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.
Landsat allows herders to monitor vast expanses of desert in a way traditional field monitoring can’t support.
BBC’s Follow the Food documentary series has reported on Earth observations supporting food production, market stability and on-farm decisions.
New Michigan State University research found that incorporating in-season water deficit information into remote sensing-based crop models significantly improves corn yield predictions.
Researchers at North Carolina State University have developed an automated technique that uses Landsat to determine when swine waste lagoons were constructed and how they may have affected environmental quality.
