Ten percent Sahara expansion

“The desert (Sahara) has expanded southward during summer by about ten percent, so it’s a fairly significant increase in the desert expanse over this 93-year period that we analyzed.  Most people in the region depend on the food they grow on small family farms. So losing farmland could have grave consequences, especially as populations continue to grow.”


“Nigam is a professor at the University of Maryland. He says decreasing rainfall is likely a result of both natural cycles and human-caused global warming.”


So there we have the kernel of the problem.  Decreasing small farmland and increasing population.
