CBERS Satellites Track Soil Loss Across China

Soil erosion is a major environmental headache in China. It triggers landslides, reduces farmland, and harms water quality. Scientists have been looking for better ways to watch it.

A team turned to the CBERS satellites, a joint project between China and Brazil. The satellites give clear pictures of plant cover and how land is used. They also pulled slope information from a digital elevation model.

Using a standard erosion classification, they built a model that mixes vegetation, land use, and slope. The model spits out maps showing where erosion is mild, moderate, or severe. Those maps help pinpoint hot spots.

The work shows that CBERS can do more than just crop monitoring. It can become a regular tool for tracking ecosystem health across large areas. More agencies are now considering it for routine checks.
