drought causes and effects

People are forced to shift to other places in search for better living conditions during droughts. Changes in water quality, such as increased concentrations of contaminants, can threaten persons whose immune systems are compromised. If dry weather persists and water-supply problems develop, the dry period can become a drought. During dry and hot weather periods, it is common to find dry and cracked earth without even a single shed of water or wet areas. During the period of extended water shortage, atmospheric, surface and ground water can reduce substantially or dry up altogether. Project Need and OverviewDrought poses a serious threat to the resilience of human communities and ecosystems in the United States (Easterling and others, 2000). Water is essential to all life on Earth and a shortage of this vital resource in the environment is bound to negatively affect all forms of life. Low yields equal loss of substantial income. Where in the Nation are droughts or very low flows occurring now? At its most basic level, drought conditions make it difficult to grow crops and sustain livestock. They can just insert a hollow drill into the trunk and pull out a cylindrical sample with the rings included. A drought is a period of drier-than-normal conditions that results in water-related problems. A long-drawn-out period without rainfall can cause an area to dry out. A drought can further cause damage by increasing the risk of large-scale wildfires, and can cause populations to begin tapping into their emergency reserves of water—the aquifers that collect water underground. These toxins can become airborne and have been associated with lung irritation, which can lead to adverse health effects in certain populations. Ostroff, A.C., Muhlfeld, C.C., Lambert, P.M., Booth, N.L., Carter, S.L., Stoker, J.M., and Focazio, M.J., 2017, USGS integrated drought science: U.S. Geological Survey Circular 1430, 24 p., https://doi.org/10.3133/cir1430. Drought has left the West parched and thirsty. The “new normal” of water management across the United States suggests we need to consider the regions we live in are either heading into a drought or coming out of a drought. Trees and vegetation cover are essential for the water cycle as it helps to limit evaporation, stores water, and attracts rainfall. However, over a period of many years, the average amount of precipitation in a region is fairly consistent. A 2011 drought in Texas caused $26 million in pavement distress. On this basis, extended deficiency of water can affect the society in various ways both directly and indirectly. Some regions are routinely wet and others are routinely dry. Key events like. Drought reduces the size of water bodies and causes them to become stagnant. (And Can They Choke on Raisins), Can Squirrels Eat Popcorn? In the deserts of the Southwest, the average precipitation is less than 3 inches per year. Sonia Madaan is a writer and founding editor of science education blog EarthEclipse. Businesses at times have to use fuel-powered generators which result in higher business operation costs. Common cases of hunger, anemia, malnutrition, and mortalities are recorded in poorer nations.
