Facts and figures about China – the Yellow River Basin

  • The Yellow River is the second longest river in China after the Yangtze River, and the sixth longest in the world. Originating on the Qinhai-Tibetan plateau in western China, it runs for some 5,500 km across the vast North China Plain, traversing nine provinces before draining into the Bo Hai Sea.
  • Its catchment area of 795,000 km2 is home to 110 million people (2000) or about 8.7% of China’s population. (The figures increase to 189 million and 14.9% if the flood plain surrounding the lower reach is included.) In 2000, about 26.4% of the basin was urbanized. Read more

Did you know…? Facts and figures about Zambia

  • Zambia is a landlocked country in southern Africa, which mainly lies in the Zambezi River basin, and partially in the Congo River basin in the north.
  • Between 2000 and 2007 Zambia experienced unusually unstable weather, with a sequence of two flood years, two drought years and two years with normal rainfall.
  • Zambia’s surface water potential totals some 100 billionm3, with the Zambezi River contributing over 60% of the runoff. Consequently, as a major stakeholder in the Zambezi River Authority, along with Zimbabwe, Zambia is helping establish the Zambezi Watercourses Commission. Read more

Did you know…? Facts and figures about Istanbul

  • Istanbul, located in northwestern Turkey, has a population of over 12 million. Home to 17.6% of the country’s population, it is the largest city in Turkey and one of the 25 largest in the world.
  • Although data do not indicate a clear declining trend in rainfall in Istanbul and its surroundings, extreme events – especially droughts – seem more pronounced than in the past. In 2006, the measured rainfall of 66.7 mm was the record low for the previous 50 years, a period during which the average was 257.2 mm per year. Furthermore, the water level in reservoirs serving the city was just 45% in 2004, and plummeted to around 25% in 2007 and 2008. Read more

Did you know…? Facts and figures about the Walawe River Basin (Sri Lanka)

  • The Walawe River basin, located in the southeast, has an area of 2,500 km2 and covers 4% of the total landmass of the Sri Lanka, it is one of the nation’s biggest basins.
  • Recent water resources development has linked some adjacent small river basins to the Walawe basin. Thus, the total area covered in this study is 3,300 km2 and includes the Malala Oya, Kachchigal Oya and Karagan Oya. Read more
