What is the importance of droughts and desertification in South Africa?

The significance of these problems in the region is demonstrated by outlining the impact that drought and desertification have on economic growth and poverty reduction, agriculture and food security, water, biodiversity, energy and migration.

What are the impact of desertification in South Africa?

South Africa is losing about 300 to 400 million tons of topsoil every year. Areas such as the Northern Cape are especially prone to desertification. To halt desertification the number of animals on the land must be reduced, allowing plants to regrow.

What are the impact 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.

What is the importance of drought to the economy of South Africa?

The drought has led to job losses in the province’s agriculture sector. The 2017 third quarterly labour force survey showed that approximately 25,000 jobs were lost from the agricultural sector nationally. More than 20 000 of these were lost in the Western Cape province. Many were associated with the drought.

What is the importance of desertification?

Vegetation and its diversity are key for soil conservation and for the regulation of surface water and local climate. Desertification also contributes to global climate change by releasing to the atmosphere carbon stored in dryland vegetation and soils.

What are 3 causes of desertification?

Overgrazing is the major cause of desertification worldwide. Other factors that cause desertification include urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind.

What are three effects of desertification?

Higher food prices, water availability, violent conflicts for land, migration, increasing poverty, pollution from wind-blown dust particles coming from distant lands, could be the outcomes of desertification if we let it consume more of our planet.

What are the impacts of drought?

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 the causes and effects of drought?

The soil starts drying out and plants die. When this pattern continues for several weeks, months or years, the flow of streams and rivers decreases and water levels in lakes, reservoirs and wells fall. Eventually, the unusual dry weather causes water supply issues, and the dry period becomes a drought.

What are the main causes of drought in South Africa?

One of the main causes of drought in South Africa is the variability in rainfall (Mason and Tyson, 2000; Tyson and Preston-Whyte, 2000 and Vogel et al., 2000). The El Niño phenomenon accounts for approximately thirty percent of rainfall variability (Tyson and Preston-Whyte, 2000).

How do droughts affect human health?

During drought, there is an increased risk for wildfires and dust storms. Particulate matter suspended in the air from these events can irritate the bronchial passages and lungs. This can make chronic respiratory illnesses worse and increase the risk for respiratory infections like bronchitis and pneumonia.

How the government can reduce the impact of drought in South Africa?

These include: Water storage and transfer developments; Water infrastructure such as dams and conveyance pipelines will be developed to redistribute water over time and space; Review and promulgate restrictions within the legislation to restore and protect ecological infrastructure; and.

Why is desertification a problem?

* Desertification is mainly a problem of sustainable development. Its causes include over-cropping, over-grazing, improper irrigation practices, and deforestation. Poor land management practices such as these often stem from the socioeconomic conditions in which the farmers live, and can be prevented.

How dangerous is desertification?

Trees are an important way to protect farmland. Long dry periods, warmer temperatures and the removal of trees can all lead to the loss of good cropland. … Floods can remove fertile topsoil and begin a process resulting in the loss of planting areas.

How does desertification affect personal?

In particular desertification can increase fe- cal-oral diseases and water-wash diseases, which spread from one person to another due to the lack of water for personal hygiene. The drying of water sources increases the use of heavily polluted water, leading to severe epi- demics.
