Final answer:
The statement is true; the Sahel is highly affected by drought due to its geographical position as a transitional zone between the Sahara and savanna, exacerbated by climate change and limited rainfall.
Step-by-step explanation:
True, the Sahel is one of the areas in Africa that is most affected by drought. The Sahel is a semiarid transition zone located between the Sahara desert to the north and the savanna to the south. This region is characterized by occasional rainfall and sparse vegetation. Because it is a transitional zone, the Sahel experiences significant variations in climate, with longer rainy seasons occurring the farther south you travel. However, it is susceptible to frequent droughts that can have devastating impacts on the local agriculture and food security. As the climate changes, these droughts are becoming more intense, exacerbating the existing challenges faced by the communities that depend on this land for their livelihoods.
Considering the significant decrease in rainfall in the Sahel and other dry regions of Africa, agricultural productivity has plummeted. With most farmers relying on rainfall for crop irrigation and the intensifying effects of climate change, the Sahel has indeed suffered greatly from drought. Countries in the Horn of Africa and regions like the Madagascar Grand Sud have witnessed severe drought conditions leading to food insecurity and the urgent need for humanitarian aid. Additionally, the ecosystem's struggle is underscored by the dependence of nomadic communities, such as the Fulani and the Tuareg, on the limited resources available in this harsh environment.
