What is the importance of forest ecosystems? How big is the issue with forest degradation? Which solutions exist and are being applied today?

Check our selection of videos, interviews with experts and practitioners or our short explainers, to get the answers to these and other questions.

We’ve selected information from specialist sources, adapted for a non-specialist audience, with text, images and videos. For those interested in learning more or in going directly to the source of the information, please follow the links we provide. This information can be used and shared freely.

Remember: Trees offer a natural mechanism to help lowering the amount of atmospheric CO2 , a global challenge. At the same time, mature trees generate many other important benefits – some of which are critical for our societies and livelihoods – pretty much for free.

This video from WRI’s Global Restoration Initiative provides a good overview of the issue and their initiative to restore degraded landscapes and forests worldwide, together with governments and international partners.

But palm oil is also a critical industry, involving small farmers & multinational companies, governments and international investors. As this video shows, any attempt to improve the current situation must deal with all these levels and realities.
