in Africa are rising “
At the expense of the American taxpayer.
