Where does desertification occur in Africa?

More specifically, desertification plays its largest role in the grasslands of East Africa, the Kalahari Desert and the Sahara Desert. These regions span over 65 percent of the land. In Ethiopia, 80 percent of the land is at risk of desertification.

What countries in Africa are affected by desertification?

This situation is acute in Somalia, Ethiopia, Djibouti and Kenya, where the combination of weak governments and a lack of annual rains linked to climate change are driving desertification levels.

Where is the desertification most likely to occur?

Africa is the continent most affected by desertification, and one of the most obvious natural borders on the landmass is the southern edge of the Sahara desert. The countries that lie on the edge of the Sahara are among the poorest in the world, and they are subject to periodic droughts that devastate their peoples.

How has desertification affected parts of Africa?

Desertification affects about 46 percent of Africa. … Agriculture in Africa tends to result in low productivity, as most of the land is characterized as a semi-desert. Clearing the land of trees also reduces the structure of the soil. Coupled with wind erosion, the topsoil blows away and leaves a desert-like land.

What places have desertification?

A recently published JRC study identified the following geographic regions as prone to desertification: north-eastern Brazil, south-western Argentina, the southern Sahel, Zambia and Zimbabwe, Sub-Himalayan India, and north-eastern China.

Why is Africa most affected by desertification?

Fire is a primary cause of desertification in the Sahel region of North Africa, where the degradation of drylands is especially pronounced. The degradation of drylands in Africa is forcing people who can no longer make a living off the land to move to urban areas.

What are the main causes of desertification in Africa?

Poverty-related agricultural practices are a major contributor to desertification. Continuous cultivation without adding supplements, overgrazing, lack of soil and water conservation structures, and indiscriminate bushfires aggravate the process of desertification.

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.

How can desertification be prevented?

Preventive actions include:

  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.

How do humans affect desertification?

Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.

How did desertification start in Africa?

Called CLIMBER-2 (for CLIMate and BiosphERe, version 2.1), the model led to the conclusion that the desertification of North Africa began abruptly 5,440 years ago (+/- 30 years). … The change from the mid-Holocene climate to that of today was initiated by changes in the Earth’s orbit and the tilt of Earth’s axis.

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.

What is Africa doing to prevent desertification?

In Africa, FAO supports the expansion of the Great Green Wall initiative, Africa’s flagship programme to combat the effects of climate change and desertification and building resilient landscapes and livelihoods.

Which part of Nigeria is prone to desertification?

It has been estimated that between 50 % and 75 % of Bauchi, Borno, Gombe, Jigawa, Kano, Katsina, Kebbi, Sokoto, Yobe, and Zamfara States in Nigeria are being affected by desertification. These states, with a population of about 27 million people account for about 38 % of the country’s total land area (Table 3.1).

How long has desertification been happening?

Desertification became well known in the 1930’s, when parts of the Great Plains in the United States turned into the “Dust Bowl” as a result of drought and poor practices in farming, although the term itself was not used until almost 1950.

What will happen if desertification continues?

Across the world, desertification affects the livelihoods of millions of people who rely on the benefits that dryland ecosystems can provide. … Some 10 to 20% of drylands are already degraded, and ongoing desertification threatens the world’s poorest populations and the prospects of poverty reduction.
