- Evaluate the view that some water management schemes are more effective than others (20 marks)
- Introduction
- No water management in place = increases water insecurity
- Hard Engineering Schemes
- Dam construction
- Desalination
- Water Transfer Projects
- Soft Engineering Schemes
- Smart Farming
- Rainwater Harvesting
- Water Reclaimation
- Hard Engineering Schemes
- Desalination
- Extracts salt water = safe, drinking water = increases water security
- BUT only developed in HICs as it is very expensive
- Water Transfer Project - China
- South-North China
- Provides 25 billion ^3 of fresh water
- Increases employment
- More than 300,000 displaced during process
- Dam Construction - Three Gorges Dam
- Yangzee River
- Increases globalisation = cargo space
- Provides power for China = reduces emissions
- Poor water quality
- Desalination
- Soft Engineering Schemes
- Smart Farming
- China and Australia
- measuring intra-field variability in crop fields
- Vertical Farming - Kent
- Cultivating plants without soil +water is recycled
- China and Australia
- Rainwater Harvesting
- Harvesting jars collect rainwater from roofs + store water
- Holds 1500 litres approx
- Harvesting jars collect rainwater from roofs + store water
- Water Reclamation
- Removes objects, sediment, bacteria
- Water is then treated then put through microfiltration
- Reverse osmosis and then microscopic contaminants are removed
- Water is then treated then put through microfiltration
- Removes objects, sediment, bacteria
- Smart Farming
- Conclusion
- Although HES are effective and increase water security
- Expensive and can only be implemented in the more developed regions
- If everyone could implement soft engineering methods like rainwater harvesting
- would be effective in areas with high precipitation rates (UK)
- Households become less dependent on companies to supply masses of water = cheaper in long term
- Although HES are effective and increase water security
