Kushan Agriculture, Irrigation and Urban Production

The Kushan Empire drew much of its strength from productive landscapes. During the first to third centuries CE, its territories connected the irrigated oases of Bactria with Gandhara and northern India. Farmers, herders and craftspeople supplied food, raw materials and manufactured goods to settlements whose prosperity depended on much more than long-distance luxury trade.

Northern Bactria, in what is now southern Uzbekistan and neighbouring areas, provides particularly useful archaeological evidence. Canals, settlement remains, animal bones, kilns and household objects show how cultivation and urban production worked together. Towns such as Dalverzin Tepe, Termez and Zartepa were places where supplies were consumed, processed and exchanged, as well as centres of religion and government.

Irrigation and the growth of oases

In the relatively dry valleys of northern Bactria, rainfall alone could not reliably sustain all cultivated land. Farmers used irrigation: water was diverted from rivers into channels and distributed to fields. An agricultural oasis was a working landscape of watercourses, crops and settlements.

The development of the Zang canal, carrying water from the Surkhan Darya, supported the Angor oasis around Zartepa. Archaeological study associates this expansion of irrigation and settlement with the Kushan period. Water made cultivation possible in new areas, while a town supplied a place for administration, production and the exchange of agricultural goods.

The principal canal was only part of such a system. Smaller channels had to carry water toward cultivated plots, and the intake and banks had to be maintained. Sediment deposited by the flowing water could reduce a channel’s capacity, so clearing and repairs mattered alongside initial construction. Fields farther from a dependable supply had different possibilities from those close to the main irrigation network.

These differences encouraged several forms of farming. Irrigated oasis cultivation coexisted with farming dependent on rainfall in foothill districts and with the use of moist land near riverbanks. Herding could be combined with crop growing or make greater use of pasture beyond the cultivated oasis. The landscape supported these overlapping activities.

Crops and the work of cultivation

Regional archaeological evidence for the Kushan age includes wheat, barley and millet. Fruit cultivation included grapes and several kinds of stone fruit. Such crops met different needs: cereals supplied staple food, fruit could be eaten fresh or processed, and fodder supported animals used for transport and farm work. Crop choices also depended on the water, soils and growing conditions available in each district.

Cultivation required repeated stages of work. Ground had to be prepared, seed sown, water managed where irrigation was used, and the mature crop harvested. Grain then needed processing and storage before consumption or exchange. The agricultural economy consequently involved tools, containers, transport and labour throughout the year, not just the moment of harvest.

The spread of iron agricultural implements improved the equipment available to cultivators. A wooden plough fitted with an iron share combined a wooden frame with a harder cutting part that opened the soil. It worked differently from a hand-held hoe, which allowed more localized digging and cultivation. The two kinds of tool served complementary tasks.

The agricultural evidence also helps explain the concentration of people in towns. An urban population included officials, religious communities and specialists who needed food produced beyond their own working spaces. Productive surrounding land and the ability to move its output were therefore part of the foundation of urban growth.

Herds, traction and transport

Livestock connected food production with transport and manufacture. Sheep and goats supplied meat, milk and fibres; cattle provided food and could pull farm equipment; horses, asses and camels supported travel or carrying. Hides and wool were raw materials for further work. Keeping animals could therefore serve several household and commercial purposes at once.

Bones excavated at Kushan Zartepa provide a local example. A published analysis found sheep and goats making up about three-fifths of the identified animal remains, followed by cattle at roughly one-fifth. Smaller shares belonged to asses, pigs, horses and camels.

Herding practices varied with the environment. Animals could be kept near homes in settled districts, grazed on plains and foothills, or moved through mountain pasture. The exchange between pastoral and agricultural communities supplied products that each could use. Pack animals also helped move pottery, food and other goods from producers to the towns and routes where they were needed.

Pottery production and local supply

The potters’ quarter at Dalverzin Tepe contained workshops and kilns on the town’s outskirts. A kiln was an enclosed installation in which vessels could be fired at high temperatures. Shaping a pot was only one step: the clay had to be prepared, the vessel dried, and the firing managed so that it emerged sufficiently hard for use.

Potters produced bowls, cups, jars and other forms for different activities. Thin-walled drinking and serving vessels required careful shaping. Larger containers met storage and carrying needs. Red or brown slip, a coating made from fine clay, could give a vessel a finished surface. The quantity and variety of excavated ceramics reflect demand for useful objects as well as the makers’ skill.

At ancient Termez, investigations of Tchingiz Tepe identified a pottery-production installation and studied ceramics from domestic buildings and other excavated areas. Scientific analyses compared the composition and firing of different vessels. The report distinguishes early Kushan material from later Kushano-Sasanian production, associated with the Iranian dynasty that expanded into Bactria after the main period of Kushan imperial power.

Metals, building and exchange

Kushan-period settlements also required metalworkers, builders and makers of ornaments. Surviving moulds reveal the casting of metal objects: molten metal was poured into a prepared form and allowed to cool into the required shape. Other processes, including forging iron and finishing jewellery, called for different materials and skills. Tools, fittings, vessels and adornments had practical uses alongside their value as possessions.

Dalverzin’s excavated houses contained jewellery and, in one case, a substantial gold hoard. Some gold bars were inscribed with their weights in Kharoshthi, a script used in the northwestern Indian subcontinent. The marks connected material wealth with a system of measurement and writing. They complement the workshops and household ceramics by showing a higher-value part of the same urban economy.

Builders used large quantities of sun-dried brick and earth, with wooden beams, vaults and selected stone details. Making and transporting these materials required local resources and skilled work. Temple construction, fortification and large residences generated demand beyond the needs of individual households.

Agriculture, herding and manufacture were thus interdependent. Farms supplied food and some craft materials; towns provided buyers and places of processing; transport joined them together. Long-distance exchange added other opportunities, but the recurring production of grain, animals, vessels, tools and building materials sustained the Kushan world’s settlements from day to day.
