Madrid (AP) -- Politicians and experts met in Madrid on Friday to discuss ways to tackle drought and the increasing spread of deserts across the globe.
"The consequences of drought can affect up to three quarters of humanity by 2050. There is nowhere to hide if we are unable or unwilling to avert the severe alterations we are inflicting on the planet," Ibrahim Thiaw, executive secretary of the U.N. Convention to Combat Desertification, or UNCCD, said at the opening of the meeting.
