The Niger River, which provides water to many countries in subsaharan west Africa is drying up, according to the BBC. http://news.bbc.co.uk/2/hi/africa/7375109.stm. This will cause hardship for the millions of people who depend on the Niger's water for agricultural, industrial, and residential use.
According to an alarmist study, increased man-made Global Warming would add moisture to this area. http://news.bbc.co.uk/2/hi/science/nature/7227080.stm ("Greening of the Sahara/Sahel").
