Drought

Droughts occur when areas receive less rainfall than expected over an extended period of time, usually several months or longer. All areas in the United States are at risk of drought. A prolonged drought can have a serious impact on agricultural communities, affecting crops, livestock and families dependent on these commodities. The greatest impact from drought is of course the decrease in water supplies. This can result in crop loss and reduce crop and forage growth and availability. The impact on livestock is equally devastating, and can result in animal deaths from limited water supplies or feed availability. Plants can also concentrate toxins under drought conditions, making them more lethal to livestock. Drought conditions can also increase the level of disease and insect infestations for plants and livestock. The dry conditions can also lead to wind erosion of top soil, or increase the risk for fire hazards, and given decreased water sources, can result in devastating losses. Families and businesses can also be impacted by limited or restricted water sources during drought situations.

The following resources will help you prepare your family, home and farm, animals and business for drought situations.
