Photo of the farmpond (2-year old) showing the 1:1 side slope steps of 0.6 m dimension and the spilway Inlet cum Outlet. (C.G. Metri, JPO, KWDP Danida)
A farm pond comprises of excavated portions of 12 x 12 x 3 m with the steps at 0.6m depth each. The excavated earth is deposited all around the structure as a bund, with a burm space of 1m. An inlet cum outlet provided in the course of flow of rain water to collect and dispose the excess runoff.
Purpose of the Technology: (1). For storage of exess runoff. (2) to increase percolation for ground water recharge, (3). To use for protective irrigation during dry period, (4). To stop further deepening of watercourse in arable lands
Establishment / maintenance activities and inputs: Selection of beneficiary is by the community and site selection, Design/ layout and excavation by the project staff with participation of the beneficiary. Desilting of the structure is by the beneficiary
Natural / human environment: surrounding lands are more slopy and with exposed rocks, most of the surrounding area is left for grazing

Second crop also taken

Difference in the crop like on bunds and in the patches of crops.
15m x 15m land loss average land holding is very less, thus small & marginal farmers face reduction in the production area with this SWC
After implementing SWC less area is left for very small and marginal land holding.
Subsistance agriculture
To bring new area into cultivation
Water storage in farm pond
