Landsat's Critical Role in Agriculture
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 images are helping to reveal how COVID-19 lockdown measures are impacting food security, urban surface heat, water quality and aquatic ecosystems, and more in NASA-funded studies.
Grape growers like Gallo are using data from Earth-observing satellites to better track soil and vine moisture levels, understand vine water use and plan grapevine irrigation.
A new satellite-driven biophysical model can make accurate forecasts of crop water use that are critical for farmland water management and sustainability.
