Final answer:
Building storm cellars and wind-resistant structures, using more radars and satellites, and encouraging water conservation can help reduce the effects of tornadoes.
Step-by-step explanation:
The techniques that can help reduce the effects of tornadoes include building storm cellars and wind-resistant structures, using more radars and satellites in the area, and encouraging citizens to use water conservation devices. Storm cellars and wind-resistant structures provide a safe place for people to take shelter during a tornado, while radars and satellites allow for improved monitoring and prediction of tornado formation. Water conservation devices can help minimize damage by reducing the strain on water resources during and after a tornado.
