Subsistence: agriculture, animals, diet

Detail

Crops and cultivation spread

• Staple grains: wheat, barley, lentil, chickpea, sesame.
• Millets attested chiefly at Gujarat sites — possibly broomcorn millet (introduced from southern Central Asia) and, by c. 2000 BCE, African millets [2].
• Rice rare and regionally confined — recorded at Lothal and Rangpur (Gujarat), attributed to the Late Harappan phase; cultivated vs wild status still debated [2][3].
• Harappans among the first in Eurasia to grow cotton; used for textiles [2].
• Pulses and vegetables also part of diet (Class 6, Ch 6 "The Beginnings of Indian Civilisation").
• Multi-cropping across seasons: summer/kharif sowing (rice, millets, beans/pulses) and winter/rabi sowing (wheat, barley, pulses) — Indus populations credited as earliest in the region to run complex double-season cropping regimes requiring distinct watering schedules [3].

Reconstruction methodology

• Charred grains and seeds recovered from excavation layers, identified and studied by archaeo-botanists.
• Animal bones studied by archaeo-zoologists (archaeo-zoology/zoo-archaeology) — establishes domesticated vs wild fauna ratios.
• Domesticated: cattle, sheep, goat, buffalo, pig.
• Wild/hunted: boar, deer, gharial — unclear whether obtained by hunting or exchange with forager/pastoral groups.
• Fish and fowl remains also present, indicating both riverine/coastal and terrestrial protein sources.

Pot-residue analysis

• Chemical residue studies on pottery interiors reveal dairy processing (milk residues on vessel sherds).
• Surprising finds: traces of turmeric, ginger, banana — implies spice use and possible banana cultivation/exchange far earlier than conventionally assumed for South Asia (Class 6, Ch 6 "The Beginnings of Indian Civilisation").

Agricultural technology — inference chain

• Terracotta figurines and seals depict the bull, read as indirect evidence of oxen used for traction/ploughing (no direct plough survives in most contexts).
• Terracotta plough models recovered from Cholistan sites and Banawali.
• Ploughed field surface at Kalibangan — dated to the Early Harappan period, preserved beneath later mature-phase structures; excavators found it displaying two sets of furrows at right angles, interpreted as evidence of two crops grown together (a proto rabi-kharif intercropping pattern) (Class 9, Ch 4 "Early Humans") — corroborated by ASI's own Kalibangan excavation report describing plough-marked pre-urban surfaces [4].
• Harvesting technology remains uncertain — debate over whether stone blades hafted in wood or metal (bronze/copper) tools were used; no consensus tool type identified archaeologically.

Irrigation and water management

• Harappan zone is largely semi-arid — rain-fed agriculture alone judged insufficient, so irrigation is inferred as necessary though direct field-canal evidence is sparse.
• Shortughai (Afghanistan outpost): canal evidence associated with a Harappan trading colony.
• Wells: widespread across settlements, used for both drinking water and possibly crop-adjacent irrigation.
• Dholavira reservoirs: sophisticated stepped/rock-cut water storage system; the largest reservoir measured c. 265 × 40 ft and 23 ft deep, built to conserve rainwater in a chronically dry Kutch terrain [4].

Food processing

• Saddle querns ("curry stones") used for grinding grain — identified via ethnographic analogy by excavator Ernest Mackay, who compared them to grinding stones still used in contemporary (early 20th century) households.

Prelims Hooks

• Millets concentrated at Gujarat sites; rice is rare and mainly Late Harappan (Lothal, Rangpur) — do not assume rice was a Harappan staple.
• Harappans were among the first in Eurasia to cultivate cotton.
• Charred grains studied by archaeo-botanists; animal bones by archaeo-zoologists — distinguish the two terms in MCQs.
• Domesticated animals: cattle, sheep, goat, buffalo, pig; gharial/boar/deer status (hunted vs exchanged) is unresolved.
• Pot-residue analysis revealed dairy, turmeric, ginger, banana — a favourite "identify the odd one/surprise item" prelims trap.
• Terracotta plough models: Cholistan sites and Banawali.
• Kalibangan ploughed field: Early Harappan date, furrows at right angles → double cropping inference.
• Dholavira: largest known reservoir c. 265×40 ft, 23 ft deep, for rainwater conservation (Kutch, semi-arid).
• Shortughai (Afghanistan) linked to canal/irrigation evidence for a Harappan outpost.
• Saddle querns ("curry stones") — Mackay's ethnographic analogy for grain processing.

Mains Points

• Subsistence evidence illustrates the inference-based nature of Harappan archaeology: absence of direct plough remains or deciphered script forces historians to build multi-strand inferential chains (seals → terracotta models → field furrows) rather than rely on textual confirmation — a useful methodological point for GS-I "sources of ancient Indian history" answers.
• The semi-arid ecology and irrigation response (wells, canals at Shortughai, reservoirs at Dholavira) shows how Harappan settlements adapted infrastructure to regional aridity — link to broader UPSC theme of environment-society interaction in early civilisations.
• Regional diversity within uniformity: while core grains (wheat, barley, pulses) were pan-Harappan, millets and rice show localized adaptation (Gujarat), complicating the older image of a monolithic, homogeneous Harappan economy.
• Double-cropping inference at Kalibangan, if accepted, pushes back the antiquity of rabi-kharif agricultural planning in the subcontinent — relevant for continuity/change debates linking Harappan to later Indian agrarian practice.
