Why would you expect that? Is someone predicting that worldwide standards of living will rise to US/European standards in under 100 years? Is someone predicting a vast war or global pandemic? I don't see any demographic trends that would lead to decreased world population.

U.N. sees world population decline by 2050
August 1, 2009
A United Nations report predicts that within less than a decade, most of the world's women will be producing fewer than two children, and by mid-century, the world's population will shrink for the first time since the Black Death in the 14th century.
Currently, world fertility is only half what it was in the 1960s.
The prevailing wisdom holds that, as nations develop their economies, women will increasingly favor conventional families of two parents and two children, stabilizing the human race at 10 billion to 12 billion people compared with 6 billion today.
But now it appears more likely that world population will peak at just 8 billion, then shrink in the second half of the century, says the U.N.
Joseph Chamie, who directs the U.N.'s population division, reports that fertility in more than 60 nations is already below replacement levels and that actual population decline has been postponed only because people are living longer.
By some estimates, the world's population will be cut in half within the next 1½ centuries. In Mexico, Brazil and India, birth rates are plummeting. In Africa, AIDS has cut average life expectancy by more than 10 years.
