Yellow River Delta
• Biodiversity increased Rare fishes reappeared, saury, bronze grudge etc.New habitats for birdsfrom 187 species in1992 to 300 species in 2010More Rare wild animals , 459 kinds found in the reserve, nearly doubledWetlands vegetation increased

Yellow River Delta
• Equality of water use
• Water savingWater use efficiency
In 1997, water used was 560 m3 for 10thousand RMB GDP,
in 2003, 309 m3, up 45%
Water used fall down
Inner Mongolia, 6.491billion m3, down to 5.952 billion m3
Shan Dong, 8.745 billion m3, down to 6.625 billion m3
• Economic boostBasin GDP Increase average 30.9 billion RMB/year
Social-Economic Sustainability
Achievements (Con.)
• YRCC Won 2010 Lee Kuan Yew Water Prize
• UNESCO—Yellow River Case published in WWDR3&4
• Asian-Pacific Knowledge Hub —Center of Hydroinformatics for Integrated River Basin Management (CHIRB)
