In this USGS Landsat in Action video, Martha Anderson, with the U.S. Department of Agriculture, talks about the value of Landsat and its thermal data for understanding agricultural lands.
Quote to note:
“With Landsat we can see temperature of individual fields and how it varies from field-to-field. The temperature of the land surface gives us a good indication of how rapidly water is evaporating off that surface. And this is really important for knowing how healthy the crops are and also for supplying information for irrigators: how much water was used last week and how much do they need to replenish in the current week to keep the crops healthy.”
Satellites offer a wealth of information pertinent for water and food security. Landsat has long been a foundational piece of the “Space for Ag” initiative.
