Landsat's Role in Agriculture and Food Security
Worldwide, millions of people are helped by Landsat-data-based decisions that impact food and water management. Food and farming organizations rely on the unbiased, accurate and timely information provided by Landsat satellites. The data enable people to analyze the health and vigor of crops as they mature over the growing season; the needs of specific fields for fertilizer, irrigation and rotation; planted acreage to forecast crop production and fight crop insurance fraud; how much water is used in irrigation; and the impacts of drought.

Satellite Data Help Australian Ranchers Meet the Rising Demand for Meat in a Changing World
When Russell Lethbridge walks his property in northern Australia — kicking-up clouds of dust that catch the sunlight as he assesses the grasses, shrubs and brush that fill the landscape with muted tones of green — he carries the legacy of five generations before him on his shoulders.

Future Grains
When global food prices spiked dramatically in late 2007 and into 2008, the costs of many basic dietary staples doubled or even tripled around the world, sparking protests and riots. Panicked governments stopped exporting food, aggravating the crisis.

Tracking Agricultural Water Use on a Smartphone
This fall scientists at the University of Nebraska, with partners at Google Inc., the University of Idaho and the Desert Research Institute, introduced the latest evolution of METRIC technology—an application called EEFLUX, which will allow anyone in the world to produce field-scale maps of water consumption.
