Description of the SLM Technology
Short description of the Technology
Contour trench cum bund is a bund laid out on contour along with trench either staggered or continuous to check the velocity of run off, conserve in situ moisture, increse ground water recharge and there by establish a sustainable land use system.
Detailed description of the Technology
It is a structural measure. The bund is constructed taking the excavated earth from a trench of 1.5m X 0.3m cross section and leaving a berm of 0.3m and put along the contour. Loose boulder water way are constructed on the bund for safe disposal of excess run off.
Purpose: To break the slope of land. To reduce the velocity of runoff. To increase the in situ soil moisture and increase ground water table. To reduce down stream sand casting.
Establishment / maintenance activities and inputs: The process adopted for implementation of the intervention followed participatory planning through resource mapping, transect, well being ranking, problem identification, prioritisation and negotiation; thus benefit sharing, contribution and future maintenance of the stucture is ensured before establishment of the structure. The poor land and poor people get the opportunity first.
