What are the impact of drought and desertification?

What are the impact of drought and desertification?

If exposed to drought for long periods, they can be affected by desertification, i.e. they can turn into deserts. According to the UNCCD (UN Convention to Combat Desertification), 25% of the world’s land area is either highly degraded or undergoing high rates of degradation.

What are 5 causes of drought?

Here are the 5 natural and human 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 of drought?

When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.

What are the causes and effects of drought?

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 causing moisture to evaporate from the soil. Just because a region is hot and dry doesn’t necessarily mean it is going through a drought.

What is a drought essay?

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.

What is definition of drought?

A drought is defined as “a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area.” -Glossary of Meteorology (1959). Hydrological-occurs when surface and subsurface water supplies are below normal.

What are the precautions of drought?

Precautions to be taken during droughts are:

• Never pour down used water in drain. Use it to water the plants.
• Replace dripping faucets by replacing washers.
• Check all plumbing for leakages and get the faulty repaired by plumber.
• Take a bath by bucket rather than by shower.
• Use mulch to retain water in the soil.

What is the conclusion of desertification?

Desertification is the persistent degradation of dryland ecosystems. It affects the livelihoods of millions of people. In 2000, drylands, which occupy 41% of Earth’s land area, were home to a third of the human population.

What is the conclusion of drought and desertification?

Main conclusions of the review include: drought and desertification continue to threaten the livelihoods of millions of people in Africa. This trend is set to worsen with the onset of climate change, to which many countries in the region are most vulnerable.

How can we prevent drought and desertification?

6.2 What actions can be taken to prevent desertification?

1. Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation.
2. Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.

What are the effects of drought?

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.

What are the causes and consequences of drought and desertification?

2.1 Causes of drought 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 is drought introduction?

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. A drought may last for weeks, months, or even years.
