An Indian born researcher takes on the mission of saving German forests and making them more resilient to climate change. Somidh Saha is at the Karlsruhe Institute of Technology. In this video from DW.com he shows what is being done in Germany to protect forests. 

Woodlands are under threat worldwide from urbanization and industry.

About 80% of German trees are not in good health according to a German government study. Damage is shown being done by the bark beetle to trees already weakened for other reasons including drought.

Saha says one has to be careful in evaluating how much of a country's space is healthy forests. In India he says it is sometimes said that 21% is forest land. Yet this includes plantations of many kinds- tea, rubber, coconut and so on. The healthy part of forests of high quality and suited to wildlife is a much smaller part of India.

The COP26 in Glasgow was unique in one way- for the first time a zero deforestation target was set for the world. World leaders promised to end deforestation by 2030. Protecting forests protects the planet from climate change as forests act like a carbon sink.
