More people means more trees – this is the unexpected finding of an Oxford University research project in this West African country. The researchers found that the most thickly forested parts of the savannah regions are inevitably to be found surrounding human settlements. When villages are deserted the trees disappear and the savannah shrubland takes over. The evidence from photos taken in the 1950s backs their findings. The irony is that it took two academics to reveal what the local people knew all along.
