Essay on Drought for Students and Children

500+ words essay on drought.

Drought is a dangerous condition which decreases the quality of life. It is termed as a natural disaster with harmful effects. A drought usually occurs when a region faces a shortage of water. This is mainly due to lesser rainfalls. In addition, droughts have proven to be fatal for mankind and wildlife as well.

Moreover, drought is the most dangerous for a farmer. As they do not have an ample supply of water, their crops dry out. This becomes a reason for worry as it is their sole income. Furthermore, drought also leads to various other problems for the environment and mankind.

Causes of Drought

Drought is caused due to various reasons. One of the main reasons is deforestation . When there will be no trees, the water on land will evaporate at a faster rate. Similarly, it lessens the soil capacity to hold water resulting in evaporation. Moreover, lesser trees also mean lesser rainfall which eventually leads to drought.

Furthermore, as the climate is changing, the water bodies are drying up. This results in a lower flow of surface water. Therefore, when the rivers and lakes will dry out, how will the people get water? In addition, global warming is a major cause of this. The greenhouse gas emitted causes the earth’s temperature to rise. Thus, it results in higher evaporation rates.

Subsequently, excessive irrigation is also a great cause of droughts. When we use water irresponsibly, the surface water dries up. As it does not get ample time to replenish, it causes drought.

Impact of Drought

Drought is a serious disaster which impacts the whole of mankind, wildlife, and vegetation greatly. Moreover, a region which experiences drought requires a lot of time to recover from the disaster. It is a severe condition which interferes with the quality and functioning of life.

Most importantly, the agriculture sector suffers the most at the hands of drought. For instance, farmers face a loss of crop production, livestock production. Moreover, they experience plant disease and wind erosion. Similarly, they also have to face heavy financial losses. Their financial condition worsens and they end up in debt. This also leads to higher rates of depression and suicides.

Furthermore, wildlife also suffers. They do not get sources of water to drink from. In addition, when forest fires happen due to droughts, they also lose their habitats and life. Just like any natural disaster , droughts also result in inflation of prices. The basic products become expensive. The poor people do not get access to essential foods due to high rates. Subsequently, droughts also degrade the quality of the soil. This result in poor or no yielding of crops.

In short, drought is definitely one of the most catastrophic natural disasters. It causes loss of life, vegetation and gives rise to other deadly problems like famine. The citizens and government must join hands to prevent droughts to save thousands of lives. This joint effort can help save the world from such a catastrophe.

Understanding Droughts

Drought is an extended period of unusually dry weather when there is not enough rain.

Loading ...

Drought  is an extended period of unusually dry  weather  when there is not enough rain. The lack of  precipitation  can cause a variety of problems for local communities, including damage to  crops and a shortage of drinking water. These effects can lead to devastating  economic  and social disasters, such as  famine ,  forced migration  away from drought -stricken areas, and  conflict  over remaining  resources .

Because the full effects of a drought can develop slowly over time, impacts can be underestimated. However, drought can have  drastic  and long-term effects on  vegetation , animals, and people. Since 1900, more than 11 million people have died and more than 2 billion people have been affected by drought . Drought is also one of the costliest weather -related disasters. Since 2014 California has lost at least 2 billion-dollars a year, due to drought .

Defining Drought

Drought is a complicated  phenomenon , and can be hard to define. One difficulty is that drought means different things in different regions. A drought is defined depending on the average amount of precipitation that an area is accustomed to receiving.

For example, in Atlanta, Georgia, the average rainfall is about 127 centimeters (50 inches) a year. If  significantly less rain falls, there may be water shortages and a drought may be declared. However, some arid regions, such as the  deserts of the American Southwest, may receive less than about 25 centimeters (10 inches) of rainfall in a non- drought year. A drought in Atlanta could be a very wet period in Phoenix, Arizona!

Determining the start of a drought can be tricky. Unlike many  natural hazards that bring about sudden and dramatic results—such as  earthquakes ,  tornadoes , and  hurricanes —the onset of a drought can be gradual and subtle. It can take weeks, months, or even years for the full effects of long-term  inadequate  rainfall to become apparent.

The end of a drought can also be difficult to determine. While a single rain storm will provide short-term relief from a drought , it might take weeks or months before levels of precipitation return to normal. The start and end of a drought are often only clear in hindsight .

Causes of Drought

Most droughts occur when regular weather patterns are interrupted, causing  disruption to the  water cycle . Changes in  atmospheric circulation  patterns can cause storm tracks to be  stalled for months or years. This disruption can dramatically impact amounts of precipitation that a region normally receives. Changes in wind patterns can also be disruptive to how moisture is absorbed in various regions.

Scientists have found a link between certain  climate  patterns and drought . El Niño is a weather event where the surface water in the Pacific Ocean along the central South American coast rises in temperature. These warmer waters alter storm patterns and are associated with droughts in Indonesia, Australia, and northeastern South America. El Nino events keep climate scientists guessing, by occurring every two to seven years.

La Niña is the counterpart to El Niño , when the surface water in the Pacific Ocean along the coast of South America decreases in temperature. The cooler waters affect storm patterns by contributing to drier-than-normal conditions in parts of North and South America. El Niño and La Niña both usually last about a year. The effects of La Niña on weather patterns are often more  complex  than El Niño . Two of the most devastating droughts in the history of the United States—the 1930s  Dust Bowl  and the 1988 drought in the Midwest—are associated with the effects of La Niña.

There is still a lot of debate about the connection between drought and  global warming , the current period of  climate change . A 2013 NASA study predicts warmer worldwide temperatures will mean increased rainfall in some parts of the world and decreased rainfall in others, leading to both more flooding and more droughts worldwide. Other scientists question the prediction that there will be more droughts and believe global warming will create a wetter climate around the world.

Impacts of Drought

Trees and other plants have adapted to withstand the effects of drought through various survival methods. Some plants (such as grasses) will slow their growth or turn brown to conserve water. Trees can drop their leaves earlier in the season to prevent losing water through the leaf surface. However, if drought conditions persist, much vegetation will die.

Certain plants have adapted so they can withstand long periods without water. Yuccas, for instance, have deep  root systems that can seek out water with incredible efficiency. Cacti have spiny, hairy spines, spikes, or leaves that limit how much water they lose to  evaporation . Mosses can withstand complete  dehydration . Juniper trees can self- prune  by steering water only to ward the branches required for survival. Other plants only grow when there is enough water to support them. In periods of drought , their seeds can survive under the  soil for years until conditions are favorable again.

However, many organisms cannot adapt to drought conditions, and the environmental effects of extended, unusual periods of low precipitation can be  severe . Negative impacts include damage to  habitats , loss of  biodiversity , soil   erosion , and an increased risk from  wildfires . During the U.S. drought of 1988, rainfall in many states was 50 to 85 percent below normal. Summer thunderstorms produced  lightning  without rain and  ignited fires in dry trees. In Yellowstone National Park 36 percent of the park was destroyed by fire.

Drought can also create significant economic and social problems. The lack of rain can result in crop loss, a decrease in land prices, and  unemployment  due to declines in production. As water levels in rivers and lakes fall, water-supply problems can develop. These can bring about other social problems. Many of these problems are health-related, such as lack of water, poor  nutrition , and famine . Other problems include conflicts over water usage and food, and forced migration away from drought -stricken areas.

While drought is a naturally occurring part of the weather cycle and cannot be prevented, human activity can influence the effects that drought has on a region. Many modern agricultural practices may make land more  vulnerable to drought . While new  irrigation  techniques have increased the amount of land that can be used for farming, they have also increased  farmers ’ dependence on water.

Traditional agricultural techniques allow land to “rest” by rotating crops each season and alternating areas where  livestock graze . Now, with many areas in the world struggling with overpopulation and a shortage of farmland, there is often not enough  arable  land to support  sustainable practices. Over-farming and  overgrazing  can lead to soil being  compacted and unable to hold water. As the soil becomes drier, it is vulnerable to erosion . This process can lead to  fertile  land becoming desert -like, a process known as  desertification . The desertification of the  Sahel  in North Africa is partly blamed on a prolonged drought whose effects were intensified by farming practices that result in overgrazing .

Increased drought conditions in Kenya have been attributed to  deforestation and other human activities. Trees help bring precipitation into the ground and prevent soil erosion . But in 2009, it was reported that one-quarter of a protected forest reserve had been cleared for farming and  logging , leading to drought conditions affecting 10 million people around the country.

Historical Droughts

Scientists often study historical droughts to put modern-day droughts in perspective. Since our  data  from  thermometers and  rain gauges only goes back about 100 to 150 years, scientists must research  paleoclimatology , the study of the atmosphere of prehistoric Earth. Scientists gather paleoclimatic data from  tree rings ,  sediments found in lakes and oceans,  ice cores , and archaeological  features and  artifacts . This allows scientists to extend their understanding of weather patterns for millions of years in the past.

Analyzing paleoclimatic data shows that severe and extended droughts are an  inevitable  part of natural climate cycles. North America has experienced a number of long-lasting droughts with significant effects. It is thought that droughts brought about the decline of the  Ancestral Puebloans  in the Southwest during the 13th century, and the central and Lower  Mississippian societies in the 14th to 16th centuries.

In South America, massive migration out of the once-fertile Atacama Desert 9,500 years ago can be explained by the onset of extreme drought.

In Africa, the Sahel region experienced a dry period from 1400 to 1750 that radically altered the  landscape . The water level in Lake Bosumtwi, Ghana, for instance, fell so low that an entire forest grew on the lake’s edges. Today, visitors can still see the tops of trees growing out of the lake—where the water is now more than 15 meters (50 feet) deep.

What scientists have learned by looking at Earth’s drought history is that periods of severe drought are a regular part of nature’s cycle. As devastating as droughts in the last century have been, they are considered relatively minor compared to the severity of earlier droughts that have lasted more than a century.

Major Droughts in the Past Century

The Dust Bowl of the 1930s is probably the most well-known drought experienced by the U.S. By 1934, 80 percent of the U.S. was struggling with moderate-to- severe drought conditions. The drought lasted nearly a decade and had devastating effects on crop production in the  Great Plains . The combination of lack of rain, high temperatures, and strong winds affected at least 50 million acres of land. Massive clouds of dust and sand formed as unusually strong winds lifted the dry soil into the air. These clouds could block out the sun for days, giving the period the name “ dust bowl .” In 1934, one dust cloud infamously traveled 2,414 kilometers (1,500 miles), from the Great Plains to the eastern U.S.

Mass migration was an indirect effect of the Dust Bowl . Farmers and their families were forced to migrate to other areas in search of work, and by 1940, 2.5 million people had fled the Great Plains . Of those, 200,000 moved to California. The influx of migrants into existing economies already strained by the Great Depression led to a rise in conflict , unemployment , and  poverty .

In the 1950s, severe drought returned to the Great Plains and southwestern United States, affecting half of the continental U.S. Low rainfall and high temperatures caused the production of crops in some areas to drop nearly 50 percent. Hay became too expensive for ranchers, and they had to feed their cattle prickly pear cactus and molasses to keep them alive. By the end of the five-year drought in 1957, 244 of Texas’ 254 counties had been declared  federal   drought disaster areas .

In the late 1980s, the U.S. experienced one of the costliest drought in its history. The three-year spell of high temperatures and low rainfall ruined roughly $15 billion of crops in the  Corn Belt . The total of all the losses in energy, water,  ecosystems , and  agriculture  is estimated at $39 billion. Federal assistance programs were able to help many farmers , but a longer-lasting drought would make it more difficult for the government to provide nationwide aid.

Droughts continue to affect the U.S. Texas has been suffering from drought since 2010, with 2011 ranking as the driest year in the state’s history. A September 2012  National Geographic  magazine article called Texas “The New Dust Bowl.” By 2013, 99 percent of the state was dealing with drought.

Australia is also a frequent victim of drought . The last decade has been especially severe , earning it the name The Big Dry or The Millennium Drought . Much of the country was placed under water restrictions, wildfires spread in the dry weather , and the water level in some  dams fell to 25 percent. In 2007, 65 percent of viable land in Australia was declared to be in a drought . The drought was officially declared over in April 2012.

Droughts that occur in the  developing world  can cause even greater devastation. The Sahel region in Africa, which includes eight countries, endured a series of droughts in the 1970s and 1980s where annual rainfall dropped by about 40 percent. In the early 1970s, more than 100,000 people died and millions of people were forced to migrate. Conditions continue to be critical in the area due to drought , overpopulation, failing crops , and high food prices. Drought emergencies for the region have been declared four times since 2000.

The  Horn of Africa , which includes the countries of Ethiopia, Somalia, Eritrea, and Djibouti, is particularly vulnerable to droughts . Because almost 80 percent of the population is rural and depends on agriculture for food and income, famine often accompanies drought .

Struggles for the region’s limited, remaining resources can lead to conflict and war. In 1984 and 1985, the Horn of Africa suffered one of the worst droughts of the 20th century. The U.N. estimates that in Ethiopia alone, 1 million people died, 1.5 million livestock died, and 8.7 million people were affected by the drought—including being hospitalized, forced to migrate, or forced to change professions. In Sudan, 1 million people died, at least 7 million livestock died, and 7.8 million people were affected.

The cycle of drought-famine-conflict has persisted in the region, with drought conditions returning every few years since 2000. In 2006, drought affected 11 million people across the Horn of Africa, and the resulting crisis killed between 50,000 and 100,000 people and affected more than 13 million.

Forecasting and Measuring Drought

Even though scientists are unable to predict how long a drought will last or how severe it will be, early warning systems and  monitoring tools can  minimize  some of drought ’s damaging impacts. There are a number of tools used to monitor drought across the U.S. Due to the limitations of each system, data from different sources are often compiled to create a more comprehensive  forecast .

The Palmer Drought Severity Index (PDSI), developed in 1965 by the  National Weather Service , is the most commonly used drought monitor . It is a complex measurement system and an effective way to forecast long-term drought . Its limitations are that it does not provide early warnings for drought and is not as accurate for use in mountainous areas because it does not account for snow (only rain) as precipitation . The PDSI is often used by the U.S. Department of Agriculture to determine when to begin providing drought relief.

Information from the Standardized Precipitation Index (SPI) is often used to supplement the PDSI data . The SPI, developed in 1993, is less complex than the PDSI and only measures precipitation —not evaporation or water  runoff . Many scientists prefer using the SPI because the time period being analyzed can easily be  customized . The SPI can also identify droughts many months earlier than the PDSI. The National Drought Mitigation Center uses the SPI to monitor drought conditions around the U.S.

The U.S. Drought Monitor , started in 1999, is a joint effort between three U.S. government agencies—the Department of Agriculture , the Department of Commerce, and the National Oceanic and Atmospheric Administration (NOAA). The Monitor   synthesizes data from  academic  and federal scientists into a weekly map indicating levels of dryness around the country. It is designed to be a blend of science and art that can be used as a general summary of drought conditions around the country. It is not meant to be used as a drought predictor or for detailed information about specific areas.

The Famine Early Warning System Network (FEWS NET) monitors satellite data of crops and rainfall across Africa and some parts of Central America, the Middle East , and Central Asia. Analysis of the data allows for early intervention to try to prevent drought -induced famine .

Preparing for Drought

People and governments need to adopt new practices and policies to prepare as much as possible for inevitable future droughts . Emergency spending once a crisis has begun is less effective than money spent in preparation. The  Federal Emergency Management Agency (FEMA)  estimates that every $1 spent in planning for a natural hazard will save $4 in the long term.

Many areas are extremely vulnerable to drought as people continue to be dependent on a steady supply of water. The U.S. Department of Agriculture recommends a series of  conservation  practices to help farmers prepare for drought . Some preventative measures include in stalling an  efficient   irrigation system that reduces the amount of water lost to evaporation , storing water in ditches along fields, regularly monitoring soil moisture, planting crops that are more drought -resistant, and rotating crops to allow water in the soil to increase.

In  urban areas , many cities are promoting water conservation by addressing water usage habits. Some enforce water restrictions, such as limiting days when lawns and plants can be watered, and offering free high-efficiency toilets and kitchen faucets.

Some drought-ravaged cities are taking even more extreme measures to prepare for future droughts. In Australia, the city of Perth is planning for a massive wastewater -recycling program that will eventually provide up to a quarter of the city’s water demands by 2060. Perth has been dealing with a decline in rainfall since the mid 1970s. The city, which is on the edge of a huge desert, is also struggling with its history of over-consumption of water. Water-hungry traditions such as planting large, lush lawns and parks will need to be addressed through conservation measures.

Drought in the USA In August 2012, drought conditions extended over 70 percent of the United States. Counties in 33 states were designated “disaster counties” by the government. In the beginning of 2013, drought still affected more than 60 percent of the country.

Dust Bowl John Steinbeck’s 1939 novel The Grapes of Wrath describes the Dust Bowl drought of the 1930s: “Every moving thing lifted the dust into the air: a walking man lifted a thin layer as high as his waist, and a wagon lifted the dust as high as the fence tops, and an automobile boiled a cloud behind it. The dust was long in setting back again.”

Yunnan Drought

The ongoing drought in Yunnan Province, China, has forced some families to transport water from more than 10 kilometers (6 miles) away.

Essay on Drought for Students and Children | PDF Download

Essay on Drought for Students and Children – Types, Causes, Prevention Steps: Drought is one of both human and natural made disasters. The main cause to occur drought is the human activities around the area’s environmental conditions. The more damage to the environment the more is the chance of rising to droughts. All the living beings will suffer heavily and even to death due to droughts as similarly, the major part is by human beings. Droughts are a disaster that human beings can’t fight against and only nature has the power to abolish it. Droughts have the power to decide whether there is a need for the existence of living beings are not. Similarly, the essay on drought will contain its types, causes, prevention steps to remove, and much more information.

Short Essay on Drought

Drought is one of the dangerous environmental conditions which damages the quality of life on Earth. It exposes the harmful effect and even it is considered a natural disaster. Drought will usually occur when there is a shortage of any of the essential natural resources in a particular area. These droughts are majorly affecting mankind and all other living beings on the earth. Some countries face drought conditions heavily, due to improper environmental balances. Drought will usually arise with the damage of the nature around the area which leads to hotter climatic conditions and fewer rainfalls. The drought was further divided into three types depending on the shortage of essential natural resources. It damages agricultural cultivation and heavy damage to the lives of farmers. Drought brings up the scarcity of water, food, moisture in the air, and high temperature. Initially, it removes the moisture level from the surroundings, and later on, it eliminates the resources.

Causes to occur droughts are deforestation and a rise in temperatures. As trees are removed it leads to an increase in temperature and ecological imbalances in the areas. As the environment was imbalanced it rises to decrease the rainfalls and hot climatic conditions. Global Warming has the part to bring Drought to the environment. On the other side impact of the drought will be high on living beings on earth. It can abolish food, water and tends to hard financial condition to the people and the country. However, there are some prevention steps like reforestation, using solar energy, and many more to reduce the hot climates and to improve the climate conditions. These steps bring up the rains and necessary moisture conditions for the sustainment of humans and living beings.

Long Essay on Droughts

Drought is a dangerous condition in nature where the scarcity of essential natural resources arises. These conditions are harmful to live beings and mankind where they can lead to death. Drought is nothing but the scarcity of water, food, which are due to climatic conditions. As the lesser rainfalls are seen in the areas which cause the droughts and chance to end of living beings. An example of a drought is the deserts where scarcity arises due to high temperature and less moisture climatic conditions. With increasing global pollution and global warming levels, drought will arise easily.

Types of Droughts

Droughts are further divided into four types namely Meteorological, Hydrological, Agricultural, and Socioeconomic. These all are happening due to the dry weather conditions that dominate in particular areas. As the drought arises it brings up the economical and environmental imbalances in the country or a particular area. There are some areas where the lesser rainfall and humid climatic conditions, there is a chance of observing droughts at a higher rate. People of these specific areas will face problems in their daily routine. Scarcity of essential resources is always present in the area and conditions of people are hard and move to a far distance to get resources.

Metrological drought is the scarcity of cool weather or the continuous dry weather located in a particular area. Hydrological drought happens in areas with less water supply and a decrease in the level of water bodies in the areas. Hydrological droughts occurred after the period of the metrological droughts are observed in the unique area. Agricultural Droughts happen when the crops are affected for any reason. Whereas Socioeconomic drought is observed when the demand and supply ratio of goods is unbalanced.

Causes of Droughts

The causes of droughts are many due to man-made activities and very limited natural activities. But the cause of damage for the droughts are due to humans at a higher rate and these are done every day. Whereas natural disaster occurs once and expose heavy damage. Natural activities like rising in temperature, orbital rotation of the earth, moisture levels in the atmosphere, and many others. Human activities like deforestation, global warming activities, etc. There are some other causes like air circulation, water availability, and some ecological imbalances.

The impact of the drought will be at a higher rate where the life span of human beings will decrease. drought will cut all the chains that are present in the ecosystem. All the living beings and nature will be impacted to a further extent which can remove everything on Planet Earth. However, some solution steps need to follow by human beings to the remove roots of droughts. Reforestation and planting of trees bring up the climatic changes in the environment and make fall the rains. These will develop greenness and remove all the pollution even. Every prevention step needs to follow for the removal of drought from the ecosystem.

Droughts are occurring due to various activities that are involved by human beings. Humans have the intelligence to change the environment in a good path and parallel fulfill their needs of them. Every individual in the ecosystem should feel responsible to follow the prevention steps for the improvement of nature for further decades. Everything is in the hands of human beings because there was the chance to reconstruct the issues less environment and healthy ecosystem.

Conclusion: We believe that the above essay on droughts contains all the information and more useful points to get awareness. These essays will helpful for UPSC aspirants and at competitions & exams for students.
