Rich countries need to put cash on the table to curb deforestation

Saving the world’s forests is essential to avoid runaway climate change, but the detail will only emerge after an agreement. It is harder than you might imagine to measure “net” deforestation – the difference between what is lost and what is gained.  Because while forest loss is quick and visible from year-on-year comparisons of satellite images, regrowth is much slower and less visible, says Peter Holmgren, director of CIFOR, an international forest research institute.
