True or false: scientists believe that over grazing and inappropriate farming techniques can make the air above the ground drier and warmer â and therefore less likely to generate rain clouds, thus influencing drought in a region.

Overgrazing happens when the animals or livestock feed on pasture when there is no vegetation present. Overgrazing has devastating impact on the environment as drought can strike any time and lack of precipitation means that farming in that area will also be impacted. The amount of rain received is not under the control of farmers and when the drought conditions extend the replenishment of pasture will not happen. Lack of precipitation will cause the plants to die and eventually the livestock feeds on the available plants to survive.

Plants, trees or crops help in increasing the amount of rainfall by the process of transpiration which is a process in which plants loose water as vapours during the photosynthesis. This water released by the plants increases the moisture content of air making the air saturated and brings about rainfall.
