A Conservation-Based Future in Colombia

A.J. Rohn

By properly including indigenous and impoverished peoples in the new economy and securing communal land rights in the forests, as well as fostering soil recovery in areas of coca cultivation and managing resource extraction, Colombia can move into a more equitable and environmentally sustainable future.

Using LiDAR to Show How Native American Depopulation Impacted Forests in the United States

Elizabeth Borneman

Researchers have used LiDAR to understand the impacts of Native American population decline on forest fires in the United States.

Since January 1, 2000, more than 4.3 million scenes have been captured by Landsat satellites and made available to the public. Graph by Joshua Stevens, using data collected from the U.S. Geological Survey acquisitions archive.

Cloud Computing Used to Analyze Landsat Imagery and Detect Deforestation

Zachary Romano

Landsat, NASA’s longest running initiative for the acquisition of Earth imagery, has generated nearly 50 trillion pixels of data by capturing one image per season, of every place on Earth, for the past 43 years, providing a treasure trove of data for researchers.
