The economic foundation of the Indus Valley Civilization was robust, diversified, and highly organized. Agriculture formed the base, while craft specialization and extensive trade—both inland and overseas—sustained urban growth. The presence of standardized weights, seals, and measurements reflects a regulated economic system essential for managing one of the largest ancient civilizations.

Economic Organisation of IVC with Reference to Agriculture

1. Agricultural Base

• Agriculture was the backbone of the Harappan economy. Farmers practiced floodplain agriculture, sowing seeds in November after floodwaters receded and harvesting wheat and barley in April. Crops grown included wheat, barley, peas, sesame, mustard, millets, dates, grapes, garlic, henna, and rice at Lothal.
• The Harappans were the earliest producers of cotton, referred to as Sindon by the Greeks. Evidence of ploughed fields at Kalibangan and terracotta plough models at Banawali confirms the use of wooden ploughs. Surplus production was stored in massive granaries, particularly at Harappa.

2. Domestication and Resource Use

• The Harappans domesticated cattle, buffaloes, goats, sheep, pigs, camels, asses, cats, and dogs. They were familiar with elephants and rhinoceros but were not a horse-centered culture,. Coastal communities exploited marine resources, with molluscs forming a protein-rich diet in Gujarat.

3. Craft Specialisation

• The civilization excelled in bead making, pottery, metallurgy, shell work, and textile production. Sites like Chanhudaro functioned as industrial centres for bead manufacturing. The use of the lost-wax technique for bronze casting, seen in the Dancing Girl, reflects advanced technological skills.
• Metallurgy involved copper, bronze, tin, lead, gold, and silver. Discoveries such as gold necklaces of 0.25 mm thickness at Lothal and a touchstone at Banawali indicate refined craftsmanship and quality control.

4. Trade Networks

• Trade flourished through land and sea routes. The dockyard at Lothal, possibly the world’s first, highlights maritime trade. Other ports included Sutkagendor, Balakot, and Allahdino. Mesopotamian records refer to Meluhha, identified with the Indus region, exporting cotton, beads, and lapis lazuli.
• Trade efficiency was ensured through standardised cubical weights, rising in a 5:2:1 ratio, and precise measurement tools like the ivory scale of Lothal .

Conclusion
The Harappan economy was marked by agricultural surplus, advanced craft specialization, long-distance trade, and strict standardization. This integrated economic system sustained urban centres for centuries and underscores the Indus Valley Civilization’s position as one of the most sophisticated economies of the ancient world.
