What are the 10 causes of drought?

Lack of rainfall which is likely to cause drought.
Deforestation as a result of cutting down of trees.
Drying out of rivers and lakes.
Global warming.
Weather patterns as well as air circulation.
Depletion of soil moisture level.

What is drought and its effects?

A drought is a

period of time when an area or region experiences below-normal precipitation

. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater, diminished stream flow, crop damage, and a general water shortage. … Droughts affect people in a several ways.

What are the main causes of drought?

A lack of water in stores such as rivers, lakes, reservoirs and aquifers (water stored underground naturally)

can lead to drought. Areas that rely on rainfall and surface water are more likely to experience drought. Surface water quickly evaporates in warm, dry conditions leading to an increased risk of drought.

How can we prevent drought?

Avoiding Overuse

Being mindful of the amount of water you use each day can be a powerful way to prevent droughts.

Turning off the faucet while you brush your teeth

, watering your garden early in the morning so less water evaporates, and installing low-flow plumbing fixtures all are good ways to prevent wasted water.

Does climate change cause drought?

Climate change, namely

rising average temperatures driven

by human-generated emissions of heat-trapping greenhouse gases, is contributing to droughts, too.

How can Droughts affect us?

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 do droughts affect human health?

Health effects associated with drought episodes are principally indirect and include

the increased risk of infectious diseases and diarrheal pathologies, malnutrition, changes in the ecology of vector-borne diseases, cardiorespiratory affectations, serious mental health repercussions and greater risk of mortality

( …

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.

What are the two main 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 are the causes and effects of drought in southern Africa?

Drought in South Africa caused by

El Niño, human action and climate change

. The present drought in Cape Town has been caused by extremely poor rainfall in recent months, with the result that the water supplies are under enormous pressure.

What time of year does a drought occur?

Even if the total amount of rainfall for a year is about average, rainfall shortages can occur during a period when moisture is critically needed for plant growth, such as in the

early summer

. When little or no rain falls, soils can dry out and plants can die.

How does droughts affect humans and animals?

When a drought occurs,

their food supply can shrink and their habitat can be damaged

. … Losses or destruction of fish and wildlife habitat. Lack of food and drinking water for wild animals. Increase in disease in wild animals, because of reduced food and water supplies.

What are the negative effects of drought and desertification?

degradation of the vegetal covering, through to its total disappearance

; dispersion of solid particles in the atmosphere – sand storms, air pollution – with a negative impact on man’s health and productive activities; reduction of farming and breeding production: malnutrition and hunger; migrations of people and wars.

How does desertification cause drought?

Since the 1970s, the Sahel has experienced drought conditions on a regular basis. This is down to physical and human factors:

Overgrazing and deforestation on marginal land

can lead to desertification . With less vegetation there is less transpiration and evaporation from the soil, causing less rainfall.
