Contour bunds
Placing series of bunds along the natural elevation contour is a way for farmers to promote the formation of rough terraces on sloping lands. The technology aims to control soil erosion, promote water retention, and hence increase crop production in a simplistic manner. Since bunds are permeable structures, they will not pond runoff water, rather they will slow it down to increase the infiltration of water into the soil.
Bunds can be made out of (bundles of) dry vegetative material, stone piles, earth and/or any organic ‘waste’ like weed or crop residues that is locally available. The structures can be stabilized by planting crops or trees in its direct surroundings.
