Key Points at a Glance

  1. 1

    2026 Senior Secondary syllabus scope: this topic belongs under Rajasthan Geography: climatic conditions, natural vegetation, major soils, forest resources, wildlife, sanctuaries and conservation.

  2. 2

    Rajasthan climate is not one uniform desert type: western Rajasthan is arid to semi-arid, while the east and south are wetter because rainfall and relief change across the state.

  3. 3

    The south-west monsoon provides the main rainy season; western disturbances can bring winter rain locally called mawat, useful for rabi crops.

  4. 4

    19 May 2016: IMD recorded 51.0 degrees Celsius at Phalodi, Rajasthan, as the highest-ever temperature reported in India in its 2016 annual report.

  5. 5

    ISFR 2023 records Rajasthan forest cover as 16,548.21 sq km, equal to 4.84 percent of the state geographical area.

  6. 6

    Keoladeo National Park, Bharatpur, was declared a national park in 1982 and inscribed on the UNESCO World Heritage List in 1985; PIB also records its Ramsar notification in October 1981.

  7. 7

    Khejarli near Jodhpur is the classic community-conservation example: Amrita Devi and Bishnoi villagers are remembered for sacrificing their lives to protect khejri trees in 1730.

Syllabus frame and climate setting

Use only the 2026 CET Senior Secondary syllabus frame for this lesson. The relevant Rajasthan Geography bullets are: climatic conditions, natural vegetation, major soils, natural resources of Rajasthan including forest resources, and wildlife, sanctuaries and conservation. So the lesson should stay with Rajasthan climate, soils, vegetation and conservation examples; it should not drift into Graduation-level India-wide crop, mineral or economic geography.

Rajasthan has a tropical to sub-tropical setting, but the practical exam idea is aridity and rainfall variation. Western Rajasthan is hot and dry because it is far from the sea, lies around the Thar Desert and receives limited effective monsoon rain. The east, south-east and southern hill belts are relatively wetter. Jaisalmer, Barmer, Bikaner and Churu represent the dry west; Jaipur, Ajmer and Alwar are useful semi-arid transition examples; Kota, Baran, Jhalawar, Banswara, Dungarpur, Pratapgarh and Mount Abu show the wetter edge.

The Aravalli range helps explain this pattern. It runs broadly south-west to north-east. The Arabian Sea branch of the south-west monsoon often moves broadly parallel to the range, so western Rajasthan does not receive strong orographic rain. Moisture improves toward the eastern plain, Hadoti and southern Rajasthan. For CET, remember the chain: low rainfall in the west, more monsoon support in the east and south-east, and clear links among climate, soils, vegetation and farming.
