2.1 Short description of the Technology

Definition of the Technology:

It is a structural measure with an embankment of soil or stones or soil and stones, constructed along the contour and stablized with vegetative measures (grass and fodder trees).

2.2 Detailed description of the Technology

Description:

Applied on different land uses on slope of more than 3%. This practice is widely used by farmers in the area. Stone and stone faced bunds height depends on the availability of stones. On the average the width is 1-1.2m and hieght is 0.6-0.7m.

Purpose of the Technology: Bunds reduce the velocity of runoff and soil erosion, retains water behind the bund and let it infiltrate. It further helps in ground water recharging.
