The correct answer is A - Check desert encroachment.
The Sahel region is a transition zone between the Sahara Desert and the savannas to the south, and is vulnerable to desertification.
Shelter belts, also known as windbreaks or green belts, are established in the Sahel region to prevent desertification and sand dune encroachment, reduce soil erosion and degradation,protect crops and livestock from harsh winds and sandstorms, and help maintain soil fertility and biodiversity.
The other options are not the primary purpose of establishing shelter belts:
- Providing wood fuel (B) may be a secondary benefit, but not the main purpose.
- Beautifying the region (C) is not a primary goal, although shelter belts can have aesthetic benefits.
- Breaking the harmattan wind (D) is a benefit, but not the main purpose. The harmattan is a dry, dusty wind that blows from the Sahara during the winter months.
