The province of Yunnan, China is experiencing a record-breaking drought that has been deepening since September 2009. River water levels, including the mighty Mekong, are subsiding well below normal, and many reservoirs are nearly dry. Millions of people, as well as agricultural activities in the province are affected due to severe water shortages.
