- Desalination
- Sewage recycling
- Cloud seeding
F2 - SEM1- What is drought - 4.3
What is the function of reservoirs and dams?
F2 - SEM1- What is drought - 4.3
store water for daily use

What is the additional function of Qingcaosha Reservoir in Shanghai?
F2 - SEM1- What is drought - 4.3
purifies water from Chang Jiang
F2 - SEM1- What is drought - 4.3
How does Afforestation increase water supply?
F2 - SEM1- What is drought - 4.3
increase vegetation covers
> increase water infiltration > groundwater recharge
> increase transpiration from tree > formation of rain
F2 - SEM1- What is drought - 4.3
What is Desalination?
F2 - SEM1- What is drought - 4.3
technology that turns seawater into freshwater
F2 - SEM1- What is drought - 4.3
