Extent <br />Drought impacts in a number of ways, spanning all regions, and is capable of affecting the <br />economy as well as the environment. Specific impacts can include reduced crops and <br />rangeland, increased livestock and wildlife mortality, increased fire hazard, diminished water <br />supplies for municipal /industrial, agricultural and power uses, damage to fish and wildlife <br />habitat, reduced tourism and recreational activities, reduced tax revenues because of reduced <br />expenditures, and foreclosures on bank loans to farmers and businesses. <br />The most direct impact of drought is economic rather than loss of life or immediate destruction <br />of property. While drought impacts in Texas are numerous and often dependent upon the timing <br />and length of individual drought episodes, the greatest impacts of drought are usually <br />experienced in the agricultural community. In addition to the obvious direct losses of both crop <br />and livestock production due to a lack of surface and subsurface water, drought is frequently <br />associated with increases in insect infestations, plant disease, and wind erosion. <br />.1 <br />
