Water is a vital resource used in everyday life for consumption, irrigation, and hygiene. However, there is times were a state is plagued by drought. A drought is a prolonged period of abnormally low rainfall. Based on California's massive drought and the horrible effects like shortages of water, less food production, and dangerous wildfires ; people on earth need to understand the effects and causes of a drought and learn to be better consumers of water. The USGS (United States Geological Survey) defines a drought as a period of drier-than-normal conditions that results in water-related problems. Currently, the state of California is experiencing a massive drought, facing the fourth year of its worst drought ever, with nearly 70 percent …show more content…
Declines in surface water (lakes, streams, rivers, or reservoirs) flows can be detrimental to hydropower production, navigation, and recreation. USGS states that “streamflows have been below all-time record lows for specific days of the year”. This means that water above the surface are lower than ever causing the availability of surface water to be scarce. Surface water is also measured as annual runoff which include the amount of rain, snowmelt, or evaporation from land. It supplies most of our water needs. With less surface water being available because of the drought, the choice of obtaining water from lakes or streams will slowly deplenish. Groundwater is similar to surface water, but groundwater which is found in aquifers below the surface of hte earth, is one of the state's most important natural resources. Groundwater provides drinking water for a large amount of California's population, supplies business and industries, and is used for irrigation. During a drought if a well is pumped at a faster rate than an aquifer is recharged by rain or other underground flow, water levels will decline. The long term effects can occur after five or more years of severe drought. According to USGS also states that, a long term effect is Land subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth's surface. Overpumping of
The California water drought has been declared a crisis by the governor of California. 2013 was the driest year on record, and California could be running out of water. Californians should be water wise, and their use, or no use, of water will have an enormous impact on this drought. They can use the techniques published in a recent Time article called, 5 Ways to Bust California’s Drought, to reduce their water use. Landscape techniques, alternate water sources, and the personal conservation of water can reduce the use of water, and can have a positive change on this water crisis.
...y. The water in Lake Oroville only reached 39 percent of capacity. That means that California is receiving less than half of their normal rainfall in just the northern region alone. Governor Jerry Brown finally decided to step in and declare the state of California, a drought. The dam isn’t being used nearly to its capacity, causing trouble for the rest of California (Chiocer).
On the heart (center) of California is a flat area with miles and miles of farms and up to 230 different crops. The central valley agriculture is essential to the United States; it not only delivers almost half of the produce but also helps the economy by also giving more job opportunities (California Department of food and agriculture, 2014). Many families depend on the central valley agriculture to survive economically in the United States. It is a well-known fact that rain and snows in the Sierra Nevada Mountains are a very important element in the central valley. No rain in the central valley can cause many devastating issues to occur quickly. Recently in the year of 2013 California received less rainfall than years before. The small amount of water the central valley is receiving is harming not only to the land but humans and animals as well. It’s destroying the habitats of animals with forest fires caused from the dry spells occurring. The central valley is going through a drought, so much that around this time of year the central valley usually accumulates enough rain for the necessities in the valley, agriculture for example. This year, however, has been different, the central valley hasn’t received enough water and this has caused a drought in the valley. Water is an important element in this world for not only human life, but for the environment in general, a shortage of water supply can bring issues to the environment and those living in it. The central valley holds the largest percent of class one soil, not only that, the valley grows a third of all the produce being grown in the United States, that’s more than 230 crops that are being grown in the central valley. However, this drought isn’t only affecting the resident...
Rain rot is a severe skin infection in horses, but it is actually a normal inhabitant of the skin on horses. So why does this disease seem to be so serious? Although it lives naturally in the horses skin, rain rot can get very serious if it gets persistently damaged or wet. This can cause an infection to occur. Rain rot is also called rain scald or dermatophilosis. It is caused by dermatophilus congolensis. Dermatophilus congolensis is a gram-positive bacterium and is the etiologic agent of rain rot. It lives within the skin until the skin is disturbed some how. “The bacteria live in the outer layer of the skin and cause from pinpoint to large, crusty scabs.” (Mendell, 2014, January 29.) It can happen when there is high humidity, wetness for a log period of time, high temperature, or even attacks by biting insects. An increase in the number of biting insects can occur if there is high humidity or warm temperatures so it is best to have a cooling spot for the horses. The biting insects are how this disease can spread from horse to horse. Although there is a natural immunity, some horses are more susceptible to it and can get it year after year. Their must be an infected carrier, or even a fomite like a saddle or a blanket that has the organism in the form of a spore. The spores then have to come in contact with the susceptible animal. Once these spores attach, you can start to see the disease take over the horses body.
For example, then, drought is difficult to define in modern standards, it is typically classified as a shortage of water, usually associated with a deficit of rainfall. That is, drought occurs when the demand or use for water exceeds the current supply of water. It follows, then, the Colorado river drought does not solely affect one area, it’s grandeur has affected the whole southwestern United States. Additionally, the Colorado River Basin Water Management: Evaluating and Adjusting to Hydroclimatic provides information on the meager volume of rain fall. In theory, then, combined with increased temperatures from global warming, and a deficient of rainfall both circumstances have had a descending effect on most surrounding
Second, long term and short term climate changes (e.g. global warming and El Nino) may lead to dryness. Global warming rises
The another devastating abiotic stress which is considered to be highly responsible worldwide for decreasing yield and quality of crop productivity is drought (Lambers et al. 2008 ; Moghadam et al .,2011; Mohsen Pourgholam et al.,2013 ; M. Farooq et al., 2012; Abolhasani and Saeidi, 2004 ; Monjezi et al., 2013).It harms plant growth and development and reduces crop growth rate and also affects biomass accumulation. Generally, in crop plants drought severely affects the cell division and expansion, elongation of root, leaf size, proliferation of root and inhibition of shoot growth (Sharp & Davies 1989; Spollen et al.,1993;Yamaguchi et al.,2010). Furthermore ,it also badly hampers all kinds of plant functions and physiological and biochemical traits such as mineral elements, carbohydrates, free radicals, ions, hormones, lipids, and nucleic acids (HongBo et al., 2005; Yasar et al., ; Moghadam et al .,2011,Mohsen Pourgholam et al,2013) .The transportation of nutrients from the roots to the stem severely get affected by drought as the rate of transpiration is reduced and damage of active transport and membrane permeability take place (Viets, 1972; Alam, 1999; Yasar et al ). Simultaneously, due to decrease in soil moisture, problem occurs with the low distribution of absorbed nutrients by the plant roots in the soil (Alam, 1999; Yasar et al ). More importantly, drought leads to rise in generation of reactive oxygen species (ROS) due to energy accumulation in stress condition of plants (Smirnoff 1993; Asada 2006; Waraich et al.,2011).Drought diminishes photosynthetic carbon fixation primarily through restraining the entrance of CO2 into the leaf or by reducing metabolism (Smirnoff 1993; Loggini et al., 1999; Ap...
For about five years California has experienced above average temperatures and a lack of rain. This lack of rain and snowfall has caused California to become increasingly dry, starting arguments over whose right to water is more important and who needs to be more mindful with their use of water. Farming in California truly began during the gold rush when water was redirected to land where food was grown for those looking for gold (Siegler, 2015). The farmers that have stayed on that land now have senior water rights (“Water wars”, 2015). Farmers that settled their land before 1914 are those with senior water rights (Terrell, 2015). Governor Jerry Brown has called for a cut in water use by one-quarter percent to people living
A drought means there is not enough precipitation. It is a period of unusually dry weather that keeps on long enough to cause environment or economic problems which result in a water shortage and destroy vegetation, animals and crops. Drought can happen even if there is some rainfall. Bushfires and heat waves will occur because of drought. (Francesca.F, 2000)
Zara Beadle METR 113 16 December 2015 Final paper California Drought The California drought has been extremely harmful to the states’ air quality. Since 2012, California has seen the worst drought conditions in 1,200 years and it is severely affecting air quality (California’s drought, 2015). As of 2015, the cities of Hanford, Merced, Modesto, Fresno, Yuba City, Lancaster-Palmdale, Chico, Sacramento, and Bakersfield have experienced exceptional drought coverage (Pestano, 2015).
This is not a problem which is limited to the developing world either, as even the United States has also been experiencing the effects of water shortages in recent years. In the US, the average citizen uses more than three times the amount of water as many European countries (Data 360). A key difference between the US and the European continent is the geographical variation. A majority of the large cities in America where water is becoming more scarce are located in the West and are surrounded by arid landscapes, although it should be noted that shortages are not limited to this area alone (The Atlantic). Most water usage in the country is reserved for irrigation of farmland, general landscaping, and home use (EPA). It is estimated by the EPA that the average family uses over 400 gallons of water every day, and that the cumulative volume of water used in homes is much less than the former two greatest uses. Not only is extreme overuse a problem, but seasonal droughts have become increasingly frequent throughout the US. Here, we will look more closely at the causes, effects, and implications of water shortages across the United States and beyond.
Groundwater remained the main supply until 1971 which was when Las Vegas became more dependent on Colorado River water due to the “Southern Nevada Water System” (Brown, n.d.; Larsen et al., 2015). Since then up to 90,000 acre-feet of groundwater has been pumped on a yearly basis, this value surpasses the natural groundwater recharge (Laczniak et al., n.d.). Rain as well as snow serves as the primary sources of groundwater recharge for the aquifers while precipitation plays a minor role (Laczniak et al., n.d.). Due to there not being balanced discharge and recharge this has led to subsidence and as a result of this subsidence the storage capacity of aquifers has decreased due to compaction (Laczniak et al., n.d.). It is estimated that 187,000 acre feet of storage capacity in the aquifers has been lost due to compaction (Laczniak et
Here are two places in the World that are having big drought problems and are at risk of depleting all of their fresh water due to the excess digging into their aquifers. Waukesha, Wisconsin, USA and Sana’a, the capital of Yemen, which is located in the Middle East; both are the scarcest regions of the world. Both regions are at risk of losing all of their fresh water...
