What are the effect of drought?
Drought can also cause long-term public health problems, including: Shortages of drinking water and poor quality drinking water . Impacts on air quality, sanitation and hygiene, and food and nutrition. More disease, such as West Nile Virus carried by mosquitoes breeding in stagnant water.
How does drought affect economy and environment?

How do droughts affect the community?
Examples of drought impacts on society include anxiety or depression about economic losses , conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life. Drought conditions can also provide a substantial increase in wildfire risk.
What are 5 causes of drought?
- 1) Land and water temperatures cause drought. ...
- 2) Air circulation and weather patterns also cause drought. ...
- 3) Soil moisture levels also contribute to drought. ...
- 4) Drought can also be a supply and demand of water issue.
What is drought and its causes and effects?
A drought is caused by drier than normal conditions that can eventually lead to water supply problems . Really hot temperatures can make a drought worse by evaporating moisture from the soil. ... A drought is a prolonged period with less-than-average amounts of rain or snow in a particular region.
What are the causes and consequences of droughts and desertification?
The resultant effects of drought are exacerbated by human activities such as deforestation , overgrazing and poor cropping methods, which reduce water retention of the soil, and improper soil conservation techniques, which lead to soil degradation.
What areas in Australia are most affected by droughts?
Practically the whole of Australia was affected but most persistently the coast of Queensland, inland areas of New South Wales, South Australia, and central Australia . This was probably Australia’s worst drought to date in terms of severity and area.
What are the long term effects of drought?
In long-term drought, native plants may die back, allowing for the intrusion of invasive plant species. Invasive plants may further disrupt the balance of an ecosystem, which can cause further conversion of vegetation, increase wildfire risk, and lead to desertification.
How can we prevent droughts?
- Check your well pump periodically. ...
- Plant native and/or drought-tolerant grasses, ground covers, shrubs, and trees, or small plants. ...
- Install irrigation devices that are the most water efficient for each use, such as micro and drip irrigation, and soaker hoses.
- Use mulch to retain moisture in the soil.
Drought can also affect people’s health and safety. Examples of drought impacts on society include anxiety or depression about economic losses , conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life.
How can the impact of drought be reduced?
Cover Crops – Planting or maintaining vegetation, living or dead , will provide cover on the soil surface and reduce erosion. Low-water using plants like barley are typically used as cover crops during droughts.
What is the main cause of drought?
Droughts are caused by low precipitation over an extended period of time . Atmospheric conditions such as climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape are all factors that contribute to drought.
Does climate change cause drought?
However, regional climate isn’t the only culprit in drought activity. Climate change, namely rising average temperatures driven by human-generated emissions of heat-trapping greenhouse gases , is contributing to droughts, too.
How do humans cause drought?
Widespread cutting down of trees for fuel – This reduces the soil’s ability to hold water – drying out the ground, triggering desertification and leading to drought. Constructing a dam on a large river – This may help provide electricity and water to irrigate farmland near the reservoir.
