Deforestation is a growing, human-made calamity. Over 47,000 km2 (an area almost twice the size of Wales) of forest is lost worldwide annually. In fact, 17 per cent of the Amazon rainforest has been destroyed in the past 50 years alone. But some countries have recently logged surprising increases in forest space.

Here are the top nations with the highest net gain of woodland per year:
