Summary: Nearly 85 million people around the world are currently considered “food insecure,” and that figure continues to grow. Remote sensing technology enables scientists to feed data into the Famine Early Warning Systems Network (FEWS NET), which in turn can issue alerts that guide the distribution of humanitarian aid. In this episode of Eyes on Earth, we hear from an EROS climate scientist who works with the Network to predict drought and famine.

Guest: Chris Funk, USGS EROS Research Geographer

Summary: Every year, the USDA’s National Agricultural Statistics Service (NASS) uses data from satellites like Landsat to estimate crop types and crop yields in the United States. The result is the Cropland Data Layer (CDL), which offers an annual look at more than 100 crop categories across the country. In this episode, Dave Johnson with NASS discusses how Landsat can identify different crops, providing a valuable economic tool for agriculture.

Summary: EROS scientists track water availability and crop health around the world to help governments and non-profits manage resources and stave off food shortages. But EROS also teaches international scientists to track those resources themselves. In this episode, we hear about a recent training session at EROS for Iraq’s Ministry of Water Resources.

Summary: Earth observation used to be the province of a handful of countries with satellite technology. Today, hundreds of satellites are built all over the world and launched every year. This episode of Eyes on Earth talks about the explosive growth in the civilian and commercial remote sensing and EROS’ role in it.
