Large numbers of land grants in hitherto non-arable tracts invariably meant expansion of agriculture in early medieval India. How did the management of hydraulic resources (different types of irrigation works) facilitate expansion of agriculture in this period?

Answer:

Early medieval India (c. 750-1200) witnessed agrarian expansion into new tracts, driven partly by land grants to Brahmanas and temples. Effective management of water through diverse irrigation works was crucial to bringing such lands under cultivation.

Land Grants and the Impulse to Expand

• Grants (brahmadeya, devadana) of virgin or non-arable land obliged donees to develop cultivation.
• Temples and Brahmana settlements acted as nuclei organising agrarian production and water control.

Types of Hydraulic Works

Tanks and reservoirs:

• Large tanks (eris) in South India, especially under the Cholas and Pallavas, stored monsoon water for dry-season cultivation.
• The Cholas maintained tank committees and desilting through village assemblies.

Wells, canals and channels:

• Wells (with araghatta/Persian-wheel-type lifts) irrigated the north-west and plains.
• River channels and anicuts (like the Grand Anicut region) diverted water to fields.

Community management:

• Village bodies (sabha, ur) and temples supervised construction, maintenance and equitable distribution.

Impact on Agriculture

• Double-cropping, cultivation of rice and cash crops, and higher yields.
• Settlement of new villages, rise of a prosperous landed order and surplus supporting temples and trade.

Therefore, the management of tanks, wells, canals and community irrigation was the practical basis on which land grants translated into real agrarian expansion in early medieval India.
