The Sarasvatī / Ghaggar-Hakra question

Detail

The river identification

• Today's seasonal Ghaggar (in India) continues as the Hakra (in Pakistan) — a single dried/intermittent channel straddling the border.
• NCERTs identify this channel with the Ṛig Vedic Sarasvatī, invoked as a goddess-river described as flowing "from the mountain to the sea" (giribhyaḥ samudrāt).
• Later Vedic and post-Vedic texts record the river's progressive drying up and disappearance, consistent with the archaeological picture of a river losing perennial flow toward the end of the Harappan mature phase.
• Kalibangan, on the left bank of the Ghaggar (locally held to be the ancient Sarasvatī), was excavated by ASI over nine field seasons (1960–69); the mound shows a lower Early/antecedent Harappan deposit (Kalibangan-I) below a Mature Harappan grid-planned town (Kalibangan-II) [2].

Settlement density in the basin

• Per NCERT, nearly two-thirds of all known Harappan settlements lie within the Sarasvatī (Ghaggar-Hakra) basin, not the Indus basin proper — despite the civilisation's name.
• The basin contains two of the five known Harappan "cities" — Rakhigarhi (Haryana) and Ganweriwala (Cholistan, Pakistan) — alongside Mohenjodaro, Harappa and Dholavira, which lie outside it.
• Ganweriwala, identified in the late 1980s, is estimated at over 80 hectares, ranking it among the largest Indus sites [3].
• Rakhigarhi, only partially excavated, is assessed as comparable in scale to Harappa, Mohenjodaro and Ganweriwala [3].
• Smaller cities/towns on the basin include Kalibangan and Farmana; smaller settlements include Bhirrana and Banawali — the latter on the left bank of the dried-up Sarasvatī in present Fatehabad district, Haryana, laid out within a single enclosure wall with winding (non-grid) streets, distinct from Kalibangan's planned layout [3].

Note: ASI/Wikipedia material broadly dates a "strong fluvial Ghaggar-Hakra presence" to well before the Harappan period (cited range extending back to ~5.6 kya and earlier); this pre-Harappan antiquity is additional detail, not a contradiction of the NCERT's Sarasvatī-drying narrative for the historic/Harappan period, and is not asserted here as settled fact.

Prelims Hooks

• Ghaggar (India) = Hakra (Pakistan) = same dried/seasonal river channel, identified with Ṛig Vedic Sarasvatī.
• ~2/3 of Harappan settlements lie in the Sarasvatī (Ghaggar-Hakra) basin, not the Indus basin.
• Of the 5 major Harappan cities, Rakhigarhi and Ganweriwala lie in the Sarasvatī basin.
• Kalibangan — on Ghaggar's left bank, Rajasthan (Hanumangarh dist.); excavated by ASI 1960–69; shows Early + Mature Harappan phases; famous for ploughed field and fire altars.
• Banawali — Fatehabad dist., Haryana, on the dried Sarasvatī; single enclosure wall, winding streets (unlike grid-planned Kalibangan/Mohenjodaro).
• Bhirrana — small Harappan town in the Sarasvatī basin.
• Farmana — smaller Harappan city site in the Sarasvatī basin.
• Ganweriwala discovered late 1980s by Rafique Mughal; ~80+ hectares.
• Vedic/later texts describe the Sarasvatī's drying up and disappearance.

Mains Points

• The Sarasvatī-basin settlement concentration challenges the civilisation's "Indus" naming — argument for the alternative label "Sindhu-Sarasvatī Civilisation."
• River desiccation (Ghaggar-Hakra/Sarasvatī losing perennial flow) is cited among the ecological/climatic factors in Late Harappan decline and eastward settlement shift toward the Ganga-Yamuna doab.
• Links archaeology with textual tradition (Ṛig Veda) — a rare case of a geomorphological identification anchoring a literary reference, used in debates on Harappan-Vedic continuity/chronology.
• Basin-wide urban distribution (Kalibangan, Banawali, Rakhigarhi, Ganweriwala, Farmana, Bhirrana) demonstrates the civilisation was not confined to the Indus valley, relevant to GS-I discussions of Harappan geographic extent.
