Deccan Plateau
दक्कन का पठार
The Deccan Plateau covers 500,000 km² of southern India between the Western and Eastern Ghats. Composed primarily of ancient basaltic lava flows, it is a region of rolling hills, river systems, and semi-arid climate that has sustained diverse civilizations and ecosystems.
Key facts
- Area: 500,000 km² covering most of southern India
- Elevation: 300 m to 700 m above sea level, highest points ~1,000 m
- Composition: Precambrian basaltic rock formations, among world's largest lava plateau
- Major rivers: Godavari, Krishna, Kaveri, and Tungabhadra rivers originate/flow through
- Rainfall: 500-1,000 mm annually, drier than coastal regions
- Geology: Part of Indian Craton, one of oldest stable continental regions
Details
The Deccan Plateau dominates the geology and landscape of southern India, formed from massive volcanic activity during the Cretaceous period. Its vast basaltic foundation supports mineral-rich soils suitable for diverse crops including sugarcane, cotton, millet, and pulses. The plateau's undulating terrain is drained by major river systems that originate in the Western Ghats and flow eastward or southward toward the Indian Ocean. Historically, the region witnessed the rise of numerous powerful kingdoms including the Maurya, Chalukya, Chola, and Bahmani sultanates, each leaving cultural imprints. The plateau's semi-arid climate supports deciduous forests and grasslands, creating distinct ecological zones. Today, it remains economically important for agriculture, mining, and industrial development, though deforestation and water scarcity present ongoing challenges.
