What type of environmental issues are affecting the Sahel?

The Sahel is particularly vulnerable to rainfall variability, land degradation, and desertification due to its high dependence on rain-fed agriculture and livestock, according to a study by the UN Environment Program. Climate change is introducing even more unpredictability in water and food availability.

What are the issues in the Sahel?

Armed conflict, economic insecurity, and the adverse effects of climate change are some of the biggest challenges affecting the region. Indiscriminate attacks against civilians and public infrastructure -including schools and health facilities- have threatened the lives of millions of people and their livelihoods.

What is the Sahel and what are the problems currently facing the African region?

It’s called the Sahel, and in the center of it are Burkina Faso, Mali and Niger. These three countries are facing a toxic mix of escalating armed conflict, displacement, hunger and widespread poverty – all compounded by the severe impacts of climate change and COVID-19.

Why is Sahel at risk of climate change?

Climate change is partly to blame. The United Nations estimates that roughly 80% of the Sahel’s farmland is degraded. Temperatures there are rising 1.5 times faster than the global average. As a result, droughts and floods are growing longer and more frequent, undermining food production.

Is Sahel affected by desertification?

The Sahel, or Sahelian Zone, lies south of the Sahara Desert in North Africa. This dry savanna environment is particularly prone to devastating drought years. … Desertification in the Sahel can largely be attributed to greatly increased numbers of humans and their grazing cattle. West Sahel countries appear in yellow.

How have environmental changes in the Sahel affected local communities within the region?

The environmental crisis

Things have gotten worse in recent decades, experts say. Between 1970 and 1993, the region recorded 20 years of severe drought. The frequency and severity of droughts and floods has increased over this period. FAO reports that over 80% of the region’s land is degraded.

How have the traditional occupations of the inhabitants of the Sahel contributed to environmental issues in the region?

How have the traditional occupations of the inhabitants of the Sahel contributed to environmental issues in the region? Animal herding in the region has led to overgrazing and the destruction of soil. Overfishing has destroyed the ecosystems in the region’s lakes and rivers.

What major environmental problem is affecting the Sahel region of Africa?

The Sahel is particularly vulnerable to rainfall variability, land degradation, and desertification due to its high dependence on rain-fed agriculture and livestock, according to a study by the UN Environment Program. Climate change is introducing even more unpredictability in water and food availability.

What is the major problem with the Sahel in Africa?

Climate change remains one of the major challenges that Sahel’s countries face. The UN estimates that 80 percent of the agricultural areas in the Sahel belt are already affected by climate change. In this region the temperature is rising one and a half times as fast as the global average.

Why is there violence in the Sahel?

Populations in the Central Sahel – Burkina Faso, Mali and Niger – face atrocity crimes as a result of attacks by Islamist armed groups and security forces, as well as growing conflict between ethnic militias and community self-defense groups.

Why is the Sahel vulnerable to drought?

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 climate of Sahel?

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.

What are some natural resources in the Sahel?

The region is one of the richest in the world in terms of natural resources, including oil, gold and uranium (UN, 2018, p. 7). However, the Sahel, a semi-arid region, is one of the poorest and most environmentally degraded in the world (USAID, 2017, p. 1).

Which areas are affected by droughts and desertification in the Sahel?

The economies, agriculture, livestock and human populations of much of Mauritania, Mali, Chad, Niger and Burkina Faso (known as Upper Volta during the time of the drought) were severely impacted.

How does deforestation affect desertification?

Trees prevent soil erosion and play a pivotal role in the water cycle by absorbing water in the ground and returning water vapor back to the atmosphere. If trees are removed, the area can become much warmer and drier, which may result in desertification, which is a transformation of once fertile land into desert.

What is the effect of deforestation on rainfall and climate?

Answer: Deforestation causes increases in temperatures and changes in the amount and distribution of rainfall —generally creating a drier climate. These impacts can affect soil moisture, reducing yields in some areas and increasing flooding in others.
