Geography of Punjab

Overview

Geography of Punjab is a high-yield topic for PSTET Paper II Social Studies, appearing regularly in questions about physical features, rivers, doabs, climate and natural resources. Punjab, meaning "Land of Five Rivers," derives its name from the Persian words *panj* (five) and *aab* (water). Understanding Punjab's geography is essential not only for direct questions but also for connecting to agriculture, economy and environmental issues in the state.

The topic requires you to master the five rivers and their associated doabs, the three physiographic divisions of Punjab, the semi-arid to sub-humid climate patterns, and the state's rich agricultural and mineral resources. Questions often test factual recall—river names, doab locations, soil types—so precise memorisation is critical.

Key Concepts

• **Etymology and Location**: Punjab means "Land of Five Rivers." The state lies between 29°30'N to 32°32'N latitude and 73°55'E to 76°50'E longitude, bordered by Jammu & Kashmir (north), Himachal Pradesh (northeast), Haryana (south and southeast), Rajasthan (southwest) and Pakistan (west).

• **Three Physiographic Divisions**: Punjab has three distinct regions—Shivalik Hills (northeast), Plains (central, largest area) and the Semi-desert/Sandy region (southwest towards Rajasthan border).

• **Five Rivers**: The five rivers are Sutlej, Beas, Ravi, Chenab and Jhelum. After Partition, only Sutlej, Beas and Ravi flow through Indian Punjab; Chenab and Jhelum are mostly in Pakistan.

• **Five Doabs**: A doab is the land between two rivers. The five doabs are Bist Doab, Bari Doab, Rachna Doab, Chaj Doab and Sindh Sagar Doab—only the first two lie entirely in Indian Punjab.

• **Alluvial Soil Dominance**: Punjab's plains are covered with fertile alluvial soil deposited by rivers, making it India's granary. Soil types include Bangar (old alluvium) and Khadar (new alluvium near river beds).

• **Semi-arid Climate**: Punjab experiences a semi-arid to sub-humid continental climate with hot summers (up to 45°C), cold winters (down to 0°C in some areas) and monsoon rainfall (July–September).

• **Agricultural Resources**: Punjab is called the "Granary of India" or "Bread Basket of India" due to its high production of wheat, rice, cotton and sugarcane.
