What are some key facts about the Grand Ethiopian Renaissance Dam? (An example of water conflict)
• Located 30km south of the Sudan border on the Blue Nile (85% of Nile water)
• More than 1 mile long, 145m high
• 12 years of construction, £3.8Bn cost
+ Provides electricity for 60% of the population, x2 Ethiopia output of electricity
+ Provide electricity for neighbours (e.g. Sudan, Kenya)
- 2% reduction in Nile water= 200,000 acres of irrigated land lost for countries downstream
- Little agreement on use of water
- Construction started during Arab Spring
- Armed conflict is possible between Egypt and Ethiopia

• Started construction in 1993, finished in 2009
• Flood control, navigation, HEP, drinking water
+• Prevents downstream flooding (e.g. Shanghai)
+• Ship lift allows upstream trading
-• Sedimentation= reduced carrying capacity of the reservoir
-• Environmental laws are weak, therefore pollution
