Louisiana is the nation’s third-largest producer of rice, after Arkansas and California.
In 2021, the Rice Belt (Arkansas, Louisiana, Mississippi, and Texas) produced about 73%of all rice in the U.S. The map here shows rice-growing areas within these states (in blue) in 2022.
#NASAEarth
Our view from space can also show us how crops like rice are growing.
Satellites like #Landsat and Terra helped map a drop in rice acreage during a drought in Sacramento’s Central Valley – normally the largest rice-growing region in California.

When you think of NASA, do you think of...
Rockets or corn?
Space or wheat?
Mars or rice?
NASA data also plays a big role in the food we eat, from water management to sustainable farming processes.

The Corn Belt in the midwest is home to the nation’s most productive soils.
Hundreds of miles above, NASA satellites provide critical views of the region that help scientists study soil loss over time and develop tools for conservation techniques.

Many @nasaearth satellites use light to study Earth from space.
Light from the Sun bounces off Earth and to the satellite’s sensor. Each wavelength of light tells scientists something about the surface below. Julia and her team make sure those sensors are extremely precise.
#NASAEarth
Julia Barsi also works with the @NASA_Goddard GLAMR lab, where scientists test sensors before the satellite is sent to space.
They shine laser light at the sensor to see how it responds to different wavelengths. This information helps scientists interpret the satellite data.

NASA’s OCO-2 satellite helps track carbon dioxide emissions for more than 100 countries.
In this map, countries where more carbon dioxide was removed than emitted appear as green depressions, while countries with higher emissions are tan or red and appear to pop off the page.

Counting Carbon Stored in African Dryland Trees
With the help of artificial intelligence and high-resolution satellite images, scientists mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests.Rob Garner (NASA)
#NASAEarth
The team found there are far more trees in semi-arid regions of Africa than previously thought. But those trees store less carbon than some models predicted.
They estimate roughly 0.84 petagrams of carbon are locked up in African drylands.
(1 Pg = 1 billion metric tons)
#NASAEarth
The data are publicly available with a viewer app developed by the team. #OpenScience
The app identifies individual trees in satellite imagery and shows the amount of carbon they contain.
