If you create an account, you can set up a personal learning profile on the site. Can you suggest why a climate which is gradually becoming warmer will result in an increase in the risk of droughts? Hint: think back to Study Session 9.

What causes drought?

Drought and drought impacts are really two sides of the same coin. We cannot fully understand drought without also understanding its impacts, which can affect all parts of our environment and our communities.

Understanding drought conditions, societal vulnerability, and their related effects on one another provide us with historical lessons that can aid in dealing with future drought conditions. Drought does not always offer the same immediate and dramatic visuals associated with events such as hurricanes and tornadoes, but it still has a huge price tag. In fact, droughts rank second in types of phenomena associated with billion-dollar weather disasters during the past three decades.

These costly drought impacts come in a variety of forms. Examples of economic impacts include farmers who lose money because drought destroyed their crops or ranchers who may have to spend more money to feed and water their animals.

Economic impacts can be both direct, such as decreases in dairy production, and indirect, as seen by increases in the price of cheese. In addition to the economy, drought also affects the environment and society.

Plants and animals depend on water, just as people do. Drought can shrink their food supplies and damage their habitats. Sometimes this damage is only temporary, and other times it is irreversible. Drought conditions can also provide a substantial increase in wildfire risk. As plants and trees wither and die from a lack of precipitation, increased insect infestations, and diseases—all of which are associated with drought—they become fuel for wildfires.

Long periods of drought can equate to more wildfires and more intense wildfires, which affect the economy, the environment, and society in many ways such as by destroying neighborhoods, crops, and habitats.. To help decision makers and the public address these issues, the National Integrated Drought Information System provides assessments of drought conditions through systematic categorization and reporting of impacts.

By considering the economic, environmental, and social impacts of drought, scientists can study specific events and their underlying meteorological contributors to improve future societal preparedness. Additionally, the National Weather Forecast Offices produce Drought Information Statements for affected areas, which include information about impacts. And, on the international scale, the U. This is part of a series of articles about monitoring and assessing drought conditions across the United States.

This creates a water shortage that damages crops, livestock, and the environment. Since droughts adversely impact the agricultural industry, those that depend on the commodities from the industry suffer as well. Food becomes more scarce and demand exceeds supply. Prices go up, and the commodities markets waiver. If the economy is already in a state of depression or recession, a drought can increase that state.

5 Causes Of Drought

Drought directly and indirectly affects the entire socio-economic and environmental sectors in southwestern Germany. Such impacts are a result of the drought hazard and an underlying vulnerability of the systems. With respect to climate change and the dynamics of vulnerability over time, it becomes crucial to investigate the preceding components, in order to understand possible future magnitudes of the hazard and drivers of drought impacts. Therefore, drought indices were generated from the early nineteenth century in order to identify exceptional meteorological summer droughts. Documentary evidence and historical yield statistics were used to contextualise historical drought events by drought impacts and responses.

California is in a mega drought and most data indicates water is becoming more available. Georgia is heading into a drought. Ohio, who has been in a sports championship drought and moving out of it is headed into a water drought. As overall temperatures increase more water evaporates and severe weather conditions increase. Landscapes and crops need more water to survive and overall the demand for water increases.

A drought is a prolonged period with less-than-average amounts of rain or snow in a particular region. The severity of the drought depends on the amount of time that a region receives below-average precipitation. This is called a flash drought. A drought is caused by drier than normal conditions that can eventually lead to water supply problems.

DROUGHT: Monitoring Economic, Environmental, and Social Impacts

A drought is an event of prolonged shortages in the water supply, whether atmospheric below-average precipitation , surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour. Drought is a recurring feature of the climate in most parts of the world. However, these regular droughts have become more extreme and more unpredictable due to climate change.

People are forced to shift to other places in search for better living conditions during droughts. Hence, farmers have to spend more money to buy water or drill wells to keep the crops and livestock nourished with enough water. This leads to loss of biodiversity and disruption of the natural ecosystems. Also, lots of water has to be availed for watering the farm animals to ensure the daily water consumption standards are met. Different sets of people have different definitions of drought.
