Vancouver Sun - Satellites provide a larger view of hunger


A five-point plan to double our food supply faces serious obstacles, often because people don't want to give up what they have. When you take a satellite's-eye view, the world's food problem comes into clear focus: The planet's best agricultural land is not necessarily where the most people live.

Navin Ramankutty, a professor of geography at McGill University, and a team of researchers from Canada, Germany, Sweden and the United States have applied their minds to the problem and examined our food systems from a truly global point of view, combining crop records from around the world with satellite images to rate the world's inventory of productive land and map the devastating environmental impact of agriculture. The report was recently published in the journal Nature.
