Sep 26, 2014Modeling a Changing American Landscape

Land change is a signature activity of human civilization. Since the dawn of history, people have purposefully converted natural landscapes to human-dominated areas. Typical motivations for land change are cultivation (e.g. slash-and-burn fields, rice paddies, modern farms); occupation (villages, cities, housing developments); and other cultural and economic pursuits (roads, schools, airports).

Aug 21, 2014Landsat and Water: Using Space to Advance Resource Solutions

A recent White House-led assessment found that Landsat is among the Nation’s most critical Earth observing systems, second only to GPS and weather. A new USGS study, Landsat and Water — Case Studies of the Uses and Benefits of Landsat Imagery in Water Resources, provides examples of why Landsat is so valuable.

Jul 23, 2014Landsat’s Role in Water Resource Management

Water availability and allocation are issues gaining a great deal of attention, particularly in arid climates. Increases in population growth and recent droughts bring urgency to measuring and monitoring water use in areas such as the western United States, where the majority of the water has already been allocated.

Feb 4, 2014NASA Maps Earth’s Croplands from Space

It takes a lot of land to grow food for the world’s seven billion people. About a third of Earth’s terrestrial surface is used for agriculture. And about a third of that, in turn, is used to grow crops. Now, a new NASA-funded effort aims to map crop fields worldwide, identify what’s growing where, and determine whether it’s irrigated or fed by rain.
