Tips for your answer

Explain that the eastward expansion of the Thar Desert is driven by both natural processes and anthropogenic degradation, particularly the weakening of the Aravalli ecological barrier.
Remember UNCCD, ISRO Desertification and Land Degradation Atlas, National Action Programme to Combat Desertification and the Aravalli Green Wall Project.
Do not equate desertification with the spread of deserts alone. Desertification refers to land degradation that can occur even outside existing desert regions.
