The team found there are far more trees in semi-arid regions of Africa than previously thought. But those trees store less carbon than some models predicted.
They estimate roughly 0.84 petagrams of carbon are locked up in African drylands. (1 Pg = 1 billion metric tons) #NASAEarth
But what is the prognosis about how many trees will there be in five, ten, twenty years? Are they increasing in number, are they spreading, or is the desert claiming more and more land?
