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.
A young start-up is using satellite data to give California farmers better information about water, which can translate into water savings or bigger yield for the same input.
A new data set uses Landsat data to extend the Crop Data Layer back in time.
A new web-based platform called OpenET will soon be putting satellite data in the hands of farmers, water managers and conservation groups to accelerate improvements and innovations in water management.
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.
