Pilot case: Wall-to-Wall coverage of Uganda

Wall-to-wall mapping

Now complete for the entire country

In 2015 Forest Vision did a wall -to wall mapping of Uganda.

FINDINGS: On average, the forest height has decreased by 33 cm during 2000–2012.

This forest height decrease represents a forest carbon loss, which corresponds to an annual CO2 emission of 27.1 million tons.

We have calculated the uncertainty of this estimate as a 95% confidence interval of ± 10 million tons.

Comparing the findings from InSAR data to data based on Landsat, we can see that the real gains inside the protected areas of Uganda are hardly detected, while the losses correspond well to the InSAR data.

InSAR technology gives a more complete image of forest height changes.
