Baobab trees growing in the wooded-grassland area of Senegal in West Africa. 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.

In what area is desertification problems the greatest?

Desertification is the process of land turning into desert as the quality of the soil declines over time. Many countries around the world suffer from the problems caused by desertification but it is the Sahel region of Africa where the effects are greatest.

Where does desertification occur in Africa?

Desertification 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.

Which region in Africa is most negatively affected by deforestation?

Deforestation in the Congo Rainforest. Central Africa’s deforestation rate since 1990 has been the lowest of any major forest region in the world. However there are still a number of threats to the health of the Congo rainforest and its residents.

Why is desertification a problem in Africa?

It has been estimated that 319 million hectares of Africa are vulnerable to desertification hazards due to sand movement. … Deforestation exposes the soil to high temperatures which break down the organic matter, increase evaporation and make the soils vulnerable to erosion.

In what part of Africa is the largest rainforest found?

The Congo Basin
The Congo Basin is Africa’s largest contiguous forest and the second-largest tropical rainforest in the world. Covering about 695,000 square miles, this swamp-struck tropical forest covers portions of Cameroon, Central African Republic, Democratic Republic of Congo, Republic of the Congo, Equatorial Guinea and Gabon.

Which areas of Africa are least vulnerable to desertification?

Practically every country of Africa is prone to desertification, but the Sahelian countries at the southern fringe of the Sahara are particularly vulnerable. Only about 19% of Niger is non-desert and of this 17% belongs to high and very high vulnerability classes.

How is Africa affected by deforestation?

As deforestation in Africa increases, less moisture is transpired into the atmosphere resulting in the formation of fewer rain clouds. Leading to less rain and subsequently this decline in rainfall could subject an area to drought.

What are negative effects of deforestation in Africa?

Deforestation has massive effects on the biosphere. It contributes to carbon emissions, changes in water cycles and biodiversity loss. The main cause of deforestation is the conversion of forested lands to agricultural lands.

Why are areas in Africa at risk of drought and desertification?

Inappropriate farming systems such as continuous cultivation without adding any supplements, overgrazing, poor land management practices, lack of soil and water conservation structures, and high incidence of indiscriminate bushfires lead to land degradation and aggravate the process of desertification.

Where is the risk of droughts and desertification is in Africa?

While recurrent droughts are a common feature throughout most of the drylands in Africa, three distinct areas have been identified as most at risk: Mediterranean Africa, the Sudano-Sahelian region and the Kalahari-Namib region in southern Africa.

What are the effects of desertification in Africa?

The degradation of drylands in Africa is forcing people who can no longer make a living off the land to move to urban areas. According to the UN Population Division, the population of Lagos, Nigeria, will grow from 13.4 million in 2000 to 23.2 million in 2015, partly due to an influx of displaced rural communities.

Which provinces are affected by drought in South Africa?

South Africa: Worst in 100 Years – Drought in All Three Cape Provinces Declared a National Disaster. (File photo). The National Disaster Management Centre has declared a drought disaster due to the persistent drought conditions in the Northern Cape, Eastern Cape and Western Cape.

Why is desertification a problem?

Desertification is a global issue, with serious implications worldwide for biodiversity, eco-safety, poverty eradication, socio-economic stability and sustainable development. Drylands are already fragile. As they become degraded, the impact on people, livestock and environment can be devastating.

What is the main cause of deforestation in Africa?

The conversion of forest land to agriculture, both subsistence and commercial, is by far the most common and most destructive cause of deforestation in Africa and other tropical regions.

What trend has caused the greatest increase in deforestation in Africa?

While deforestation in other parts of the world is mainly caused by commercial logging or cattle ranching the leading causes in Africa are associated with human activity. Developing countries rely heavily on wood fuel, the major energy source for cooking and heating.

Where is deforestation happening the most?

95% of global deforestation occurs in the tropics. Brazil and Indonesia alone account for almost half. After long periods of forest clearance in the past, most of today’s richest countries are increasing tree cover through afforestation.

What is the biggest threat to African rainforests today?

Logging and agriculture continue to be two of the biggest threats to Africa’s tropical forests. The unsustainable production of palm oil is one of the biggest drivers.

What poses the greatest threat to the savanna area of Africa?

One of the major threats to the savanna ecosystem is global warming, so one of the main solutions is to decrease our output of greenhouse gasses.

What is the problem with deforestation?

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

What countries in Africa are affected by deforestation?

Between 2000, Burundi has the highest annual deforestation rate in Africa and second largest in the world (Chakravarty et al., 2011) while Sudan has the highest net loss with Nigeria the least among the five countries (although Nigeria has the highest deforestation rate of primary forest in the world). …
