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.
Spotting Brittany’s ‘Green Tides’ from Space
‘Green tides’ of algae have wreaked havoc across the coastlines of Brittany, France, for half a century due to high levels of agricultural runoff. With efforts to reduce these underway, a new technique using over three decades of satellite images highlights the extent of the continuing problem.
South Asian Farmers Fine Tune When to Water with Landsat
Putting NASA and USGS satellite information at farmers’ fingertips leads to less water use and better crop yields in South Asia.
Earth Day Connections: NASA Investigates Vegetation
Scientists use Landsat to track changing patterns of deforestation that tells them how Amazonian agricultural practices have changed, from small family holdings to massive ranching operations.
Keeping a Dry Eye on Drought in East Africa
The SERVIR team has developed models for groundwater demand based on Earth observations for parameters like rainfall and surface water from satellite missions.
From Space to Farm
Farmers rely on the accuracy of a crucial NASA and USGS mission, Landsat, to make decisions about crops.
Satellite Imagery Helps Farmers Cut Water Use in Half
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.
