USGS Research Geographer Prasad Thenkabail gives a free talk on how remote-sensing from space will provide crucial data for policy development on croplands and their water use.

A free publiclecture by USGS Research Geographer Prasad Thenkabail
Worldwide demand for food will requiremore than 1 billion hectares of new cropland to feed 9 billion-plus people by2050. Presently, of all the water used by humans, more than 70 percent goestoward agriculture to produce food in most countries. Remote-sensing from spacewill provide crucial data for policy development affecting croplands and theirwater use. Social scientists recognize global food security as a primaryrequirement for human advancement, overall health, and peaceful coexistence.
