Terracing

noun (uncountable); also present participle/gerund

/ˈter.ə.sɪŋ/

A soil and water conservation technique in which steep hillside slopes are cut into a series of level, step-like platforms (terraces) to reduce surface runoff velocity, prevent sheet and rill erosion, and retain soil moisture for cultivation. Bench terracing (narrow flat steps cut into slopes), contour bunding (raised earthen ridges along contour lines), and broad-base terraces are the principal types. In India, terracing is promoted under the Pradhan Mantri Krishi Sinchai Yojana (PMKSY) and National Watershed Development Project for Rainfed Areas (NWDPRA) as a key measure for watershed management in hilly states such as Uttarakhand, Himachal Pradesh, and the North-East.

✍️ Usage in a UPSC answer

Uttarakhand's degraded watersheds are being rehabilitated through contour terracing and stone-walled bench terrace construction under PMKSY, reversing decades of soil loss that had accelerated flashflood frequency downstream.

🔡 Root

Latin terra = earth, land; -arium → Old French terrasse → English terrace; -ing = process

📜 Etymology

From Old French terrasse (a flat raised platform), derived from Vulgar Latin terrace based on terra (earth). Terracing as an agricultural practice predates written history — the rice terraces of Banaue, Philippines (over 2,000 years old) and Peru's Andean terraces demonstrate its ancient, cross-cultural origins. The English word terrace entered use in the 16th century.

🧠 Memory Hook

TERRACE = TERRA (earth) shaped into stairs. Imagine the hillside as a wedding cake — terracing cuts the slope into flat tiers (tiers = terraces) so that rain stays on each tier instead of rushing all the way down and washing the soil away.
