Media Advisory: How Will We Sustain a More Populated Planet?

Expanding demand from a growing world population — now numbered at over 7 billion — exerts unprecedented pressure on global resources, especially forests, water, and agriculture. Observing our world by remote sensing satellites enables scientists around the world to detect the most critical trends in natural resource conditions at local to global scales. Since 1972, the Landsat Earth observation satellites have monitored changes at the Earth-s land surface, including changes in forests, water bodies and agricultural and urban areas.

Using the nearly 40 year global Landsat record in combination with other Earth observation systems and the latest scientific techniques in Earth imaging, experts in mapping and monitoring our planet will describe present conditions and outline the future of many of Earth’s natural resources

Who:	Experts on mapping and monitoring the globe by Earth observation from space: Alan Belward, European Commission Joint Research Centre Matthew Hansen, University of Maryland, College Park James Irons, NASA Goddard Curtis Woodcock, Boston University Thomas Loveland, U.S. Geological Survey, moderator
Where:	18th William T. Pecora Memorial Remote Sensing Symposium Hilton Washington Dulles Hotel, Potomac Ballroom Herndon, VA
When:	November 16, Wednesday Noon
Call-in info:	US Reporters 888-469-0941 Outside US 415-228-3913 Pass code: Landsat

Video of the press briefing will be streamed live online.
