Droughts

1. A drought is a prolonged period with little or no rainfall. A drought becomes a hazard when people, agriculture or industry are affected

2. How do humans make drought worse?

   • Deforestation
     • Means less evapotranspiration , fewer clouds , less rain and more soil erosion
   • Overgrazing
     • Less grass , more soil erosion
     • Lack of water, minerals and nutrients

3. Irrigation for crops means less water for other uses.

   • Need soil to be in good condition so that the land is fertile.
     • This also prevents flooding

4. Poor water management

   • Leaving tap on while brushing teeth
   • Golf courses using vast quantities of water
