Changes in population growth, consumption and farming begin to return former farmlands to nature

Researchers led by Rockefeller’s Jesse Ausubel analyzed factors such as global land use and population growth over the last 50 years. Looking at the production index of all crops of the UN’s Food and Agriculture Organization, they found that from 1961 to 2009 land farmed grew by only 12 percent while the index rose about 300 percent.

New formula predicts how people will migrate in coming decades

Countries use population projections to estimate local needs for things like jobs, schools, housing and health care, but coming up with those projections has been an inexact science.

Genetic data from an island population proves to be useful tool in understanding disease

With fewer than 4,000 residents, the genetically isolated Micronesian island of Kosrae, in the West Pacific, provides an ideal population in which to research heritability of disease. Now this data is beginning to yield intriguing results about the genetic basis of complex disease. More »

It took from the beginning of time until 1950 to put the first 2.5 billion people on the planet. Yet in the next half-century, an increase that exceeds the total population of the world in 1950 will occur. So writes Joel E. Cohen, Ph.D., Dr.P.H., professor and head of the Laboratory of Populations at The Rockefeller University and Columbia University, in a Viewpoint article in the November 14 issue of the journal Science.

How Many People Can The Earth Support?

If the human population continued growing at the rate seen in 1990, the world would tally 694 billion people by the year 2150, the United Nations predicts. But that’s not likely, says Joel E. Cohen, Ph.D., professor and head of the Laboratory of Populations at The Rockefeller University. More »
