Active deep gullies are plugged by digging earth from the bottom as well as gully sides and embanked forming a barrier to runoff passing through it. The embankment is reinforced by planting useful plants such as banana, sesbania, gravillea, gesho, etc., The purpose is to rehabilitate gullies having depth and expand along sides and towards the head. By constructing earth checks the water is stored in the checks. The water percolates down the ground enriching the ground water. The soil is trapped in the checks and later brings up the gully gradient higher. As a result, a cultivable/cropable strip is formed. Weeding and cultivation done to plants established.The gully fence and breaks are repaired. The technology is seen to be suitable to humid highlands where land loss by gully is a serious problem and land under cultivation and grazing is getting here and there. In brief it is suitable in areas where land degradation problem is increasing with currently cultivated and grazed lands are encroched by gully expansion.
