Since 1997 CIFOR has called Indonesia its home. The sprawling country, spread over 17,000 islands, provides a rewarding base for forest researchers. It’s home to the world’s third largest rainforest, has half of the world’s peatlands and a quarter of its mangroves. All of these have provided the world with carbon sinks for millennia. Now, whether they mitigate or accelerate climate change- brought about when their centuries-old stored carbon is released into the atmosphere on their destruction – lies in their immediate management.
