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.
Remembering Robert B. MacDonald
Earlier this year on Jan. 7, 2014, a giant in the world of Landsat applied science— Robert B. MacDonald—passed away. MacDonald was largely responsible for first envisioning and formulating how to use early Landsat data to estimate global crop production.
1977 Video: Landsat—Satellite for all Seasons
This 1977 NASA video series, “Landsat—Satellite for All Seasons,” provides examples of early Landsat applications.
NASA 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.
Mapping the World with Landsat
Speeding around the Earth at 16,800 mph (27,000 kph), two Landsat satellites are quietly, expertly watching and recording changes in Earth’s lands from space. They are gathering data for people to make maps–all kinds of wonderful maps–of our cities growing, rivers flooding, lava flowing from volcanic eruptions, forests expanding or shrinking, crops greening through the growing season, and even of evidence of pollution.
Landsat Impedes Crop Insurance Fraud
With unbiased Landsat imagery as evidence, the U.S. Court of Appeals for the 9th Circuit affirmed an earlier jury-conviction of a northern California farmer found guilty on 16 counts of filing false federal crop insurance claims—scheming the government out of $410, 372.
