What caused the desertification of the Sahel?

The Sahel is a narrow belt of land which lies immediately to the south of the Sahara Desert and which extends across most of Africa. The main causes of desertification include: Overgrazing – an increasing population results in larger desert areas being farmed. Sheep, cattle and goats are overgrazing the vegetation.

What human factor causes drought in the Sahel?

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.

What is the main environmental challenge in the Sahel?

“Over the last half century,” UNEP notes, “the combined effects of population growth, land degradation (deforestation, continuous cropping and overgrazing), reduced and erratic rainfall, lack of coherent environmental policies and misplaced development priorities, have contributed to transform a large proportion of the

What are 3 causes of 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.

What are the 3 main 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 is Sahel climate?

The climate of the Sahel is arid and hot, with strong seasonal variations in rainfall and temperature. The Sahel receives about 200-600 mm (6-20 in) of rainfall a year, which falls mostly in the May to September monsoon season.

Why do developing countries struggle with droughts?

The causes of droughts are essentially natural, but climate change increases the drought severity, frequency, duration, and spatial extent. The impacts of droughts are also strongly exacerbated by anthropological activities, such as deforestation, overgrazing, soil degradation, and water mismanagement.

The Sahel is home to 125 million people, some of the poorest and most vulnerable on earth, and within the next fifteen years, the population will increase by 60%. This is a region suffering from food insecurity, as well as political instability and uncertainty.

How is Sahel affected by climate change?

In the Sahel, droughts are becoming more and more intense. Temperatures are rising 1.5 times faster than in the rest of the world. But climate change is also causing heavy rains (violent thunderstorms, above-normal rainfall). Two out of three people in the Sahel countries live from agriculture and livestock.

Which countries are in the Sahel?

The Sahel countries —Mauritania, Mali, Niger, Burkina Faso and Chad—face many challenges, including chronic insecurity, rising extremism, a lack of economic prospects, and poor access to education, employment and essential services such as water and electricity.

What is special about the Sahel?

The Sahel has a tropical semi-arid climate (Köppen climate classification BSh). The climate is typically hot, sunny, dry and somewhat windy all year long. The Sahel’s climate is similar to, but less extreme than, the climate of the Sahara desert located just to the north.
