Question

information about contour field bunding

Answer 1

It consists of building earthen embankments across the slope of the land, following the contour as closely as possible. A series of such bunds divide the area into strips and act as barriers to the flow of water, thus reducing the amount and velocity of the runoff.
Contour Bunding are carried out in many parts of India- notably in Maharashtra, Gujarat, Tamilnadu, Karnataka and Andhra Pradesh.
